Treatment Sequences

Treatment programs of four improving ataxic dysarthric speakers are reviewed. Treatment sequences were based on two overall measures of speech performance—intelligibility and prosody. Increases in intelligibility were initially achieved by control of speaking rate. A hierarchy of rate control strategies, ranging from a rigid imposition of rate through rhythmic cueing to self-monitored rate control is discussed. As speakers improved their monitoring skills, a compromise was made between intelligibility and rate. Normal prosodic patterns were not achieved by the ataxic speakers due to difficulty in precisely coordinating the subtle fundamental frequency, loudness and timing adjustments needed to signal stress. Three of the four subjects were taught to use only durational adjustments to signal stress. In this way, they were able to achieve stress on targeted words consistently and minimize bizarreness which resulted from sweeping changes in fundamental frequency and bursts of loudness. The need for further clinically oriented research is discussed.

Stress Patterns

Cineradiographic and spectrographs analyses were performed to study the speech production of a subject who presented the classical neurologic signs of cerebellar lesion and who had speech characteristics like those that have been reported for ataxic dysarthria. These analyses were conducted with special attention to the deviant perceptual dimensions that have been described for ataxic speech. Examination of the cineradiographic and spectrographic records revealed conspicuous abnormalities in speaking rate, stress patterns, articulatory placements for both vowels and consonants, velocities of articulator movements, and fundamental frequency contours. In general, our physiological and acoustic observations of ataxic dysarthria were compatible wth existing perceptual descriptions of this condition. The data for the subject are discussed in the light of current hypotheses concerning cerebellar participation in the regulation of skilled movement. Particular suggestions are made concerning the nature of the neuromuscular abnormalities that may underlie the aberrant motorics of ataxic dysarthria.

Normal Speaking

An intensive study of a normal-speaking subject, proficient in the use of buccal speech, was conducted. With respect to voice fundamental frequency variability, phonation time, and speaking rate his buccal speech characteristics compared favorably with those reported for excellent esophageal speakers. However, the reduced intelligibility of his buccal speech on rhyme-test words, the high average fundamental frequency of his buccal voice, and his conspicuous buccal gestures during speech represent distinct vocal liabilities.

Ataxic Dysarthria

Purpose Following recent attempts to quantify articulatory impairment in speech, the present study evaluates the usefulness of a novel measure of motor stability to characterize dysarthria. Method The study included 8 speakers with ataxic dysarthria (AD), 16 speakers with hypokinetic dysarthria (HD) as a result of Parkinson's disease, and 24 unimpaired control participants. Each participant performed a series of sentence repetitions under habitual, fast, and slow speaking rate conditions. An algorithm to measure utterance-to-utterance spectro-temporal variation (UUV; Cummins, 2009) was used. Speech rate and intelligibility were also measured. Results UUV scores were significantly correlated with perceptually based intelligibility scores. There were significant differences in UUV between control speakers and the AD but not the HD groups, presumably because of differences in intelligibility in the samples used and not because of differences in pathology. Habitual speaking rate did not correlate with UUV scores. All speaker groups had greater UUV levels in the slow conditions compared with habitual and fast speaking rates. Conclusions UUV results were consistent with those of other variability indices and thus appear to capture motor control issues in a similar way. The results suggest that the UUV could be developed into an easy-to-use clinical tool that could function as a valid and reliable assessment and outcome measure.

A prospective 1-year observational survey was designed to assess the management and control of atrial fibrillation (AF) in eight countries within the Asia-Pacific region. Patients ( N = 2,604) with recently diagnosed AF or a history of AF ≤1 year were included. Clinicians chose the treatment strategy (rhythm or rate control) according to their standard practice and medical discretion. The primary endpoint was therapeutic success. At baseline, rhythm- and rate-control strategies were applied to 35.7% and 64.3% of patients, respectively. At 12 months, therapeutic success was 43.2% overall. Being assigned to rhythm-control strategy at baseline was associated with a higher therapeutic success (46.5% vs 41.4%; P = 0.0214) and a lower incidence of clinical outcomes (10.4% vs 17.1% P < 0.0001). Patients assigned to rate-control strategies at baseline had higher cardiovascular morbidities (history of heart failure or valvular heart disease). Cardiovascular outcomes may be less dependent on the choice of treatment strategy than cardiovascular comorbidities.
