A technique used to test the strength (or lack thereof) of muscles, and the impact that has on bodily movement and function. Imbalances, weakness, and dysfunction can all contribute to chronic pain or movement impairment. The body is designed to work as a system of systems, and one poorly functioning system can cause a chain reaction throughout the rest of the body. By testing common movement patterns, joint actions, and select muscle groups, we can pinpoint the problem areas and determine the best course of treatment.
