FACT OR FICTION FRIDAY || Overuse injuries need rest and are because I’m doing too much

FACT OR FICTION FRIDAY || Overuse injuries need rest and are because I’m doing too much

ANSWER: FICTION (Mostly – stay with us here) 🙊 Do you keep getting injured when you get back into your usual training after a period of rest 😤? The first graph shows a 65-day cycle of an Olympic athlete. The red lines indicate when the athlete was injured. Looking at the multi-coloured line, you can see that the injuries both occurred when the acute to chronic workload ratio was at its peak. Essentially that means that the loads that preceded the injury were too high relative to the longer term loading of the tissue 😫. This is typically called an overuse injury! Then along comes Mr/Ms physio and looks at the above cycle and says to the Olympian, “Come on mate, we can do better than this…” 😎 Ta da. The second graph shows the yellow section outlining the above 65-day period.

As you can see, training following this period is much more frequent and at higher intensities. So do we still assign the original injuries to overuse injuries given the athlete was able to handle much more relatively quickly after?! A better term would be a training load error and something that a sporting physio can help you with 👌. This is a particularly important thing to know given the holidays are just around the corner 🎅!

Shin Splints | Physio Guide to Medial Tibial Stress Syndrome

Shin Splints | Physio Guide to Medial Tibial Stress Syndrome

SUMMARY

  • Shin splints are essentially an overuse injury
  • Numerous factors contribute to symptoms but mainly involving the poor control of force through the lower limbs
  • Important to stop symptoms to avoid developing stress fractures, which require lengthier time away from activity
  • Corrective strengthening exercises, relative rest, and workload management all seem to be treatment mainstays
  • Physiotherapy has a significant role to play in getting back to running and sport
Mid Potion Achilles Tendinopathy Location

SHIN SPLINTS

Shin splints, or as it’s referred to as in the literature, medial tibial stress syndrome (MTSS), is a common injury seen in the recreationally active and army populations. Symptoms typically consist of an aching pain to the lower medial (inside) part of the shin, that can be sharp when running or when inflamed. There can also be some pain and stiffness when you first walk around in the morning, or when you first start your activity.

Risk Factors:

Over 100 potential intrinsic risk factors of MTSS were identified in a recent systematic review [1] involving 21 different studies. Of those risk factors, nine were identified as having a moderate to strong occurrence in clinical practice. Out of these nine, the risk factors that result in the greater loads on the body (such as body mass index) or poorer acceptance of load with running were the most important.

A number of range of motion parameters were also identified. For example, larger plantar flexion range of motion (the movement of pointing your foot down) was identified. It has been hypothesized that the increased plantar flexion results in a greater likelihood of the individual landing on their forefoot rather than their rearfoot while running, possibly increasing the strain on the rear inside leg (posteromedial tibia). Forces on the inside of the shin bone explain the why pain may be present in that area.

Treatment:

Most people tend to simply rest which may decrease symptoms in the short-term, but it doesn’t address the direct cause! The condition is very commonly seen in recreational runners and not as much in your higher-level athletes. Why is this? It’s quite simple! As mentioned in our previous running blogs, the adherence to well-planned running workloads is what separates recreational runners from the competitive or non-injured. Planned training leads to adequate adaptation of the body to the demands placed upon it.

One of areas patients with shin splints focus on is poor “foot posture”. It is very common to hear the same old story, “I have shin splints because my feet are flat, I need orthotics to correct that”. The biggest problem with that approach is that not a lot of people realise that the reason that they are flat footed is not necessarily because of a defect in their feet! It may be because they have strength and control of their hips which is in turn is causing over pronation or flattening of their feet.

The diagram below demonstrates that perfectly!

As the hips cannot stay level during running, this may cause the knees to fall inwards and in turn causes pronation or flattening of the foot. Then, voila! You have increased tractional stress on the medial aspect of the tibia/shin bone. Yes, there is some evidence that poor foot posture can cause the problem, but only in combination with extrinsic risk factors such as over-training and rapid increases in workload.

Poor hip control and strength is also a precursor for many other musculoskeletal conditions such as lower back, hip, knee and Achilles pain. So if we could reduce the risk of these outcomes occurring in the future, why wouldn’t we try!

