Unilateral vs Bilateral Training: Part 1 – Your Comparative Guide

Unilateral vs Bilateral Training: Part 1 – Your Comparative Guide

by | May 19, 2023 | Gym and Strength, Hip, Knee, Lower Back, Return to Sport

We often get asked what are the benefits of one form of exercise versus another. Sometimes this is as simple as discussing the difference between cardio and weights. Today’s article focuses on the difference between a two types of gym based loading programs Bilateral vs Unilateral training. In Part 2, we delve more into some of what the evidence says regarding these modalities.

In general, strength training plays a pivotal role in athletic development, enhancing performance, preventing injuries, and promoting overall fitness. This is especially true for the injured population. As such, our Praxis physiotherapists will discuss with you how your rehabilitation plan will incorporate strength training.

When it comes to strength training though, two primary approaches are often employed: unilateral and bilateral training. Unilateral training focuses on exercises that isolate a single limb or side of the body, whereas bilateral training involves movements that engage both limbs simultaneously. This blog aims to contrast the benefits and drawbacks of unilateral and bilateral strength training methods, examining their impact on athletic performance and overall physical development.

Unilateral Strength Training

Unilateral strength training involves exercises that emphasize working one limb or side of the body independently. One of the significant advantages of unilateral training is its ability to identify and correct muscle imbalances. By targeting each limb separately, athletes can pinpoint weaknesses, imbalances, or asymmetries, and address them with specific exercises. Unilateral training also enhances proprioception and balance by requiring greater neuromuscular control. It activates stabilizer muscles and enhances coordination, which can lead to improved athletic performance and injury prevention.

Moreover, unilateral training allows for greater range of motion and flexibility development, as each limb can move freely without the restrictions imposed by bilateral movements. This can be particularly beneficial for athletes who need to improve mobility and functional strength in specific joints or muscle groups. Additionally, unilateral exercises offer sport-specific advantages by simulating movements that athletes encounter during competition, such as single-leg jumps in basketball, change of direction football or one-arm strokes in swimming.

However, unilateral training does have limitations. It generally requires more time and effort to complete a full-body workout due to the need to perform exercises separately for each limb. Additionally, unilateral exercises tend to involve lower weight loads, which may limit their potential for developing maximum strength.

Bilateral Strength Training

Bilateral strength training, on the other hand, focuses on exercises that engage both limbs simultaneously. One of the primary benefits of bilateral training is the ability to lift heavier weights. This can lead to significant gains in maximal strength and power, making it particularly advantageous for athletes involved in sports that require explosive movements, such as weightlifting or sprinting.

Mid Potion Achilles Tendinopathy Location

Bilateral exercises also promote increased overall muscle mass and hypertrophy due to the higher loading potential. By engaging multiple muscle groups simultaneously, bilateral training can provide a time-efficient method for achieving muscle growth and development. Additionally, the bilateral movements help improve intermuscular coordination, allowing athletes to transfer strength gains more effectively across various activities.

However, bilateral training may not address asymmetries or imbalances as effectively as unilateral training. In some cases, stronger limbs may compensate for weaker ones, perpetuating muscle imbalances and potentially increasing the risk of injury. Moreover, bilateral exercises may not fully translate to specific sport-related movements that often require unilateral actions.

In summary, both unilateral and bilateral strength training methods offer unique benefits and drawbacks for athletes. Unilateral training aids in identifying and correcting muscle imbalances, enhancing proprioception, and improving sport-specific movements. It is a valuable tool for injury prevention and rehabilitation. On the other hand, bilateral training allows athletes to lift heavier weights, develop overall muscle mass, and enhance intermuscular coordination. It is particularly effective for activities that demand explosive power. Ultimately, the choice between unilateral and bilateral training should be determined by an athlete’s specific needs, goals, and the demands of their respective sport. Further, an accurate assessment of any asymmetries that may be present helps to decide where to start. A well-rounded strength training program can incorporate elements of both methods to optimize performance and minimise the risk of injuries.

Treatment Strategies

Physiotherapy plays a pivotal role in the management of Achilles tendinopathy. Treatment strategies focus on reducing pain, promoting healing, and improving function. These will include calf strengthening exercises, stretching routines and activity modification as frontline options. Moreover, physiotherapists can guide patients in proper footwear selection, gait retraining, and implementing preventive measures to minimize the risk of reinjury.

Rehabilitation and Prevention

Rehabilitation programs are essential for individuals recovering from Achilles tendinopathy. Gradual progression of exercise intensity, functional training, and sport-specific drills enable patients to regain strength, flexibility, and proprioception while minimizing the risk of relapse. Educating patients on proper warm-up and cool-down routines, appropriate footwear selection, and regular monitoring of training loads can significantly contribute to preventing Achilles tendinopathy in the future. One of the common errors patients make is making rehabilitation too easy, or returning to sport too quickly. Again, physiotherapy play a pivotal role in ensuring you undertake a graduated return to loading as the application of mechanical stress to the Achilles tendon promotes tendon healing and remodeling.

