PD Check-In: The development and trial of a supported self-management program for people with Parkinson's disease following intensive speech intervention.

BACKGROUND: Debilitating speech and communication changes in Parkinson's disease (PD) lead to diminished quality of life for people with PD and their communication partners. Maintenance of the long-term effects of treatment such as LSVT LOUD® remains equivocal. Development of supported long-term maintenance programs is warranted. AIMS: This article describes the development and preliminary outcome data for PD Check-In, a supported self-management intervention for the maintenance of speech and social communication for people with PD following LSVT LOUD. METHODS & PROCEDURES: A narrative literature review of the principles of self-management and social cognitive theory of self-regulation was conducted to develop the core elements of PD Check-In. PD Check-In was conducted in person by a speech and language therapist (SLT) for three participants at 6 and 12 weeks, and at 6, 12 and 24 months following LSVT LOUD. Outcome measures included vocal intensity (SPL) during monologue and the dysarthria impact profile (DIP). PD Check-In utilized semi-structured discussion to develop, evaluate, and support the self-efficacy and skill of the person with PD in maintaining speech and social communication. OUTCOMES & RESULTS: Six conceptual elements of PD Check-In were identified in the development phase: partnerships, self-reflection, maintenance issues, revision, goal-setting and maintenance strategies. Preliminary intervention data revealed monologue vocal intensity at 24 months post-LSVT LOUD was maintained above pre-treatment level, but below levels achieved post-treatment. The psychosocial impact of speech changes from pre-LSVT LOUD to 24 months post-treatment as measured by the DIP was variable. Qualitative statements reflected participant experiences underlying the clinical data. CONCLUSIONS & IMPLICATIONS: The theoretical and practical underpinnings of PD Check-In were defined. The impact of PD Check-In on three persons with PD was variable but positive. Further evaluation of the model is warranted. WHAT THIS PAPER ADDS: What is already known on the subject LSVT LOUD provides efficacious treatment for the speech disorder associated with PD. Long-term maintenance of speech post-treatment varies following self-managed and group therapy interventions. People with PD have an unmet expectation of long-term maintenance of speech and improved quality of life following intensive treatment. What this paper adds to existing knowledge This study describes the development of a novel clinic-based approach to long-term maintenance of speech in PD based on the principles of self-management and self-efficacy. It provides preliminary data to demonstrate the method and its effects on three participants with varying speech difficulty, self-management skill development and psychosocial impact. What are the potential or actual clinical implications of this work? The positive impact of PD Check-In on the maintenance of monologue vocal intensity above baseline 24 months post-intensive treatment was independent of the variable impact on the quality of life of the participants. Further exploration of PD Check-In is warranted to determine the efficacy of this approach.

Lee Silverman Voice Treatment for dysarthria in patients with Parkinson's disease: a systematic review and meta-analysis.

Approximately 89% of patients with Parkinson's disease (PD) suffer from dysarthria. Lee Silverman Voice Treatment (LSVT), a behavioral therapy, aims to improve speech and voice functions. The objective was to assess the effectiveness of LSVT compared with other/no speech interventions for dysarthria in patients with PD. Electronic databases, including PubMed, Embase and the Cochrane Library, were searched. The publication date of all included studies was before 6 March 2020. Only randomized controlled trials (RCTs) that evaluated the LSVT intervention compared with other/no speech intervention were considered. The data obtained from the included studies were described and the mean differences were calculated. Eight RCTs were included in this meta-analysis comparing LSVT with other/no speech interventions. In the comparison of LSVT versus no intervention, vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage', monologue and describing a picture increased by 8.87, 4.34, 3.25 and 3.31 dB, respectively, after 1 month of therapy. Compared with the respiratory therapy group, the LSVT group also showed significant improvement in vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage' and monologue immediately after treatment (13.39, 6.66 and 3.19 dB). Positive improvement still existed after 24 months. There was no difference in the therapeutic effect between face-to-face and online LSVT. The effectiveness of LSVT for dysarthria in patients with PD was verified in these trials. However, future RCTs with sufficient participants are essential to evaluate the effectiveness of LSVT for dysarthria.

