Abstract
In order to reduce risk of gonalgia at middle age and iliotibial band syndrome, i.e. IT band syndrome, which is called as runner's knee, biomechanics movement of knee at running and jogging is key point. Too big fluctuation in the perpendicular to the running direction might be a source of gonalgia. When a runner can recognize proper movement at running by himself, the risk of runner's knee might be reduced. In the present paper, in order to recognize the proper movement of knee, an evaluation method of the fluctuation of knee was proposed. The movement of knee was evaluated by detecting difference between knee and thigh using a high speed video camera and pattern recognition of image processing. In order to investigate a possibility of reducing method by sole insert, the fluctuation of the knee was measured changing with shoe and sole insert. It was concluded that the fluctuation of the knee could be measured by a high speed video camera and image processing.
