| 目的：观察动态矫正衣对脑卒中患者躯干运动捕捉和患侧肢体表面肌电的即刻影响。方法：20例脑卒中患者分别在穿戴动态矫正衣前后，进行站立位偏瘫上肢前伸够物活动，应用运动捕捉系统对患者躯干前屈、旋转和侧屈运动进行采集分析，应用表面肌电分析系统对偏瘫侧胸大肌、三角肌前束、三角肌中束、斜方肌上部、肱二头肌、肱三头肌、股直肌、臀中肌、胫前肌和腓肠肌的表面肌电积分肌电值(iEMG)和肱三头肌的协同收缩率(CR)进行采集分析。结果：穿戴动态矫正衣后偏瘫上肢前伸够物时的躯干前屈、侧屈角度均较前减小（均P<0.05），三角肌前束、斜方肌上部、三角肌中束、肱二头肌、股直肌、臀中肌和腓肠肌的iEMG值均较前增加（均P<0.05），肱三头肌CR值较前增加（P<0.05）。结论：动态矫正衣可以辅助偏瘫患者姿势稳定，提供躯干支持并限制异常代偿姿势，提高上下肢肌群的运动控制能力。 |

| Objective: To observe the immediate effects of Orthosuit on trunk motion capture and hemiparetic limbs’ surface electromyographic (sEMG) signals in stroke patients. Methods: Twenty stroke patients performed forward stretching activities with hemiplegic upper limb in standing before and after wearing Orthosuit. A motion capture system was used to measure trunk forward flexion, rotation and lateral flexion angles. A sEMG system was used to analyze the integral EMG (iEMG) values of pectoralis major, anterior deltoid fasciculus, middle deltoid fasciculus, upper trapezius, biceps brachii, triceps brachii, rectus femoris, gluteus medius, tibialis anterior and gastrocnemius on the hemiplegic side, as well as the cooperative contraction rate (CR) of the triceps. Results: Compared with no Orthosuit wearing, the trunk forward flexion and lateral flexion angles were reduced with Orthosuit worn when stretching forward (both P<0.05). The iEMG values of anterior deltoid fasciculus, upper trapezius, middle deltoid fasciculus, biceps brachii, rectus femoris, gluteus medius and gastrocnemius were increased (all P<0.05), attaching with the CR values of triceps brachii increased (P<0.05). Conclusion: The Orthosuit can assist hemiplegic patients to stabilize posture, provide trunk support and limit abnormal compensatory posture, as well as improve the motor control ability of upper and lower limb muscles. |
