健康中老年踝关节背屈和跖屈肌群最大等长收缩的表面肌电图研究
Characteristics of Surface Electromyography in Maximum Isometric Voluntary Contraction of Ankle Dorsiflex-ors and Plantarflexors in Healthy Middle to Old People
摘要
Abstract
Objective To establish normal reference range of surface electromyography (sEMG) in related myoelectric activity when maximum isometric voluntary contraction of ankle dorsiflexors and plantarflexors in healthy middle to old people. Methods From Septem-ber to December, 2015, a total of 110 healthy people aged 41 to 75 years were divided into 41 to 50 years group, 51 to 60 years group and>60 years group according to age. The integral electrical values were measured in each subject by sEMG technique and analysis system under maximum isometric voluntary contraction of ankle dorsiflexors and plantarflexors. Results and Conclusion Under ankle dorsiflexion and plantar flexion movement modes, no significant difference was found in the integral electrical values of tibialis anterior muscle, long perone-al muscle, short tibial muscle and gastrocnemius among different groups (F<4.545, P>0.05). No significant difference was found in the inte-gral electrical values of different sides and different genders (F<7.028, P>0.05). Normal reference range for integral electrical values was es-tablished under maximum isometric voluntary contraction of ankle dorsiflexors and plantarflexors in healthy people.关键词
