sEMG-controlled forearm bracelet and serious game-based rehabilitation for training manual dexterity in people with multiple sclerosis: a randomised controlled trial.

Only 30 people completed, all from one MS association, so the sample was small and selected. Everyone had EDSS scores between 3.0 and 7.5, so it does not show what happens in people outside that disability range. The experimental group received conventional physical therapy, the MYO sensor, and video games together, so the study cannot show which part produced any effect. Follow-up was only 15 days, so longer-term effects are unknown. The Box and Blocks groups started at different levels, which makes it hard to judge whether the added technology changed dexterity.

The study was funded by Comunidad de Madrid and Ministerio de Economía y Competitividad. The supplied text gives no conflict-of-interest declaration beyond this funding statement.

Do not conclude that the MYO bracelet alone improves hand dexterity or grip strength. The main dexterity outcome was null, and the bracelet was used together with conventional physical therapy and video games, so the contribution of the bracelet alone cannot be separated.
