6.4 Movement Screens, Interpretation, and Referral
Key Takeaways
- Screen the patterns you intend to train: bend-and-lift observation, a single-leg or hurdle-style step, a shoulder push and pull, thoracic rotation, and static and dynamic balance.
- A screen finding is a control observation that routes into program design — a regression, a corrective priority, or a different exercise — not a diagnosis of a structure.
- Knee valgus during a squat is a control finding until a clinician says otherwise, and it usually shouts during movement even when standing posture looked acceptable.
- Pain, radiating or neurological symptoms, or an unexplained loss of function during any screen stops the screen and triggers a referral to an appropriate allied health professional.
- Interpretation is what makes Task 3 useful to Domain II: each screen result should change a specific exercise, range, or phase decision in the written program.
6.4 Movement Screens, Interpretation, and Referral
Quick Answer: Domain I Task 3 Skill 4 selects movement and balance screens that load the five patterns just enough to expose control: squat, single-leg or hurdle step, push and pull, thoracic rotation, and static/dynamic balance. Skill 5 is interpreting those screens so program design changes. You do not diagnose pathology — pain, radiating symptoms, or an unexplained loss of function makes it a referral.
Static views told you what the client looks like standing still, and the mobility battery told you what range exists. Screens ask the only question that matters for program design: does that range survive when the client actually moves? Each screen below maps to one of the five foundational patterns from 6.2, so a finding here routes straight into a Functional or Movement phase decision.
Movement and Balance Screens Used in ACE-Style Practice
Skill 4 is assessing movement and balance. ACE’s own teaching and the IFT Movement phase organize this around the five patterns. Commercial batteries such as a trademarked hurdle-and-squat system can look similar. Do not call any trademarked screen “the ACE test.” ACE does not require you to buy a branded kit or to assign a 0–3 proprietary score. You do need to watch the patterns with a consistent setup and write down what you saw.
Use a clear view (front and side), shoes off if safe, and a depth or height the client can attempt without pain. Demonstrate once. Cue the task (“sit to the box and stand”), not a paragraph of anatomy. Watch two or three reps, not twenty. Fatigue turns a screen into a conditioning set.
Bend-and-lift / squat observation
Client stands with feet about hip- to shoulder-width, sits back and down toward a box or to a comfortable depth, then stands. You are watching a bend-and-lift pattern, not grading a powerlifting squat.
Look for: heels staying down; knees tracking roughly over the mid-foot rather than diving into valgus; a torso that hinges at the hips without the lumbar spine suddenly flexing or cranking into more lordosis; relatively even weight left to right; a breath that does not become a held Valsalva panic. Common regressions if it fails: sit-to-stand to a higher box, heel-elevated squat to temporarily borrow missing dorsiflexion, or a supported squat to a TRX or doorframe so the hips can learn the path.
Single-leg or hurdle-style step
Client stands tall and either holds a single-leg stance or steps over a low line / mini-hurdle and back. The point is stance-leg control, not a track hurdle.
Look for: level pelvis (no contralateral hip drop), knee that does not dump inward, trunk that does not crash sideways, foot that does not spin or collapse, and the ability to stop without a hop. A client who runs three days a week can still fail this. That finding keeps them in Functional / Movement work for single-leg patterns even if their cardio sits in Fitness.
Shoulder push and pull
Push: a slow wall, incline, or floor push-up. Watch scapulae (winging, hiking), lumbar sag or pike, head drop, and whether the elbows share the work. Pull: a standing cable or band row, or an inverted row if the client has the strength. Watch for a shrug, a lumbar yank, a chin poke, and one-sided yanking.
If the floor push-up collapses, you have not learned that the pecs are weak. You have learned that this closed-chain push is too hard to display a clean pattern. Raise the hands. If the row is a jump, lighten the band and ask for a two-second hold at the ribs.
Thoracic rotation
Seated with a tall spine, or half-kneeling to lock the pelvis, the client rotates as if looking over a shoulder or opens the top arm in an open-book. Compare sides. Lumbar twisting, breath-holding, and a huge side-to-side gap are the findings. This screen explains ugly chops, ugly golf-adjacent goals, and some shoulder-push faults that were never about the shoulder.
Balance, static and dynamic
Static: bipedal stance with eyes open, then a narrow stance, then single-leg, then — only if safe — eyes closed. Dynamic: a slow step-down from a low box, a reach, or a short tandem walk. Stop if the client is a fall risk you have not spotted and referred. Older adults, prenatal clients, and anyone with neuropathy need a closer spot and a simpler task. Balance is a stability screen, not a circus act for social media.
| Screen | What “good enough to load later” looks like | Typical first regression |
|---|---|---|
| Bend-and-lift | Heels down, lumbar curve roughly unchanged, knees track, even left-right | Higher sit-to-stand; support the hands |
| Single-leg / hurdle-style | Pelvis level, no valgus, quiet trunk | Assist the hand; shorten the step; shorter hold |
| Push | Scapulae glide, ribs down, no lumbar sag | Wall or incline push-up |
| Pull | Scapula sets, no shrug or lumbar yank | Lighter band; chest-supported row |
| Thoracic rotation | Motion from the thorax, lumbar quiet, sides similar | Open-book on the floor; smaller range |
| Balance | Controlled stillness or a controlled step | Wider base; support; eyes open only |
Interpreting Screens for Program Design
Skill 5 is the point of the hour. A screen that does not change the next session was a show.
