About this study
Official title: Effects of Gait Training for Individuals With Paraplegia Using H-MEX Exoskeleton: A Pilot Study
This study evaluates the feasibility and effects of H-MEX powered exoskeleton in individuals with paraplegia as a result of spinal cord injury.
Read the detailed description
Participants with paraplegia will attend gait training using H-MEX powered exoskeleton 3 times a week for 10 weeks.
The aim of this study is to assess the impact of gait training using H-MEX powered exoskeleton on walking ability, gait analysis, medical examination, body composition, functional evaluation, laboratory findings, quality of life, and subjective experience in individuals with paraplegia.
Participants will be evaluated before, during, and after training.

Types and number of the adverse events both serious and non-serious events during training sessions.
Measured: 0-14 weeks
Secondary outcomes (10)
Changes in 6 minute walking test with H-mex exoskeleton

Changes in timed up and go test with H-mex exoskeleton
Time that a participants takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down will be measured.
Measured: Initial evaluation, mid-evaluation (after 5 weeks of training), and Final evaluation (after 10 weeks of training)
Changes in Berg balance test with H-mex exoskeleton
Balance will be evaluated by using Berg balance test which is 14-item test designed to assess balance (score range: 0-56, higher values represent a better outcome).
Measured: Initial evaluation, mid-evaluation (after 5 weeks of training), and Final evaluation (after 10 weeks of training)
Changes in body composition
Body composition will be assessed by using bioelectric impedence analysis.
Measured: Initial evaluation, mid-evaluation (after 5 weeks of training), and Final evaluation (after 10 weeks of training)
Changes in oxygen uptake during gait training with H-mex exoskeleton
Average and peak oxygen uptake will be measured with participants during gait training.
Measured: Initial evaluation, mid-evaluation (after 5 weeks of training), and Final evaluation (after 10 weeks of training)
Changes in heart rate during gait training with H-mex exoskeleton
Average and peak heart rate will be measured with participants during gait training.
Measured: Initial evaluation, mid-evaluation (after 5 weeks of training), and Final evaluation (after 10 weeks of training)
Changes in bone mineral density
Bone mineral density will be measured at hip and spine by dual energy X-ray absorptiometry.
Measured: Initial evaluation and Final evaluation (after 10 weeks of training)
Changes in colonic transit time
Colonic mobility will be assessed by colonic transit time.
Measured: Initial evaluation and Final evaluation (after 10 weeks of training)
Changes in quality of life: Short-Form 36-Item Health Survey version 2
Quality of life will be assessed by Short-Form 36-Item Health Survey version 2 (total score range: 0-100, higher values represent a better outcome).
Measured: Initial evaluation and Final evaluation (after 10 weeks of training)
Changes in fear for fall
Fear for fall will be assessed by fall efficacy scale which is 16-item test (score range: 16-64, higher values represent a worse outcome).
Measured: Initial evaluation and Final evaluation (after 10 weeks of training)

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04055610, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
