This post is to highlight and relieve concerns over Carpal Tunnel Syndrome (CTS ) There are many mis-understood things about CTS, and as one of the more frequent topics raised here on TB there seems to be many misconceptions about it....so here is a simple definitive guide to what we know and understand and what options are available to treat it....and help prevent it. Overview. We cannot stop or prevent CTS as such, because it is an anatomical problem related to life and our use of the hands based on the mechanics of hand design,( for the use of a better word), and the growing uses we now use them for in a modern world for work and leisure. Our hands evolved their use over thousands apon thousands of years, the last twenty years has seen that use explode, and as such evolution cannot catch up to refine the hands to account for it and never will. The golden rule is " mis-use and over use are the main source of problems" so identify your own areas that may present or promote problems and deal with them accordingly. Muscles only pull, the work in opposite pairs, as one shortens the opposite one lengthens. So in your hands when you close your fingers they are pulled closed, when you open them they are pulled open. This means that the two opposite muscle groups work together, when one shortens as in to pull the finger in, the other side must lengthen to allow it, they must also both create "a muscle tension" between the two to find and hold the correct position for the finger use. This is where problems occur because in playing only one set of muscles really gets targeted in small limited motion, as we always hear and read about "economy of motion". This means a constant muscle tension is used so the hand is never relaxed as such. This is why warming up and stretches pay big dividends, they re-introduce a full range of motion again and help remove un - wanted or un-used muscle tension.....again muscle tension is needed for movement, what we do not need is un-necessary muscle tension....after all with out muscle tension in your body for example, you would not stand up, you would just fall over. But sleep and rest relieve and help remove that tension....as does exercise and stretching when awake. So what is CTS? The link below explains it in simple detail better than words alone.
