Orthopedic Screening (ROM & ROM with Overpressure)
Rapid triage of musculoskeletal pain using a three-step sequence: Active ROM → Passive ROM with Overpressure → Resisted Isometrics.
Goal: Differentiate contractile (muscle–tendon) from inert (capsule, ligament, cartilage, bursa) sources and spot capsular patterns.
Bedside Algorithm
- Active ROM (AROM): Patient moves through full planes. Note range, pain arc, and quality.
- Passive ROM + Overpressure (PROM+OP): Clinician moves the limb to end-range; apply gentle, sustained OP to stress inert tissues.
- Resisted Isometrics: Test mid-range with no joint motion to stress contractile tissue without capsular stretch.
Interpretation Guide
- Pain with AROM only (PROM+OP painless; iso painless) → motor control/load intolerance.
- Pain with PROM+OP (capsular end-feel; AROM limited similarly) → inert structure (capsule/ligament/cartilage/bursa).
- Pain/weakness with isometrics (PROM+OP painless) → contractile lesion (muscle–tendon).
- Pain in all three (esp. at end-range) → severe/irritable; consider joint/bursal inflammation or serious pathology.
Overpressure: firm, controlled end-range load; stop if sharp/replicated red-flag pain.
Region Presets (What to Test)
Shoulder
- AROM: Flex, Abd, ER (at side), IR (hand behind back). Note painful arc (60–120° Abd).
- PROM+OP: Same planes; end-feel/capsular stretch. Capsular pattern: ER > Abd > IR limitation.
- Isometrics: Flex, Abd, ER, IR, elbow flex/ext (rule-out referred biceps/triceps).
Contractile pain ↑ with resisted ER/Abd → rotator cuff; PROM+OP pain end-range → capsulitis/bursal irritation.
Elbow
- AROM: Flex/Ext; Pronation/Supination.
- PROM+OP: End-range flex/ext; OP pron/sup with elbow at 90°.
- Isometrics: Wrist ext (lateral tendon), wrist flex (medial tendon), pron/sup.
Pain with resisted wrist ext > PROM → lateral tendon lesion; end-range ext PROM+OP pain → capsule/impingement.
Wrist/Hand
- AROM: Flex/Ext; Rad/Uln dev; thumb motions.
- PROM+OP: End-range all planes; assess capsular end-feel.
- Isometrics: Wrist flex/ext, RD/UD; thumb abd/opp.
PROM+OP pain with firm end-feel → capsular; focal pain with resisted thumb abd → 1st dorsal compartment tendon.
Hip
- AROM: Flex, Ext, Abd/Add, ER/IR (90° flex).
- PROM+OP: End-range in each plane; Capsular pattern: IR > Flex > Abd (often).
- Isometrics: Flex, Ext, Abd/Add, ER/IR.
Pain with OP IR/Flex suggests intra-articular; isolated pain with resisted Abd → gluteal tendon.
Knee
- AROM: Flex/Ext; note locking/catching.
- PROM+OP: End-range flex/ext; tibial IR/ER in 90° flex for joint line pain.
- Isometrics: Quad set, hamstring, ankle PF/DF (regional screening).
PROM+OP joint-line pain with rotation → meniscus; resisted quad pain > PROM → patellar/quad tendon.
Ankle/Foot
- AROM: DF/PF; Inv/Ev; great toe ext.
- PROM+OP: End-range DF/PF; talocrural and subtalar stress.
- Isometrics: DF, PF, Inv, Ev; great toe ext.
Pain with resisted PF (mid-range) → Achilles tendon; PROM+OP Inv/Ev pain → ligament/capsule.
Cervical Spine
- AROM: Flex/Ext; Rot; SB. Note symptom peripheralization.
- PROM+OP: Overpressure in sitting; assess end-feel and symptom response.
- Isometrics: Flex/Ext/Rot/SB at neutral (break tests gentle).
PROM+OP pain/stiffness across multiple planes → capsular; focal pain with resisted rot → muscular.
Lumbar Spine
- AROM: Flex/Ext; SB; Rot; repeated movements for directional preference.
- PROM+OP: OP via overpressure or passive segmental PA’s.
- Isometrics: Trunk flex/ext (submax), hip isometrics for referral screening.
Centralization with repeated ext → discogenic; PROM+OP pain with firm end-feel → facet/capsular.
Documentation Snapshot
| Region | Plane | AROM | PROM + OP | Isometric | Interpretation |
|---|---|---|---|---|---|
| Shoulder | Abduction | Painful arc 60–120° | End-range pain (capsular/bursal) | Resisted Abd painful/weak | Contractile if iso > PROM; inert if PROM+OP end-range > iso |
| Knee | Flexion + Tibial Rot | Catching/locking | Joint-line pain with OP + rot | Isos painless | Suggests meniscal; add special tests as needed |
| Ankle | Plantarflexion | WNL or painful end-range | PROM Inv/Ev painless | Resisted PF painful/weak | Suggests Achilles tendon involvement |
Add capsular pattern notes where applicable; escalate to diagnostic testing if inert pathology suspected or red flags present.
Stop / Refer Immediately if:
- Severe/unremitting night pain, fever, unexplained weight loss.
- Progressive neuro deficit, cauda equina signs, multi-directional trauma pain.
- Fracture suspicion, infection signs, vascular compromise.