Conclusion

Achilles tendinopathy requires a comprehensive approach for effective management. As physiotherapists, our knowledge and expertise are invaluable in helping you overcome this condition and return to their active lifestyles.

Plantar Fasciopathy: Understanding how to heal your heel pain

Plantar Fasciopathy: Understanding how to heal your heel pain

by | May 16, 2023 | Ankle and Foot, Running Injuries

Feel like your walking on glass in the mornings?  Those first few steps after a long period of sitting hurt the underside of your heel? Struggling to stand at the end of a long day due to your feet? If so, then you may have plantar fasciopathy, also known as plantar fasciitis. Plantar fasciopathy is a common condition that affects the plantar fascia – a thick band of connective tissue on the bottom of the foot. Plantar fasciopathy commonly affects individuals between the ages of 40 and 60, but can affect almost anyone. In this article, we will delve into the causes, symptoms, treatment options, and preventive measures to help you understand, and more importantly manage, this condition.

Causes and Symptoms

Plantar fasciopathy is often caused by repetitive strain or excessive loading of the plantar fascia, leading to microtears and inflammation. Factors such as overuse, improper footwear, high-impact activities, flat or high-arched feet, and tight calf muscles can contribute to its development. The condition is characterised by sharp pain or a dull ache on the underside of the heel or along the arch of the foot. Pain is typically worse in the morning or after periods of inactivity, and may improve with movement. Standing for long periods or walking on hard floor can also be aggravating.

Treatment Options

The treatment of plantar fasciopathy focuses on reducing pain, promoting load tolerance, and addressing the underlying causes. Physiotherapy interventions play a crucial role in managing this condition. Therapeutic techniques such as manual therapy, stretching exercises, and strengthening exercises can help relieve pain, improve flexibility, and restore foot function. Specifically, improving the windlass mechanism (a phenomena that refers to the tightening of the plantar fascia during the push-off phase of walking or running when you big toe extends). This mechanism helps distribute forces evenly throughout the foot and reduces strain on the plantar fascia. More generally, improvement of the footy intrinsics and plantar flexors more generally have been shown to reduce the severity and duration of symptoms as well.

Additionally, the use of orthotics, taping, or night splints may provide support and alleviate symptoms. Extracorporeal shockwave therapy (ESWT) and ultrasound therapy are also viable treatment options in some cases. In severe or persistent cases, corticosteroid injections or surgery may be considered, though this is usually reserved for when conservative measures have failed.

Preventive Measures

Prevention is key to reducing the risk of plantar fasciopathy starting in the first instance. If you are keen to ‘pound the pavement’ for example, then gradually increase activity levels. Avoid sudden changes in intensity or duration to prevent overloading the foot. This may mean dancing long bouts for the first time in a while, or returning to running post injury. Wear footwear that provides adequate arch support and cushioning. Understand the importance of regular stretching exercises for the calf muscles and plantar fascia.

As physiotherapy professionals, we understand that addressing the symptoms of plantar fasciopathy early is essential for providing effective care. At Praxis, effective care means arming you with adequate advice and education so you can help manage the symptoms yourself. Further, implementing appropriate treatment options and emphasizing preventive measures, we support individuals in overcoming foot pain and restoring quality of life. After all, we aim to Prevent, Prepare, Perform! So if you have heel pain that is stopping you from doing what you would like to do, discuss it with our knowledgeable team today!

Stress Fractures in Young Cricket Fast bowlers: A persistent challenge

Stress Fractures in Young Cricket Fast bowlers: A persistent challenge

by | May 16, 2023 | Lower Back, Return to Sport

Lumbar stress fractures are one of the most serious and persistent injuries affecting cricket fast bowlers, especially in adolescents. The repetitive, high-load forces of the bowling action place significant strain on the lower back—particularly the L4 and L5 vertebrae—leading to stress fractures in up to 15–30% of elite junior bowlers. While not the most common cricket injury, they are among the most severe, often sidelining players for 3–6 months—much longer than soft tissue injuries like side strains or hamstring tears. Drawing on my years of experience in cricket physiotherapy, I’ll break down the causes, symptoms, treatment, and prevention of this typically season-ending injury.

Causes and Symptoms:

Lumbar stress fractures in fast bowlers are primarily caused by the high volume of repeated lumbar extension, side flexion, and rotation involved in the bowling action—especially during the delivery stride and follow-through. This repetitive mechanical load places excessive stress on the pars interarticularis, a small but critical bony structure in the lower spine. Over time, microtrauma accumulates and can progress to a stress reaction or fracture, particularly in adolescent bowlers whose bones are still maturing and whose core and hip musculature may lack the strength and control to absorb the forces effectively.

