Non-fatal stroke constitutes one of the major causes of disability in old age 1, 2. Both NMES protocols proved evidence of improvements in measurements related to hand motor recovery in older adults following a stroke, nevertheless, these findings showed that the specific stimulation frequency had different effects depending on the clinical measures under study. Additionally, there were no significant differences between the groups in the Box and Block Test. The 35 Hz NMES intervention showed a significant effect on Barthel Index. NMES groups showed significant changes (pā<ā0.05) with different effect sizes in range of motion, grip and pinch strength, the Modified Ashworth Scale, and the muscle electrical activity in the extensors of the wrist. They were collected at baseline, after 4 and 8 weeks of treatment, and after a follow-up period. Outcome measures included motor impairment tests and functional assessment. Sixty nine outpatients were randomly assigned to the control group or the experimental groups (NMES with 50 Hz or 35 Hz). A randomised clinical trial was conducted to compare the effects of two NMES protocols with different stimulation frequencies on upper limb motor impairment and function in older adults with spastic hemiparesis after stroke. More solid data are needed regarding the application of neuromuscular electrical stimulation (NMES) in the paretic hand following a stroke.
