Shoulder Rehabilitation

The VerdictMODERATE CONVICTION

For most shoulder pain, the answer is loaded exercise.

Right now, run the pain rule on whatever shoulder exercise you currently do. During the rep, pain stays at 2/10 or below. The next day, no flare more than 2/10 above your normal. If both are true, you are loading correctly. If either breaks, drop the load by one step before you stop entirely.

Loading beats resting. Most shoulder pain gets better with the right kind of loaded exercise, not with passive rest, ice, or modalities.
Heavy is not the goal. High-load and low-load programs produce similar disability gains in the published RCTs. Modality matters less than progression.
Criteria, not calendar. You move to the next phase when the shoulder earns it: pain rule held, ROM and strength milestones met. Not because two weeks went by.

Imagine a fraying rope that mends itself overnight. Pull on it too softly during the day and it never gets stronger. Pull on it too hard and the fray gets worse before it can repair. The shoulder works the same way. The pain rule (2/10 during, 2/10 next-day flare) is your signal that today's pull was inside the productive band.

Red Flags — Refer Immediately

Stop and refer if any of these appear

Night pain that disturbs sleep and is unresponsive to position change or load reduction
New neurological symptoms — weakness, numbness, paraesthesia in a dermatomal or myotomal pattern
Systemic features — fever, night sweats, unexplained weight loss
Significant trauma with sudden ROM loss or pseudoparalysis (suspect fracture, massive tear, dislocation)
Sudden popping with strength loss and a drop-arm sign (suspect tear)
Suspected referred cardiac or visceral pain — chest, jaw, left-arm radiation, effort-related

Refer to: GP for systemic features and red-flag escalation. Orthopaedic surgeon for suspected significant structural pathology, fracture, or massive RC tear. A&E for new acute neurological compromise, trauma, or suspected cardiac symptoms.

The Takeaway

Run the pain rule on whatever you currently do

Right now, take whatever shoulder exercise you currently do. During the rep, pain stays at 2/10 or below. The next day, no flare more than 2/10 above your normal. If both are true, you are loading correctly. If either breaks, drop the load by one step before you stop entirely.

What Works

Treatment Hierarchy + Exercise Prescription

Progressive loaded shoulder rehabilitation — cinematic anatomy

Tier 1 STRONG

Progressive loaded exercise (cuff + scapular) — phased, criteria-based progression. Pieters 2020 JOSPT umbrella, GRADE-STRONG. 6-12 weeks for clinically meaningful function gain; 12-26 weeks for full progression.
Phase 1 — irritable shoulder / post-op week 0-6: isometric ER 5x30s daily; pendulums 2x30s/direction daily; scapular squeezes 3x10x5s daily; pain-free arc ROM 2x10 daily

Phase 2 — loading window / week 6-12: side-lying ER 1-3 kg 3x12 3x/wk; resisted scaption 3x12 3x/wk; wall slides 3x10; prone Y raises 3x10; banded row 3x12

Phase 3 — heavy progression (cleared): DB ER at 90 abduction 3x8 2-3x/wk; compound row 3x6-8; press progression incline → flat → overhead 3x6-8; pull-up / pulldown 3x6-8; loaded carries 3x30s/side

Phase 4 — sport / occupational: velocity-loaded plyometric, sport-specific kinetic-chain integration; individualised by therapist
Pain-monitored progression rule — ≤2/10 during exercise; ≤2/10 24-h flare. Operational rule across all loaded protocols. Embedded in CPG framing.

Tier 2 MODERATE

Scapular stabilisation focus when scapular kinematics dominate the deficit pattern. Lower trapezius and serratus anterior progression. Park 2011, Heron 2017. 8-12 weeks for kinematic and disability change.
Early controlled loading after standard arthroscopic RC repair, surgeon-led individualisation. Klintberg 2009, Kjær 2018: equivalent or faster early function vs delayed; not associated with excess re-tear at 24 mo.
BFR loading 20-30% 1RM with cuff occlusion as low-load bridge for cuff-irritable phases needing strength stimulus without high external load. Cardiovascular and DVT screening required.

See Tier 3 — Adjuncts and Emerging

Manual therapy as adjunct EMERGING — short-term pain modulation and ROM gain to support loading. Adjunct, not substitute. Aligns with Pieters 2020 framing.

Pain neuroscience education EMERGING — when kinesiophobia or catastrophising are the rate-limiter on load tolerance. Adjunct.

Velocity / plyometric progression EMERGING — Phase 4 only. Cools 2014 continuum framework.

What Doesn't Work

Passive-only management (modalities, ice, NSAIDs, ultrasound as standalone) — underperforms loaded exercise on 6-12 month function outcomes.
Time-based progression instead of criteria-based — advancing on the calendar regardless of pain, ROM, or strength state. Generates flares and plateau.
"No pain, no gain" gym mentality applied to rehab — pain >5/10 during exercise or >2/10 24-h flare is iatrogenic load, not productive load.
Subacromial decompression as first-line for SAPS without trial of loading. Sham-RCTs (FIMPACT 2018/2021, CSAW 2018) show no advantage over sham at 24 mo or 5 y.
Routine early MRI in primary-care SAPS — does not improve outcomes; treatment-response trial of 6-12 weeks is itself the most reliable diagnostic.

Return to Training

Phase exit and return-to-sport criteria

To exit Phase 1 → Phase 2

Pain ≤2/10 with daily activity
Pain-free arc reaches at least 90° elevation
Tolerates resisted isometrics at 50-70% MVIC without flare

To exit Phase 2 → Phase 3

Phase 2 program completed without 24-h flare for 2 consecutive weeks
Active ROM symmetric or near-symmetric with uninvolved side
Resisted strength testing within 80% of uninvolved side

To exit Phase 3 → Phase 4

Strength symmetric ≥90% of uninvolved side on cuff and scapular tests
Full pain-free ROM
No apprehension on functional or sport-specific positions
DASH or QuickDASH at or near baseline expected score

To return to full sport / occupation

Phase 3 milestones held across 2-4 weeks of progressively sport-specific loading
Sport-specific velocity / volume tolerated without 24-h flare
Symptom-free for 2 consecutive weeks under target load

Conviction

MODERATE

A pragmatic multicentre RCT (N≥600, three arms — PHLE vs LLE vs criteria-based individualised loading; 24-month follow-up; primary endpoints DASH AND occupational return AND ultrasound tendon thickness AND long-term recurrence; pre-registered stratification by initial irritability tier and primary deficit pattern) would update this verdict.

What would change the loading-vs-passive claim?

The HIGH-conviction claim that loaded exercise beats passive-only management for RCRSP is anchored on Pieters 2020 GRADE-STRONG and Ribeiro 2020. A well-powered RCT showing passive modality program produces clinically meaningful DASH gains comparable to a loaded program would force a re-grade.

What would change the high-load-equals-low-load claim?

The MODERATE-HIGH equivalence claim rests on Ingwersen RoCTEx 2017. A pragmatic 24-month RCT showing PHLE produces lower long-term recurrence or better occupational sustainability than LLE, even at DASH-equivalent 12-week outcomes, would re-open the absolute-load question.