Symptoms typically develop gradually and may include deep, localised lower back pain that worsens during or after bowling, along with stiffness, tenderness to palpation over the lumbar spine, and occasionally pain with hyperextension or single-leg loading tasks. Pain is typically on the opposite side of the bowling arm. Early recognition is key, as continuing to bowl through pain may worsen the injury and extend time away from sport.

Diagnosis:

Lumbar stress fractures are best diagnosed through a combination of clinical assessment and imaging. Clinically, a history of progressive lower back pain in a young fast bowler—particularly pain aggravated by lumbar extension or single-leg loading—is highly suggestive. While plain X-rays are often inconclusive, MRI is the gold standard for early detection. Specifically, THRIVE or VIBE sequences are highly sensitive for identifying bone stress reactions and early pars defects, often before a fracture line is visible. These sequences provide high-resolution, fluid-sensitive imaging that helps detect bone marrow oedema and subtle cortical changes, enabling early intervention before the injury progresses.

Treatment and Rehabilitation:

The management of lumbar stress fractures requires a comprehensive approach. Initially, rest and avoiding activities that exacerbate the pain are essential to allow the bone to heal. A period of complete rest from bowling, coupled with appropriate pain management is usually recommended. A structured rehabilitation program focusing on core stability, flexibility, and strengthening exercises on the lumbar spine, pelvis and lower limbs is crucial for a safe return to bowling. Once a players has reestablished the requisite physical attributes, a graduated bowling plan is established.

Typically, the timeframes vary but follow this timeline

  • Phase 1: Protection & Pain Control – Weeks 0–4 (up to 6 if acute)

  • Phase 2: Early Rehabilitation – Weeks 4–8

  • Phase 3: Progressive Loading – Weeks 8–12

  • Phase 4: Return to Running/Sport Prep – Weeks 12–16

  • Phase 5: Full Return to Sport – ~Weeks 16–20 (or longer for high-load sports)

Prevention Strategies:

Prevention is key in mitigating the risk of lumbar stress fractures. Fast bowlers should maintain a balanced training regime that includes multi-joint strength training, flexibility exercises, and proper warm-up and cool-down routines. Regular monitoring of workload and ensuring adequate recovery time between bowling spells can also minimize the likelihood of injury. Of particular note, is avoiding back to back days of fast bowling in adolescent cricketers.

In summary, lumbar stress fractures pose a significant challenge to cricket fast bowlers, especially those in their teen years or as they transition to junior cricket to senior cricket. A diagnosis typically requires extensive time away from bowling and requires a targeted rehabilitation plan and a cautious return to the sport. By understanding the causes, recognising the symptoms, and implementing effective prevention and strengthening strategies, bowlers can continue to bowl fast and trouble the batsmen down the other end!

If you wanting to minimise your risk of a stress fracture, or think you may have one, feel free to consult with one of our expert physiotherapists, well versed in the cricket literature.

Understanding Sever’s Disease: A Common Foot Condition in Active Growing Children

Understanding Sever’s Disease: A Common Foot Condition in Active Growing Children

by | May 16, 2023 | Ankle and Foot, Return to Sport, Running Injuries

Understanding Sever’s Disease in Growing Children

Sever’s disease — medically known as calcaneal apophysitis — is a common heel condition affecting active children, especially during growth spurts. Despite its name, it’s not a “disease” in the traditional sense, but an overuse injury of the growth plate at the back of the heel.

What Causes Sever’s Disease?

Sever’s disease develops when repetitive stress irritates the growth plate in the heel bone (the calcaneal apophysis). During adolescence, especially between ages 8–15, the heel bone may grow faster than the surrounding muscles and tendons, causing excessive tension at the Achilles insertion site. When coupled with repetitive impact — such as running, jumping, or playing on hard surfaces — this mechanical overload leads to inflammation and pain.

It’s especially common in sports like soccer, basketball, AFL, netball, and gymnastics. Kids going through growth spurts, or who are highly active without sufficient recovery, are most at risk. Tight calf muscles, poor footwear, and biomechanical factors like flat feet or poor shock absorption may also contribute.

Common Symptoms

The main symptom is heel pain that worsens during physical activity and settles with rest. Children may complain of:

  • Pain or tenderness at the back or underside of the heel

  • Limping or toe-walking, particularly after sport

  • Discomfort when pressing on the heel or squeezing it from both sides

  • Stiffness first thing in the morning or after periods of inactivity

Symptoms are usually one-sided but can be bilateral. If left unaddressed, the pain can start to interfere with participation in sport and physical education at school.