Acoustic changes in the speech of children with cerebral palsy following an intensive program of dysarthria therapy.

BACKGROUND: The speech intelligibility of children with dysarthria and cerebral palsy has been observed to increase following therapy focusing on respiration and phonation. AIMS: To determine if speech intelligibility change following intervention is associated with change in acoustic measures of voice. METHODS & PROCEDURES: We recorded 16 young people with cerebral palsy and dysarthria (nine girls; mean age 14 years, SD = 2; nine spastic type, two dyskinetic, four mixed; one Worster-Drought) producing speech in two conditions (single words, connected speech) twice before and twice after therapy focusing on respiration, phonation and rate. In both single-word and connected speech we measured vocal intensity (root mean square-RMS), period-to-period variability (Shimmer APQ, Jitter RAP and PPQ) and harmonics-to-noise ratio (HNR). In connected speech we also measured mean fundamental frequency, utterance duration in seconds and speech and articulation rate (syllables/s with and without pauses respectively). All acoustic measures were made using Praat. Intelligibility was calculated in previous research. OUTCOMES & RESULTS: In single words statistically significant but very small reductions were observed in period-to-period variability following therapy: Shimmer APQ -0.15 (95% CI = -0.21 to -0.09); Jitter RAP -0.08 (95% CI = -0.14 to -0.01); Jitter PPQ -0.08 (95% CI = -0.15 to -0.01). No changes in period-to-period perturbation across phrases in connected speech were detected. However, changes in connected speech were observed in phrase length, rate and intensity. Following therapy, mean utterance duration increased by 1.11 s (95% CI = 0.37-1.86) when measured with pauses and by 1.13 s (95% CI = 0.40-1.85) when measured without pauses. Articulation rate increased by 0.07 syllables/s (95% CI = 0.02-0.13); speech rate increased by 0.06 syllables/s (95% CI = < 0.01-0.12); and intensity increased by 0.03 Pascals (95% CI = 0.02-0.04). There was a gradual reduction in mean fundamental frequency across all time points (-11.85 Hz, 95% CI = -19.84 to -3.86). Only increases in the intensity of single words (0.37 Pascals, 95% CI = 0.10-0.65) and reductions in fundamental frequency (-0.11 Hz, 95% CI = -0.21 to -0.02) in connected speech were associated with gains in intelligibility. CONCLUSIONS & IMPLICATIONS: Mean reductions in impairment in vocal function following therapy observed were small and most are unlikely to be clinically significant. Changes in vocal control did not explain improved intelligibility.

Prosodic Improvement in Persons with Parkinson Disease Receiving SPEAK OUT!® Voice Therapy.

BACKGROUND/AIMS: Hypokinetic dysarthria in Parkinson disease (PD) hinders the ability to verbally communicate and interferes with activities of daily living. SPEAK OUT!® is a therapy program designed to improve functional communicative ability. In contrast to the Lee Silverman Voice Treatment program, SPEAK OUT!® promotes speaking with intent to effect loud speech. This study evaluated the efficacy of SPEAK OUT!® in persons with idiopathic PD in 3 domains: self-reported voice handicap, clinical ratings of dysarthria and prosody, and acoustic analysis of prosody. PARTICIPANTS AND METHODS: Pre-/post-therapy data included PD participants' scores on the Voice Handicap Index (VHI) and the Voice-Related Quality of Life (V-RQOL) questionnaire, audio recordings, perceptual evaluation scores, and demographic data, such as age, sex, handedness, diagnosis, and onset of PD. RESULTS: Participants achieved a statistically and clinically significant improvement in speech intensity, pitch range, normalized pairwise variability index for pitch, sustained vowel duration, reading intelligibility, and vocal quality after SPEAK OUT!® training, consistent with both of the self-report voice scores, i.e., the VHI and the V-RQOL, and with the perceptual speech evaluation scores. Longer PD duration was associated with lowered efficacy. CONCLUSIONS: SPEAK OUT!® is effective and should be administered as early as possible after disease onset.

