Articulatory dysfunction in multiple sclerosis: An electropalatographic study

2007-08-14T00:00:00Z

Dysfunction of the articulatory subsystem (i.c.. the lips, tongue, and jaw) has bccn identified as a major contributor to the reduction in speech intelligibility experienced by a high proportion of people with multiple sclerosis (MS). In particular. consonant imprecision has been reported to be the articulatory deficit that contributes most to variations in overall intelligibility of MS speakers. Electropalatography(EPG) IS an instrurncntal technique that visually documents the location and timing of tongue-topalatc contacts during speech. Although such a technique would be valuablc in objectively assessing the articulatory disturbances exhibited by individuals with dysarthria ia motor speech disorder) associated with MS, to-date no such study ha< been reported. The aim of the present study was to use EPG to assess tongue-to-palate contact patterns and articulatory timing in patients with dysarthria associated with MS. A dysarthric participant with a diagnosis of definite MS was fitted with an acrylic EPG palate (Reading EPG.?) and asked to read aloud a list of single syllable words which contained lingual consonants in the word-initial position and in consonant clusters. Each mord was repeated five times. The EPG palate was specifically moulded to tit the participant's hard palate and contained 62 electrodes that detected the tongue contacts. A non-neurologically impaired participant matched for age and sex servcd as a control. The results of the study revealed that the tongue-to-palate contacts produced by the participant with MS varied from those produced by the control in a number of ways in regard to spatial configurations and timing characteristics exhibited. The rcsults arc discussed in relation to the neuropathophysiological effects of MS on speech production. The potcntial use of EPG in programs for treating speech disorders associated with MS will be highlightcd.

Articulatory function following traumatic brain injury in childhood: A perceptual and instrumental analysis

Cahill, LM og Murdoch, BE og Theodoros, DG — 2007-08-15T00:00:00Z

Primary objective: To investigate the articulatory function of a group of children with traumatic brain injury (TBI), using both perceptual and instrumental techniques. Research design: The performance of 24 children with TBI was assessed on a battery of perceptual (Frenchay Dysarthria Assessment, Assessment of Intelligibility of Dysarthric Speech and speech sample analysis) and instrumental ( lip and tongue pressure transduction systems) assessments and compared with that of 24 non-neurologically impaired children matched for age and sex. Main outcomes: Perceptual assessment identified consonant and vowel imprecision, increased length of phonemes and overall reduction in speech intelligibility, while instrumental assessment revealed significant impairment in lip and tongue function in the TBI group, with rate and pressure in repetitive lip and tongue tasks particularly impaired. Significant negative correlations were identified between the degree of deviance of perceptual articulatory features and decreased function on many non-speech measures of lip function, as well as maximum tongue pressure and fine force tongue control at 20% of maximum tongue pressure. Additionally, sub-clinical articulatory deficits were identified in the children with TBI who were non-dysarthric. Conclusion: The results of the instrumental assessment of lip and tongue function support the finding of substantial articulatory dysfunction in this group of children following TBI. Hence, remediation of articulatory function should be a therapeutic priority in these children.

Articulatory function in hypokinetic dysarthria: An electropalatographic examination of two cases

2007-08-15T00:00:00Z

The present study employed electropalatography (EPG) and a nonspeech measure of lingual function to examine, in detail, the articulatory production deficits of two individuals with Parkinson disease (PD) and hypokinetic dysarthria. Participants read 10 repetitions of CV words contained within the carrier phrase I saw a _ today while wearing an EPG artificial palate. Target consonants included the alveolar stop /t/, lateral approximant /l/, and the alveolar fricative /s/ in the /a/ vowel environment. The results of the two participants were compared to an age-matched control group. Examination of the perceptual features of articulatory production, lingual strength, fine force control and endurance, tongue-palate contact patterns, and segment durations were conducted. Results of the study revealed quite different articulatory deficits in the two participants. Specifically, the articulation of Participant One (P1) was characterized by a fast rate of speech, undershooting of articulatory targets, and reduced duration of consonant closures. In contrast, Participant Two (P2) demonstrated tongue-palate contact patterns indicative of impaired lingual control in the presence of both normal and increased articulatory segment durations. Potential reasons for the differing articulatory deficits were hypothesized. The current study demonstrated that assessment with EPG identified potential causes of consonant imprecision in two individuals with hypokinetic dysarthria. Directions for speech pathology intervention, salient from the results of the study, were also noted.

