Check if pain is elicited during these provocation tests. Pain = automatic FMS score of 0.
FMS Score Interpretation Reference
| Score | Injury Risk | Statistical Risk | Recommendation |
|---|---|---|---|
| 15 – 21 | Low Risk | Baseline injury rate | Continue training; address any asymmetries |
| ≤ 14 | High Risk | 3.5× higher injury rate | Corrective exercise priority before training loads |
| Any asymmetry | Flag | Elevated regardless of total | Address L/R imbalance before increasing intensity |
| Any score of 1 | Flag | Movement dysfunction present | Corrective programming for that pattern mandatory |
| 0 (Pain) | Refer | FMS score invalid | Clinical diagnosis required before any exercise |
What is the Functional Movement Screen?
The Functional Movement Screen (FMS) is a 7-test movement quality assessment system developed by Gray Cook and Lee Burton (2006) to identify movement pattern dysfunction and injury risk in physically active individuals and athletes. Unlike traditional strength or flexibility tests that assess isolated structures, the FMS evaluates fundamental movement patterns — the foundational movement skills required for safe and efficient physical performance. It is used by professional sports organizations, military personnel screening programs, corporate wellness programs, and physical therapy clinics worldwide.
The 14-Point Injury Risk Threshold
The most important clinical finding from FMS research is the 14-point threshold. In the landmark study by Kiesel, Plisky, and Voight (2007) examining professional American football players, athletes scoring 14 or below on the FMS were 3.5 times more likely to sustain a non-contact musculoskeletal injury during the competitive season. This finding has been replicated across multiple sports and populations, establishing 14 as the critical screening cutoff for injury risk stratification.
The 7 FMS Tests Explained
- Deep Squat: Challenges bilateral, symmetric mobility and stability of the hips, knees, and ankles combined with thoracic spine extension and shoulder flexion. The dowel is held overhead to assess upper extremity mobility simultaneously.
- Hurdle Step: Challenges the mechanics of stepping — requires single-leg stance stability on the stance leg while the hurdle leg demonstrates adequate hip flexor and hamstring mobility. Assesses stride mechanics.
- In-Line Lunge: Challenges thoracic spine rotation, hip mobility, quad flexibility, and multi-planar knee stability during a lunge pattern with a dowel held behind the back.
- Shoulder Mobility: Assesses bilateral shoulder range of motion — internal rotation, external rotation, adduction, and abduction — simultaneously with thoracic extension and scapular mobility.
- Active Straight Leg Raise: Assesses the ability to dissociate the lower extremities while maintaining pelvic stability and core control. Tests hamstring and calf flexibility with opposite hip in extension.
- Trunk Stability Push-Up: Assesses the ability to stabilize the spine in the sagittal plane during a closed-chain upper body movement. Detects poor reflexive trunk stabilization patterns.
- Rotary Stability: Assesses multi-planar trunk stability during simultaneous upper and lower extremity movement. The most demanding FMS pattern — requires complex neuromuscular coordination.
FMS Scoring Logic and the Pain Rule
The FMS uses a 4-point ordinal scale:
- Score 3 — Performs perfectly: Movement completed without compensation, equipment, or modification. Full pattern quality achieved.
- Score 2 — Performs with compensation: Movement completed but with detectable compensation, modified position, or reduced range. Not dysfunctional but not optimal.
- Score 1 — Unable to perform: Cannot complete the movement pattern even with compensation, or loses balance. Indicates movement dysfunction requiring corrective intervention.
- Score 0 / P — Pain: Any pain reported at any point during the movement. The entire FMS score defaults to 0 regardless of other items. Pain is a medical indicator that cannot be addressed with corrective exercise — clinical diagnosis is mandatory first.
Asymmetry — The Hidden Injury Risk
A critical and often underappreciated finding on the FMS is asymmetry — scoring differently on the left versus right side for bilateral tests (Hurdle Step, In-Line Lunge, Shoulder Mobility, Active Straight Leg Raise, Rotary Stability). Research shows that asymmetry independently predicts injury risk regardless of total score. An athlete scoring 16 with a left-right asymmetry is at higher injury risk than an athlete scoring 14 without asymmetry. Always address asymmetries before increasing training volume or intensity.
Clinical Applications
- Pre-participation screening: Baseline assessment for athletes before competitive seasons
- Return-to-sport clearance: Verifying movement quality restoration after injury
- Corporate wellness: Identifying movement dysfunction in sedentary workers before exercise programs
- Military fitness: Used by US armed forces for physical readiness screening
- Rehabilitation discharge: Confirming readiness for independent exercise after PT
FMS vs Other Movement Assessments
- vs Y-Balance Test: Y-Balance specifically tests dynamic balance and reach in a single-leg stance; FMS tests 7 fundamental movement patterns. Both are commonly used together in injury prevention programs.
- vs Manual Muscle Testing (MMT): MMT assesses isolated muscle strength; FMS assesses integrated movement pattern quality. FMS is more functional and predictive of injury risk.
- vs Selective Functional Movement Assessment (SFMA): SFMA is the clinical version of FMS for patients with pain — it guides diagnosis of movement dysfunction. FMS is for healthy, pain-free screening populations.