Diagnosis

A diagnosis is usually made through clinical history and physical examination by a physiotherapist. Key indicators include heel pain during activity, recent growth, and tenderness at the posterior heel. The “squeeze test” — applying gentle pressure to both sides of the heel — is often positive.

Imaging (X-ray or MRI) is rarely needed unless symptoms persist longer than expected, or there is suspicion of another diagnosis. Importantly, a visible growth plate on X-ray in this age group is normal and not a reason for concern in itself.

Treatment and Management

Treatment is focused on reducing inflammation, offloading the heel, and supporting the child’s return to normal function. It is important to reassure both child and parent that this is a temporary, self-limiting condition.

Key management strategies include:

  • Load modification: Avoiding or reducing high-impact activity is key, especially sports with frequent jumping or sprinting. Your physio can help create a weekly plan to reduce flare-ups while keeping your child engaged and active.

  • Ice: Icing the heel after sport can reduce inflammation and pain, especially in the early stages.

  • Heel lifts or orthotics: Studies, including the 2016 randomised trial by James et al., show that both orthotic devices and cushioned heel lifts can effectively reduce heel stress. These inserts help absorb shock and reduce Achilles tendon tension.

  • Calf stretching and strengthening: Tight calf muscles increase load on the heel. Scharfbillig et al. (2008) emphasised the role of flexibility programs, particularly eccentric calf training, in improving outcomes.

  • Footwear advice: Supportive, well-fitted athletic shoes are essential. Avoid barefoot running or flat-soled footwear during recovery.

  • Manual therapy and taping: In some cases, hands-on techniques and taping methods may be used to reduce load on the Achilles insertion.

According to the trial by Weert et al. (2016), physical therapy combining load management and exercise-based rehab was just as effective as orthotic devices. This supports a flexible treatment approach tailored to the child’s specific needs and activity level.

Medication: Short courses of anti-inflammatory medication such as ibuprofen can help in more severe cases, especially when pain interferes with sleep or daily function. However, these should always be used under medical advice.

Prevention and Long-Term Outlook

The prognosis for Sever’s disease is excellent. Most children recover fully once the growth plate fuses — typically by age 15 for boys and 13 for girls. The condition does not cause permanent damage, though symptom duration can vary from a few weeks to several months depending on activity levels and adherence to management.

To reduce the risk of recurrence:

  • Encourage a proper warm-up and cool-down routine

  • Ensure sport participation is balanced with adequate rest

  • Maintain calf flexibility and foot strength

  • Use shock-absorbing shoes or orthotics during growth spurts

  • Avoid large increases in training volume or intensity

It’s also helpful to educate kids and parents that some discomfort during growth phases is normal, but persistent pain warrants a review. At Praxis Physiotherapy, our clinicians are experienced in managing growing athletes — and ensuring they don’t miss more game time than necessary.

Summary

Sever’s disease is a common and manageable cause of heel pain in growing children. Early recognition, temporary load reduction, and a guided rehab program can ensure a smooth recovery and quick return to sport. If your child is experiencing heel pain that isn’t improving with rest, book in with the friendly and knowlegable team at Praxis Physiotherapy for a tailored management plan.

Knee Osteoarthritis: Is ‘Bone on Bone’ a painful life sentence?

Knee Osteoarthritis: Is ‘Bone on Bone’ a painful life sentence?

by | May 16, 2023 | Knee, Osteoarthritis, Pain, Surgery

  • Knee Osteoarthritis is a common ailment responsible for pain, loss of function and reduced quality of life
  • Rates of knee OA are set to increase
  • Whilst there is no cure, exercise therapy under the guidance of a physiotherapist is considered a front line treatment to help reduce the severity of symptoms
  • There are options before a knee replacement

Do your knees go crackle and pop? Pain with walking, stairs or getting out of a chair? Stiffness and pain first thing in the morning or after a long car ride? These are signs that you may be living with the early or even advanced symptoms of knee osteoarthritis (OA). Don’t fear though – there is plenty that can be done immediately.

What is “OA”?

Osteoarthritis (OA) is an increasingly prevalent source of musculoskeletal pain and dysfunction. OA is a disease of the joint – including cartilage, bone, capsule and other associated tissues. This disease process can cause chronic pain, reduced physical function and diminished quality of life. The ageing population and increased global prevalence of obesity are anticipated to dramatically increase the impacts of knee OA and its associated impairments [1]. Although osteoarthritis can affect any joint, OA is knee is one of the most common complaints.

Presentation

It most commonly presents in people over the age of 50, and is often described as being painful, stiff and occasionally swollen. In terms of a tissue level, knee OA describes the gradual deterioration of the supportive cartilage within the knee joint. As the cartilage wears away with time, the protective joint space between the bones decreases. With a reduced cartilage lining to protect and support the spacing of the knee joint, the Femur and Tibia (knee bones) are increasingly less likely to dissipate forces through the joint . With time, it should be expected that bone spurs (osteophytes) may form in and around the joint as the bones react to repetitive contact with each other.