Articulatory imprecision in dysarthria following childhood cerebellar tumor: A perceptual and acoustic investigation of three male participants

2007-08-15T00:00:00Z

Articulatory imprecision has been documented as a key perceptual feature of the dysarthria associated with childhood cerebellar tumor (CCT). As yet the underlying acoustic and physiological characteristics of motor speech production that contribute to this perceptual feature have not been identified. The aim of the current study was to describe perceptual and acoustic characteristics of consonant production in three children with dysarthria associated with CCT The results indicated that in all three cases the timing of articulatory movements during stop consonant production differed from that measured in a control group of same-age peers. The impact of cerebellar lesions in adulthood on articulatory gestures is used as a reference for discussing the findings of the current study with similarities evident. Also discussed are future research directions for examining the underlying acoustic or physiological basis for articulatory imprecision in children with dysarthria associated with CCT.

Articulatory kinematics in the dysarthria associated with Friedreich's Ataxia

2011-10-09T00:04:23Z

Electromagnetic articulography (EMA) was used to investigate the tongue kinematics in the dysarthria associated with Friedreich's ataxia (FRDA). The subject group consisted of four individuals diagnosed with FRDA. Five nonneurologically impaired individuals, matched for age and gender, served as controls. Each participant was assessed using the AG-200 EMA system during six repetitions of the tongue tip sentence Tess told Dan to stay fit and the tongue back sentence Karl got a croaking frog. Results revealed reduced speed measures (i.e., maximum acceleration / deceleration / velocity), greater movement durations and increased articulatory distances for the approach phases of consonant productions. The approach phase, involving movement up to the palate, was more affected than the release phase. It is suggested that deviant lingual kinematics could be the outcome of disturbances to cerebellar function, or possibly in combination with disturbances to upper motor neuron systems.

Asperger syndrome and/or high functioning autism: Clinical application of findings from research into language and communication skills.

2008-03-11T00:00:00Z

Background: Historically the terms Asperger syndrome (AS) and high functioning autism (HFA) have been used synonymously. The inclusion of AS as categorically distinct from Autistic Disorder in DSM-IV, however, constituted a break from the historical view of AS and HFA being similar presentations. Yet the question of a shared etiology between AS and HFA has defined a number of differing theoretical approaches to examining the language and communication abilities associated with the disorders. Debate regarding the external validation of AS from HFA has been the focus of research for more than a decade. Within the same time frame, and separate from the validation debate, a small number of studies have examined a range of language and communication skills associated with participant groups composed of individuals with autism with normal intelligence, AS, and/or HFA. In response to the validation debate, an alternative conceptualization, that of AS and HFA being presentations on a spectrum of autistic disorders, has been proposed. Aims: This review seeks to establish whether recent research findings have had a positive contribution to the clinical understanding of language and communication difficulties associated with AS and HFA. Conclusions: An evaluation of the literature suggests that the ongoing validation debate has had limited research and clinical value. Furthermore, the review findings suggest that conclusions from combined AS/HFA studies have limited clinical application due to the heterogeneity of the AS/HFA presentation. The results of the current review suggest that the conceptualization of AS and HFA as presentations on a spectrum of autistic disorders may have more useful application, both in research and clinical practice.

Assembly and insertion of a self-fitting hearing aid: design of effective instruction materials

2013-02-06T12:28:06Z

A self-fitting hearing aid has been proposed as a viable option to meet the need for rehabilitation in areas where audiology services are unreliable. A successful outcome with a self-fitting hearing aid pivots in part on the clarity of the instructions accompanying the device. The aims of this article are (a) to review the literature to determine features that should be incorporated into written health-care materials and factors to consider in the design process when developing written instructions for a target audience of older adults and (b) to apply this information to the development of a set of written instructions as the first step in self-fitting of a hearing aid, assembling four parts and inserting the aid into the ear. The method involved a literature review of published peer reviewed research. The literature revealed four steps in the development of written health-care materials: planning, design, assessment of suitability, and pilot testing. Best practice design principles for each step were applied in the development of instructions for how to assemble and insert a hearing aid. Separate booklets were developed for the left and right aids and the content of each consisted of simple line drawings accompanied by captions. The reading level was Grade 3.5 equivalent and the Flesch Reading Ease Score was 91.1 indicating that the materials were “very easy” to read. It is essential to follow best practice design principles when developing written health-care materials to motivate the reader, maximize comprehension, and increase the likelihood of successful application of the content.

