A novel intervention for upper limb rehabilitation in people with stroke combining myoelectric pattern recognition,...

To explore the perceptions and experiences of people with stroke participating in a novel upper limb intervention, combining myoelectric pattern recognition (MPR), virtual reality (VR), and serious gaming.

Six individuals with chronic stroke and moderate to severe upper limb impairment were interviewed after 18 training sessions delivered over 6 weeks (total average practice time of 21 h). The semi-structured interviews were transcribed and analyzed with qualitative content analysis.

The overarching theme that emerged from the interviews, "Many factors come into play to make it work," included three categories: "The Player - training was rewarding and demanding at the same time," "The Program - a fun way to exercise, but there is more to it," and "The Supporter - a partner hard to replace."

Participants perceived the training as motivating, valuable, and different from their previous rehabilitations. Increased use and awareness of their arm and hand in daily life activities were described as positive. Synchronization between the real and virtual arms, game difficulty level, user interface, electrode placement, and potential independent home use were described as challenges. These findings offer valuable insights for future development and implementation of MPR-driven technologies in stroke rehabilitation.
