Sensory axonal dysfunction in cervical radiculopathy Journal …

WebConclusions The present study demonstrated distal nerve axonal hyperpolarisation in patients with cervical radiculopathy. These findings suggest that the hyperpolarised pattern might be due to Na + -K + ATPase overactivation induced by proximal ischaemia, or could reflect the remyelinating process. WebThe NEE remains the most widely accepted method for confirming the presence of a radiculopathy affecting the motor axons 1. Ideally, six muscles including the paraspinals should be screened for both cervical and lumbar radiculopathies as sensitivities of the NEE are relatively poor 12.

WebSensorimotor polyneuropathy is a bodywide (systemic) process that damages nerve cells, nerve fibers (axons), and nerve coverings ( myelin sheath). Damage to the covering of the nerve cell causes nerve signals to slow or stop. Damage to the nerve fiber or entire nerve cell can make the nerve stop working. WebChronic re-innervation is associated with high amplitude, long duration motor unit potentials with a normal number of phases. As a rule of thumb, motor unit potentials are less than 2 mV in amplitude, and have a duration of 10–5 ms with 3–4 phases.

WebMar 19, 2024 · If very tiny in amplitude, these potentials may persist due to incomplete axonal repair and in a chronic lesion do help to confirm a specific nerve root level of pathology.
