Video Game-Based Trunk Exercises for Rehabilitation in Chronic Stroke Survivors: A Mixed-Methods Feasibility Study

Area of Science:

• Rehabilitation medicine
• Neuroscience
• Human-computer interaction

Background:

• Chronic stroke survivors often experience impaired trunk control, impacting mobility and independence.
• Traditional rehabilitation methods may lack engagement for long-term adherence.
• Video game-based interventions offer a novel approach to enhance motor function and patient motivation.

Purpose of the Study:

• To evaluate the feasibility of using the Valedo system for video game-based trunk exercises in individuals with chronic stroke.
• To assess recruitment, retention, adherence, and safety of this novel intervention.
• To gather qualitative insights into participants' experiences with the Valedo system.

Main Methods:

• Ten chronic stroke survivors completed 18 sessions of Valedo-based trunk exercises over 6-8 weeks.
• Feasibility was quantitatively assessed using the Psychosocial Impact of Assistive Devices Scale (PIADS) and adherence metrics.
• Qualitative data were collected through semi-structured interviews and analyzed thematically.

Main Results:

• High adherence (96.11%) was observed among the ten participants who completed the study.
• No serious adverse events occurred, though some experienced transient trunk muscle tightness and fatigue.
• Participants reported perceived safety and benefit, despite encountering some physical and cognitive challenges during gameplay.

Conclusions:

• The Valedo system presents a feasible approach for delivering trunk exercises to chronic stroke survivors.
• The intervention demonstrates potential for safe and engaging rehabilitation, though challenges require consideration for future implementation.
• Further research should explore optimizing the Valedo system for diverse chronic stroke populations.