Effects of SPEAK OUT! & LOUD Crowd on Functional Speech Measures in Parkinson's Disease.

PURPOSE: This study investigated the effects of the SPEAK OUT! & LOUD Crowd therapy program on speaking rate, percent pause time, intelligibility, naturalness, and communicative participation in individuals with Parkinson's disease (PD). METHOD: Six adults with PD completed 12 individual SPEAK OUT! sessions across four consecutive weeks followed by group-based LOUD Crowd sessions for five consecutive weeks. Most therapy sessions were conducted via telehealth, with two participants completing the SPEAK OUT! portion in person. Speech samples were recorded at six time points: three baseline time points prior to SPEAK OUT!, two post-SPEAK OUT! time points, and one post-LOUD Crowd time point. Acoustic measures of speaking rate and percent pause time and listener ratings of speech intelligibility and naturalness were obtained for each time point. Participant self-ratings of communicative participation were also collected at pre- and posttreatment time points. RESULTS: Results showed significant improvement in communicative participation scores at a group level following completion of the SPEAK OUT! & LOUD Crowd treatment program. Two participants showed a significant decrease in speaking rate and increase in percent pause time following treatment. Changes in intelligibility and naturalness were not statistically significant. CONCLUSIONS: These findings provide preliminary support for the effectiveness of the SPEAK OUT! & LOUD Crowd treatment program in improving communicative participation for people with mild-to-moderate hypokinetic dysarthria secondary to PD. This study is also the first to demonstrate positive effects of this treatment program for people receiving the therapy via telehealth.

Changes in voice quality after speech-language therapy intervention in older children with cerebral palsy.

OBJECTIVE: We examined whether perceived voice quality is altered in a group of children with cerebral palsy (CP) following an intervention focusing on respiration and phonation, and whether possible improvements might be associated with increased intelligibility levels. METHODS: Sixteen individuals with CP and dysarthria (9 girls, mean age 14 years, SD = 2; 9 with spastic type CP, 2 dyskinetic, 4 mixed, 1 Worster-Drought syndrome) completed intelligibility assessments on separate days twice before intervention, at termination of treatment and at 6-week follow-up using 50 words from the Children's Speech Intelligibility Measure lists, and describing cartoon strips. Experienced speech-language pathologists rated voice quality employing GRBAS scales. RESULTS: There was no clear evidence that change in voice quality pre-post intervention was large compared with change in the pre-intervention or post-intervention periods. Asthenia demonstrated largest improvement (effect size of 0.4). Intelligibility correlated weakly with Grade, Breathiness and Asthenia, but not with Roughness or Strain. A deterioration of 1 unit on the Grade and Asthenia scales was associated with an approximately 11% decrease in intelligibility. CONCLUSION: Perceived changes in voice quality were small compared to changes in intelligibility. Further investigations must examine other variables potentially associated with intelligibility gain to better understand the links between the respiratory-phonatory intervention and improved intelligibility.

Lateral cerebellothalamic tract activation underlies DBS therapy for Essential Tremor.

BACKGROUND: While deep brain stimulation (DBS) therapy can be effective at suppressing tremor in individuals with medication-refractory Essential Tremor, patient outcome variability remains a significant challenge across centers. Proximity of active electrodes to the cerebellothalamic tract (CTT) is likely important in suppressing tremor, but how tremor control and side effects relate to targeting parcellations within the CTT and other pathways in and around the ventral intermediate (VIM) nucleus of thalamus remain unclear. METHODS: Using ultra-high field (7T) MRI, we developed high-dimensional, subject-specific pathway activation models for 23 directional DBS leads. Modeled pathway activations were compared with post-hoc analysis of clinician-optimized DBS settings, paresthesia thresholds, and dysarthria thresholds. Mixed-effect models were utilized to determine how the six parcellated regions of the CTT and how six other pathways in and around the VIM contributed to tremor suppression and induction of side effects. RESULTS: The lateral portion of the CTT had the highest activation at clinical settings (p < 0.05) and a significant effect on tremor suppression (p < 0.001). Activation of the medial lemniscus and posterior-medial CTT was significantly associated with severity of paresthesias (p < 0.001). Activation of the anterior-medial CTT had a significant association with dysarthria (p < 0.05). CONCLUSIONS: This study provides a detailed understanding of the fiber pathways responsible for therapy and side effects of DBS for Essential Tremor, and suggests a model-based programming approach will enable more selective activation of lateral fibers within the CTT.

