步态康复机器人评价正常老年人步态的性别差异

背景：在国内采用步态康复机器人对正常老年人的步态进行评定的研究较少,且无明确结论。目的：采用步态康复机器人对正常老年人的肌力、关节活动度、痉挛状态等指标进行评定,了解老年人步态的特点。方法：选取健康老年人30名,男15名,女15名,年龄（62.40±1.58）岁。利用步态康复机器人的评估工具L-FORCE,L-STIFF和L-ROM测试受试者的肌力、痉挛状态和关节活动度。结果与结论：老年人L-FORCE测试结果显示,双侧髋屈肌力和双侧膝屈伸肌力在健康老年人不同性别间差异有显著性意义（P〈0.05）。老年人L-STIFF测试结果显示,60（°）/s左髋伸、120（°）/s左髋屈伸痉挛状态在不同性别间差异有显著性意义（P〈0.05）。老年人L-ROM测试结果显示,健康老年人行走时关节活动度不存在性别差异（P〉0.05）。提示老年男性下肢肌力大于女性;老年男性L-STIFF测试结果高于老年女性,提示治疗师在对患者进行L-STIFF评价时要考虑性别因素;健康老年人关节活动度不存在性别差异。

Evaluation of gender differences for gait in normal elder by the gait rehabilitation robots

BACKGROUND：In China,there are few studies on the evaluation of gait in normal elder by using gait rehabilitation robot,but no definitive conclusion is drawn.OBJECTIVE：To evaluate the indicators of the muscle force,range of motion （ROM）,spasticity and so on by using the gait rehabilitation robot,so that to understand the feature of the gait in the elder people.METHODS：A total of 30 healthy elder people were selected with the age of （62.40±1.58） years old including 15 males and 15 females.The muscle force,spasticity and ROM of all the people were tested with the assessment tools of L-FORCE,L-STIFF and L-ROM in the gait rehabilitation robot.RESULTS AND CONCLUSION：Results of L-FORCE of the elder subjects were indicated that the bilateral hip flexor forces and bilateral knee flexor and extensor forces were different in different genders,which showed significant difference （P〈0.05）.Results of L-STIFF of the elder subjects were shown that 60 （°）/s left hip extension,120 （°）/s left hip flexion and extension spasticity in different genders were different,which had significant difference （P〈0.05）.Results of L-ROM of the elder subjects showed that there was no difference of ROM in different genders （P〉0.05）.It is indicated that the value of L-FORCE and L-STIFF of healthy elder people are higher in the male than those of in the female.The therapists should consider gender factors in the evaluation of patients with L-STIFF and there is no difference of L-ROM in different genders.