It is possible that MTSS is a condition where the simple treatment of rest is enough to reduce symptoms. Until proven otherwise, relative rest remains the number one treatment option for reducing your symptoms. However, If addressed early, MTSS can be managed with the combination of targeted strength routines, running workloads, manual therapy and ensuring adequate recovery time between training sessions.

Fact or Fiction – Preseason Training

Fact or Fiction – Preseason Training

Answer – FACT

With preseason training just around the corner, this blog is a timely reminder that turning up to preseason training consistently will give athletes the best chance of being able to play most games next year.

Murray et al (2017) reported that AFL players who completed <50% of pre-season training were 2x more likely to sustain in-season injury than those who completed >85%! This is not just relevant to elite AFL, it is relevant to all sports of all levels (even more so)! So what’s the take home message? For the best chance to be able to play week in/week out during the competitive phase of the season, consistency during preseason is vital.

If you had injuries last season or are trying to make this your best season yet, see us to make sure you are ticking all the boxes!

Chronic Groin Pain (Athletic Pubalgia)

Chronic Groin Pain (Athletic Pubalgia)

GROIN PAIN

Groin pain, referred to also as athletic pubalgia, is a common problem for a number of athletes, particularly those who engage in sports that require specific use (or overuse) of lower abdominal muscles and the proximal muscles of the thigh. Predominantly, these activities centre around kicking sports such as AFL and soccer, as well as long distance running. Ice hockey is also a well renowned sport in which chronic groin pain occurs. All these sports involve repetitive energetic kicking, twisting, turning or cutting movements, which are all risk factors for causing pubalgia.

SUMMARY:

  • Four structures are commonly implicated in the causes of groin pain
  • Adductor muscles
  • Pubic bone
  • Abdominal wall
  • Iliopsoas
  • Understanding which of these four structures is causing your pain is key in effective management
  • Exercise therapy and activity modifications should be the mainstay of treatment
  • Absolute rest has been shown to be ineffective
  • Steady gradual progressions through strength and function, tailored to your goals, is key to successful management

ROLE OF HIP ADDUCTORS (groin muscles)

Similar to other joints in the body, the hip relies on muscular control for stability and movement. At the hip, there are five key planes of movement; flexion, extension, abduction, adduction and rotation.

The adductor muscles are a large group of muscles located on the inner side of the thigh, attaching from below the knee, along the shaft of the femur and into the pubic bone of the pelvis.

While acute tears of the adductor muscle is common, more long standing pain is usually the result of an overload of the adductor tendon that attach to the pelvis. This is called an adductor tendinopathy. Adductor enthesopathy is common disorder which effects the bony attachment point of the tendon, with a slight structural difference from tendinopathy, however, management is similar in both cases

MANAGEMENT OPTIONS

Exercise:

Strength and functional based exercise are the core management strategies for adductor tendinopathy, and have been shown to increase function, decrease pain and reduce likelihood of injury [4].

Activity Modification:

Activity modification, especially in the acute phase or when symptoms are significantly affecting function, is key in reducing load on the affected structures and allowing tissues to adapt. [1]

Rest:

While activity modification is important, absolute rest has been shown to be ineffective in the management of adductor tendinopathy, and does not promote adequate tissue repair. [1,2]

Other:

Other conservative measures such as manual therapy, electrotherapy and stretching have been [1] explored, with reduced effect compared exercise prescription. Surgical management is also a potential option, with some positive results emerging for groin pain, though specific evidence [10] around adductor tendinopathy is limited. [10]

WHY IS EXERCISE IMPORTANT?

Exercise has been shown to increase tendon turnover, meaning in the first 24-36 hours there is a reduction in tendon integrity, but after that there is an overall increase in integrity and strength. Other benefits include: increased blood flow, increase in growth factors, and a reduction in altered pain processes in the brain [14].

WHAT’S THE BEST EXERCISE?

Isometric exercise has been shown to be effective in short term pain relief. Current evidence is unclear as to the best long term exercise strategies, with evidence supporting both eccentric and heavy-slow isotonic exercise. [12]

EXERCISE PLAN

The Copenhagen Adductor Program [9], with the below dosage, has been shown to significantly improve adductor strength, as well as being effective in groin injury prevention. It is important to note that though the program is eight weeks long, most effective tendon[12] adaptations take ≥ 12 weeks, and a tailored dosage should be discussed with your physiotherapist towards the end stage of rehabilitation.

