The Functional Movement Screen The Functional Movement Screen (FMS) is a screening tool used to evaluate seven fundamental movement patterns in individuals with no current pain complaint or musculoskeletal injury. The FMS is not intended to diagnose orthopedic problems but rather to demonstrate opportunities for improved movement in individuals. The screen is designed to place an individual in extreme positions where movement deficits become noticeable if appropriate stability and mobility are not used. Even though individuals are performing an activity or sport at a high level, it has been observed that many of these same individuals are limited in fundamental movement. This leads to the use of compensatory movements in order to achieve or maintain the level of performance needed for the activity. The inefficient use of compensation during movement will lead to poor biomechanics that limit gains in performance and reduces the body’s ability to remain adaptable and durable against the risks of being involved in the activity or sport.
