## Add-On VR to Perturbation-Based Balance Training
- Proposal for a Randomized Controlled Trial concentrated on elder fall prevention.
- Study investigates if synchronizing VR with physical platform perturbations enhances motor learning.

## Scientific Background: The Challenge of Falls
- 28% of adults over 65 fall annually, causing significant ER hospitalizations.
- 85% of falls occur during walking due to unexpected trips or slips.
- Key factor: Integration of motor, sensory, and cognitive systems.

## The Missing Link: Reactive vs. Proactive
- Proactive: Anticipatory response.
- Reactive: Compensatory adjustments (righting reflex).
- Technology used: BalanceTutor (mechanical) and GaitBetter VR (cognitive).

## Study Design and Intervention
- Target Population: Adults 60–90 with a history of falls and MMSE > 21.
- Group 1: Perturbation-Based Training (PBT) + VR (motor-cognitive obstacles).
- Group 2: PBT only (mechanical perturbations only).

## Outcomes and Efficacy
- Primary Outcome: Incident Rate of Falls (IRR) over 6 months.
- Secondary Outcomes: SPPB, Mini-BESTest, gait speed, and Quality of Life (SF-36).
- Training Progression: 18-24 difficulty levels increasing platform displacement up to 18cm.

## Significance of the Study
- Aims to address the 40-46% efficacy gap in current fall prevention by combining reactive and planned motor-cognitive processing training.
