Post-Stroke Shoulder Pain and Early Mobilization
A 68-year-old right-handed retired machinist had a left middle cerebral artery infarct 11 days ago. He has dense right hemiparesis (Medical Research Council grade 1/5 in the shoulder, 2/5 in the elbow), right hemianopia, and moderate expressive aphasia. He is medically stable: blood pressure 138/84, heart rate 78, oxygen saturation 96% on room air, no fever. His wife reports he cries out when the nursing staff move his right arm during bed changes and points to the top of the shoulder. On examination he has pain at end range of passive shoulder flexion (about 70 degrees) and abduction (about 60 degrees), with no redness, swelling, or warmth. Passive range into external rotation is limited to 20 degrees with a firm end feel. A referral note states 'begin intensive upper limb rehabilitation immediately.' He is able to sit on the edge of the bed with one-person assistance for 5 minutes and cannot stand without maximal help. The ward physiotherapist has 30 minutes per day with him and a shared gym slot. The family asks why he is not yet walking and wants 'the arm worked hard so it does not freeze.'
1. Interpret the shoulder findings. What is the most likely explanation for the pain and restricted external rotation, and how should this change the plan for the upper limb?
Read the worked answer
The findings point to a painful hemiplegic shoulder with a soft-tissue restriction rather than a single benign cause. The key discriminators:
- Firm end feel into external rotation at 20 degrees suggests capsular or rotator cuff soft-tissue restriction, not spasticity alone. Spasticity typically gives a velocity-dependent catch, not a hard capsular stop at a fixed angle.
- Pain at end-range flexion and abduction with no heat, redness, or swelling makes infection or acute fracture unlikely, but does not exclude a low-grade cuff problem or adhesive capsulitis developing in an immobile joint.
- Absence of warmth/erythema lowers the priority of cellulitis or septic arthritis, but a low-grade temperature should still be checked; if fever or systemic signs appear, escalate.
This is not an indication for 'intensive' end-range stretching. The immediate priorities are pain control, protection of the shoulder in a supported position (lap tray or arm trough, not a sling that pulls the humerus into adduction and internal rotation), and gentle pain-free range within the available arc. Aggressive end-range work in a painful, restricted shoulder risks increasing pain and reducing participation. The plan should be: analgesia review with the medical team, positioning education for nursing, gentle active-assisted range to the point of first pain (not through it), and scapular and trunk control work that does not provoke the shoulder. Document baseline range and pain score (for example a 0-10 numeric rating) so change can be tracked. Reassess in 48-72 hours; if external rotation remains under 20 degrees with a firm end feel and pain persists, discuss with the medical team for imaging or corticosteroid injection consideration, and continue protected mobilization meanwhile.
2. The referral asks for 'intensive upper limb rehabilitation immediately.' How do you reconcile this with the patient's current status, and what does the evidence and your clinical judgement support in the first two weeks?
Read the worked answer
'Intensive' is a prescription, not a mandate to override safety. The reconciliation is to define intensity in terms of repetitions and meaningful task practice within a safe envelope, not end-range stretching or forced movement.
What the evidence supports early after stroke:
- High-repetition, task-specific practice is associated with better upper limb outcomes, but the dose must be tolerated. With grade 1-2/5 shoulder and elbow strength, meaningful active task practice is limited; much of the early work is preparatory (trunk control, scapular setting, supported reach) and should be graded.
- Very early and intensive mobilization protocols have been studied mainly for gait and general mobility, and some trials raised safety concerns about very early high-dose mobilization. The same caution applies to forcing a painful shoulder.
- Constraint-induced movement therapy is not appropriate now: the arm has too little active movement, and the patient has hemianopia and aphasia that affect safety and communication.
A defensible plan for the next two weeks: daily 30-minute sessions combining (1) supported, pain-free active-assisted range and scapular control; (2) trunk and sitting balance to enable reach; (3) simple functional tasks (touching a target, sliding objects on a table) with the affected arm where possible; (4) positioning and handling education for nursing and family. Coordinate with the speech-language therapist for aphasia-friendly instructions and with occupational therapy for ADL retraining. Set a review point: if pain is controlled and range improves, progress dose; if pain worsens, step back and reassess. Document the rationale for not following the 'intensive' instruction literally, so the team understands the decision is clinical, not neglect.
3. The family wants to know why he is not walking and asks you to 'work the arm hard so it does not freeze.' How do you respond, and what does this reveal about your professional obligations?
Read the worked answer
Respond with honesty, plain language, and a concrete plan. A workable structure:
- Acknowledge the concern - the fear of a frozen, useless arm and the wish to see walking are reasonable.
- Explain the current barrier - he cannot yet stand safely without maximal help; walking practice requires trunk control and safe standing, which are being built now. Forcing standing before he is safe risks falls, and the ward has one physiotherapist for 30 minutes daily.
- Explain the arm - the shoulder is painful and stiff at the moment. Working it 'hard' through pain can make it worse. The plan is to keep it moving gently, protect it in good positions, and build control before adding load.
- Give a timeline and a role for the family - for example, positioning the arm on a pillow or lap tray, encouraging him to use the affected hand in simple daily tasks, and reporting pain changes.
Professional obligations this engages:
- Informed consent and shared decision-making: the family is asking for a treatment; you must explain benefits and risks, not simply refuse.
- Duty of care and non-maleficence: following an unsafe instruction to satisfy a family request would breach this.
- Honesty about resources: the 30-minute daily allocation is a real constraint; saying so is appropriate, and escalating for more therapy time through the team is a legitimate advocacy step.
- Documentation: record the discussion, the family's concerns, and the agreed plan.
- Scope and referral: if the family remains distressed or the pain is not controlled, involve the medical team and, where available, a psychologist or social worker.
