[Abduction/external rotation immobilization after primary traumatic anterior shoulder dislocation: which ortheses are...

Area of Science:

• Orthopedic biomechanics
• Rehabilitation engineering

Background:

• Shoulder immobilization in 60° external rotation and 30° abduction aids healing after anterior dislocation.
• Evaluating commercial shoulder braces for functionality and comfort is crucial for patient recovery.

Purpose of the Study:

• To assess the functionality and comfort of four commercially available shoulder braces.
• Identify potential issues and user-reported problems associated with each brace.

Main Methods:

• Ten healthy subjects (6 female, 4 male, avg. age 23) tested four braces: Omo Immobil, Quadrat, MP Airplane Axilla, and ARC XR.
• Subjects performed simulated activities of daily living (ADLs), rating comfort, difficulty, and pain.
• Brace position stability was verified via digital photography and active repositioning tests.

Main Results:

• MP Airplane Axilla and ARC XR braces were rated significantly more comfortable (p < 0.05) and easier to don/doff.
• Omo Immobil and Quadrat braces were associated with statistically significant pain.
• No significant differences in maintaining the desired position were found between braces, but braces 1 and 2 allowed more unwanted arm rotation.

Conclusions:

• Shoulder braces positioned in the axilla or offering jointless stabilization are superior for external rotation/abduction immobilization.
• Braces incorporating an additional sling on the opposite shoulder may enhance positional support and comfort.