Intensive voice treatment (the Lee Silverman Voice Treatment [LSVT®LOUD]) for individuals with Wilson's disease and adult cerebral palsy: two case reports.

Objective: In this case report, we aimed to examine the effects of an intensive voice treatment (the Lee Silverman Voice Treatment [LSVT®LOUD]) for Wilson's disease (WD), and adult cerebral palsy (CP), and dysarthria.Method: The participants received LSVT®LOUD four times a week for 4 weeks. Acoustic, perceptual (GRBAS) analyses were performed and data from the Voice Handicap Index (VHI) were obtained before and after treatment.Results: Besides the Harmonics-to Noise Ratio (HNR) value (dB) of the participant with WD, for both participants' fundamental frequencies (Hz), jitter (%), and shimmer (%) values showed significant differences (p < .05) after therapy. Both participants showed significant improvements (p < .05) in the duration (s) and the sound pressure level (dB, SPL) of sustained vowel phonation (/a/), in SPL (dB) of pitch range (high and low /a/) and reading and conversation (p < .01). There was a positive improvement in the high-frequency values (Hz) of both participants but not in the low-frequency values (Hz) in the participant with WD. Perceptual analysis with GRBAS judgements of sustained vowel (/a/) and paragraph reading of two participants also showed improvement. After therapy, perceived loudness of the participants' voice increased.Conclusions: The findings provide some preliminary observations that the individuals with WD and the adult individuals with CP can respond positively to intensive speech treatment such as LSVT®LOUD. Further studies are needed to investigate speech treatments specific to WD and adult CP.

The effect of smooth speech on the speech production of an individual with ataxic dysarthria.

PURPOSE: To examine the effects of an intensive Smooth Speech therapy technique on the speech production of an individual with ataxic dysarthria and on the individual's level of functioning on the domains of the International Classification of Functioning, Disability and Health (ICF). METHOD: This study utilized a single-subject experimental design. One individual with ataxic dysarthria took part in an intensive Smooth Speech therapy programme. Measurements of the participant's speech and level of functioning on the domains of the ICF were made before therapy, after 1 week of intensive therapy, after 7 weeks of follow-up therapy and 4 weeks after completion of therapy. RESULTS: No significant change in speech intelligibility was evident following Smooth Speech therapy. However, significant improvements in the participant's ability to achieve improved speech naturalness through enhanced control of prosodic elements and more comprehensible speech were evident. The participant also demonstrated an improved level of functioning on selected domains of the ICF. CONCLUSIONS: The results of this study indicate that elements of Smooth Speech Therapy may prove effective in the treatment of ataxic dysarthria, particularly in the treatment of prosodic defects.

Diagnosis and treatment of bulbar symptoms in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is the most common neurodegenerative disease of the motor system. Bulbar symptoms such as dysphagia and dysarthria are frequent features of ALS and can result in reductions in life expectancy and quality of life. These dysfunctions are assessed by clinical examination and by use of instrumented methods such as fiberendoscopic evaluation of swallowing and videofluoroscopy. Laryngospasm, another well-known complication of ALS, commonly comes to light during intubation and extubation procedures in patients undergoing surgery. Laryngeal and pharyngeal complications are treated by use of an array of measures, including body positioning, compensatory techniques, voice and breathing exercises, communication devices, dietary modifications, various safety strategies, and neuropsychological assistance. Meticulous monitoring of clinical symptoms and close cooperation within a multidisciplinary team (physicians, speech and language therapists, occupational therapists, dietitians, caregivers, the patients and their relatives) are vital.

