A functional movement screen (FMS) is a systematic evaluation that assesses an individual's movement patterns to identify limitations or asymmetries. It's typically used in fitness and rehabilitation settings to determine potential risks for injury and to guide personalized exercise programs. The screening evaluates key movements like squatting, lunging, and reaching. By pinpointing areas needing improvement, trainers and therapists can design interventions aimed at enhancing mobility, strength, and overall functionality, ultimately promoting better physical performance.
