[Treatment of deformities of the locomotor system in hemiplegia]

In spastic hemiplegia mainly one side of the body is affected. In both the upper and the lower extremity the distal parts (hand and foot) are more severely involved than the proximal region. In cases of minor involvement the goal of treatment in the upper extremity is to achieve functional improvement by means of splinting and surgery. In cases of severe alterations cosmetic improvement without much functional gain is all that can be expected. Gait analysis has demonstrated that there are four basic patterns that can be related to the severity of involvement. In type I muscle imbalance exists without a contracture. In type II there is contracture of the muscles of the posterior compartment of the calf. In type III, in addition to the changes around the ankle joint, contractures around the knee are present, and in type IV also hip problems. Functional improvement can be achieved by means of splinting and surgery in all types. Basic principles of treatment have developed as a result of the application of gait analysis and dynamic electromyography. Specific examples of such treatment principles have recently been presented by Gage.
