Sydney is in lockdown again from Friday June 25th to Friday July 9th.
During this current lockdown, Fit As A Physio is staying open to continue offering quality care to my clients.
The Department of Health has specifically confirmed that physiotherapy is deemed an essential service. The Health Minister has encouraged private practices to remain open, as it will reduce demand on general practice and the hospitals if patients can still see their physiotherapist for their musculoskeletal and acute care management.
I have completed the Department of Health's "COVID-19 Infection Control Training". I have reviewed all clinic hygiene practices, to ensure optimal safety and care for every person who attends the clinic.
There are many things I am doing as a registered health professional to minimise risk of exposure, through rigorous hygiene practices, and patient screening, to keep you safe.
You are welcome to attend your appointment, subject to the following conditions:
Thank you for your cooperation with these measures.

Sports and exercise medicine clinicians often refer for diagnostic imaging to help direct clinical management. The use of musculoskeletal MRI has risen rapidly in recent decades, yet the clinical benefit of MRI is uncertain. Imaging is useful for the differential diagnosis of many health conditions, including possible red flags, however, there are growing concerns of potential harm from MRIs caused by clinicians misinterpreting results triggering unnecessary interventions escalating patient fear/distress. Evidence-based reporting and clinically relevant interpretation of MRIs is critical.
Recognising the clinical significance of MRI findings is often a challenge given the substantial discordance that exists between structural pathology and symptoms. Emerging evidence indicates a high prevalence of so-called abnormal findings on MRI in individuals without symptoms. A collation of systematic reviews (and cohort studies when no review available) highlights that typical features of deterioration, such as cartilage lesions, hip and shoulder labral tears and spinal changes (eg, disc degeneration/bulge) exist in many healthy asymptomatic adults (figure 1). Approximately 8 of 10 adults aged ≥40 years have asymptomatic disc degeneration, while almost half of all adults aged ≥40 years have knee cartilage lesions but no pain. Although the prognosis of these asymptomatic findings is not well established, even in cases of further structural deterioration (eg, longitudinal cartilage loss) the association with pain appears minimal.5 These findings are critical for clinicians and patients to understand the relevance of structural pathology and can be used to address recent calls for radiology reports to include age-matched asymptomatic prevalence rates. Such an approach, together with discussion with patients putting MRI findings into context, may help minimise patient anxiety, and beliefs they are damaged and vulnerable, as a result of a diagnostic label. Including such epidemiological information on spinal MRI reports reduced subsequent opioid prescription although had little effect on healthcare utilisation.
The high prevalence of asymptomatic changes on MRI emphasises that such features may not always be the source of pain in symptomatic patients and should not routinely be considered as pathological processes requiring intervention. Instead, in many people they likely represent part of the normal ageing process—like wrinkles on the skin.
Current evidence suggests that it is more common than not to have a cartilage lesion or disc bulge as we age. Perhaps it is time we redefine what a ‘normal’ MRI is and start being ‘CLEAR’ with patients when discussing imaging results—consistent language, including epidemiological information and assessment of relevance.
The two most important factors for successfully rehabbing a hamstring strain, are:
(Other factors include: stretching, massage, rolling, ice, compression, tape, sleep, stress, maintaining cardio, skills, general strength.)
Three exercises to start from day 1, are:
ACTIVE KNEE EXTENSION
Hold and stabilise the thigh of the injured leg with the hip flexed approximately 90° and then perform slow knee extensions to a point just before pain is felt. Three times a day, three sets of 12 repetitions.
SINGLE LEG ROMANIANS / ARABESQUE
Hip flexion (from an upright trunk position) of the injured, standing leg and simultaneous stretching of the arms forward and attempting maximal hip extension of the lifted leg while keeping the pelvis horizontal; angles at the knee should be maintained at 10–20° in the standing leg and at 90° in the lifted leg. Owing to its complexity, this exercise should be performed very slowly in the beginning. Three times a day, three sets of 10 repetitions.
