摘要: 目的 将关节运动轨迹捕捉与表面肌电图技术运用于评估婴幼儿爬行运动中。方法 2015年12月至2016年6月,对12例正常婴幼儿和13例运动发育迟缓婴幼儿,采用三维步态分析系统采集膝爬运动中上肢主要关节的运动轨迹,记录主要活动肌肉的表面肌电信号。结果 运动发育迟缓婴幼儿右侧肩关节活动角度范围高于正常婴幼儿(t=2.576, P<0.05),左右侧肱三头肌表面肌电均方根差值大于正常婴幼儿(t=2.448, P<0.05)。结论 关节运动轨迹和表面肌电图运用于运动发育迟缓婴幼儿膝爬运动,可以为制定个性化早期合理的康复训练提供依据。

Abstract: Objective To detect kinematics and surface electromyography (sEMG) of upper limbs in normal children and motor-delayed children for clinical assessment. Methods From December, 2015 to June, 2016, twelve healthy children and thirteen children with motor developmental delay less than two years old were analyzed kinematics with Motion Analysis system and sEMG. Results The angle of motion of right shoulder was more in the motor-delayed children than in the normal children (t=2.576, P<0.05). The difference of root mean square values of bilateral triceps brachii was more in the motor-delayed children than in the normal ones (t=2.448, P<0.05). Conclusion Detecting kinematics and sEMG may supply information for early personalized treatment strategy.
