Hypothesis
To prove the possibility of axillary nerve conduction changes following shoulder subluxation due to hemiplegia.
Conclusion
Continuous traction of the axillary nerve may affect its electro-physiological properties, likely due to shoulder subluxation.
Supporting Evidence
- Mean motor nerve conduction latency was significantly longer in the paralyzed shoulder compared to the sound shoulder.
- Mean CMAP amplitude was significantly lower in the paralyzed shoulder compared to the sound shoulder.
- Electro-physiological changes in the axillary nerve may appear during the first six weeks after stroke.
Takeaway
When someone has a stroke and their arm becomes weak, it can hurt the nerves in their shoulder, making it harder for them to move their arm.
Methodology
Forty-four shoulders of twenty-two patients with flaccid hemiplegia were tested for nerve conduction changes.
Limitations
The study was retrospective and only included patients with first-time stroke.
Participant Demographics
22 patients (8 men, 14 women) with a mean age of 72.5 years.
