Chronic stroke survivors' perspective on the use of serious games to motivate upper limb rehabilitation - a qualitative study.

Upper limb paresis occurs quite commonly after stroke and may result in the affected limb's disuse or learned non-use. As a result, its cortical representation may be suppressed, further inhibiting its spontaneous utilization, resulting in motor function deterioration, increase in spasticity, joint stiffness and pain.The aim of this work was to involve stroke survivors in a qualitative study within a user centred design process to better understand the perspectives of stroke survivors on virtual reality - based serious games (SG) for upper limb rehabilitation during the chronic phase and use those insights to design a VR-based serious games which promotes activation of the affected cortical area.A qualitative research method was performed using a multi professional focus group discussion, including a representative group of stroke survivors.With the insights of this work, the authors initiated the design of a VR-based SG prototype for upper limb rehabilitation with two modes, one version to be played with any arm to pick a virtual hammer and hit targeted objects, and other version, a mirror version based on mirror therapy.
