Immersive Virtual Reality based Rehabilitation In Improving Functional and Balance Deficits Following Lateral Ankle Sprain

Background & Rationale

The ankle-foot complex plays a critical role in human movement, and its stability is essential for activities like walking, running, and jumping. Lateral ankle sprains (LAS) are among the most common musculoskeletal injuries, affecting both the general population and athletes (Munn et al., 2010). Improper healing or recurrent sprains can lead to chronic ankle instability (CAI), which impairs proprioception and balance (Griffith & Brockwell, 2006).

Virtual Reality (VR) rehabilitation offers an interactive platform that enhances proprioception, joint function, and balance control through immersive, sensorimotor feedback mechanisms (Schultheis & Rizzo, 2001; Vernadakis et al., 2014). While previous research has focused on semi-immersive VR, this study will examine the effects of immersive VR-based rehabilitation using a head-mounted display (HMD) in individuals with lateral ankle sprains.

Research Question

What are the effects of immersive virtual reality-based rehabilitation interventions on improving functional and balance deficits among individuals following a lateral ankle sprain?

Hypothesis

Experimental Hypothesis

Subjects who undergo immersive VR-based rehabilitation following a lateral ankle sprain will show significant improvements in function and balance compared to those receiving traditional rehabilitation alone.

Null Hypothesis

There will be no significant difference in the effectiveness of immersive VR-based rehabilitation in improving functional and balance deficits following a lateral ankle sprain.

Study Objectives

To evaluate the effectiveness of immersive VR-based rehabilitation in improving balance and functional deficits following a lateral ankle sprain.

Expected Outcomes & Clinical Significance

VR-based rehabilitation is expected to enhance proprioception, balance, and functional recovery in individuals with lateral ankle sprains. The immersive environment may improve motivation, adherence, and engagement in rehabilitation (Burdea, 2003). This study may support the integration of immersive VR into physiotherapy protocols for ankle rehabilitation.
