Robotic devices may be used to help the gait and balance of individuals with Spinal Cord Injury (SCI). However, as such devices may allow individuals to engage in physical activity in an upright position, there may be significant benefit on the vascular health of patients with SCI. This study will assess the effect of a robotic-assisted gait-training (exoskeleton) program on central and peripheral hemodynamic markers in people with SCI.

Individuals with spinal cord injury (SCI) have an accelerated trajectory of aging in the cardiovascular system compared with same-age individuals in the general population,and accordingly, have a higher rate of cardiovascular mortality. For example, SCI is significantly associated with an increased risk of heart disease (odds ratio = 2.72) and stroke (odds ratio = 3.72).This is at least partially attributed to their impaired blood pressure regulation as a consequence of the autonomic nervous system dysfunction, physical inactivity and increased sedentary time. As such, there is a pressing need to identify practical strategies for increasing physical activity and decreasing sedentary time. Robotic-assisted gait training (RGT) is used in the rehabilitation of patients with SCI, although individual access is often limited and infrequent. Task-specific stepping practice enhances the afferent feedback associated with normal locomotion and can induce plasticity in the involved motor centers. As RGT enables practitioners to increase the intensity and total duration of physical activity whilst maintaining a physiological gait pattern, there may be significant benefit for people with SCI to manage their risk of cardiovascular disease (CVD). This may be evident if an individual with SCI has regular and continued access to such technology. However, there is a paucity of research which has considered the vascular benefit of implementing robotic-assisted training for people with SCI as most research focuses on outcome measures such as gait velocity, gait distance, leg strength, balance and spasticity.Further, while this technology may be practical in terms of application, the cost is currently prohibitive. Thus, prior to advocating resource intensive longitudinal randomized control trials, there's a need for short-term trials using established measures of cardiovascular health. The purpose of this study is to assess the effect of a RGT (exoskeleton) program on central and peripheral hemodynamic markers in people with SCI.
