Exoskeleton and Spinal Cord Injury (EXTra-SCI)

February 1, 2022 updated by: Ashraf Gorgey, McGuire Research Institute

Exoskeleton Training After Spinal Cord Injury

The purpose of the current study is to investigate the effects of powered exoskeleton (EKSO) on cardiovascular performance as measured by resting blood pressure and heart rate, peak oxygen consumption during walking, energy expenditure, whole and regional body composition assessments. The effects of exoskeleton training on walking kinematics including stand-up time, walking time, distance covered and speed of walking will also be evaluated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Powered exoskeletons using robotic suits have recently been introduced for the rehabilitation of persons with spinal cord injury (SCI). Exoskeletons offer a unique opportunity for persons with SCI to experience standing and walking at a low metabolic cost. Evidence suggested that exoskeleton assisted walking can decrease spasticity and improve bowel movement. Training may also improve the level of physical activity as well as psychological parameters that are likely to interfere with rehabilitation outcomes. Previous studies reported that a frequency of 2-3 times per week or more for 1-2 hours may be beneficial in the rehabilitation of persons with SCI. Using exoskeletal-assisted walking to improve the level of physical activity may be appealing to persons with SCI.

Exoskeleton training for 12 weeks may enhance energy expenditure, parameters of physical activity and result only on modest effects on both cardiovascular and body composition parameters. In other words, persons with tetraplegia may have greater cardiovascular and body composition adaptations compared to persons with paraplegia. Twenty subjects will participate in a powered exoskeleton (EKSO) for one or twice a week for 12 weeks. The program will involve walking with the robotic suits for 1 hour for persons with complete (n=10) and persons with incomplete (n=10) SCI.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