Management

The management of knee OA largely consists of exercises addressing strength, range of motion, quality of movement, emphasizing joint control, pain reduction and weight management.

Strength Training

Strength training should be the cornerstone of addressing knee OA, particularly the early signs. Strengthening the muscles around the knee joint, such as the quadriceps, hamstrings, and glutes provide better support to the knee, reducing stress on the joint and helping to alleviate pain and discomfort. Movement associated with exercise has an added benefit – It increases joint lubrication. Loading of the joint stimulates the production and distribution of synovial fluid within the joint. This fluid acts as a lubricant, reducing friction and providing cushioning to the joint surfaces. Improved lubrication can help alleviate pain during movement.

Range of motion

Knee osteoarthritis often leads to stiffness and limited range of motion in the joint. Physiotherapy can include specific exercises, manual therapy and stretches to improve joint flexibility, helping to restore a more normal range of motion and enhancing mobility. The greater the restoration of range, the better the knee feels.

Pain reduction

Both strength training and physiotherapy can help reduce pain associated with knee OA. As mentioned, stronger muscles provide better support to the joint, relieving pressure and reducing pain during movement. Physiotherapy may provide education of aggravating and easing factors (eg. hot / cold packs, hydrotherapy) as well as liaise with your GP for adequate analgesic medications.

Lifestyle modifications

Adopting a healthy lifestyle can play a pivotal role in managing knee osteoarthritis. Maintaining a healthy weight reduces the stress on the knee joints. Regular low-impact exercises such as swimming, cycling and reformer pilates help improve strength, flexibility, and overall joint health. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can promote weight loss and provide essential nutrients for joint health. Quitting smoking and minimizing alcohol consumption are also beneficial.

Improved weight management

Regular exercise can assist in weight management, which is crucial for individuals with knee osteoarthritis. Excess weight puts additional strain on the knee joint, contributing to pain and progression of the condition. By maintaining a healthy weight, exercise helps to reduce the load on the joint and alleviate pain.

Surgical Interventions

When conservative measures fail to provide relief, surgical interventions may be necessary. Procedures such as arthroscopy, osteotomy, and joint replacement surgery can help repair damaged tissues, realign the joint, or replace the damaged joint with a prosthetic. These surgeries can significantly improve mobility and reduce pain, allowing individuals to resume their daily activities. Physiotherapy can aid in preparing you for the surgery, as well as rebuild your “new” knee after a knee replacement has been completed.

In conclusion, while knee osteoarthritis can be challenging, it is not a condition that should hinder individuals from leading fulfilling lives. By implementing lifestyle modifications, exploring various treatment options, and working closely with your physiotherapist, individuals can effectively manage their symptoms, alleviate pain, and enjoy an active lifestyle with a sense of well-being. If conservative options fail, there are surgical interventions that can be investigated.

Tibialis Anterior – The missing link to pain free legs and performance?

Tibialis Anterior – The missing link to pain free legs and performance?

by | May 16, 2023 | Ankle and Foot, Return to Sport, Running Injuries

Shin splints? Painful knee with jumping? Recurrent ankle sprains? These are the types of injuries we fix day in and day out at Praxis Physio. There are number of recommended paths for rehabilitation in theses injuries backed by the research and our clinical experience, but has the evidence been missing something? There is some social media traction in the fitness and exercise world recently around tibialis anterior (TA) loading as a ‘cure all’ for every lower limb injury. Being the physio nerds that we are, we looked in to it for you!

The tibialis anterior is located on the front (anterior) portion of the shin (tibia) – hence the name. Its role is to lift the foot (dorsiflex) the ankle as well as provide some stability for the outside of the ankle . This action is key for movements in walking and running especially in negotiating steps and hills as the foot needs to clear a certain height before landing. It is also very important in landing from a height and changing directions rapidly, as it acts as shock absorber for the knee and ankle joints (reference).

Like any muscle or joint in the body, the TA is not without its problems. Physios are regularly confronted with patients who complain of pain and stiffness around the muscles of the shin. Such conditions may include shin splints, compartment syndrome, patellofemoral pain syndrome (aka runner’s knee) and general ankle joint pain and stiffness post ankle sprain.

As mentioned, there has been a lot of discussion lately in the strength and conditioning community about whether training this muscle can prevent or treat musculoskeletal conditions, such as the ones mentioned above. Anecdotally, training of the TA has been described several benefits. Specific athletes have explained that they have seen improvements in vertical jump height, running speed, running stamina and squat depth. From a prevention and treatment point of view, it has been said that training the TA has helped improve symptoms associated with knee pain, ankle pain and shin splints. Also let us not forget, that from an aesthetics point of view, a strong and bulky looking TA does make our legs look more attractive, as bodybuilders would argue.

