## VR & Perturbation Training for Fall Prevention
* Research proposal for BGU MSc Physiotherapy focusing on multimodal interventions for older adults.

## Falls: A Major Public Health Challenge
* 28% of adults over 65 fall annually.
* Leading cause of hospitalizations in seniors.
* Current gap: Conventional programs fail to address real-world environmental demands.

## The Formula of Safe Gait
* Requires integration of Cognitive, Motor, and Sensory systems.
* Executive function deficits (attention/decision-making) compromise obstacle negotiation.

## Intervention A: Perturbation-Based Balance Training (PBBT)
* Task-specific training using unannounced surface translations (slips/trips).
* Targets the physical 'Motor System' response using a safety harness.

## Intervention B: Motor-Cognitive Training (VR-TT)
* Treadmill training combined with non-immersive VR.
* Users negotiate virtual obstacles like puddles and hurdles.
* Targets 'Executive Function' and attention.

## Why Combine Them? Historical Efficacy Data
* VR-TT reduces fall rates (IRR 0.58).
* PBBT reduces fall rates by 40-46%.
* Combination targets both reactive physical responses and cognitive planning.

## Research Question
* Does adding VR to Perturbation reactive balance training improve effectiveness compared to PBBT alone in high-risk older adults?

## Study Design: Prospective, Single-Blind RCT
* Experimental Group: PBBT + VR training.
* Control Group: PBBT Only.
* Target Population: Adults 60-90 with history of 2+ falls in last 6 months.

## Eligibility Criteria
* Inclusion: Age 60-90, MMSE score > 21, ability to walk 5 mins.
* Exclusion: Stroke, TBI, PD, or acute orthopedic pain.

## Intervention Protocol
* 6 weeks, 18 total sessions (3 per week).
* 30-minute sessions: 4m warm-up, 24m training, 2m cool down.
* Safety ensured via overhead suspension harness.

## Outcome Measures
* Primary: Incident Rate of Falls (IRR) over 6 months.
* Secondary: Mini-BESTest, Gait speed (10m walk), Falls Efficacy Scale (FES-I).

## Significance & Impact
* Aims to establish a new standard for fall prevention by addressing both physical failure and cognitive deficits.
