Effect of EMG-Triggered Stimulation on Drop Foot after Hemiplegia / 中国康复理论与实践

@#Objective To investigate the effect of EMG-triggered stimulation on drop foot for poststroke hemiplegia. Methods 36 hemiplegic patients were randomized into routine group (n=18) and EMG-triggered stimulation group (triggered group, n=18). 2 groups were assessed by Fugl-Meyer Assessment (FMA), range of motion (ROM) of ankle dorsiflexion and iEMG values before and after treatment. Results The scores of FMA, degrees of ROM, iEMG values of the tibialis anterior, and co-contraction ratio improved in 2 groups after treatment (P<0.05), and the triggered group had better effect than the routine group (P<0.05). Conclusion EMG-triggered stimulation can improve muscle strength, and decrease co-contraction ratio.
