Key parameters of musculoskeletal function are strength, endurance, and range of motion. In a current study of men and women ages 60+ (N=20), we have a Musculoskeletal Function Evaluation (MFE) that tests isometric strength in the whole body (19 locations; unilateral; 3 trials each); the protocol also has isometric endurance and range of motion tests. A strength test lasts 5 seconds (Nm recorded every 1/10 second), and time to peak. A specially-designed partable unit (called the MFE Chair) was used to obtain the strength data in the subject’s own home. We describe technical aspects (hardware, electronics, software) of the MFE Chair. Its generic features make it suitable for other studies of strength in older persons (relationships across locations), (2) reliability (relationships across trials), and (3) force trajectories (plots of 1/10-sec. readings). (1) Factor analyses show unidimensional structure (high relationships among upper extremity tests, and among lower extremity tests) is almost as good. So a person’s strength can be summarised either way (whole body or upper and lower). (2) Reliability statistics show that two trials suffice to give sturdy measurement of strength in a given location. There is some evindence of a training effect for trial 1 but not enough to drop it; so trials 1 and 2 can be averaged. (Peak and average max produce the same results for both (I) and (2). (3) Plots for typical subjects show very steady force trajectories after the peak value is attained (older subjects maintain their force outputs), and also similar patterns across trials (subjects approach a test the same way for every trial). Conclusions: Substantively, we find that strength has high congruence across body areas. Methodologically, we find that a detailed strength protocol can have fewer tests than ours did.The text summarises the project design and its results to strength profiles of older persons.
