FACT OR FICTION: Is running bad for your knees

FACT OR FICTION: Is running bad for your knees

by | Aug 3, 2019 | Gym and Strength, Knee, Osteoarthritis, Pain, Running Injuries

We at Praxis think that patient education is the cornerstone of good physiotherapy. We particularly enjoy discussing people’s understanding of their injuries or the beliefs around certain activities. As such we are starting “Fact or Fiction Friday’s” in which we tackle some misconceptions that may negatively affect people’s rehab or willingness to participate. To get us off and running (love a pun) let’s start with:

QUESTION: Recreational running will wear out your knees (quicker than not running)

ANSWER: FICTION

Running appears not to increase risk of osteoarthritis in knees unless you are a competitive long distance runner. Even then, you are only slightly above the average for non-runners but enjoy the myriad of other benefits that exercise brings.

Check out our previous post on this here. If you are a runner or have knee pain, book in with us so we can assess you and get you back to what you love doing. Call (07) 3102 3337 or book online

Pilates: Reforming our back pain rehabilitation (Part 1 of 3)

Pilates: Reforming our back pain rehabilitation (Part 1 of 3)

by | Jun 3, 2019 | Lower Back, Pain, Reformer Pilates

With our 30 day pilates challenge starting today, we thought we would take a look at why we love pilates so much for our patients, and what some of the benefits are. Part 1 looks at how pilates affect those with chronic lower back pain. Part 2 looks at the difference between mat and reformer pilates and part 3 looks at how often is required to see the benefit of pilates.

SUMMARY:

  • Back pain is extremely common, multifactorial, and often reoccurs
  • Strengthening interventions appear better for long term suffers of lower back pain
  • Pilates has been shown to improve muscular strength and endurance of key pelvic and postural musculature associated with lower back pain
  • Specifically, pilates promotes the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles
  • As little as 2 sessions per week for 6 weeks has been shown to see improvements in pain and function for those with longstanding lower back pain, even after stopping pilates

Chronic low back pain (CLBP) is one of the commonest musculoskeletal problems in modern society (Anderson 1999) and is a highly prevalent in both the sporting and general public. CLBP is experienced by 70%–80% of adults at some time in their lives (Crombez et al 1999) and as such, the costs associated with LBP and related disability are enormous, causing a major economic burden for patients, governments and health insurance companies (Dagenais 2008).

Lower back pain has been one of the most extensively studied musculoskeletal conditions as a result of the prevalence and debilitation nature. Its management comprises a range of different intervention strategies including surgery, drug therapy and non-medical intervention like rehabilitation (Paolucci et al 2018). Within Physiotherapy, exercise therapy is probably the most commonly used intervention for the treatment of patients with chronic non-specific LBP due to its plausible biological rationale and low cost.

Whilst general conditioning programs to train strength and endurance of the spine musculature have been shown to reduce pain intensity and disability (Rainville et al 2004), the popularity of pilates (both mat and reformer) has helped provide an accessible and supervised form of therapeutic exercise.

EVIDENCE FOR PILATES

The Pilates method, using functional exercises aims to improve muscular strength and endurance. Specifically, the pilates method have promotes the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles. Using the principles of progressive overload, your body adapts to the incremental loading week after week and consequently results important postural control improvement. In 2009, Curnow and colleagues showed that the Pilates method improves load transfer through the pelvis, something that intuitively helps those with CLBP.

However, a systematic review (Patti et al 2015) reported evidence that Pilates method-based exercises are more effective than no treatment or minimal physical exercise interventions in the management of chronic nonspecific LBP. Further, they pointed out that the effects of the Pilates method are only proven for patients with chronic nonspecific LBP in the short term.

A recent study by Natour and colleagues (2015) showed that the group of participants that were practicing Pilates method resulted statistically better compared with the a non exercising group who only used inflammatory medication. Those who were in the pilates group used less pain medication at 45, 90 (conclusion of the Pilates method), and 180 days, 90 days after the conclusion of the exercise program.

In conclusion, Pilates as an exercise choice is more effective than minimal physical exercise or drug based interventions in reducing pain and disability in the short-term period. There is agreement that exercise “helps” in the treatment of chronic pain, but it is still not clear exactly which factors or particular kind of exercises may be responsible of such improvements (Natour et al 2015; Patti et al 2015). Praxis Physiotherapy has always been a strong proponent of movement and loading early in rehabilitation (more on this in later blogs!).

In the next instalment, we discuss the difference between mat and reformer pilates and perhaps find some more answers regarding which exercise regime reigns supreme!

Is running bad for your knees?

