—To assess
the oral system of parkinsonian patients treated with
chronic stimulation of the bilateral
subthalamic nucleus (STN) to evaluate precisely the effectiveness of
this procedure on the articulatory organs.
<italic>METHODS</italic>
—Load sensitive
cantilevers were used to sample ramp and hold force contractions
generated by the upper lip, lower lip, and tongue. The subject was
given the instruction to produce forces as rapidly and as accurately as
possible in response to the target signal (ranging from 0.25 to 2 N),
which appeared on a screen. Maximal force of each effector organ was
also measured. Fourteen healthy control subjects and 10 patients
participated in this study. After an overnight fast the patients were
evaluated in the morning under two conditions: during bilateral
stimulation and 1 hour after stopping STN stimulation.
<italic>RESULTS</italic>
—During STN
stimulation, dynamic and static control of the articulatory organs were
improved: the maximal strength of the articulatory organs, their
accuracy to reach the target, and the precision of the hold phase
increased. In addition, the reaction time and the rise time of the ramp
phase decreased. Patients' speech as assessed by the item 18 of the
unified Parkinson's disease rating scale (UPDRS) was greatly improved
by electrical stimulation of the STN
<italic>CONCLUSIONS</italic>
—Improvement
of oral control of the stimulated patients suggests that STN
stimulation modulates neuronal structures involved in speech. However,
more patients have to be evaluated for a fuller understanding of the
effect of this surgical procedure on speech.
