Electromyographic biofeedback improves upper extremity function: a randomized, single-blinded, controlled trial

ObjectiveTo examine the effects of a 6-week surface electromyographic biofeedback intervention on the re-learning of upper extremity motor function in subjects with paretic upper extremity after stroke.DesignA randomized controlled trial.SettingState Centre of Attention to Brain Injury, Madrid, Spai...

The sham BFB group (n = 19) received a sham intervention.Outcome measuresUpper extremity motor function assessed using the Fugl-Meyer Assessment-Upper Extremity Scale (66 points), the glenohumeral active range of motion, and the electromyographic amplitude signal of the middle deltoid and upper trapezius muscles were collected at baseline, after the intervention, and at the one-month follow-up.ResultsCompared with the sham BFB group, the sEMG-BFB group experienced significant increases in upper extremity motor function after the intervention. The mean differences between groups were as follows: 4.79 points (95% CI 2.92 to 6.66) after the intervention; 6.55 points (95% CI 3.75 to 9.34) at the one-month follow-up; improved active range of motion 15.75 points (95% CI 6 to 30) after the intervention and electromyographic activity in the upper trapezius muscle changed in favour of the sEMG-BFB.ConclusionsIn the short term, a 6-week sEMG-BFB intervention effectively improved paretic upper limb motor function. Future research is needed to determine if the sEMG-BFB intervention has any long-term effects.Elsevier202520252021info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://www.sciencedirect.com/science/article/pii/S003194062030016Xhttps://hdl.handle.net/10578/41194reponame:RUIdeRA.
