OBJECTIVE: Comparison of the accuracy of surface electromyogram for back muscle endurance assessment with two different tests. DESIGN: Test-retest measurements in 16 healthy volunteers on two separate occasions for each test under controlled conditions. BACKGROUND: Back muscle endurance is considered important in low back pain rehabilitation. Reliability of paraspinal muscle endurance assessment is a pre-requisite for accurate and meaningful clinical applications of the technique. METHODS: All participants performed each test twice. A direct comparison was made between two popular fatigue testing methods, the modified Biering-Sørensen and a 60% maximum voluntary isometric contraction in the upright position during which time fatigue was assessed from the electromyogram spectral and amplitude analysis. RESULTS: Reproducibility of initial median frequency was excellent for both tests. Normalised median frequency slope values were more reliable with the 60% maximum voluntary contraction upright test. The clinical applicability of these measures in detecting significant differences after patient rehabilitation is recommended. Root mean square had very large between-day error for both tests.
