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 de-velopmental 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.
