Shoulder immobilization with a sling and how it affects shoulder biomechanics
Official title: The Impact of Shoulder Immobilization by Orthoses on Human Joint Biomechanics and Inter-joint Coordination
Run by National Taiwan University Hospital · NCT07659054 · Data updated 2026-11-12
This study tests whether wearing a shoulder sling changes how the shoulder moves and how the body balances, in people with clavicle fractures, rotator cuff injuries, and healthy controls.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 20–65 with mid-shaft clavicle fractures or acute shoulder rotator injuries, and healthy controls matched by age, height, and weight.
✕Probably not a fit
Participants without the specified shoulder injuries or those unable to tolerate a shoulder sling may not experience direct benefits.

What this trial studies
This interventional study examines the biomechanical impact of shoulder immobilization using a sling on joint coordination and movement. It analyzes how different immobilization positions influence upper-limb mechanics and overall balance, using motion analysis techniques to quantify changes. Participants include adults with mid-shaft clavicle fractures or acute shoulder rotator injuries, as well as age- and size-matched healthy controls. The investigation aims to understand how immobilization may alter reciprocal arm swing, gait and balance during daily activities. Data from this work could inform rehabilitation strategies and device selection for improved stability and recovery.
Why it matters
Potential benefit: If successful, results may guide clinicians in choosing the most appropriate shoulder orthosis to optimize recovery while preserving balance and safe movement.
How similar studies have gone: Previous research has shown that upper-limb immobilization can affect movement and balance, but this study adds detailed biomechanical analysis in this context.