Map findings to IFT muscular phases. Ugly static posture plus a collapsing bird-dog plus a sagging push-up = Functional work: core, scapular, foot, and hip-stability drills, mobility for the stiff neighbors, and no hurry to load the five patterns. Clean static posture but a valgus squat and a hip-drop step-up = Movement work: pattern regressions, then pattern practice in all three planes, still mostly body weight or light load. Clean patterns with a performance goal = you may enter Load/Speed on those patterns, not on the ones that still leak.
Choose mobility or stability, not both at random. Limited ankle dorsiflexion plus heels rising = mobility (and then immediately a squat variation that uses the new range). Quiet glute medius plus a hip drop = stability and a shorter single-leg task. A stiff thorax plus lumbar extension on the press = thoracic extension mobility and anti-extension core stability. Stretching an already wandering lumbar spine because “the back feels tight” is a classic miss; tightness can be a stability complaint.
Regress before you correct with load. The corrective implication inside Task 3 is program design, not a rehabilitation protocol. Raise the box. Shorten the lever. Slow the tempo. Change the chain (a supported squat instead of a free squat). Keep the client successful. A regression that the client owns beats a “corrective circuit” they hate and skip.
Do not diagnose pathology. “You have kyphosis from a weak mid-trap” is already too medical if you say it as a diagnosis. “I see a rounded upper-back starting position, and your overhead press turns into a backbend. We will work thoracic extension and a wall press before we go heavy overhead” is Task 3 done correctly. You do not name disc herniations, labral tears, scoliosis grades, or “upper-crossed disease.”
Worked example — valgus squat, no pain: Priya’s intake is a desk job and weekend hikes. Static sagittal view shows a mild anterior pelvic tilt. The squat shows both knees diving in at the bottom; single-leg stance on the right shows a hip drop at second three. No pain, no numbness. Interpretation: frontal-plane control is the limiter, likely a mix of hip-abductor stability and a pronating foot, with desk-related hip position in the background. Program: sit-to-stand to a higher box with a light band above the knees if that cue improves tracking; side-lying or standing hip-abduction that does not roll the pelvis; short-foot or single-leg stance holds; hiking stays, but loaded walking lunges wait. You did not tell her she has a “bad ACL waiting to happen.” You told her what you will train.
Worked example — daily activity explains the hinge: Marcus is a mechanic. Static view shows a flattened lumbar curve and a forward head. His bend-and-lift immediately becomes lumbar flexion at mid-thigh, which is how he spends paid hours. Interpretation: the occupational pattern is grooved; hip-hinge skill and thoracic extension are the project. You do not shame the job. You teach a hip hinge to a higher target, build a dead-bug that keeps the ribs down, and ask how to set the shop bench so not every bolt is a lumbar flex. The screen changed the program and a work conversation.
When a Screen Becomes a Referral
Screens stay inside scope until they do not. Stop the assessment and refer — or activate the emergency action plan — when you see:
- Pain that is sharp, worsening, or not clearly just “hard work.” A screen should not be performed into pain “to see if it loosens up.”
- Neurologic signs: numbness, tingling, burning, radiating pain into a limb, unexplained weakness, foot drop, or a sudden change in bowel or bladder function (the last is emergency-level, not a next-week physical-therapy suggestion).
- Dizziness, fainting, chest pressure, unusual dyspnea, or poor perfusion during a simple stance or squat — those are Chapter 3 red flags, not movement puzzles.
- A new, unexplained deformity, swelling, or inability to bear weight.
- A client who cannot complete a basic screen because of post-operative restrictions you have not seen in writing, or a clinician’s note that forbids the pattern.
Document what you saw in the client’s words and in your observation, what you did not do (no loaded squat, no “let’s push through”), and whom you referred to (physician, physical therapist, emergency services). Offer to collaborate after the clinician sets boundaries. Virtual screens follow the same stop rules. A frozen video feed during a single-leg stance is a reason to stop, not a reason to guess that the hip drop “was probably fine.”
Movement screens make you a better programmer. They do not make you a diagnostic clinician. That line is the difference between Task 3 and a scope-of-practice item from Domain IV.
During a single-leg stance screen the client reports sharp radiating pain and tingling into the foot. What is the correct action?
A pain-free squat screen shows both knees collapsing inward at the bottom. How should the trainer use that result?
A cleared client completes a pain-free hurdle-style single-leg step, but the pelvis drops on the stance side and the trunk leans by the third repetition. What is the most appropriate use of that screen result?