[Effects of tongue acupuncture combined with rehabilitation training group of dysarthria on speech function in post-stroke dysarthria patients].

OBJECTIVE: To observe the effects of tongue and nape acupuncture combined with rehabilitation training group of dysarthria on speech function in post-stroke dysarthria patients, and to explore the treatment of dysarthria. METHODS: Eighty patients with dysarthria were randomly divided into an observation group (40 cases) and a control group (40 cases). The patients in the two groups were treated with conventional treatment. The patients in the control group were treated with the acupuncture combined with rehabilitation training group of dysarthria; the patients in the observation group were treated with the control group treatment and tongue acupuncture, once a day, 6 days per week for 2 weeks. The patients were evaluated with general dysarthria scale and dysarthria checklist of Chinese Rehabilitation Study Center before and after 2-week treatment. RESULTS: After treatment, the total score and each item score of general dysarthria scale were reduced (all P<0.05); all the score in the observation group was lower than those in the control group (all P<0.05), except the score of jaw which had no significant difference between the two groups. After treatment, the dysarthria checklist of Chinese Rehabilitation Study Center in the observation group was superior to that in the control group (P<0.05). The total effective rate was 85.0% (34/40) in the observation group, which was higher than 67.5% (27/40) in the control group (P<0.05). CONCLUSION: Tongue acupuncture, nape acupuncture and rehabilitation training group of dysarthria could effectively improve the speech function of post-stroke dysarthria patients.

The role of music therapy in an interdisciplinary approach to address functional communication in complex neuro-communication disorders: a case report.

PURPOSE: This paper presents a case report of collaborative work between speech and language therapy (SLT) and music therapy (MT) in the case of an individual presenting with complex communication difficulties and lability caused by pseudo-Parkinsonian vascular disease. DESIGN: MT intervention was used to investigate whether participation could be enabled in a client presenting with complex problems as well as facilitate change in communication parameters which remained unresponsive to conventional SLT intervention. A single case design measured communication and well-being parameters using pre-, during and post-intervention measures. In addition, analysis of the client's musical responses was undertaken to examine changes in vocal functioning which are involved in communication. RESULTS: Analysis of the client's performance during MT intervention revealed improvements in prosody and phonation, with positive reports of participation, reduced incidence of lability and improvements in measures of well-being. CONCLUSIONS: The results indicate the value of such collaborative working in addition to making recommendations for the modification of existing treatment protocols. The findings highlight that fatigue is a major consideration when working with people with severe and complex clinical presentations.

Palliative care in amyotrophic lateral sclerosis.

The poor prognosis of amyotrophic lateral sclerosis (ALS) makes palliative care a challenge for the neurologist. Most disabilities associated with progressive disease can be ameliorated by symptomatic treatment. Prognosis and treatment options should be openly discussed with the patient and his/her relatives. Nutritional deficiency due to pronounced dysphagia can be efficiently relieved by a percutaneous enterogastrostomy. Respiratory insufficiency can be treated by non-invasive ventilation at home, provided the familial environment is supportive. Adequate assistance and palliative treatment in the terminal phase is of paramount importance.

[Speech therapy of dysarthria in Parkinson's disease]. / La rééducation orthophonique de la dysarthrie dans la maladie de Parkinson.

The treatment of speech impairment, a factor of loneliness, speech therapy to treat dysarthria in Parkinson's disease is a fundamental aspect of patient management. The impact of medicinal treatment of dysarthria is controversial and surgery appears to worsen the problem. Various speech therapy approaches are relaxation, postural rehabilitation, respiration, phonation, articulation and prosodic re-education. AN INTERESTING METHOD: This overview underlines the fundamental principles of speech therapy in Parkinson's disease and compares the main methods and their results. We particularly insist on the Lee Silverman Voice Treatment (LSVT), phonation re-education method that has been widely developed in the United-States. Our aim is to provide better knowledge on this re-education method in France.

Use of the extended therapy outcome measure for children with dysarthria.

