The feasibility of assessing speech and non-speech function of the speech apparatus in adults with cerebral palsy.

Abstract: This short note reports on observations concerning the feasibility of a set of speech and non-speech assessment tasks in an investigation of dysarthria in 21 adults (15 males/6 females; median 23 y...

Motor Speech Disorders and Communication Limitations in Progressive Supranuclear Palsy.

Abstract: Purpose This study describes motor speech disorders and associated communication limitations in six variants of progressive supranuclear palsy (PSP). Method The presence, nature, and severity of dysarthria and apraxia of speech (AOS) were documented, along with scores on the Apraxia of Speech Rating Scale-Version 3 (ASRS-3) for 77 (40 male and 37 female) patients with PSP. Clinician-estimated and patient-estimated communication limitations were rated using the Motor Speech Disorders Severity Rating (MSDSR) Scale and the Communicative Effectiveness Survey (CES), respectively. Descriptive statistics were calculated for each of these dependent variables. One-tailed t tests were conducted to test mean differences in ASRS-3 and CES between participants with and without AOS and between participants with and without dysarthria. Spearman rank correlations were calculated between ASRS-3 scores and clinical judgments of AOS and dysarthria severity and between MSDSR and CES ratings. Results Nine participants (12%) had normal speech. Eighty-seven percent exhibited dysarthria; hypokinetic and mixed hypokinetic-spastic dysarthria were observed most frequently. AOS was observed in 19.5% of participants across all variants, but in only 10% exclusive of the PSP speech and language variant. Nearly half presented with AOS in which neither phonetic nor prosodic features clearly predominated. The mean ASRS-3 score for participants with AOS was significantly higher than for those without and correlated strongly with clinician judgment of AOS severity. Mean ASRS-3 was higher for participants with dysarthria than for those without but correlated weakly with dysarthria severity. Mean MSDSR and CES ratings were lower in participants with AOS compared to those without and moderately correlated with each other. Conclusions Motor speech disorders that negatively impact communicative effectiveness are common in PSP and occur in many variants. This is the first description of motor speech disorders across PSP variants, setting the stage for future research characterizing neuroanatomical correlates, progression of motor speech disorders, and benefits of targeted interventions.

Fundamental frequency patterns in cerebral palsied speech

Abstract: Fundamental frequency (F 0 ) contours provide an acoustic measure that correlates closely with speech intonation. Abnormal intonation patterns have been described as a common feature of dysarthric speech of various origins, including cerebral palsy. However, acoustic descriptions of intonation in dysarthria associated with cerebral palsy are difficult to find. Hence a small exploratory investigation was conducted to describe fundamental frequency patterns of read sentences for three speakers with cerebral palsy and compare them with patterns for normal speakers. Results showed that F 0 variation (as measured by normalized range of F 0 ) for two of the cerebral palsied speakers overlapped that for the normal speakers, and was marginally lower for one cerebral palsied speaker. Fundamental frequency contours for the cerebral palsied speakers appeared to have characteristics that generally were different from the patterns for the normal speakers, and also were different from each other.

Occipital neuralgia and twelfth nerve palsy from a chondromyxoid fibroma

Abstract: The purpose of this case report is to record the unusual combination of occipital neuralgia and hypoglossal nerve palsy causing dysarthria, dysphagia, and unilateral weakness of tongue protrusion, with no other neurological findings. The cause was a discrete tumor in the clivus and the right occipital condyle. Following surgical resection of the tumor, dysarthria and dysphagia persisted. These improved with therapy by a speech therapist, but deviation of the tongue persisted on protrusion. No similar case reports were found in the literature. In addition, the tumor was an unusual one, a chondromyxoid fibroma (CMF); these tumors uncommonly involve the skull base.

Differential motor speech outcomes in children treated for mid-line cerebellar tumour.

Abstract: Primary objective: To investigate the nature of the motor speech impairments and dysarthria that can arise subsequent to treatment for childhood mid-line cerebellar tumours (CMCT).Research design: The motor speech ability of six cases of children with CMCT was analysed using perceptual and physiological measures and compared with that of a group of non-neurologically impaired children matched for age and sex.Main outcome and results: Three of the children with CMCT were perceived to exhibit dysarthric speech, while the remaining three were judged to have normal speech. The speech disorder in three of the children with CMCT was marked by deviances in prosody, articulation and phonation. The underlying pathophysiology was linked to cerebellar damage and expressed as difficulty in co-ordinating the motor speech musculature as required for speech production. These deficits were not identified in the three non-dysarthric children with CMCT.Conclusion: Differential motor speech outcomes occur for children treat...
