โœฆ Synopsis

We studied 60 motor units from abductor pollicis brevis, first dorsal interosseous, and abductor digiti minimus muscles in 18 patients with upper motor neuron lesions. Both fractional process parameters and serial correlation coefficients were estimated. The results suggest that both serial correlation coefficients and fractional process parameters can be used to objectively document upper motor neuron disorders in stroke patients. However, each of them may be more sensitive to distinct central motor regulatory mechanisms.

Surface electromyographic (EMG) studies have been widely used to record muscle activity during human motor control studies. 2 However, during studies of single motor unit (SMU) discharge patterns in a clinical setting, a needle electrode has been the electrode of choice because of difficulty in isol

We have not found a ''triphasic'' pattern of muscle activation even during very fast movements. The ''triphasic'' pattern was not evident during eccentric movements either (see
