# Efficacy of an innovative PT program to enhance mobility in older Veterans with slow walking speed

## TL;DR

A new physical therapy program called LLWS significantly improved walking speed and mobility in older Veterans with slow walking speed.

## Contribution

The study demonstrates the efficacy of the Live Long Walk Strong (LLWS) program in improving mobility in older Veterans.

## Key findings

- LLWS participants showed significantly faster walking speed (mean change 0.08±0.02 m/s) after the 8-week program.
- LLWS participants had greater improvements in the Short Physical Performance Battery and Activity Measure for Post Acute Care.
- The improvements were statistically significant and clinically meaningful.

## Abstract

We investigated the efficacy of an innovative physical therapy program targeting mobility known as Live Long Walk Strong (LLWS). This was a single-blind randomized controlled trial conducted at an outpatient VA tertiary care center among community-dwelling middle-aged and older Veterans with slow walking speed. LLWS is an 8-week 10 (1-hour/session) session outpatient physical therapy program. It was designed to enhance mobility by targeting impairments linked to mobility decline and fostering long-term engagement in physical activity through coaching and behavior change strategies. LLWS treatment was compared to participants within a waitlist control group. Walking speed was the primary outcome and secondary outcomes included measures of mobility. We randomized 150 participants and experienced a 25% dropout rate, which was in part due to the COVID-19 pandemic shutdowns of human research (LLWS n = 56, control n = 58). We observed significantly faster (p<.05) walking speed (mean change 0.08±0.02 m/s) after the 8-week program, as well as significantly greater improvements in the Short Physical Performance Battery (mean change 0.95±0.32) and the Activity Measure for Post Acute Care (mean change 2.1±0.8) withing the LLWS group (all p < 0.05). These observed increases were consistent with large clinically meaningful differences. Our study demonstrates that LLWS enabled statistically significant and clinically meaningful gains in mobility among middle aged and older adult Veterans with slow walking speed, justifying its efficacy as a treatment for mobility limitations. Separate analyses of this clinical trial will evaluate long term outcomes and be better powered to evaluate changes in the attributes LLWS targets.
