Movement Screens and Posture

Key Takeaways Explain This Topic AI

Movement screens identify dysfunction patterns before loading clients with resistance programs.

Overhead squat assessment reveals ankle, knee, hip, and shoulder mobility/stability compensations.

Upper crossed syndrome (forward head, rounded shoulders) and lower crossed syndrome (anterior pelvic tilt) are common postural patterns.

Corrective exercise follows inhibit-lengthen-activate-integrate (ILAI) or similar progressions.

Screens inform exercise selection—they do not diagnose medical pathology.

Last updated: September 2026

Quick Answer: Movement screens (overhead squat, single-leg squat, gait observation) reveal compensations like knee valgus or excessive forward lean. Use findings to regress exercises and add correctives—not to diagnose injuries.

Movement Screens and Posture

Movement screening bridges assessment and program design . ISSA CPT items present observation findings and ask which muscle is likely underactive or which exercise is the best initial correction.

Why Screen Before Load?

Loading dysfunctional patterns cements compensations and raises injury risk. Ten-minute screens save months of setbacks. Screens are not diagnostic —they flag referral needs (pain, neurological signs).

Overhead Squat Assessment (OHSA)

Client squats with arms overhead, feet shoulder-width, 5 reps observed anterior and lateral.

  • Observation Possible Implication
  • Heels rise Ankle dorsiflexion restriction
  • Knees cave inward Weak gluteus medius, tight adductors
  • Excessive forward trunk lean Hip flexor tightness, weak glutes, ankle limitation
  • Arms fall forward Lat/thoracic mobility restriction, weak lower traps
  • Low-back arches excessively Hip flexor tightness, weak core
  • Single-Leg Squat / Lunge Screen

Assesses dynamic stability . Pelvic drop (Trendelenburg), knee medial displacement, and trunk lateral flexion indicate hip abductor and core deficits.

Static Postural Observations

Upper crossed syndrome (Janda): forward head, protracted scapulae, internally rotated humeri. Tight: upper traps, levator scap, pecs. Weak: deep cervical flexors, lower traps, serratus anterior.

Lower crossed syndrome: anterior pelvic tilt, lumbar hyperlordosis. Tight: hip flexors, lumbar erectors. Weak: glutes, abdominals.

  • Corrective Exercise Framework
  • Inhibit overactive tissue (foam roll—modest evidence but common practice)
  • Lengthen (static stretch 30+ sec)
  • Activate underactive muscles (isolated activation sets)
  • Integrate into functional patterns (band-resisted squat)

Example for knee valgus: roll adductors → stretch → clamshells/side steps → banded squats.

Worked Scenario: OHSA Findings

Client shows arms falling forward in OHSA, no pain. Programming: add thoracic extension mobility, wall slides, face pulls; regress overhead press to landmine press until ROM improves; avoid heavy behind-neck pressing.

  • When to Refer
  • Pain during screen (not just stiffness)
  • Numbness/tingling
  • Recent trauma swelling
  • Suspected stress fracture
  • Exam Traps

Trap: Diagnosing "rotator cuff tear" from OHSA—screen only suggests mobility/stability trends.

Trap: Stretching without subsequent activation—temporary ROM gains fade without motor control work.

Trap: Ignoring foot pronation in squat assessment—check arch collapse.

Posture and Daily Habits

Desk sedentarism reinforces upper crossed patterns. Counsel micro-breaks , ergonomic monitor height, and pulling volume to balance pressing in programs.

Movement screens embody ISSA's train movements, not muscles philosophy while personalizing correctives. Master observation language for scenario questions.
