非麻痺側腰背筋の筋緊張亢進により、麻痺側上肢に著明な連合反応が誘発された脳血管障害患者に対する筋電図学的検討

The purpose of this study was to investigate the trunk muscles causing associated reactions in a hemiplegia patient with cerebrovascular disoders. Clinical evaluation and surface electromyographic based motion analysis were performed to confirm impairment problems in the patient. He showed associated reaction of left elbow flexion and left forearm supination caused by left anterior tilt to right posterior tilt of the trunk in the stance phase shift to the swing phase in gait. Surface electromyographic evaluation was performed while practing a similar gait task. The results indicated that high muscle activity of the affected side biceps brachii muscle was caused by high muscle activity of the unaffected side low back muscles. These finding suggest that not causing hypertonia of unaffected side low back muscles in normal movement of gait is very important.
