Hand-held dynamometers for measuring shoulder strength

Paper summary Rehab Prevention

This is a summary of the insights from 4 research papers relating to measuring certain types of shoulder strength with a hand-held dynamometer.

Hand-held dynamometers seem to be valid for measuring different types of shoulder strength

1) Eccentric strength of external rotators: Standardized eccentric rotator cuff strength can be tested and measured in the clinical setting with good-to-excellent reliability and validity using an HHD (original research paper)

2) Strength of internal & external rotation: HHD showed moderate to very strong correlations to the isokinetic testing (original research paper)

3) Strength of shoulder rotators: Very high correlation was found for shoulder rotator torque assessment between HHDs and IDs (original research paper)

4) Eccentric strength of shoulder abductors: the HHD and isokinetic dynamometer measurements were strongly correlated (original research paper)

➡️ Using an HDD to measure several types of shoulder strength seems to be a valid and reliable method that can be used for research and clinical purposes when an isokinetic dynamometer cannot be used.

❗ In the Hylyght platform, we have implemented prevention tests for a large variety of sports. Because of our collaborations with the University of Ghent and Brussels, we have a strong focus on evidence-based screening but we encourage our clients to blend in their own expertise.
