Abstract

The motion analysis method has been a popular and valid tool used to evaluate the gait function and human movement. The motion analysis provides scientific tools in several fields to perform accurate functional evaluations and analyses for clinical and research oriented purposes such as performance enhancement, injury prevention, return to activity and effects of orthopedic/athletic devices. It also provides valuable information for physicians, therapists, trainers, prosthetic/orthotic designers and couches in designing treatment programs, training methods, design criteria and rehabilitation protocols for individuals. Recently, this technique has been applied in the investigation of hand movement. In the first part of this article, the image-based motion analysis system and its applications are described. Secondly, the basic concepts and the operation of motion analysis are briefly addressed. A typical kinematic analysis by the image-based motion analysis method consists of four distinct parts: data collection, digitizing or marker detection, computation and presentation of the results. The final part of this article presented research examples of evaluation of hand function using motion analysis. In this section, the use of motion analysis for investigating the hand function from the biomechanical point of view was exemplified
