THE IMPORTANCE OF MUSCULOSKELETAL SCREENING

Finals time for most winter sports is fast approaching and from a physiotherapy perspective this is the time of year that we see a spike in sporting injuries. A lot of these injuries tend to be to parts of the body that have some sort of deficit, be it strength, length or control. It is quite hard to be able to identify these areas yourself and even physiotherapists would find it hard to accurate identify these deficits purely through observation.

This is why screening is so widely utilised for athletes from amateur to elite. Screening usually involves a battery of tests that give objective measurements that are then compared to the normal values for an athlete in a specific sport. Screening can also involve questionnaires that focus on general health and previous injury history.

An article by Sanders, Blackburn and Boucher (2013), looked at the use of pre-participation physicals (PPE) for athletic participation. They found PPE’s to be useful, comprehensive and cost effective. They explained that PPE’s can be modified to meet the major objectives of identification of athletes at risk.

An article by Maffey and Emery (2006) looked at the ability of pre-participation examinations to contribute to identifying risk factors for injury. They found limited evidence for examinations in terms of the ability to reduce injury rates among athletes. However, they were effective in the identification of previous injury (such as ankle sprains) and providing appropriate prevention strategies (such as balance training). From this it has been shown to reduce the risk of recurrent injury. It may also be useful in identifying known risk factors which can be addressed by specific injury prevention interventions.

An example of a screening measure that is typically used in screening protocols includes a knee to wall test (KTW). This test is used for ankle dorsiflexion as well as soleus muscle length (one of your calf muscles). The test is performed using a ruler which is placed perpendicular to a wall with no skirting board. The athlete puts their foot flat on the ground next to the ruler and as far from the wall as possible as long as their knee is touching the wall. Distance from the wall to the end of the big toe is noted by looking at the ruler. An example of a normal distance for netball players is greater than 15cm on each side.

Here at East Vic Park Physiotherapy we have developed a number of specific musculoskeletal screens for a variety of sports including netball, running, swimming and throwing sports. They comprehensively identify the key risk factors that are seen in injuries sustained in each sport.

Low Back Pain

Approximately 80% of people will experience lower back pain at some stage in their life. It is one of the most common reasons for people missing work and seeing a doctor or physiotherapist. Although it is extremely common it can often a bit of an unknown to the general public as to what is the cause for their pain and disability.

There are many different causes of low back pain from strains/sprains, posture related pain and overuse injuries. This blog post will mainly focus on acute strains or sprains of the low back.

Similar to other joints around the body, strains or sprains to the low back occur when a stress is placed on a tissue that exceeds what it is capable of handling. An example of this could be someone bending over to lift a heavy object off the floor. However, a heavy force is not always required to strain the back. Repetitive movements of small force can also do this. 

Again like other joints around the body, different structures around that area can be irritated or strained. For the low back this can be surrounding muscles, ligaments, facet joints, discs or a combination of a few structures.

Timeframes of recovery will vary depending on what structures are involved, the severity of the injury, the demand of the person and lifestyle factors such as sleep, stress levels, diet ect.

What Can I do?

The back responds very well to movement. It is encouraged to continue to keep moving within your pain limitations.  Identify positions and movements your back feels better with adopt these positions rather than the painful ones.  This will differ from person to person so your physiotherapist will go over these particular activities/positions with you.

What can’t I do?

Your pain and symptoms will often be exacerbated immediately during specific activities. However, an increase in symptoms can often be noticed after completing particular tasks or even the following morning/day.

It is important to identify these activities or postures and avoid over repetition of them or prolonged time spent in those positions.  These activities are often simple tasks we complete on a regular basis throughout the day so it is often unrealistic to completely avoid them. Instead, modifying how we complete them or limiting how much of them we do of them will be more effective. Eg sitting posture or length of time spent sitting.

Do I need a scan?

The majority of back injuries do not require any scans or imagining and will resolve without the need for a scan. Scans can also be misleading at times as they tend to show everything that is happening in your back even when it’s not the source of your pain. Scan results can make people anxious, worried and stressed which can make their pain significantly worse.

 Imaging of the low back is potentially required when treatment/management of the injury could potentially change depending on the diagnosis or extent of the injury.  Your GP or physiotherapist will discuss with you if they think imaging is required in your case.

Do I need surgery?

Again, like imaging most low back injuries do not require surgery. However, there are circumstances where surgery may be required or beneficial in addressing certain injuries.  Obviously there are risks when any surgery is performed and so they are only recommended when they are truly needed.

When can I return to exercise?

This is a difficult question to answer as it will depend on a number of factors including the type of exercise you are attempting to return back to, the severity of the injury and previous injury history. However, in general, most soft tissue injuries have a recovery timeline of about 4-6 weeks. There will often still be things you will be able to do during your rehabilitation. This will usually start off with activities that do not exacerbate symptoms followed by modified versions of more complicated tasks with the aim to progress back to your previous level of function.  

Will this injury reoccur?

Like most injuries there is always a risk it re-aggravating Your treating physiotherapist will advise you on ways to best prevent this from happening. This will often involve an exercise program to address any deficiencies and optimising technique and posture with specific tasks/activities.
