Effects of a wearable sensor-based virtual reality game on upper-extremity function in patients with stroke

Area of Science:

• Neurorehabilitation
• Virtual Reality in Medicine
• Stroke Recovery

Background:

• The PABLO system, a virtual reality game utilizing motion sensors, has limited investigation in stroke rehabilitation.
• This study addresses the need to evaluate the PABLO system's efficacy for upper-extremity recovery in stroke survivors.

Purpose of the Study:

• To investigate the effects of upper-extremity virtual reality training with the PABLO system on stroke patients.
• To compare the PABLO system's effectiveness against standard rehabilitation methods.

Main Methods:

• 19 stroke patients were assigned to virtual reality training and 18 to standard rehabilitation.
• 18 sessions were conducted twice weekly, with outcomes measured by the Fugl-Meyer Assessment-Upper Extremity, range of motion, dexterity, grip strength, and the Stroke Impact Scale.
• Patient enjoyment and side effects were also recorded.

Main Results:

• No significant difference was found in the primary outcome (Fugl-Meyer Assessment-UE) between groups.
• The virtual reality group showed significantly greater improvements in hand dexterity (p=.05), shoulder flexion (p=.03), and elbow pronation (p=.03).
• Participants in the virtual reality group reported significantly higher enjoyment of rehabilitation activities (p=.01).

Conclusions:

• PABLO system-based virtual reality interventions enhance upper extremity function, including hand dexterity and shoulder/elbow mobility, in stroke patients.
• Virtual reality training with the PABLO system offers a more engaging rehabilitation experience compared to traditional treatments.
• The findings support the integration of PABLO virtual reality into stroke rehabilitation protocols for improved outcomes and patient satisfaction.