Increasing demand on healthcare resources has led to a greater emphasis on the examination of the impact of service delivery on outcomes. Clinical assessments frequently do not cover all aspects of change associated with interventions for those with complex conditions. This paper reviews the need for more comprehensive outcome measurement suitable for clinical practice and benchmarking. It describes an extension of the Therapy Outcome Measure for specific use in reflecting the impact of the broad range of interventions commonly required when managing children with dysarthria. Three case histories are used to illustrate the approach, and data from four speech-language pathology services are used to illustrate the value of benchmarking.

Individual and environmental contributions to treatment outcomes following a neuroplasticity-principled speech treatment (LSVT LOUD) in children with dysarthria secondary to cerebral palsy: a case study review.

This study describes the use of a neuroplasticity-principled speech treatment approach (LSVT(®)LOUD) with children who have dysarthria secondary to cerebral palsy. To date, the authors have treated 25 children with mild-to-severe dysarthria, a continuum of gross and fine motor functions, and variable cognitive abilities. From this data set, two case studies are presented that represent as weak or strong responders to LSVT LOUD. These case studies demonstrate how individual and environmental features may impact immediate and lasting responses to treatment. Principles that drive activity-dependent neuroplasticity are embedded in LSVT LOUD and may contribute to positive therapeutic and acoustic outcomes. However, examination of the response patterns indicated that intensity (within and across treatment sessions) is necessary but not sufficient for change. Weak responders may require a longer treatment phase, better timing (e.g., developmentally, socially), and a more prominent desire to communicate successfully during daily activities. Strong responders appear to benefit from the intensity and saliency of treatment as well as from intrinsic and extrinsic rewards for using the trained skills for everyday communication. Finally, possibilities are presented for technological solutions designed to promote accessibility to the intensive task repetition and maintenance required to drive lasting changes.

Dysarthria in stroke: a narrative review of its description and the outcome of intervention.

Dysarthria is a frequent and persisting sequel to stroke and arises from varied lesion locations. Although the presence of dysarthria is well documented, for stroke there are scant data on presentation and intervention outcome. A literature search was undertaken to evaluate (a) the features of dysarthria in adult stroke populations relative to the conventional Mayo system for classification, which was developed from diverse pathological groups, and (b) the current status of evidence for the effectiveness of intervention in dysarthria caused by stroke. A narrative review of results is presented. The limited data available indicate that, regardless of stroke location, imprecise articulation and slow speaking rate are consistent features, and voice disturbances, especially harshness, and reduced prosodic variation are also common. Dysarthria is more prevalent in left than in right hemisphere lesions. There is a need for comprehensive, thorough analysis of dysarthria features, involving larger populations, with stroke and other variables controlled and with appropriate age-referenced control data. There is low level evidence for benefits arising from intervention in stroke-related dysarthria. Because studies involve few participants, without external control, and sometimes include stroke with other aetiologies, their results lack the required weight for confident evidence-based practice.

Changes to articulation following LSVT(R) and traditional dysarthria therapy in non-progressive dysarthria.

The present study aimed to evaluate the effects of the Lee Silverman Voice Treatment (LSVT(R)) on acoustic and perceptual measures of articulation in non-progressive dysarthria in comparison to traditional dysarthria therapy. The study involved 26 individuals with non-progressive dysarthria who were randomly allocated to receive either LSVT(R) or traditional dysarthria therapy (TRAD), both of which were administered for 16 hourly sessions over 4 weeks. Participants' speech samples were collected over a total of six testing sessions during three assessment phases: (1) prior to treatment, (2) immediately post-treatment, and (3) 6 months post-treatment (FU). Speech samples were analysed perceptually to determine articulatory precision and intelligibility as well as acoustically using vowel space (and vowel formant measures) and first moment differences. Results revealed short and long-term significant increases in vowel space area following LSVT(R). Significantly increased intelligibility was also found at FU in the LSVT(R) group. No significant differences between groups for any variables were found. The study reveals that LSVT(R) may be a suitable treatment option for improving vowel articulation and subsequent intelligibility in some individuals with non-progressive dysarthria.
