The use of a miniature lip transducer system in the assessment of patients with Parkinsons disease
|
|
|
|
Abstract:
Maxium lip function tasks and measures of interlabial pressure during speech were recorded from 26 patients with Parkinson disease (PD), subdivided into two groups of dysarthric and nondysarthric patients, and a group of 16 control subjects. AU participants were assessed using a miniature pressure transduction system previously reported in Thompson, Murdoch, and Stokes (1997). Group comparisons confirmed the presence of reduced performance on maximum effort tasks relating to pressure, and reduced interlabial pressures during speech production in both subject groups compared to the control group. No significant difference between the dysarthric and nondysarthric patients with PD was observed in the group comparisons, and a cluster analysis involving all patients with PD across all lip parameters revealed no consistent pattern of performance that could differentiate the dysarthric from the nondysarthric patients. A high degree of intersubject variability was noted across the whole group. Within each subgroup, no particular relationship was observed between reduced maximum capacity and interlabial pressures during speech. The present findings raise issues concerning preclinical deficits, individual variability within the articulatory subsystems of subjects with PD, and the relationship between maximum force generating capacity data and motor function during speech.
