Asymmetric Locomotor Training in the Elderly to Restore Physical Function

Disability Clinical Trial

Official title: Asymmetric Locomotor Training in the Elderly to Restore Physical Function

Status Withdrawn

Clinical Trial Summary

Innovative advances in rehabilitation technology have created a split-belt treadmill capable of providing a much needed intervention aimed at limiting mobility disability. When desynchronized, the split-belt treadmill imposes demands on each leg such that the central nervous system must adapt to the challenge. Based on preliminary data from our lab utilizing the split-belt treadmill, the investigators hypothesize this intervention can challenge the locomotor processes required for safe, efficient gait while concurrently providing an aerobic stimulus will produce favorable changes in physical function in older adults at risk for mobility disability.

Clinical Trial Description

For this pilot study the investigators will enroll 20 sedentary older adults at risk for disability (usual gait speed ≤ 1.0 m/s). Participants will be assigned to one of two 12-week interventions. Therefore the final training pool will consist of 10 split-belt participants and 10 traditional treadmill participants. Aim 1 will test the hypothesis that compared with a traditional treadmill intervention a split-belt treadmill intervention will result in improved mobility, as measure by 400 meter walk time, as well self reported physical function/disability as measured by the Pepper Assessment Tool for Disability. Aim 2 will test the hypothesis that compared with a traditional treadmill intervention a split-belt treadmill intervention will results in improved gait variability. To date, no experimental study has evaluated these propositions in a controlled trial testing the effects of split-belt training in older adults at risk for disability. ;
