Abstract
We studied the discharge pattern of motor units (MUs) from the first dorsal interosseous muscle during slight stationary isometric contraction. In six controls, seven patients with parkinsonism, and five patients with choreic disorders, we analyzed 78 MUs. About one-half of the MUs in both patient groups fired irregularly as shown by interval histograms, joint interval histograms, and corresponding statistical calculations. Cross-correlation techniques revealed a characteristic type of MU synchronization in parkinsonism. Analysis of the MU discharge pattern can be useful in clinical assessment of these disorders.This publication has 7 references indexed in Scilit:
