Abstract
In rural areas of developing countries, ankle foot orthoses that can be manufactured at low cost are required. Also, systems that can be set up with readily available, low-cost materials which can easily measure their effectiveness are also required. In this paper, I report on, a low cost motion analysis system that can easily measure the effectiveness of orthoses was developed in China. In this system, a home digital video camera was used for video recording for analysis, aluminum foil for a foot switch, and freeware for analysis software. Gait analysis was performed on a healthy person and a hemiplegic patient using this system. Then a comparison was performed between the results of this simple system and those of a 3D motion analysis system. Knee joint angles obtained by both systems were essentialy the same.
