Proposal of a Serious Game for Dynamic Balance Training Using a Force Platform: A Pilot Study

Area of Science:

• Gerontology
• Rehabilitation Engineering
• Game Design

Background:

• Physical training programs for elderly balance show promise but struggle with participant consistency.
• Developing engaging and accessible rehabilitation tools is crucial for sustained therapeutic effects.

Purpose of the Study:

• To develop and validate a laterolateral balance simulation game for supporting balance rehabilitation.
• To encourage consistent participation in balance training through an interactive and personalized approach.

Main Methods:

• A balance simulation game was developed using Unity and Blender, controlled by a biaxial force platform.
• Validation included structural tests, usability testing (System Usability Scale), and a pilot study with 10 healthy young volunteers.
• Statistical analysis employed Shapiro-Wilk and t-Student tests (P < 0.05) using Jamovi software.

Main Results:

• The game demonstrated expected performance, with usability testing yielding an excellent score of 81.5 points.
• Pilot testing indicated personalized training effectiveness, with volunteers showing score improvements across multiple sessions (e.g., 17.6%, 26%, 8.5%).
• The simulation accurately replicated foot pressure movements for avatar control, confirming its efficacy.

Conclusions:

• The developed balance simulation game is a viable, user-friendly tool for personalized balance rehabilitation.
• Individualized calibration enhances accessibility and engagement, suggesting potential for improving balance in target populations.
• Future research will focus on elderly participants, extended training protocols, and muscle activation analysis.