Is running bad for your knees?

by | Nov 28, 2018 | Knee, Pain, Return to Sport, Running Injuries, Sports Injury

Running. Probably one of the most maligned exercises when it comes to knees and overuse injuries. The thought that running ‘wears’ out your knees and causes osteoarthritis (a chronic disease often associated with joint pain and stiffness, reduced mobility and reduced quality of life) is one of the most common comments I hear as a physiotherapist – typically by non-runners. But do we have it right? Is running actually bad for your knees?

I recently attended the University of Queensland Sports Masters presentation day. The keynote speaker was a Dr Jean-Francois Esculier, a Postdoctoral Fellow at the University of British Columbia on the topics of running and knee osteoarthritis. Originally trained as a physiotherapist, Dr Esculier gave us an excellent overview of his latest research his take on whether or not running is detrimental to knee health.

First, there was an acknowledgement that echoed the sentiments in the opening paragraph. A study in which Dr Esculier undertook attempted to ascertain the perception about running and the knee joint health among the public and health care professionals. The results suggested that many non-runners perceived running as detrimental to knee health. Understandably, with no clear guidelines, health care professionals displayed high rates of uncertainty regarding running as a risk factor to develop knee osteoarthritis (KOA), and about the appropriateness of running with pre-existing KOA [1].

Mid Potion Achilles Tendinopathy Location

Osteoarthritis often results in cartilage loss, in bone rubbing on bone, which can cause inflammation, pain, stiffness, reduced mobility and reduced quality of life [7].

The paucity of clear training parameters for runners also has a knock on effect with a staggering 75% of runners report being injured whilst running each year with the knee being the most common region of complaint [2]. From my experience as a clinician, the factor that is most often associated with an injury are training errors. Too much too quick. Boom bust. No physical preparation. No listening to your body or allowing adequate recovery time. No periodisation or plan – just run and run.

The remainder of the talk that covered many interesting relatable topics (that will likely be areas for future blogs) but the information that most interested me and should answer the question as to whether running is bad for your knees was the following:

Cartilage change with running:

With the improvements in MRI scanning, more papers are looking at the cartilage volume of knees immediately after a long distance run. According to current evidence [3], cartilage may exhibit short-term decreases in thickness, volume and cartilage water flow (T2 relaxation time) secondary to temporary loss of fluid following repeated compressions associated with running. However, cartilage size tends to return to baseline within hours suggesting that cartilage may well tolerate mechanical loading sustained during running and adapt to repeated exposure.

The response of cartilage to longitudinal load is exactly what Van Ginckel et al [4] investigated. After providing a 10 week “Start To Run” program to novice runners, the reserachers looked at the glycosaminoglycan (GAG) content before and after the running intervention and compared to sedentary controls, who did no running. For those of you (like me) who had no idea what glycosaminoglycan / GAG content is, it is essentially a surrogate marker for cartilage quality (specifically, GAG is an important structural matrix compound in regulating the cartilage tissue’s endosmotic swelling pressure and thus, the tissue’s compressive strength).

The results suggested that a gradually built up running scheme appears to positively effect GAG content, and thus cartilage quality. In fact, running appears to be a chondroprotective effect on the knee when compared to a sedentary lifestyle in a female asymptomatic subjects. The author’s went onto say that running schemes like this might be considered a valuable tool in osteoarthritis prevention strategies [4].

Osteoarthritis (OA) rates in competitive vs recreational vs non-runners:

The body’s ability to adapt to considered and appropriate load is likely explanation as to why when we look at the rates of lower limb osteoarthritis (OA) across the population, we find some interesting results. A systematic review [5] of the literature looked at the association of recreational and competitive running with hip and knee OA. The overall prevalence of hip and knee OA was 13.3% in competitive runners, 3.5% in recreational runners, and 10.2% in controls. Exposure to running of less than 15 years was associated with a lower association with hip and/or knee OA compared with non-runners.

Recreational runners had a lower occurrence of OA compared with competitive runners and controls. These results indicated that a more sedentary lifestyle or long exposure to high-volume and/or high-intensity running are both associated with hip and/or knee OA. However, it was not possible to determine whether these associations were causative or confounded by other risk factors, such as previous injury [5].

SUMMARY

Running appears not to cause osteoarthritis in your knees unless you are a competitive long distance runner. Even then, you are only slightly above the average for non-runners but enjoy the myriad of other benefits that exercise brings. Further, increased mileage in recreational runners appears to be actually protective for your knees and reduces your risk of needing a knee replacement [6]. Caution however must be taken to monitor detailed training parameters such as frequency, speed and distance, so that an optimal dosage for knee joint health tailored to the individual patients with knee osteoarthritis.

So the next time someone tells you that you shouldn’t be running because you’ll get OA, or if your health expert recommends to stop all activity because you have been diagnosed with mild / moderate osteoarthritis of the knee, we can help!
