PMID 37248939WHAT IT FOUND
Individuals with brachial plexus injury had lower two-handed functional capacity than healthy controls but similar one-handed capacity on their unaffected side.
They exerted the same heart rate and perceived effort, meaning they are not working less hard, just with less capacity.
Key findings
01Two-handed functional capacity was significantly lower in individuals with BPI compared to healthy controls, with medium to large effect sizes.
02One-handed functional capacity on the unaffected side was similar to that of healthy controls, despite the lower two-handed capacity.
03Perceived loads and heart rate increases were similar between groups, indicating equivalent physical effort despite lower performance in two-handed tasks.

What it does not show
Small sample size (23 BPI, 20 controls) limits generalizability. Low participation rate (23 of 93 invited) introduces potential selection bias. Hand function classification used a non-validated question and physical exam. The study included both adult and obstetric BPI, which may differ in adaptation. No correction for multiple testing was applied, increasing the chance of false positives. Cross-sectional design cannot determine causality or long-term outcomes.
Declared interests
The authors declare that they have no conflict of interest.
The easy way to misread this
Do not interpret similar one-handed capacity on the unaffected side as evidence that the patient can safely handle high-load work without adaptation. The lower two-handed capacity and compensatory strategies suggest increased risk for musculoskeletal complaints in the unaffected limb, neck, and back, even if test scores appear normal.
