Summary
Shoulder pain is common after stroke, affecting 23% by six months. Severe motor deficits and diabetes increase risk, while institutional care may reduce it.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Epidemiology
Background:
- Shoulder pain is a frequent complication following stroke.
- Understanding its incidence and predictors is crucial for patient management.
Purpose of the Study:
- To quantify the occurrence of shoulder pain post-stroke.
- To identify risk factors predicting shoulder pain development after stroke.
Main Methods:
- Population-based case-cohort study (Auckland Stroke Study).
- Inclusion of all stroke cases over a 12-month period.
- Assessment of self-reported shoulder pain at 1 week, 1 month, and 6 months post-stroke.
Main Results:
- Shoulder pain incidence increased from 17% at 1 week to 23% at 6 months post-stroke.
- Positive associations found between shoulder pain and motor deficit severity and side.
- Significant risk factors for shoulder pain at 6 months included severe upper limb motor deficit (OR 4.94) and diabetes (OR 1.57).
Conclusions:
- Shoulder pain is a prevalent issue after stroke, particularly in individuals with severe sensorimotor deficits and diabetes.
- Patients living at home appear to have a higher risk compared to those in institutional care.
- Targeted management strategies may potentially decrease the incidence of post-stroke shoulder pain.