Unfortunately, the scientific community has not provided strong evidence that training the TA can aid in affecting the above musculoskeletal pathologies, or attain the performance benefits. So what do we know from previous scientific literature? Well, Munoz et al (2015) describes the tibialis anterior as key during an efficient gait cycle as well as being critical for balance control. Furthermore, an increase in strength of the TA helps greatly reduce the risk of falling. Maharaj et al (2019) confirms that during walking and running , TA’s tendinous tissue absorbs energy during contact and controls foot position during swing.

The proposed mechanisms to aid in athletic performance include:

  1. Increased ankle stability: Strong tibialis anterior muscles provide better stability to the ankle joint during jumping movements. This stability allows for improved force transmission from the lower leg to the foot, enabling athletes to generate greater power and maintain proper alignment during takeoff and landing.
  2. Enhanced dorsiflexion range of motion: Adequate dorsiflexion range of motion is essential for optimal jumping performance. Strengthening the tibialis anterior helps to improve flexibility and mobility in the ankle joint, allowing athletes to achieve a greater degree of dorsiflexion during the pre-jump phase. This increased range of motion enables a longer and more powerful push-off, resulting in higher jumps.
  3. Improved jump height and explosive power: The tibialis anterior plays a significant role in generating propulsive force during the takeoff phase of a jump. By strengthening this muscle, athletes can produce a more forceful and efficient push-off, leading to increased jump height and explosive power. The ability to generate greater force through dorsiflexion contributes to a more powerful and effective jump.
  4. Injury prevention: Weak tibialis anterior muscles can contribute to imbalances in the lower leg, potentially leading to various conditions such as shin splints or ankle sprains. Strengthening this muscle group helps to maintain proper muscle balance around the ankle joint, reducing the risk of injuries that could hinder jumping performance.

So if we are to believe TA holds the key to athletic performance and injury mitigation, how do we unlock it?

To strengthen the tibialis anterior, physiotherapists often prescribe specific exercises that target this muscle, such as toe raises, resisted dorsiflexion exercises, or using resistance bands to provide resistance during dorsiflexion movements. These exercises should be performed in a controlled manner and progressively increased in intensity to promote muscle strength and endurance. Below you see variations on how you can load the TA and progress and regress it respectively. Remember that we need to treat the TA like any other muscle we are wanting to train – progressively overloading it!

As Physiotherapists, we greatly value and adhere to evidence-based practice, however one could argue that this particular muscle has not received the scientific study treatment it rightly deserves. So if you are having some lower leg issues, or haven’t quite got that bounce you are wanting, come and chat to one of our friendly and knowledgeable staff. We can do a full assessment and put the spring back in your step!

I need to get an MRI to help with the management of my lower back pain

Answer – FICTION

In a recent narrative review, Wang and colleagues (2018) concluded that MRI imaging in the early stages of lower back pain can have detrimental effects including more pain, less improvement, higher risk of surgery and worse overall health status. In fact, one study reported that patients that received an MRI within the first month had an 8x greater risk for surgery and 5x more medical costs!

If you do NOT present with severe neurological deficits, signs of a serious or specific underlying condition or have persistent pain >6 weeks which is unresponsive to conservative treatment then there likely isn’t a need for further investigation!

Blood Flow Restriction – more than just a gimmick?

Blood Flow Restriction – more than just a gimmick?

by | Oct 11, 2022 | ACL, Gym and Strength, Knee, Reformer Pilates, Return to Sport

Summary:

  • Restriction of blood flow purportedly creates an internal environment of greater stress, thus greater adaptation
  • Importantly, the greater adaptation can occur with less absolute load to damaged or painful tissues
  • Started in healthy population to build muscles but the principles are transferable to rehabilitation
  • Best suited persons who are unable to tolerate normal load
  • Post surgery, tendinopathies and people needing to arrest atrophy or build muscle fast are best candidates

Blood flow restriction (BFR) training is becoming increasingly popular in rehabilitation and conditioning settings. As the name suggests, BFR training incorporates a restriction of blood to an area paired with low resistance training (20-50% of 1 rep maximum). The principle is to achieve greater muscle strength and hypertrophy gains for healthy and load-compromised populations with the same or less load than without a cuff. Essentially – more bang for your buck in the early phases of rehabilitation!

Benefits of BFR include; prevention of muscle mass in early post-operative periods, similar benefits of muscle mass and strength as heavier resistance training in achilles tendinopathies (>70% 1RM) (Centner et al, 2019), and improvement in maximum voluntary torque.

