Balancing new technology: Virtual reality for balance measurement case report.

Area of Science:

• Biomechanics
• Rehabilitation Technology
• Human Movement Science

Background:

• Falls are a leading cause of injury deaths globally, necessitating effective balance assessment tools.
• Chronic and acute conditions, including neurological diseases and sports injuries, often impair balance.
• Virtual Reality (VR) presents a novel therapeutic platform for balance assessment and rehabilitation.

Observation:

• The VRSway VR application utilizes headset and controller sensors to measure postural stability.
• It quantifies balance by analyzing spatial location relative to the center of mass and calculating stability indexes.
• This case study compared VRSway measurements to the gold standard, force plate technology, in two healthy participants.

Findings:

• VRSway measurements demonstrated high correlation with force plate data across multiple metrics.
• Sway index, total displacement, center of pressure mean velocity, and ellipse area/radii showed strong agreement (r > 0.935, P < .001).
• The VRSway stability score effectively validates balance evaluation compared to traditional methods.

Implications:

• VRSway is a potentially valid and novel method for evaluating balance using VR technology.
• This technology could enhance clinical decision-making for balance risk management and rehabilitation strategies.
• Further research with larger, diverse cohorts is needed to explore broader applications of VR-based balance assessment.