Depending on how the symptoms affect your function, a reduction in training, running and kicking may also be required. Example progressions are noted below in the running program, in order of loading on adductors.

ADDITIONAL STRENGTH AND PROGRAMS

While targeted strengthening to the adductors is key, global strengthening around the hip may also aid in a reduction of loading to the tendon. Thorough assessment of your strength through all five movements noted previously is needed, as well as a tailored training program to resolve any discrepancies.

As symptoms reduce and function improves, part practice of painful activities, can be beneficial to reload structures, for example, banded kicking movements in preparation for return to soccer.

SUMMARY

In chronic adductor tendinopathy, tendon adaptations take time. It is important to understand this as you begin your rehab journey and not progress more than your body can tolerate. Steady gradual progressions through strength and function, tailored to your goals, is key to successful management.

Kicking Goals! Praxis looks at AFL kicking mechanics

KICKING

As per usual the Praxis team delved into an area of clinical interest to better understand the demands of our athletes. Last session we discussed throwing technique which you can read about here.

SUMMARY

  • There are differences in kicking techniques when accuracy or distance is the focus.
  • More accurate kickers had tended to be more “head over the ball” with significantly:
  • greater hip flexion in both limbs
  • greater knee flexion in the support limb throughout the kicking movement and greater anterior pelvic tilt at heel contact
  • Longer kick distances were associated with:
  • greater foot speeds and shank angular velocities at ball contact,
  • larger last step lengths, and
  • greater distances from the ground when ball contact occurred.
  • To increase kicking distance:
  • increasing foot speed and shank angular velocity at ball contact, increasing the last step length, and
  • optimising ball position relative to the ground and support foot are recommended.
  • Injuries to the quadriceps are often associated with kicking

Given our longstanding association with AFL clubs around Brisbane, this week we looked at kicking kinematics (joint angles and relationships) with respect to both accurate and long kicks. Further, we discussed how to best rehab someone with a kicking based injury and helping them return to their chosen kicking sport (AFL, Rugby, Soccer, Gridiron etc).

ACCURACY:

The first paper we looked at was from Dichiera and colleagues (2006). Their study involved kicking an AFL football 15m at a target. They found that accurate kickers focussed more on larger hip flexion, anterior tilt and stance leg knee flexion. This best can be described as a “head over the football” approach.

They hypothesise that knee flexion is an important limb length adjustment mechanism which lowers the centre of gravity. During kicking, an increased stance leg knee bend would lower the centre of gravity somewhat throughout the movement. Lowering the centre of gravity is one way of increasing the stability of the body, a principle which is emphasised in many other areas in sports biomechanics.

DISTANCE:

Kicking for distance was associated with greater foot speeds and shank angular velocities at ball contact, larger last step lengths, and greater distances from the ground when ball contact occurred in a study performed by Ball (2008). This was more of a “lean back” strategy utilised by the kickers. Knee angular velocity at ball contact was measured at almost 1400 degrees per second! That kind of speed understandably places the knee extensors (i.e the quadriceps) at greatest risk for kicking injuries.

Ball (2008) outlined some basic coaching instructions to guide those seeking larger distances in their kicks. He suggested:

  • increasing foot speed and shank angular velocity at ball contact by increasing approach speed such that the hip of the kick leg is moving faster towards the target during the last step.
  • increasing the last step length but this step should be proportional to approach speed as over-striding is likely to be detrimental to the kick
  • Optimising ball position relative to the ground and support foot was also recommended though contact too high may result in a high kick, not a long kick.

From a physiotherapy perspective, we discussed:

  • Players have adequate hip extension range as to not to not overload lumbar spine and hip extensors (e.g hamstrings) especially in the presence of larger running and sprinting volumes typical in AFL and soccer
  • Hip flexor strengthening to improve the drive of swing leg through the kick and running
  • How to best reintegrate an athlete who sustained an injury whilst kicking back to full training and competition
  • Preventative exercise such as jump lunges and reverse nordics for quadriceps tissue resilience
  • How lumbopelvic control can help a kicker with both accuracy and distance

In summary, another Brisbane winter’s morning was successfully utilised by the Praxis team. We hope you enjoyed the read! For any injuries that you or your teammates need assessed and sorted fast, contact us.
