[The effectiveness of physical therapy techniques. Possibilities of electromyography evaluation]

The purpose of this study is to verify the efficiency of selected physiotherapeutic techniques. EMG analysis with surface electrodes was performed in order to obtain sufficient data about the process of local strain. Furthermore, the local strain of the muscles surrounding a healthy knee is compared with the local strain of muscles after a knee injury (ACL-rupture) with resultant atrophy. The results prove modifications of progress and amplitudes of local strain and of coordination affected by atrophy/non-atrophy. On account of the first results additional research is recommended to investigate the specific aims of the different techniques.
