Abstract

Background: Spinal cord injury and stroke are neurological disorders that lead to aerobic deconditioning and increased likelihood of cardiovascular disease. Sessions of at least 20 minutes of moderate-to-vigorous intensity exercise is recommended but decreased mobility limits engagement in such exercise. The aim of the study was to assess whether individuals can achieve exercise recommendations with the assistance of an end-effector robot assisted gait trainer (E-RAGT).
Methods: We conducted an observational study during which participants were required to complete one exercise session on an E-RAGT. Heart rate, dyspnea, lower limb fatigue and enjoyment were monitored. Based on current guidelines, participants were considered to have reached exercise recommendations if they reached prespecified intensity thresholds for at least 20 minutes.
Results: Five people with spinal cord injury and ten people with stroke agreed to participate. Every participant was able to reach moderate-to-vigorous exercise intensity and 3 out of 5 participants with spinal cord injury and 4 out of 10 participants with stroke were able to maintain this intensity for at least 20 minutes. Overall, participants rated their session as very enjoyable with a median score of 4 out of 5 on a Likert Scale (IQR 3 to 4).
Discussion: Individuals with spinal cord injury or stroke who use an E-RAGT can reach moderate-to-vigorous exercise intensity, but not all are able to maintain this intensity of exercise according to disease-specific recommendations. Future research should explore the effectiveness of a training program using an E-RAGT.