 

Whilst research is still being developed, multiple studies have been conducted recently showing the benefits of BFR training in post-operative populations ie. ACLR, patella / achilles tendinopathies, as well as knee osteoarthritis and patellofemoral pain syndrome.

Here at Praxis Physiotherapy, we have used a BFR cuff paired with low-resistance training on the reformer pilates and in the gym to optimise the distal quadriceps strength post ACL surgery. As you can see we are putting to the distal quadriceps to fatigue under a small amount of load, thus preventing muscle loss (Prue, et al. 2022) which can be common postoperatively.

General prescription guidelines according to the Australian Institute of Sport recommend that “the application of BFR should be limited to less than 20 minutes for lower limb, and 15 minutes for upper limb, before allowing adequate time for reperfusion of tissues (3 min).” (AIS, 2022).

In summary, this is an exciting new area of research that we are investigating clinically. Anecdotally, we hear from patients that they fatigue earlier in the desired muscle groups. We as a Praxis Team are embarking on some in clinic research in the area and hoping to provide feedback on our experiences so keep your eyes peeled. In the meantime, if you are pre or post your operation and are looking to maximise your recovery, come and have a chat with us about whether BFR is suitable for you!

Jumper’s Knee (Patellar Tendinopathy)

Jumper’s Knee (Patellar Tendinopathy)

by | May 17, 2022 | Knee, Return to Sport, Sports Injury, Tendon

Do you play a jumping sport such as volleyball, basketball or AFL? Have pain in the front of your knee when jumping, landing or changing direction? Have you lost some jumping power recently? Well read on friends as you may have a grumbly knee tendon.

Summary:

  • Patellar tendinopathy is summarised clinically as pain and dysfunction in the patellar tendon
  • Most commonly affects jumping athletes from adolescence to early middle age.
  • Return to sport can be slow with physio useful as a front line management tool
  • Often requires prolonged rehabilitation centred around education, strength training and load management

Jumper’s knee (or patellar tendinopathy) as its name suggest predominantly affects athletes who engage in sports which require large volumes of jumping. Jumping dynamically loads the knee and places large loads on the patellar tendons due the large and repeated requirements of the thigh muscles (quadriceps). These include sports that require repeat jump / landing efforts and/or high volumes of load during training and competition. Elite adolescent male athletes tend to be at a higher risk, especially if you play volleyball.

Mid Potion Achilles Tendinopathy Location

Like most injuries, patellar tendinopathy reflects an overload of the tissue and a failed healing response. Tendons tend to most susceptible to long periods of dynamic loading given their role in storing and releasing energy like a spring. The stiffer the spring, the more effective the spring and the more punishment it can take before the function deteriorates.

This injury is one that can be mild or moderate in nature and as such allow playing to some degree. As such, player’s tend to not to miss a lot of games like more “traditional” injuries such as ankle sprains or hamstring tears. It can typically slowly present and have a “warm up phenomena” (as in it can get better during a game), however aches after activity and the next morning. The pain is often at the very bottom of the knee cap, and on the space between the kneecap and the top of the shin bone where the tendon lies.

Key management strategies include ensuring the correct diagnosis and an understanding of tendon pathology (for more on tendon pathology, check out this blog). From there, pain management strategies and workload management is a key tenant to rehabilitation. Above and beyond workload management and good patient education, we at Praxis Physio also test the strength and range of the hip, knee and ankle musculature as well as jumping / landing biomechanics to understand where the likely reasons are for your knee pain.

After a comprehensive assessment, targeted and graduated strengthening is provided. The premise of these early phases are to reduce pain, improve strength, improve function, increase power (specifically the energy storage potential of the tendon) then finally sports specific training and management on symptoms.

As someone who has had an 18 month history of patellar tendinopathy, I personally can attest to the frustration this injury provides. I made many mistakes along my rehabilitation journey – though this was before I was a physiotherapist and took a clinical interest in tendinopathies. Thankfully, the research has come a long way in the last decade, so if you are having ongoing knee pain that you suspect is jumper’s knee, book in with us so we can get you jumping back to your best.

Until next time, Praxis what you Preach.

Peri-Menopause and injury – your guide to the most common issues

Peri-Menopause and injury – your guide to the most common issues

by | Mar 17, 2022 | Gym and Strength, Reformer Pilates

  • Menopause alters hormones and results in physical changes
  • These changes typically result in increased injury risk or activity reduction
  • The most common injuries affect structures such as the plantar fascia, tendons of the hip and shoulder
  • Appropriate exercise and judicious hands on therapy should be cornerstones of management
Betty Friedan said it best when she said “Aging is not lost youth but a new stage of opportunity and strength.” If only our bodies would play the game and come along for the ride as Betty wishfully thought. Age related transitions such as menopause often results in physiological changes (as outlined in other blogs) is an increase in weight, a loss of muscle and bone mass and a drop in physical activity. Not something anyone would wait in line for. A spiral of further activity loss, deconditioning and ultimately, injury can easily occur as a result. As a physiotherapist who looks after everyone from elite athletes, to weekend warriors to desk jockeys, I see the frustration injuries cause my patients (and myself!). So, in the interests of helping you enter the chapter of “opportunity and strength”, these are the most common injuries I see on a daily basis in perimenopausal women and what to do about them.

