[Biomechanic and electromyography studies of gait in healthy subjects and patients with coxarthrosis]

This report deals with electromyographical-kinesiological examinations of 40 unimpaired subjects and 31 coxarthrosis patients before and 3 months after implantation of an artificial hip joint on a level gaitway 12 m in length with a newly developed computer-controlled measuring system. The accomplished gait analyses served the purpose of determining biomechanical and electromyographical norm values and tolerance levels of unimpaired test subjects and recognizing pathological aberrations as well as determining the success of therapeutical measures. The results showed that despite greater freedom of joint movements observable postoperatively, the muscle actions of the patients did not come to equal those of the unimpaired subject group.
