Effects of Balance Training Using a Virtual Reality Program in Hemiplegic Patients

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Human Movement Science

Background:

• Hemiplegic patients with neurological impairments aim to improve independence.
• Wii Fit balance training has shown prior effectiveness.
• Long-term intensive training's impact on quality of life needs further investigation.

Purpose of the Study:

• To investigate the influential outcomes of long-term intensive Wii Fit balance training on quality of life in hemiplegic patients.
• To compare Wii Fit balance training with conventional balance training.
• To identify key factors influencing quality of life post-intervention.

Main Methods:

• A randomized controlled trial comparing Wii Fit balance training (intervention group, n=21) with conventional balance training (control group, n=20).
• Both groups received 15 sessions (30 min each) twice weekly for 8 weeks.
• Outcomes measured included balance confidence, activities of daily living, body composition, and quality of life (EuroQoL Visual Analogue Scale).

Main Results:

• The intervention group showed significant improvements in balance confidence, activities of daily living, fat proportion, and metabolic rate compared to the control group (p < 0.05).
• Balance confidence was identified as a significant predictor of quality of life (EuroQoL Visual Analogue Scale) via stepwise multiple regression.
• Wii Fit training helped patients overcome asymmetrical weight distribution through self-modulating biofeedback.

Conclusions:

• Wii Fit balance training, utilizing virtual reality and biofeedback, effectively improves the quality of life for hemiplegic patients.
• The intervention enhances both functional outcomes (balance, daily activities) and physiological factors (body composition).
• Improved balance confidence is a key driver for enhanced quality of life in this population.
