Comparing three trunk-assist exoskeletons and no assistance during lifting

Official title: Choosing a Trunk Assistance Exoskeleton: Issues of Cumulative Lumbar Loading, Muscle Fatigue, and Discomfort During Repetitive Lifting Tasks

Run by Topmed · NCT07084974 · Data updated 2026-11-12

This project will test three trunk-assist exoskeletons and no assistance in healthy French-speaking adults to see if they reduce back muscle fatigue and cumulative lumbar load during repeated lifting.

Is this trial a fit for you?

Likely a good fit

Ideal participants are healthy, French-speaking adults without recent back pain or trunk musculoskeletal conditions who can perform the required lifting rhythm and have BMI ≤35 kg/m².

Probably not a fit

People with recent or chronic back pain, scoliosis, recent trunk surgery or musculoskeletal injury, neurological damage, BMI over 35, or who cannot safely perform the lifting task are unlikely to benefit or be eligible.

What this trial studies

Healthy adult volunteers who can communicate in French will be fitted with three different trunk-assist exoskeletons and will also perform a lifting session without assistance. After an initial adjustment and practice session, participants will perform a standardized lifting task consisting of four 20-minute blocks in separate sessions for each device and a no-assist session. Researchers will measure cumulative lumbar load, trunk extensor muscular fatigue, and participant comfort during the tasks. Each participant will serve as their own comparison to evaluate differences between devices and no assistance.

Why it matters

Potential benefit: If effective, these exoskeletons could lower back muscle fatigue and spinal load during lifting, potentially reducing work-related low back injuries.

How similar studies have gone: Previous lab studies of trunk and back-support exoskeletons have reported reductions in lumbar load and muscle activity in some tasks, though results depend on device design and work conditions.
