Evaluation of Japan Stroke Scale of Motor (JSS-M)-From Rehabilitative Viewpoint

In 1997, the members of Japan Stroke Society presented the Japan Stroke Scale (JSS) for the acute stage, and in 2000 the Japan Stroke Scale of Motor (JSS-M) with the items of motor system required for the independence of activities of daily living (ADL). JSS-M consists of eight major items. We classified subjects with nine points or less into group A, with 10-19 points into group B and with 20 points or more into group C according to JSS scores for the acute stage at the baseline. In JSS scores, higher scores means more intense severity of disability. Subjects were 46 cases with cerebral hemorrhage and 63 cases with cerebral infarction, 109 cases in total. Age: cases with cerebral hemorrhage had a mean age of 58.3 ± 14.7, while those with cerebral infarction had a mean age of 69.2 ± 11.0: males 67, and females 42. The rate of improvement of cerebral hemorrhage was higher than that of cerebral infarction in groups A and B. The rate of improvement was the highest in Gait in groups A and B, and Dysphagia and Complex Movement followed in order after that; in group B the rate of improvement of Hand and Arm followed after Complex Movement. The mean rate of improvement of JSS was 98% in group A, 66.7% in group B, and 57.8% in group C. JSS-M is a very useful evaluation, but the study of evaluation methods of trunk and upper limb function required.
