Having had a slight niggle in my right knee for some time now, it has finely dawned on me that this was an worse injury in the making. After several visits to the physio with no luck and several pounds lighter(GB pounds that is). It was off to the the bio-mechanics specialist for an gait assesment. There is a local specialist in nearby Wakefield who specialises in running injuries and the like. Having spent the first few visits just talking about the mechanics of running and how certain injuries can develop and progress-I did initially feel that I was wasting my money.
The problem is my left leg is slightly shorter than my right leg, thus striking the ground first, leading to extra pressure and forces on my right leg and knee. Oddly, (something I have just learnt), we are all asymetrical(not having equal sides). The body can compensate for this and usually it isn't a problem, but when your running a large amount of miles it can create stresses which can lead to injuries.
Pronation is the natural inward rotation of the foot to prevent injuries to the ankle and other joints further up to the legs and even the back. In my case pronation is too excessive and if it is not controlled may lead to other injuries. He thinks this may be partly responsible for the slight knee pain. You can get shoes which control motion(motion control shoes), but these are not precise and will not always work to control the pronation, because eventually the muscles which are controlling pronation will overtake.
A cast was taken of both feet and I was to call back two weeks later for the finished othotics. These are made of hard plastic type material, with a softer rubber type covering them. I will keep you informed of the results in due course.
