Overground Walking Program With Robotic Exoskeleton in Long-term Manual Wheelchair Users With Spinal Cord Injury

Spinal Cord Injuries Clinical Trial

Official title: Effects of an Overground Walking Program With Robotic Exoskeleton in Long-term Manual Wheelchair Users With a Chronic Spinal Cord Injury

Status Terminated

Clinical Trial Summary

Many individuals with a spinal cord injury (SCI) use a wheelchair as their primary mode of locomotion. The prolonged non-active sitting time associated to this mode of locomotion contributes to development or worsening of numerous adverse health effects affecting musculoskeletal, endocrino-metabolic and cardiorespiratory health. To counter this vicious circle, engaging in a walking program with a wearable robotic exoskeleton (WRE) is a promising physical activity intervention. This study aims to measure the effects of a WRE-assisted walking program on musculoskeletal, endocrino-metabolic and cardiorespiratory health.

Clinical Trial Description

Many individuals with a spinal cord injury (SCI) rely on manually propelled wheelchairs as their primary source of locomotion, leading to increased non-active sitting time, reduced physical activity and reduced lower extremity (L/E) weight bearing. This contributes to the development or worsening of complex and chronic secondary health problems, such as those affecting musculoskeletal (e.g., osteoporosis), endocrine-metabolic (e.g., hypertension, dyslipidemia, type 2 diabetes) and cardiorespiratory (e.g., poor aerobic fitness) health. Ultimately, these health problems may negatively affect functional capabilities and reduce quality of life. Preliminary evidence has shown that engaging in a walking program with a wearable robotic exoskeleton (WRE) is a promising intervention. In fact, WRE-assisted walking programs promote L/E mobility and weight bearing (a crucial stimulus for maintaining bone strength in individuals with SCI), while also soliciting the trunk and upper extremity muscles and cardiorespiratory system. This study aims to measure the effects of a WRE-assisted walking program on 1) bone strength, bone architecture and body composition, 2) endocrino-metabolic health profile and 3) aerobic capacity. Twenty (20) individuals with a chronic (> 18 months) SCI will complete 34 WRE-assisted training sessions (1 h/session) over a 16-week period (1-3 sessions/week). Training intensity will be progressed (i.e., total standing time, total number of steps taken) periodically to maintain a moderate-to-vigorous intensity (≥ 12/20 on the Borg Scale). All training sessions will be supervised by a certified physical therapist. Main outcomes will be measured one month prior to initiating the WRE-assisted walking program (T0), just before initiating the WRE-assisted walking program (T1), at the end of the WRE-assisted walking program (T2) and two months after the end of the WRE-assisted walking program (T3). Descriptive statistics will be used to report continuous and categorical variables. The alternative hypothesis, stipulating that a pre-versus-post difference exists, will be verified using Repeated Mesures ANOVAs or Freidman Tests. ;
