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

ABSTRACT

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