This exercise is started in a supine position with the body weight on both heels and then the pelvis is lifted up and down slowly. Start with the knee in 90° of flexion. The load is increased by putting more of the body weight on the injured leg and by having a greater extension in the knee. Ultimately, only the slightly bent injured leg is carrying the load. Three times per day, 3 sets of 10 repetitions.
IS IT BAD TO HAVE "STIFF" MUSCLES?
Stiff muscles are a counterintuitive superpower of NBA athletesPhilip Anloague, University of Dayton
For most people, the term “stiffness” has negative connotations. When you wake up in the morning complaining of a “stiff back,” the remedy might include taking a hot shower, doing some yoga, swallowing aspirin, or visiting a physical therapist to loosen up. Stiffness is typically viewed as unpleasant and can limit one’s physical activities.
Surprisingly, though, for elite athletes like professional basketball players, muscle stiffness is not only something that is necessary, you could say it’s their superpower. As a physical therapist and researcher who works with National Basketball Association players, I’m interested in understanding the key factors that help to minimize injury risk and maximize performance in elite athletes – and understanding stiffness is an important part of that.
Spring in your step
Physiologists think of muscles as being like biomechanical springs. Muscles contract to produce forces that help you move and stretch to allow enough range of movement. Stiffness is a way to talk about how springy a muscle is. It is a characteristic of how much it can lengthen in response to an applied force. The spring of a muscle allows it not only to stretch but also to recoil during muscle contraction. This process allows for movements including walking, running and jumping.
The force required to deform or stretch a muscle is correlated to a degree of spring or stiffness and to the extent the muscle is lengthened. Strength is important, but stiffness can help an athlete generate even more power.
Basketball is a vertical sport that includes up to 46 jumping and landing activities for an individual player per game. That’s 2 to 4 times more jumping than in soccer or volleyball. It’s also a multi-directional sport – an average player changes direction or activity every 2 to 3 seconds, requiring constant acceleration and deceleration of movements.
Lower extremity stiffness is important for optimal basketball performance because athletes who appropriately use greater stiffness characteristics can take advantage of the elastic energy it creates. A muscle can only stretch so far because its length is limited by its degree of stiffness. So, like a spring or a rubber band, when the muscle is stretched, that stiffness helps to create elastic energy that can then be used with a muscle contraction to help you run or jump on the court.
This helps someone like Russell Westbrook leap in the air, stop on a dime, then accelerate down court during a fast break. It takes him just 3.36 seconds to run from baseline to baseline.
The sweet spot
However, there is a point of diminishing returns. Too much muscle stiffness can lead to reduced joint motion and a decreased ability to absorb shock at the joints. This can place one at greater risk for stress fractures or even osteoarthritis, the wear and tear of cartilage that can cause joint pain. Evidence suggests that too much stiffness may lead to injury.
And on the other side of the spectrum, a player needs a certain degree of flexibility and joint mobility to support the proper elongation of muscle and tendons that allow for the appropriate range of motion.
So players need to balance these extremes, landing in the sweet spot of optimal lower extremity stiffness: not too much, which can lead to high levels of force and loading rates and a greater risk for bony injuries. And not too little, which is associated with an increased risk for soft tissue injury and muscle strains.
My research team is investigating these relationships in an attempt to help elite athletes minimize risk of injury and maximize performance. The first step is in understanding what “normal” clinical measurements are for elite athletes.
Textbook values have been established for the general population but this information is lacking for NBA players. For example, a typical value of ankle flexibility for the average individual is about 50 to 55 degrees. Our research team has found that the typical NBA player is more stiff and averages 35 degrees.
When comparing elite basketball players to textbook norms it might appear that they are too tight and even dysfunctional. However, to be successful in their sport, this degree of stiffness is actually their superpower. If trainers start stretching Lebron James’ muscles to match the textbook values of the general population, he may start jumping like the general population. That tactic could very well be kryptonite to an NBA athlete.
Training to minimize injury and maximize performance
Physical therapists know that the so-called fast twitch muscle fibers – the ones responsible for jumping and sprinting – have a higher propensity for stiffness. With training the level of stiffness can be increased to improve performance.
