Usability, Acceptability, and Feasibility of a Personalized Adaptive Mirror Therapy for Upper-Limb Poststroke Rehabilitation Using Immersive Virtual Reality and Myoelectric Control: Single-Arm Pre-Post Study.

It was a single-arm pilot with no control group, so it cannot show that the VR therapy caused any change. Only twelve of fifteen recruited participants completed enough sessions for the usability analysis. The study did not analyse motor recovery outcomes, so it cannot support claims about improved arm function. The system combined VR, mirror therapy, muscle-signal control, and therapist supervision, so the study cannot separate the contribution of each component. Subgroup comparisons by age and impairment were exploratory and not powered for definitive differences. Therapist assistance time, learning curves, and independence were not quantified. Safety and adverse events were not systematically measured, although no adverse events were observed. The therapy was supervised in a clinic, so these results do not show it is feasible for fully autonomous home use.

The authors declared no conflicts of interest. No funding source is stated in the supplied text.

Do not conclude that this combined VR mirror therapy with muscle-signal control and therapist supervision improves arm movement or is ready for unsupervised home use. It was a small supervised pilot that measured user experience and did not analyse motor recovery outcomes.
