TL;DR: The articulatory function of the labial musculature has been investigated electromyographically before and after treatment with l-dopa in patients with Parkinsonism who had dysarthria, and normalization of the EMG articulatory pattern was paralleled by an improvement of the Dysarthria.
Abstract: The articulatory function of the labial musculature has been investigated electromyographically before and after treatment with l-dopa in patients with Parkinsonism who had dysarthria. Before medication the EMG traces generally showed a constant, abnormally increased, tonic activity, together with disturbed reciprocal innervation, which impaired the articulatory activity. After medication the tonic hyperactivity was reduced and the reciprocal innervation re-established. This normalization of the EMG articulatory pattern was paralleled by an improvement of the dysarthria.

TL;DR: The term itself is difficult of definition, but it is generally thought to imply a delay in initiation of movement combined with slowness and restriction in amplitude of movements once initiated.
Abstract: IMPAIRMENT of speech, leading sometimes to unintelligibility, was recognized by Parkinson1 to be part of the disease which now bears his name. Reduced voice volume, dysarthria and prosodic monotony are common manifestations of Parkinsonism2 and are generally attributed to hypokinesis, a cardinal feature of the disease, the physiological basis of which is ill understood. The term itself is difficult of definition, but it is generally thought to imply a delay in initiation of movement combined with slowness and restriction in amplitude of movements once initiated.
