| Objective：To explore the application value of surface electromyography （sEMG） in the assessment of school-age children with cerebral palsy. Methods：Sixty children with spastic diplegia received comprehensive rehabilitation treatment. All patients were evaluated by gross motor function measure （GMFM） scale and sEMG before and after training. Integrated electromyography （iEMG）, root mean square （RMS）, mean power frequeney（MPF） ,median frequency（MF） and average EMG （AEMG） were recorded. Results：Three months after the training, the scores of seetions A,B and C of GMFM had no statistical change,while the total scores and scores of the sections D and E were increased significantly （P〈0.01）. The iEMG values of quadriceps and gastrocnemius muscles at functional motion were decreased significantly（P〈0.01）, while the values of RMS, AEMG, MF and MPF had not significant changed, iEMG values of quadriceps and gastrocnemius muscles, RMS and AEMG were increased significantly at MIVC（P〈0.01） ;the value of MF and MPF had no statistical change. Conclusion：The sEMG measurement can reflect the states of muscle function quantitatively,and the sEMG is feasible to assess the rehabilitation effect in children with cerebral palsy. |
