Trial Outcomes & Findings for A Novel Strategy to Decrease Fall Incidence Post-Stroke (NCT NCT02688777)

NCT ID: NCT02688777

Last Updated: 2023-11-24

Results Overview

Fall incidence will be monitored using the international standards for defining and reporting falls,60 including the following definition for a fall: "A person has a fall if they end up on the ground or floor when they did not expect to. Most often a fall starts while a person is on their feet, but a fall could also start from a chair or bed. If a person ends up on the ground, either on their knees, their belly, their side, their bottom, or their back, they have had a fall." This explanation will be provided to participants and caregivers and printed on monthly calendars issued at randomization. The number of falls will be recorded on a monthly basis and then added across months to determine the number of recorded falls between baseline and 1-year post-stroke.

Immediate Backward Walking Training
Individuals will participate in 18 sessions of Backward Walking training immediately following baseline assessment. Backward Walking Training (BWTraining): Backward Walking Training will occur both on a treadmill and overground. In brief, Backward Walking Training (BWTraining) will consist of 20-30 minutes of step training with a Body Weight Support and Treadmill system (BWST), rest periods provided as warranted, with manual assistance provided by trainers, followed by 15 minutes of overground gait training. A 20-30 min period of actual stepping is the goal for the intervention sessions on the treadmill with rest periods as needed. Each training session may last up to 1 hour and 30 minutes including time for warm-up, stretching, and cool down. Participants will be fitted with a harness around their hips and torso, which will be attached to an overhead support system directly above the treadmill. From a stationary position, the treadmill belt will gradually be increased in speed with intervention trainers assisting participant to step backward with their paretic leg, their non-paretic leg (if needed) and at the hips for weight-shift.

In brief, BWTraining will consist of 20-30 minutes of step training with a Body Weight Support and Treadmill system (BWST), rest periods provided as warranted, with manual assistance provided by trainers, followed by 15 minutes of overground gait training. A 20-30 min period of actual stepping is the goal for the intervention sessions on the treadmill with rest periods as needed. Each training session may last up to 1 hour and 30 minutes including time for warm-up, stretching, and cool down. Participants will be fitted with a harness around their hips and torso, which will be attached to an overhead support system directly above the treadmill. From a stationary position, the treadmill belt will gradually be increased in speed with intervention trainers assisting participant to step backward with their paretic leg, their non-paretic leg (if needed) and at the hips for weight-shift.
