【摘要】：目的:应用三维运动采集系统分析健康中老年人利手和非利手侧上肢饮水动作的运动学特点,探讨利手和非利手执行特定功能性动作是否存在差异性。方法:用Vicon Nexus运动采集系统对18名右利手健康中老年人左右侧上肢执行饮水动作的运动轨迹进行采集,分析并比较利手和非利手侧肩、肘和腕关节的三维运动角度变化及角速度峰值。结果:肘关节X、Y、Z轴上运动角度利手和非利手侧比较差异有显著性意义(P0.05)。在角速度方面,双侧肩关节X轴上最小值、肘关节Y轴和Z轴的最大值及最小值、腕关节Y轴的最大值比较差异有显著性意义(P0.05)。结论:健康中老年人在执行饮水动作时,利手侧肘关节的屈伸幅度显著高于非利手侧;而非利手侧肘关节内收外展和内外旋运动角度及角速度显著高于利手侧。
[Abstract]:Objective: to analyze the kinematic characteristics of the drinking water movement of the upper limbs of the healthy middle and old people by using the three-dimensional motion collection system. To explore whether there are differences between hand and non-hand in performing specific functional actions. Method: use Vicon. Nexus motion acquisition system was used to collect the track of the left and right upper limbs of 18 healthy old people with right handedness. The angle change and the peak angular velocity of the lateral shoulder elbow and wrist joint were analyzed and compared. Results: the elbow joint XY. The angle of motion on Z axis was significantly different from that on non-hand side (P 0.05). In terms of angular velocity, the minimum value on X axis of bilateral shoulder joint, the maximum value and minimum value of Y axis and Z axis of elbow joint. There was significant difference in the maximum value of Y axis of wrist joint (P 0.05). Conclusion: the flexion and extension range of the elbow joint in the hand side is significantly higher than that in the non hand side in the healthy middle-aged and old people. The angle and angular velocity of the adductive abduction and internal and external rotation of the non-hand elbow joint were significantly higher than those of the hand-free side.

【正文快照】： 上肢运动功能是日常生活活动(activities ofdaily living,ADL)基本动作执行和完成技巧中的重要组成部分,如伸手够物、抓取和放开、转移物品、进食、修饰等[1—2]。老年人的生活质量很大程度取决于ADL能力[3],脑功能障碍者上肢通常较难完成日常活动[4]。有研究发现利手在参与日
