Objective automatic assessment of rehabilitative speech treatment in Parkinson's disease

Vocal performance degradation is a common symptom for the vast majority of Parkinson's disease (PD) subjects, who typically follow personalized one-to-one periodic rehabilitation meetings with speech experts over a long-term period. Recently, a novel computer program called Lee Silverman voice treatment (LSVT) Companion was developed to allow PD subjects to independently progress through a rehabilitative treatment session. This study is part of the assessment of the LSVT Companion, aiming to investigate the potential of using sustained vowel phonations towards objectively and automatically replicating the speech experts' assessments of PD subjects' voices as “acceptable” (a clinician would allow persisting during in-person rehabilitation treatment) or “unacceptable” (a clinician would not allow persisting during in-person rehabilitation treatment). We characterize each of the 156 sustained vowel /a/ phonations with 309 dysphonia measures, select a parsimonious subset using a robust feature selection algorithm, and automatically distinguish the two cohorts (acceptable versus unacceptable) with about 90% overall accuracy. Moreover, we illustrate the potential of the proposed methodology as a probabilistic decision support tool to speech experts to assess a phonation as “acceptable” or “unacceptable.” We envisage the findings of this study being a first step towards improving the effectiveness of an automated rehabilitative speech assessment tool

Strategies to ensure motor learning during the treatment of vocal problems in neurodegenerative diseases

Los déficits del sistema sensoriomotor tienen un efecto dramático sobre la calidad de vida de las personas con enfermedades neurodegenerativas, especialmente la afectación de los nervios craneales responsables de la deglución, fonoarticulación, expresión facial y voz. Actualmente existe evidencia científica de que al entrenar sistemáticamente los grupos musculares encargados de los movimientos fonorrespiratorios, puede mejorarse o lentificarse el avance de la enfermedad y sus efectos sobre el deterioro sensoriomotor. Sin embargo aún no se ha avanzado lo suficiente en el diseño de estrategias específicas para propiciar la generalización de los resultados terapéuticos, esto es, para favorecer la transferencia de las mejorías desde la clínica a la vida cotidiana del enfermo neurodegenerativo. En este estudio se exponen los principios básicos del aprendizaje motor, sus fases y pautas de administración, centrándose en la aplicación de estos aspectos al tratamiento de personas con problemas de voz de origen neurodegenerativo. En una segunda parte se hace una revisión de la literatura sobre los factores que potencian la efectividad del método LSVT®. Se analiza cómo dicho modelo terapéutico aplica las teorías del aprendizaje motor al tratamiento de los problemas fonatorios de las personas que padecen Parkinson, proporcionando una generalización de las mejorías motoras y una repercusión de dichos beneficios a nivel de la lesión neurológica, la función vocal, la inteligibilidad del habla y la deglución, con resultados terapéuticos que han demostrado mantenerse a corto, medio y largo plazo por encima del nivel previo al tratamiento

LSVT LOUD and LSVT BIG: Behavioral Treatment Programs for Speech and Body Movement in Parkinson Disease

Recent advances in neuroscience have suggested that exercise-based behavioral treatments may improve function and possibly slow progression of motor symptoms in individuals with Parkinson disease (PD). The LSVT (Lee Silverman Voice Treatment) Programs for individuals with PD have been developed and researched over the past 20 years beginning with a focus on the speech motor system (LSVT LOUD) and more recently have been extended to address limb motor systems (LSVT BIG). The unique aspects of the LSVT Programs include the combination of (a) an exclusive target on increasing amplitude (loudness in the speech motor system; bigger movements in the limb motor system), (b) a focus on sensory recalibration to help patients recognize that movements with increased amplitude are within normal limits, even if they feel “too loud” or “too big,” and (c) training self-cueing and attention to action to facilitate long-term maintenance of treatment outcomes. In addition, the intensive mode of delivery is consistent with principles that drive activity-dependent neuroplasticity and motor learning. The purpose of this paper is to provide an integrative discussion of the LSVT Programs including the rationale for their fundamentals, a summary of efficacy data, and a discussion of limitations and future directions for research

Remote Assessment of Parkinson’s Disease Symptom Severity Using the Simulated Cellular Mobile Telephone Network

