Physical therapy and rehabilitation.

The literature on physical therapy and rehabilitation in osteoarthrosis of the hip and knee joint has been reviewed. The number of controlled clinical studies is rather limited and the clinical material is generally not clearly defined. It may be concluded, however, that the effect of short-wave, micro-wave and ultrasound on joint pain is not superior to that of sham treatment. Ice therapy and transcutaneous nerve stimulation appear to be of definite value, but the effect is transient. Controlled trials indicate that mobilization of joint and muscle contractures is facilitated by diathermy and ultrasound. Training of muscle function should include training of endurance and balance reaction. Technical aids and training of activities of daily living are an important part of the rehabilitation program, that has to be based on the functional problems experienced by the patient.
