High vs Low-frequency of High-intensity Training in Chronic Stroke
Indiana University
Summary
The purpose of this pilot study is to investigate the potential role of training frequency on locomotor outcomes following high-intensity gait training and provision of a home walking program.
Description
This study will utilize a 2 arm randomized trial to investigate potential differences in locomotor and community outcomes following 18 visits of high-intensity gait training provided over 6 weeks (high frequency) or 12 weeks (low frequency). Following confirmation of eligibility and baseline testing, individuals will be randomized to either high or low frequency of training and complete subsequent testing at 6 weeks, 12 weeks, and 24 weeks.

Interventions
- Otherhigh-intensity gait training
Individuals will perform up to 40 minutes of walking practice during 60 minute sessions while targeting heart rates of at least 70% heart rate reserve.
- BehavioralPhysical activity coaching
Individuals will receive feedback on the minutes of walking activity performed on non-training days and provided coaching strategies to increase this metric.
