No muscle in our body works in isolation, our muscles are designed to work in pairs to produce movement. In elite sport there is strong evidence to show that in joints where one muscle is too strong or too weak (either comparatively with its partner muscle or relative to your body weight) then the joint or muscle can become painful, recovery from injury can be delayed and risk of future injury can significantly increase.
There are many ways to assess muscle strength but one of the quickest, easiest and most useful in clinic is with a hand held dynamometer.
Recent research with in the Australian Swimming team by Boettcher (2013) supports the use of dynometers in functional mobility testing of their swimmers. Testing found that the best ratio for rotation shoulder to minimise pain was 1:1.46 [+/- 0.17] (external:internal). Having this data greatly enhances a team therapist's ability to support optimal performance by establishing a baseline for an athlete's "normal" muscle and joint functionality.
Through years of experience with elite sporting teams, North Curl Curl Physiotherapists have developed the expertise to apply this technology to our patients.
