Contextual overview
The 5-STS test measured with FEMD provides a robust benchmark for lower-body muscle power. With ICC values reaching 1.00 for certain metrics, clinicians can confidently use this setup to monitor functional improvements in young healthy populations.
Original publication abstract
The study by Jerez-Mayorga et al. (2021) evaluates the test-retest reliability of using a functional electromechanical dynamometer (FEMD) to measure strength and velocity during the five-repetition sit-to-stand (5-STS) test. Results showed high to very high reliability (ICC 0.95–1.00) across different incremental loads (5, 10, and 15 kg), indicating that FEMD is a precise instrument for assessing lower-body functional performance.
