Electromyogram-triggered neuromuscular stimulation for improving the arm function of acute stroke survivors: A randomized pilot study

Efeitos da estimulação elétrica funcional nos músculos do punho e dedos em indivíduos hemiparéticos: uma revisão sistemática da literatura

“…powell et al 10 found significant gains in the grip and grasp subscores of the Action Research Arm Test when compared to a control group. Chae et al 9 and Francisco et al 11 observed significant motor gains for the intervention group compared to the control group by means of measurements taken with the Fulg-Meyer test (Fm). there is strong evidence of motor gain after FES.…”

“…Four studies 7,[17][18][19] had a sample with chronic stroke diagnosis, with post-lesion peri- ods varying from 1 17 to 4 ½ years 18 . Sample size varied from 9 11 to 48 10 subjects divided between treatment and control groups. the participants' average age group was 59 9 to 69 10 .…”

“…Session duration varied from 10 minutes 7 to 6 hours 18 . Current parameters varied, with frequency ranging from 20 to 100 hz 11 , amplitude from 14 17 to 60 ma 9 and pulse width from 200 to 300µs 9,10 . In most studies, FES was applied to extensor muscles [9][10][11][17][18][19] ; in one study it was applied to wrist and finger flexors 7 and in another, to both muscle groups 4 .…”

“…of the four RCts [9][10][11]17 that assessed motor function, three [9][10][11] showed positive effects after FES. powell et al 10 found significant gains in the grip and grasp subscores of the Action Research Arm Test when compared to a control group.…”

“…various clinical trials document the effects of FES on the wrist and fingers of hemiparetic patients [9][10][11] . therefore, a systematic review of literature would aid intervention planning by providing a synthesis of the evidence on the effects of this therapeutic resource 12 .…”
