Movement Screening and Corrective Exercise: Finding Weak Links Before They Break

Every member has movement limitations. Some are obvious — the lifter who cannot hit parallel in a squat, the pitcher whose shoulder mobility is visibly asymmetric. Others are subtle and only reveal themselves under fatigue or load, which is exactly when injuries happen.

Movement screening is the practice of systematically testing fundamental movement patterns to identify limitations, asymmetries, and pain before they become injuries. The most widely used system is the Functional Movement Screen (FMS), developed by Gray Cook and Lee Burton in the 1990s.

The FMS: Seven Tests, One Score

The FMS evaluates seven fundamental movement patterns, each scored 0-3:

1. Deep Squat: Tests bilateral mobility of the hips, knees, and ankles, plus thoracic spine extension and shoulder mobility. The member holds a dowel overhead and squats as deep as possible.

2. Hurdle Step: Tests single-leg stance stability and hip mobility. The member steps over a hurdle set at tibial tuberosity height while maintaining a tall posture.

3. In-Line Lunge: Tests hip and ankle mobility in a split stance, plus trunk stability. Scored left and right — the lower score counts.

4. Shoulder Mobility: Tests bilateral shoulder range of motion. The member reaches one hand over the shoulder and one behind the back. The distance between fists determines the score.

5. Active Straight-Leg Raise: Tests hamstring flexibility and hip mobility while maintaining a stable pelvis. Scored left and right.

6. Trunk Stability Push-Up: Tests core stability during a push-up movement. Males must complete a rep with thumbs at forehead level; females at chin level.

7. Rotary Stability: Tests multi-plane trunk stability. The member performs a bird-dog pattern from quadruped position.

Each test is scored 0-3:

• 3: Performs the movement correctly without compensation
• 2: Performs the movement with compensatory patterns
• 1: Cannot perform the movement pattern at all
• 0: Pain during the movement (automatic referral)

The composite score is out of 21. Research by Kiesel et al. (2007) found that professional football players with a composite score of 14 or below were significantly more likely to sustain a serious injury during the season.

Asymmetries Matter

Bilateral tests (hurdle step, in-line lunge, shoulder mobility, active straight-leg raise, rotary stability) are scored for both sides. When the left and right scores differ by more than one point, it flags an asymmetry that increases injury risk.

A right shoulder mobility score of 3 and a left score of 1 does not just mean the left shoulder is tight — it means the member will compensate in overhead movements, shifting load to the right side and creating an overuse pattern. Addressing the asymmetry before it becomes a problem is the entire point of screening.

Corrective Exercise: Targeted Intervention

The value of the FMS is not the score itself — it is what you do with it. Each movement pattern maps to specific corrective exercises:

Deep Squat limitations → Ankle mobility drills (wall ankle rocks, banded dorsiflexion), hip flexor stretches, goblet squat holds, thoracic spine foam rolling

Shoulder Mobility limitations → Sleeper stretches, cross-body stretches, wall slides, band pull-aparts, external rotation strengthening

Active Straight-Leg Raise limitations → Hamstring contract-relax stretching, 90/90 hip switches, single-leg deadlift patterning

Trunk Stability limitations → Dead bugs, Pallof presses, plank progressions, anti-rotation movements

Rotary Stability limitations → Bird-dogs, bear crawls, half-kneeling chops and lifts

The corrective exercise prescription should be specific, brief (5-10 minutes), and performed consistently — typically as part of the warm-up before training sessions.

When to Screen

• Baseline: Every new member should be screened during onboarding. This establishes their movement profile and identifies immediate priorities.
• Post-injury: After rehabilitation, re-screen to verify that movement quality has been restored before returning to full training.
• Quarterly: Re-screen every 3-4 months to track improvements and catch new limitations that develop from training adaptations.

Implementing at Scale

Screening one member takes 10-15 minutes. Screening a roster of 40 takes a full day. This is where digital tools make a difference. Calsanova’s movement screening tool allows coaches to score each test in real time, automatically flags asymmetries, calculates composite scores, stores assessment history, and generates corrective exercise recommendations based on the results.

For S&C coaches managing large rosters, the ability to see every member’s movement quality profile on a single dashboard — and track changes over time — transforms screening from a one-time event into an ongoing injury prevention system.

Movement quality is the foundation that training is built on. If the foundation has cracks, the structure will eventually fail. Screen first. Correct the patterns. Then load them.