Evidence suggests that plyometric and bounding exercises that involve jumps, hops, or bounds, performed in a stretch shortened cycle do have a positive effect in the ability for muscle to have more spring. But overall, your own degree of stiffness versus springiness is a combination of nature and nurture, genetics and training.
Research related to better understanding the continuum between stiffness and compliance can help physical therapists and trainers when working with basketball players. They need to know dosage – how much to stretch or strengthen. Work is underway that contributes to this endeavor. There are also initiatives that aim to understand player load and the cumulative physical demands that elite athletes undergo when generating fast and powerful movements. Researchers also need to understand what the best methods and technologies are for monitoring these loads. My colleagues and I theorize that there is an optimal level of compliance and stiffness that helps keep our basketball heroes super.
"Including the Nordic hamstring exercise in injury prevention programmes halves the rate of hamstring injuries: a systematic review and meta-analysis of 8459 athletes."
(Nicol van Dyk, Fearghal P Behan, Rod Whiteley, British Journal of Sports Medicine. Published Online First: 26 February 2019. doi: 10.1136/bjsports-2018-100045)
Research question Does the Nordic hamstring exercise (NHE) prevent hamstring injuries when included as part of an injury prevention intervention?
Design Systematic review and meta-analysis.
Eligibility criteria for selecting studies We considered the population to be any athletes participating in any sporting activity, the intervention to be the NHE, the comparison to be usual training or other prevention programmes, which did not include the NHE, and the outcome to be the incidence or rate of hamstring injuries.
Analysis The effect of including the NHE in injury prevention programmes compared with controls on hamstring injuries was assessed in 15 studies that reported the incidence across different sports and age groups in both women and men.
Results There is a reduction in the overall injury risk ratio of 0.49 (95% CI 0.32 to 0.74, p=0.0008) in favour of programmes including the NHE. Secondary analyses when pooling the eight randomised control studies demonstrated a small increase in the overall injury risk ratio 0.52 (95% CI 0.32 to 0.85, p=0.0008), still in favour of the NHE. Additionally, when studies with a high risk of bias were removed (n=8), there is an increase of 0.06 in the risk ratio to 0.55 (95% CI 0.34 to 0.89, p=0.006).
CONCLUSIONS: Programmes that include the NHE reduce hamstring injuries by up to 51%. The NHE essentially halves the rate of hamstring injuries across multiple sports in different athletes.
INJURY PREVENTION IS IMPORTANT FOR RESULTS
Success in sport is dependent on a number of factors (eg, skill, fitness, squad size, tactics, and psychological factors). Athlete durability is also a key component of success.
In team sports, research shows a strong link between player availability and the success of the team, and that injuries and illness are the most common reasons for athlete unavailability in training and matches (REF). Research in team sports demonstrates an inverse relationship between injury burden and success of the team. Lower player availability is associated with failure to achieve key performance indicators. Injuries detrimentally affect the final ranking position in team sports (REF). And, research from professional European football shows lower season injury rates results in more successful seasons (REF).
Injuries and illnesses also affect success in individual sports. In elite track and field athletics, injuries and illness and their influence on training availability during preparation are major determinants of an athlete's chance of performance goal success or failure. Research shows the likelihood of achieving a performance goal increases by 7-times in athletes who complete >80% of planned training weeks. And, training availability accounts for 86% of successful seasons (REF).
So, injuries can determine success of failure in team and individual sports. Therefore, injury prevention strategies should be a focus for success-driven athletes and teams.
INJURY PREVENTION PROGRAMS
A number of sporting bodies have developed standardised injury prevention programs that are very effective at reducing injury rates. Sports that include these programs into their training have been shown to have between 50-80 per cent fewer injuries. These injury prevention programs are a series of exercises that are reasonably quick and easy to perform as part of a warm up. They include plyometric (jumping and landing), neuromuscular control (challenging balance, agility, addressing poor movement patterns), and strength exercises.
