Abstract
The study by Cerda-Vega et al. (2018) evaluated the validity and reliability of using an FEMD to measure hip abductor strength across different positions. While side-lying produced the highest force, the supine position combined with allometric normalization was found to be the most consistent and reliable for assessment.
For the most precise monitoring of hip strength, practitioners should prefer supine testing with allometric scaling. This research helps standardize assessment protocols, ensuring that differences in strength are due to performance rather than body size or positioning.
