## Adding Virtual Reality to Perturbation-Based Balance Training
- Research proposal from Ben-Gurion University, Dept of Physical Therapy.
- Objective: Reducing fall risk in older adults through a Randomized Controlled Trial.

## The Clinical Need: Fall Statistics
- 28% of adults over 65 fall annually.
- Healthcare costs reach approximately $50B/year in the USA.
- Most falls occur due to unexpected perturbations or dual-task interference.

## The Formula for Safe Gait
- Integration of three systems: Cognitive Function (executive tasks), Motor System (balance recovery), and Sensory System (visual/vestibular inputs).

## Research Methodology (PICO)
- **Population**: 60 older adults, ages 65-90.
- **Intervention**: PBBT + Virtual Reality (cognitive-motor challenges) 3x/week for 6 weeks.
- **Comparison**: PBBT treadmill training alone.
- **Outcome**: Primary measure is the fall rate in the 6 months post-training.

## Eligibility Criteria
- **Inclusion**: History of 2+ falls in last 6 months, walk 5 mins unassisted, MMSE > 21.
- **Exclusion**: Psychiatric/neurological damage, severe orthopedic issues, or sensory impairment.

## Protocol: Controlled Progression
- **PBBT Progression**: Increasing perturbation velocity (0.1–3.2 m/s) and acceleration (0.5–16.0 m/s²).
- **VR Progression**: Increasing obstacle height, frequency, and navigation complexity.

## Outcome Measures
- Primary: 6-month fall rate.
- Secondary: BERG Balance Scale, Timed Up and Go (TUG), Four Square Step Test (FSST), and FES-I.

## Significance and Limitations
- Potential to create a new standard of care for aging populations and Parkinson's/Stroke patients.
- Study limitations include small sample size (N=60) and potential recall bias in self-reported falls.
