title: [Study on surface electromyography characteristics of human upper limb during daily living activities].
abstract: This study on the surface electromyography (sEMG) characteristics of human upper limb during the Activities of Daily Living (ADLs) was aimed to deliberate over the precise evaluation index for the muscle function of human upper limb, and for the significance of muscle function prediction, diagnosis and rehabilitation evaluation, thus providing the design parameters for prosthetic devices. 20 normal adults (10 males and 10 females) were recruited. They each performed 13 basic actions of left and right upper limb; then they repeated each action 3 times. The sEMG signals of ten muscles (the middle of deltoid, biceps brachii, triceps brachii, palmaris longus, extensor digitorum) were tested by 8-channel sEMG collected system. The eigenvalue of Average electromyography (AEMG) and Integral electromyography (IEMG) were processed by SPSS 14. 0. The sEMG characteristics of main muscles (the middle of deltoid, biceps brachii, triceps brachii, palmaris longus, extensor digitorum) during the ADLs were obtained and analyzed. The conclusion is that Man and Woman should be different in using muscle force; man should focus on the strength of extensor digitorum, while woman should enhance the strength of palmaris longus when the elderly and the disabled performed rehabilitation training. Biceps brachii is important both in man and woman during the ADLs; deltoid and triceps brachii are less important. There is no significant difference in sEMG between left and right main muscles. At the same time, AEMG is consistent with IEMG in evaluating the muscle function.
