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.

Key words: motor developmental delay, crawling, kinematics, surface electromyography