For every 1,000 hours of game play, elite football players suffer between 12 – 35 injuries (REF). The most common types of injury sustained during a football game are muscle strains, ligament sprains, and contusions. Ankle, knee, and groin have the highest incidence of injury, and the greatest risk for sustaining an injury is during a football game as opposed to during a training session (REF).
The warm-up program “FIFA11+” is an injury prevention program designed by the Federation Internationale Football Association (FIFA) Medical and Research Centre (F-MARC) in 2006. It was designed to reduce the occurrence of injuries associated with playing football.
The FIFA11+ consists of three parts and 15 exercises in total:
The FIFA11+ program has been studied extensively over the last ten years to determine its effectiveness on injury prevention and physical performance measures, across a variety of populations. The FIFA11+ program has been shown to significantly reduce the risk of injuries in football (REF). This includes a 77% decrease in ACL injuries (REF), a 48% reduction in lower limb injuries (REF), and an overall injury reduction of 35% per 1000 hours (REF).
FIFA 11+ and more resources for injury prevention in football are available here: footballnsw.com.au/protection-and-safety/injury-prevention/
Netball Australia has developed the "KNEE Program” to help prevent knee and other lower limb injuries in netball.
Knee and ankle injuries are common in netball, making up three quarters of all injuries. Devastating ACL injuries are unfortunately common in netball, making up 25% of the serious injuries.
The KNEE program offers a range of warm-up exercises that help prevent injury. There are a range of age and experience appropriate exercises for junior, through to elite netballers. They are easily understood by players and coaches, with a number of options offering variability and progression.
It would be great for the KNEE program to be widely adopted by Australia's largest participation sport for females.
KNEE Program resources are available at: https://knee.netball.com.au
AUSTRALIAN RULES FOOTBALL
FootyFirst is a five level progressive exercise training program that has been developed specifically to reduce the risk of common leg injuries in community Australian rules football.
FootyFirst begins with a warm-up, followed by leg strengthening and conditioning exercises, and training to improve balance, landing and side-stepping skills. It requires only standard training equipment and can replace the traditional warm-up. Once players and coaches are familiar with the exercises, the warm-up should take about 5 minutes, and the strength and conditioning exercises and jumping, landing and changing direction activities about 15 minutes.
Performed correctly and frequently, FootyFirst will improve performance and reduce injury risk. FootyFirst has been shown to decrease knee injuries by 50% and all leg injuries by 22% (REF). It will improve players’ leg strength and control – from their hip to hamstring, groin to thigh, lower leg, knee, ankle and foot.
Resources include the FootyFirst Coaches’ Manual, a series of posters illustrating the exercises at each level, and the FootyFirst Coaches DVD is available at: aflcommunityclub.com.au/index.php?id=906
THE PROBLEM WITH SCREEN TIME
Around 30% of patients I treat have a complaint that is caused by prolonged sitting, commonly in front of a screen. This is mostly neck and back pain caused by things like; getting stuck at the desk too long, long commutes, long-haul flights, binge watching Netflix on the lounge, or looking at the iPad in bed.
This is a relatively new activity for humans and we're just not used to it. From an evolutionary point of view, we're just not adapted to sitting still all day. We've had 100,000 generations of hunting and gathering, moving around, doing different things all day. We've had 50 generations of agriculture, and only 10 generations of industry, where we're expected to sit and do the same repetitive task for prolonged periods of time. We're just not used to staying still from 9-5. Our bodies have evolved to move and be used. Staying still makes us sore.
NOW, WORSE THAN EVER
COVID-19 has caused a unique moment in time, with unprecedented social and workplace disruption. Never before have so many people been required to work from home. People are working at the dining table or kitchen bench. People are on their laptops on the lounge or in bed. The home set-up isn't ideal.
Also, some of the usual workplace activities that might get you away from the screen, like getting into the boardroom for a meeting, are now happening online too, so there are less reasons to get up and move away from what you're doing.
My workload has decreased with people self-isolating, but every new patient I've had in the last two weeks has been someone with neck pain or back pain caused by working from home.
So remember, if you're getting a sore neck, or a pain next to your shoulder blade, get up and more around more. It's time to take a break.
