A study testing wearable passive back support suit and traditional lumbosacral orthosis in people with Back Pain and Exoskeleton Device, run by Samsung Medical Center at 1 site in South Korea.
Trial summary
The physical demands of patient transport, including lifting and transferring patients, are significant contributors to the high risk of musculoskeletal disorders. Previous studies have demonstrated that these workers frequently experience musculoskeletal pain. Read more about this study

About this study
The physical demands of patient transport, including lifting and transferring patients, are significant contributors to the high risk of musculoskeletal disorders. Previous studies have demonstrated that these workers frequently experience musculoskeletal pain. Although current prevention strategies primarily consist of passive education on posture, there is a clear need for more active, assistive methods. The emergence of wearable passive back support suits as a potential solution is noteworthy; however, robust clinical research on the effectiveness of these devices in real-world care giving environments is currently lacking.
The objective of this study is to investigate the effects of a wearable passive back support suit on reducing and preventing the incidence of back pain in patient transporters.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the Korean Oswestry Low Back Pain Disability Questionnaire(K-ODI) score (time frame: baseline, Week 2(after period 1), week 4(after washout) and week 6 (after period 2)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
