A stress test on a treadmill, hooked up to monitors, indicates how your heart functions when challenged. Repeated movement testing, which I perform and prescribe, indicates how your joints, muscles, and nerves function when challenged. Pictures tell us how things are at rest but not how they behave. And orthopedic special tests (OST) tell us how things are with a static test or with one movement. Barring a major structural problem, most problems are functional - and require dynamic testing (repeated movement testing) to arrive at a diagnosis. Repeated movement testing is one of the hallmarks of the McKenzie method.
Repeated movement testing is exactly what it sounds like. After I get a verbal history and note physical baselines such as range of motion, strength, and nerve tension, I choose a movement to be performed repeatedly and then assess the effect on symptoms and the baselines from the physical exam. The repeated movement I choose to test is based on several factors. An example of a repeated movement would be performing 10 shoulder internal rotations or 10 lumbar extensions.
