Abstract
For many years, motion analysis has played a very important role in the medical and sports fields. However, conventional motion analysis method needs large space and has many restrictions . Therefore, in medical fields, the conventional method is limited to laboratory research and can't be used in everyday applications. These problems can be resolved by using wearable sensor systems. Lately, many researches have been done on wearable sensors. Therefore, by using wearable sensors, motion analysis will helps many patients efficient recovery. On the other hand Numerical simulation using multibody dynamic analysis for human body helps to understand what is going on. Recently analysis method has become to be very powerful to understand complex phenomena and demonstrate what kind of rehabilitation is most effective. In the fields of sports training, measurement system and analysis method is considered to play similar role as in medical fields. In the near future, combination of wearable sensors and multibody dynamic analysis will plays much more important role.