Heel pain – Plantar fasciopathy (the injury formerly known as plantar fasciitis)

Heel pain can be a number of things. The heel pain that I tend to see the most of is the one that feels like you are walking on glass the first thing in the morning or after you have been sitting down for a while. It makes you walk like your Grandma used to for those first few steps and the thought of doing a long walk, or heaven forbid wearing heels, gives you the sweats.

This pain is usually characterized by a condition called plantar fasciopathy. The plantar fascia is designed to help to absorb, store and transfer force during walking, running and jumping activities. Collagen (the main protein based building blocks of the body) is a non contractile tissue that sits on the underside of your foot. The attachment point for this tissue, is you guessed it, on the bottom of your heel where that “burning glass” feeling .

Plantar fasciopathy loves the status quo. It likes loading the same way, at the same intensity, at the same volume day in day out. Pain and dysfunction is brought about typically in a sudden increase in dynamic loading, whether that is walking, running or jumping. This often happens with women hell bent on a health kick to lose those extra kilos. With the shoelaces tied, lycra on and the world your oyster, some women start at where they remember they left their exercise behind, often several years (and children) ago. The resultant spike in load, particularly dynamic loading coupled with musculoskeletal detraining, is what kicks off the pain as the plantar fascia gets overloaded more easily and grizzles about it.

Key tip – Start slow with walks – not running – if it has been a while since you last exercised. Progress to jogging with some walk intervals in there (e.g 30s jog, 90s walk). Do calf raises (eg. 3 sets to a feeling of semi-fatigue) to get more calf strength as this can help deload the plantar fascia.

Outside / Lateral hip pain (Gluteus medius tendinopathy)

The muscles on the outside of your hips are designed to help keep your pelvis level when you are walking or running. This area is a particular passion of mine given my masters thesis was based on the single leg squat. Similar to the plantar fasciopathy, gluteal tendinopathies tend to be an injury that I see when people go too hard, too quickly. This results in outside hip pain that hurts rising from a chair, walking up stairs or even lying on that side at night.

The human instinct is to rest, but tendinopathies don’t work that way, in fact it is the opposite. The only way to adequately address issues such as gluteal tendinopathy is getting on top of your workload. Ensure you are graduating whatever activity you are re-engaging in appropriately, and you have the strength to do so. I typically use a hand held dynamometer in my clinic to assess someone’s strength to give me accurate numbers to work with. However, a rough guide is that if you can do a side plank for 30 seconds, you need some more hip strength.

Key tip – Workload management and pain management are paramount. If in pain, reduce loading and focus on strength. Lying hip lifts (e.g. 10 x 10 sec holds) are good when pain is acute. If not sore (just weak), side plank with top leg lifts are a good option to start. 3 x semi-fatigue each side. We employ reformer pilates often in this space but gym based activities are also appropriate.

Shoulder Pain – “Rotator Cuff” tears / tendinopathy

Do you have a ‘good’ and ‘bad’ shoulder? Have you been putting up with that grumbly shoulder for weeks, months or even years? Shoulder pain can put a real dampener on activities where repetitive overhead dynamic loading is common (e.g weights, tennis, golf or boxing).

The “rotator cuff” is a group of four muscles that help provide stability and control of the shoulder joint through range, particularly overhead. Rotator cuff tears are common in individuals over the age of 40 with linear increase in incidence as we get older. The most common reason for rotator cuff tears are due to overactivity of the shoulder joint coupled with deconditioning of the shoulder complex. Pain with movement and function is one of the biggest symptoms of a rotator cuff pathology.

Key Tip – Look at how much overhead activity you are doing and adequately prepare for it. This is best achieved in my experience with something like a banded Y Press hold (10x10s holds daily for a month) then progressing to more dynamic activities.

All in all, changes associated with menopause can leave you open to more injuries. However, if you can appropriately navigate, and most importantly graduate, your return to physical activity, then your body will certainly pay you dividends down the line. The evidence is overwhelming for the positive influences physical has on the human body. So do yourself (and your future self) a favour and ensure you aren’t retreating from your physical activity goals due to injury. It’s not what Betty would want.

If you have some of the above aches and pains, feel free to reach out or book in with one of our expert therapists.

Until next time, Praxis what you Preach.