If you're getting a sore back, or an ache into the top of your buttock, get up and move around more. It's time to take a break.
It should be very simple. Motion is lotion. Rest is rust.

PT Inquest, my favourite physio podcast, recently discussed this paper:
Misconceptions and the Acceptance of Evidence-based Nonsurgical Interventions for Knee Osteoarthritis. A Qualitative Study
The abstract summarises:
In contrast to best practice guidelines for knee osteoarthritis (OA), findings from several different healthcare settings have identified that nonsurgical treatments are underused and Total Knee Replacement surgery is overused. Empirical evidence and qualitative observations suggest that patients’ willingness to accept nonsurgical interventions for knee OA is low.
Participants’ beliefs about knee OA and its treatment were identified. Beliefs were grouped into five belief dimensions:
The participants' beliefs are what I would guess, based on what I hear from patients everyday:
The authors conclude:
Common misconceptions about knee OA appear to influence patients’ acceptance of nonsurgical, evidence-based treatments such as exercise and weight loss.
Once the participants in this study had been “diagnosed” with “bone-on-bone” changes, many disregarded exercise-based interventions which they believed would damage their joint, in favor of alternative and experimental treatments, which they believed would regenerate lost knee cartilage.
These misconceptions do feel like commonsense and, as such, are widely held by the general public. Some of them may be true at the very end stage of osteoarthritic disease, but they are definitely not true for all patients with osteoarthritis, and as such, the misconceptions are harmful because patients disregard beneficial conservative treatments like weight loss and exercise, and rush towards surgical options.
"BONE ON BONE" is a metaphor that is commonly used, even by physios and knee surgeons.
"Bone on bone" creates a very dramatic image of what's going on in the knee, and undermines the possibility of osteoarthritis being pain free. Using words like "bone on bone" can cause harm because it sounds like it is definitive and painful, when in reality it's only a metaphor.
The reality could be explained more like: "the joint reinforces and repairs the damaged area by laying down new tissue". Or, "the joint wants to make itself even stronger than cartilage, so it lays down stronger building blocks - bone cells".
Not everyone with osteoarthritis has "bone on bone", and the perception of "bone on bone" as what's happening in the knee can make patients less likely to stick with evidence-based conservative treatment options.
The concept of "WEAR AND TEAR" makes sense if you imagine the joint as mechanical. A cupboard's metal hinge can be opened and closed a certain number of cycles before it breaks. Metal and plastic fatigues and fails. Mechanical joints "wear out". But our joints aren't made of metal and plastic. Knees are not mechanical joints. They are biologically active joints, that adapt to what we do.
If we do a million bicep curls, we don't expect our biceps to "wear out" - we expect to end up with bigger, stronger biceps. Similarly, the bones, cartilage, ligaments and muscles in our knees are biologically adaptive, they have regenerative ability, and adapt to what we do. Our joints get stronger with use.
Rather than "wear and tear", the more appropriate phrase should be: "use it or lose it".
DOESN'T RUNNING "WEAR OUT" KNEES?
Another common misconception is that running "wears out" knees.
Doctors and knee surgeons see patients complaining they have sore knees when they run. The X-ray shows some arthritis, so it's very easy to make the assumption that running causes arthritis. But we know that distance runners don't "wear out" their knees. Runners have better knees than non-runners.
This 2017 research comparing 2,637 runners to non-runners (matched for age, weight, mileage, injury, and other variables) concludes: There is no increased risk of symptomatic knee OA among runners compared with non-runners. In those without OA, running is not detrimental to the knees.
This 2008 research concludes: Long-distance running among healthy older individuals was not associated with accelerated radiographic OA, and long-distance running or other routine vigorous activities should not be discouraged among healthy older adults out of concern for progression of knee OA.
This 2004 research concludes: The results of this literature review strongly suggest that regular mild-moderate impact exercise does not increase the risk of OA, and that there is some evidence that it does not increase symptoms in patients with mild-moderate OA. And: Regular running increases joint space width.
