1 瘫痪肢体的病理改变 肢体瘫痪是中风病人常见的运动功能障碍,使病人的活动受到限制,劳动力丧失,生活自理能力差,有的甚至成为终身残废。 患侧上肢呈内收、内旋的挛缩位。上肢的屈肌群较伸肌群占优势。当瘫痪上肢的肌张力增高时,屈肌的张力增高更显著;肩部的背阔肌和胸大肌占优势。当上肢不固定时,背阔肌与胸大肌共同作用将肩向内拉,使肩关节处于内收、内旋。另外上臂、 A paralyzed limb pathological changes Paralyzed limbs stroke patients common motor dysfunction, the patient’s activities are limited, the loss of labor, poor self-care ability, and some even become disabled for life. Ipsilateral upper limb adduction, internal rotation of the contracture. The upper extremity flexor group is more dominant than the extensor group. When paralyzed upper limb muscle tension increased flexor tension increased more pronounced; shoulder latissimus d and pectoralis predominate. When the upper limb is not fixed, the latissimus dorsi and pectoralis major muscles will pull the shoulder to the shoulder so that the shoulder adduction, internal rotation. In addition, the upper arm,
