進行性筋ジストロフイー症患者の四肢筋力分布について

抄録

Twenty-six patients of progressive muscular dystrophy were examined on muscle testing for the purpose of studying the disturbance of gait. The relationship between the muscle power, grading of this disease and joint contractures were investigated.
On the hip joint, the weakening of the extensor power was inversely proportional to the grading of this disease and the degree of contracture of joint. The walkable patients had stronger muscle power than the not walkable patients and no joint contracture.
On the knee joint, the weakening of the extensor power was also inversely proportional to the grading of this disease and the degree of contracture of joint. But no considerable differences of the extensor power was presented between these patients. While no contracture was observed on the walkable patients, the patients with contracture of this joint could not walk even when they had stronger muscle power than some walkable patients. By this reason, the prevention of contracture of the knee joint is a very important problem of this disease.