Assessing childrens competence in computer interactions: Preliminary reliability and validity of the test of mouse proficiency

Lane, A og Ziviani, J — 2007-08-14T19:27:56Z

The Test of Mouse Proficiency (TOMP) was developed to assist occupational therapists and education professionals assess computer mouse competency skills in children from preschool to upper primary (elementary) school age. The preliminary reliability and validity of TOMP are reported in this paper. Methods used to examine the internal consistency, test-retest reliability, and criterion- and construct-related validity of the test are elaborated. In the continuing process of test refinement, these preliminary studies support to varying degrees the reliability and validity of TOMP. Recommendations for further validation of the assessment are discussed along with indications for potential clinical application.

Assessing children's speech intelligibility and oral structures, and functions via an internet-based telehealth system

2012-11-30T18:58:04Z

We examined the validity and reliability of an Internet-based telehealth system for screening speech intelligibility and oro-motor structure, and function in children with speech disorders. Twenty children aged 4-9 years were assessed by a clinician in the conventional, face-to-face (FTF) manner; simultaneously, they were assessed by a second clinician via the videoconferencing system using a 128-kbit/s Internet connection. Speech intelligibility in conversation was rated and an informal assessment of oro-motor structure and function was conducted. There was a high level of agreement between the online and FTF speech intelligibility ratings, with 70% exact agreement and 100% close agreement (within ± point on a 5-point scale). The weighted kappa statistic revealed very good agreement between raters (kappa = 0.86). Data for online and FTF ratings of oro-motor function revealed overall exact agreement of 73%, close agreement of 96%, moderate or good strength of agreement for six variables (kappa = 0.48–0.74), and poor to fair agreement for six variables (kappa = 0.12–0.36). Intra- and inter-rater reliability measures (ICCs) were similar between the online and FTF assessments. Low levels of agreement for some oro-motor variables highlighted the subjectivity of this assessment. However, the overall results support the validity and reliability of Internet-based screening of speech intelligibility and oro-motor function in children with speech disorders.

Assessing dysphagia via telerehabilitation: patient perceptions and satisfaction

2012-09-26T10:50:24Z

To gain insight into factors which may infl uence future acceptance of dysphagia management via telerehabilitation, patients’ perceptions were examined before and after a telerehabilitation assessment session. Forty adult patients with dysphagia(M = 66 years, SD = 16.25) completed pre- and post-session questionnaires which consisted of 14 matched questions worded to suit pre- and post-conditions. Questions explored comfort with the use of telerehabilitation, satisfaction with audio and video quality, benefi ts of telerehabilitation assessments and patients’ preferred assessment modality. Questions were rated on a 5-point scale (1 = strongly disagree, 3 = unsure, 5 = strongly agree). Patients’ comfort with assessment via telerehabilitation was high in over 80% of the group both pre- and post-assessment. Pre-assessment, patients were unsure what to expect with the auditory and visual aspects of the videoconference, however there were signifi cant positive changes reported post-experience. In relation to perceived benefits of telerehabilitation services in general, most patients believed in the value of telerehabilitation and post-assessment this increased to 90 – 100% agreement. Although 92% felt they would be comfortable receiving services via telerehabilitation, 45% of patients indicated ultimate preference for a traditional faceto-face assessment. The data highlight that patients are interested in and willing to receive services via telerehabilitation; however, any concerns should be addressed pre-assessment.

Assessment and management of dysphagia following pharyngolaryngectomy with free jejunal interposition: A series of eight case studies

Ward, EC og Frisby, J og O'Connor, D — 2007-08-14T00:00:00Z

The physiological and structural deficits contributing to swallowing complications in the pharyngolaryngectomy patient population are not homogeneous. Consequently, a team approach, involving medical investigations as well as clinical and radiological assessments of swallowing, is necessary to facilitate diagnosis of the underlying impairment and assist the medical/surgical and speech pathology team members in the process of individualizing the management plan for each patient. In the present study, the clinical assessment and management of eight pharyngolaryngectomy patients who presented with a decline in swallowing function unrelated to immediate postsurgical effects or direct effects of radiotherapy are reported. Clinical and radiological investigations revealed a heterogeneous group of factors contributing to their swallowing impairments and disability levels, including difficulty with graft and anastomotic patency and graft motility, impaired lingual coordination, increased bolus transit time, nasal and oral regurgitation, patient distress, and recurrence. Variation between the cases supported the need for differential intervention and management plans for all eight patients. Ratings of perceived swallowing disability, handicap, and well-being/distress levels at initial assessment and again six months following dysphagia intervention revealed a pattern of reduced levels of impairment, functional disability, and overall patient distress levels following informed intervention. The present case study data highlights the key role thorough clinical and radiological investigations play in the process of diagnosing the factors contributing to dysphagia and guiding the management of the resultant swallowing disability in the pharyngolaryngectomy population.
