| dc.description.abstract | Objective: Fasciculations are occasionally observed in root lesions, but their site of origin is uncertain. Methods: We studied the origin of fasciculations (FPs) in consecutive patients with mild chronic L5 root lesions, excluding peripheral nerve lesion. We used a novel technique of double-EMG needle recording, in which each needle was placed in the territory of separate motor units. With this technique the observation of synchronous FPs implies an origin proximal to distal axonal branching. Results: FPs were found in 13% of 84 consecutive patients with mild chronic L5 root lesions. In 25% they were synchronous in different motor units. Conclusions: We suggest that in mild L5 root lesions most FPs have an origin at distal branches but some FPs originate proximally (25%), possibly at the site of nerve compression. Significance: The proximal site of compression and more distal sites may both initiate fasciculation potentials in proximal root lesions. | pt_PT |
