Overview
The purpose of this study is to see if it's possible to reach high cardiovascular intensity training parameters (exercise at a rate that elevates heart rate to the level recommended for improving strength and endurance) while walking in a wearable robotic exoskeleton. This study will also evaluate if exercising at high intensity will lead to improvement in walking ability. Participants in this study will be asked to attend 5 walking training sessions using Ekso exoskeleton. There will be two additional sessions, one before and one after the five training sessions. At these two sessions, study participants will be asked to participate in seated balance, walking speed and endurance tests and breathing assessments.
Description
The purpose of this study is to determine the feasibility and potential efficacy to implement high cardiovascular intensity training parameters (70-80% heart rate reserve) with the use of overground wearable robotic exoskeletons in an inpatient rehabilitation setting for locomotor recovery.
The second aim is to investigate the potential functional improvements in gait after receiving high-intensity locomotor training with an overground exoskeleton, as measured on the 10-meter walk test and six-minute walk test.
