## Research Proposal: VR-Augmented Perturbation Training
* **Title:** Addition of a non-immersive Virtual Reality component to Perturbation-based Balance Training (PBBT) to reduce fall risk in older adults.
* **Institution:** BGU, MSc Physiotherapy, January 2026.

## The Challenge: Falls in Older Adults
* 28% of adults over 65 fall annually.
* Key causes: Tripping, poor obstacle negotiation, and cognitive processing deficits in complex environments.

## Components of Training
* **PBBT:** Reactive balance control using unannounced treadmill translations (slips/trips).
* **Motor-Cognitive VR:** Simulates real-world scenarios (puddles, hurdles) to address attention and executive function.

## Study Design: Prospective Single-Blinded RCT
* **Intervention Group:** 18 sessions of PBBT + VR cognitive challenges.
* **Control Group:** 18 sessions of PBBT alone.
* **Protocol:** 6 weeks, 3 sessions/week, ~30 mins per session.

## Target Population
* **Inclusion:** Ages 60–90, history of 2+ falls in 6 months, MMSE > 21.
* **Exclusion:** Major psychiatric/neurological history, acute walking-related pain.

## Evidence and Outcome Measures
* **Previous Data:** RBT reduces fall rates by 40-46%; VR-TT by up to 50%.
* **Primary Outcome:** Incident Rate of Falls (IRR) over 6 months.
* **Secondary Outcomes:** Mini-BESTest, SPPB, Gait Variability, and Executive Function (Trail Making Test B).

## Clinical Significance
* Attacks fallback etiology from two sides: reactive capability (motor) and cognitive processing (VR), aiming to set a new standard for geriatric rehabilitation.
