Abstract

To study the axillary nerve injury after shoulder sublaxtion in patients of stroke.
Methods:
All eligible and consenting patients of stroke (underwent) electrophysiology studies of both axillary nerve. The parameters include measurement of neuropathy motor latancy, CMAP (compound muscle action potential) &SNAP (sensory nerve action potential) and the conduction velocity. This study included 33 patients with cerebrovascular stroke who were refered to the Physical medicine, Rheumatology and Rehabilitation department at Al-Zahraa University hospital between 1^st April and 31^st December 2012. They were 23 males and 10 females, their ages ranged from 27 to 72 years. The paretic limbs of the patients included were classified as case limbs, while the non-paretic limbs were classified as controls. Results: Axillary nerve latency and amplitude were high significant in shoulder subluxation in the hemiparaetic side in comparison with control significant.
Conclusion: There is lower motor neuron axillary nerve in stroke patients, mixed type (demylinated and axonal), the incidence of axillary nerve lesion is mostly with stroke shoulder subluxation .
