Overview
The SFMA (Selective Functional Movement Assessment) squat is one of seven fundamental movement patterns assessed in individuals experiencing musculoskeletal pain. Unlike a generic squat, the SFMA squat is not just about performing the movement, but about observing its quality and identifying underlying dysfunction. The SFMA squat involves standing with feet shoulder-width apart, toes facing forward, and arms extended forward with palms facing down. The individual then slowly descends as deep as possible into a squat position, aiming to keep heels on the floor, and head and chest facing forward. At the bottom, swing the arms down and back while keeping elbows extended, bringing your hands as close to the floor as possible. Then swing the arms back forward and stand back up to complete the movement. The assessment is highly qualitative, with trained clinicians often observing for specific deviations and compensations. The goal is to determine if any limitations are due to:- Mobility issues: Problems with joint range of motion (e.g., tight ankles, hips, or thoracic spine) or tissue extensibility (e.g., tight muscles).
- Stability/motor control issues: Difficulties with neuromuscular coordination, muscle activation, or maintaining control throughout the movement.
Instructions
Stand with feet shoulder-width apart, toes facing forward, arms extended forward with palms down. Slowly descend as deep as possible into a squat, heels on the floor, head and chest facing forward. At the bottom, swing the arms down and back (elbows extended), bringing the hands as close to the floor as possible, then swing the arms forward and stand back up to complete one repetition.Example Videos
