Since its inception, isokinetic dynamometry has provided unique insights into muscle function evaluations for human performance and rehabilitation, thus they are commonly utilized in training and rehabilitative centers, as well as in exercise science laboratories. Because such devices are clinically relevant in the diagnosis of musculoskeletal health and assessment of athletic prowess, it is important that isokinetic dynamometry yield accurate performance values. Assuming no change in a person's exercise performance capabilities, multiple isokinetic dynamometry bouts should elicit data values that are reproducible. Variability that results from test-retest research designs, and undermines data reliability, may be subdivided into mechanical and physiological sources of measurement error. The following paper offers a review of literature pertaining to the reproducibility of isokinetic dynamometry data. The literature is subdivided and categorizes a variety of test-retest study design papers according to the musculoskeletal segment under examination. While most papers describe their data reproducibility results as acceptable or better, a consistent outcome from the literature is greater variability at higher angular velocities. For isokinetic exercise, this is perhaps its most pressing concern, and future recommendation, that should be addressed with the advent of newer dynamometer models. Such improvements will continue to make isokinetic dynamometry a modality that offers the most unique insights on muscle function evaluations for athletic performance and clinical rehabilitation.
