Normative Database for Trunk Range of Motion, Strength, Velocity, and Endurance with the Isostation B-200 Lumbar Dynamometer

A review of related literature and trends was used to develop a protocol for testing range of motion, isometric strength, velocity, endurance, and consistency of effort in the low-back pain (LBP) population by the use of the triaxial, Isostation B-200 Lumbar Dynamometer. Eighty-five men and 83 women with no history of LBP for the past 6 months volunteered for the study. Relationships between demographic and test measures were calculated by the use of the Pearson r correlation analysis and ANOVA. Body weight, age, and gender all showed strong (P less than .001), positive relationships to various test measures. The normative database is reported in terms of descriptive statistics allowing comparison of future test results within the normal distribution and corrected for significant demographic features.
