TL;DR: Parker et al. as discussed by the authors reviewed descriptions of paroxysmal dysarthria and ataxia in multiple sclerosis (MS), with special attention given to Parker and his 1946 case series.
Abstract: Objective: To review descriptions of paroxysmal dysarthria and ataxia in multiple sclerosis (MS), with special attention given to Parker and his 1946 case series. Methods: Evaluation of original publications describing paroxysmal dysarthria and ataxia, bibliographic information, writings, and unpublished letters from the Mayo Clinic Historical Unit. Results: In 1940, Storring described a patient with MS with paroxysmal symptoms that included dizziness and trouble speaking, but also unilateral extremity weakness. In 1946, Parker published a series of 11 patients with paroxysmal dysarthria and ataxia. Six of these patients had MS, and he recognized this phenomenon as a manifestation of the disease. The term “paroxysmal dysarthria and ataxia” was first used in 1959 by Andermann and colleagues. Since that time, paroxysmal dysarthria and ataxia has become a well-recognized phenomenon in MS. More recent reports have suggested that the responsible lesion is located in the midbrain, near or involving the red nucleus. Conclusions: Parker was the first to accurately describe paroxysmal dysarthria and ataxia in patients with MS.

TL;DR: Optimal speech outcomes were achieved in 44% of patients and correlated with precise stimulation location within and not outside of the VLp, which was greater for patients with dysarthria than those with normal speech.

TL;DR: Results from the current study suggest that when conducting intelligibility research listening conditions should be standardised and that adult listeners of either gender and any age may be used to test intelligibility outcomes providing hearing acuity is taken into consideration.
Abstract: Little is known about the effects of listener characteristics or listening conditions on intelligibility scores. This study compared intelligibility scores of dysarthric speech achieved under a sta...

TL;DR: The Frenchay Dysarthria Assessment proved to be a valid dysarthria measure in Friedreich's ataxia patients and revealed a significant correlation with the Frenchay dysarthri sum score.
Abstract: Dysarthria is an acquired neurogenic sensorimotor speech symptom and an integral part within the clinical spectrum of ataxia syndromes. Ataxia measurements and disability scores generally focus on the assessment of motor functions. Since comprehensive investigations of dysarthria in ataxias are sparse, we assessed dysarthria in ataxia patients using the Frenchay Dysarthria Assessment. The Frenchay Dysarthria Assessment is a ten-item validated test in which eight items focus on the observation of oral structures and speech functions. Fifteen Friedreich's ataxia patients and 15 healthy control individuals were analyzed using clinical and logopedic methodology. All patients underwent neurological assessment applying the Scale for the Assessment and Rating of Ataxia. In Friedreich's ataxia patients, the Frenchay sub-item voice showed to be most affected compared to healthy individuals followed by items such as reflexes, palate, tongue, and intelligibility. Scoring of lips, jaw, and respiration appeared to be mildly affected. Ataxia severity in Friedreich's ataxia patients revealed a significant correlation with the Frenchay dysarthria sum score. The introduction of a binary Adapted Dysarthria Score additionally allowed allocation to distinct dysarthria pattern in ataxias. The Frenchay Dysarthria Assessment proved to be a valid dysarthria measure in Friedreich's ataxia. Its availability in several languages provides a major advantage regarding the applicability in international clinical studies. Shortcomings of the Frenchay test are the multiplicity of items tested and its alphabetic coding. Numerical scoring and condensation of assessments in a modified version may, however, provide an excellent clinical tool for the measurement and scoring of dysarthria in ataxic speech disorders.
