Delayed Axillary Nerve Motor Conduction Latency and Reduced CMAP Amplitudes in the Paretic Limbs of Patients With a Cerebrovascular Episode

Abstract

Background: To see for Nerve conduction changes in the axillary nerve in the patients of stroke.

Methods: All eligible and consenting patients of stroke underwent electrophysiology studies of both axillary nerves. The parameters which are looked for the measurement of neuropathy are Motor latency, CMAP (Compound muscle action potential), SNAP (sensory nerve action potential) and the conduction velocity.

Results: CMAP amplitudes were significantly lower, and CML was significantly higher among paretic limbs as compared to non-paretic limb, ie the axillary nerve in the paretic limb gets affected in the patients of stroke.

Conclusion: The study is to prove the probability of axillary nerve injury after shoulder subluxation due to stroke and to improve preventive and rehabilitative measures as even in cases of complete recovery, the disability remains.