Telemonitoring of Parkinson’s Disease (PD) has attracted considerable research interest because of its potential to make a lasting, positive impact on the life of patients and their carers. Purpose-built devices have been developed that record various signals which can be associated with average PD symptom severity, as quantified on standard clinical metrics such as the Unified Parkinson’s Disease Rating Scale (UPDRS). Speech signals are particularly promising in this regard, because they can be easily recorded without the use of expensive, dedicated hardware. Previous studies have demonstrated replication of UPDRS to within less than 2 points of a clinical raters’ assessment of symptom severity, using high-quality speech signals collected using dedicated telemonitoring hardware. Here, we investigate the potential of using the standard voice-over-GSM (2G) or UMTS (3G) cellular mobile telephone networks for PD telemonitoring, networks that, together, have greater than 5 billion subscribers worldwide. We test the robustness of this approach using a simulated noisy mobile communication network over which speech signals are transmitted, and approximately 6000 recordings from 42 PD subjects. We show that UPDRS can be estimated to withinless than 3.5 points difference from the clinical raters’ assessment, which is clinically useful given that the inter-rater variability for UPDRS can be as high as 4-5 UPDRS points. This provides compelling evidence that the existing voice telephone network has potential towards facilitating inexpensive, mass-scale PDsymptom telemonitoring applications

Cepstral analysis of hypokinetic and ataxic voices : correlations with perceptual and other acoustic measures

To investigate the validity of cepstral analyses against other conventional acoustic measures of voice quality in determining the perceptual impression in different motor speech disorders—hypokinetic and ataxic dysarthria, and speech tasks—prolonged vowels and connected speech. Prolonged vowel productions and connected speech samples (reading passages and monologues) from 43 participants with Parkinson disease and 10 speakers with ataxia were analyzed perceptually by a trained listener using GRBAS. In addition, acoustic measures of cepstral peak prominence (CPP), smoothed CPP (CPPs), harmonics-to-noise ratio (HNR), shimmer %, shimmer dB, amplitude perturbation quotient (APQ), relative average perturbation (RAP), jitter, and pitch perturbation quotient (PPQ) were performed. Statistical analysis involved correlations between perceptual and acoustic measures, as well as determination of differences across speaker groups and elicitation tasks. CPP and CPPs results showed greater levels of correlation with overall dysphonia, breathiness, and asthenia ratings than the other acoustic measures, except in the case of roughness. Sustained vowel production produced a higher number of significant correlations across all parameters other than connected speech, but task choice did not affect CPP and CPPs results. There were no significant differences in any parameters across the two speaker groups. The results of this study are consistent with the results of other studies investigating the same measures in speakers with nonmotor-related voice pathologies. In addition, there was an indication that they performed better in relation to asthenia, which might be particularly relevant for the current speaker group. The results support the clinical and research use of CPP and CPPs as a quantitative measure of voice quality in populations with motor speech disorder

Oral immunization with pBsVP6-transgenic alfalfa protects mice against rotavirus infection

AbstractA critical factor in edible plant-derived vaccine development is adequate expression of the exogenous antigens in transgenic plants. We synthesized a codon-optimized gene (sVP6) encoding the VP6 protein of human group A rotavirus and inserted it into the alfalfa genome using agrobacterium-mediated transformation. As much as 0.28% of the total soluble protein of the pBsVP6-transgenic alfalfa was sVP6. Female BALB/c mice were gavaged weekly with 10 mg of transgenic alfalfa extract containing 24 μg of sVP6 protein and 10 μg of CpG-rich oligodeoxynucleotides as mucosal adjuvant. Immunized mice developed high titers of anti-VP6 serum IgG and mucosal IgA. Offspring of immunized dams developed less severe diarrhea after challenge with simian rotavirus SA-11, indicating that antibodies generated in the dams provided passive heterotypic protection to the pups. These results suggest that oral immunization with pBsVP6-transgenic alfalfa provides a potential means of protecting children and young animals from severe acute rotavirus-induced diarrhea

A Qualitative Exploration of Former College Student-Athletes’ Wellness

College student-athletes (SAs) may experience difficulties while transitioning from college, which could reduce their overall wellness. However, it is essential to understand positive transition experiences and outcomes, as this can guide future research and intervention efforts. The purpose of this study was to explore the factors that led to higher levels of wellness in former SAs. Semi-structured interviews guided by the Indivisible Self Model were completed with former SAs (n = 12). Overall, participants displayed high levels of wellness - most prominently in terms of work and exercise. Many SAs perceived their current wellness was equal, if not better compared to when they were SAs. These results illustrate examples of successful transitions of former SAs, which can guide future research and interventions

Factors associated with reporting of sexual assault among college and non-college women

Purpose The purpose of this paper is to examine factors impacting college and non-college women reporting sexual assault to police. The goal is to increase knowledge regarding differences in the rates of reporting and reasons for reporting across these two groups. Design/methodology/approach Participants were drawn from a national telephone survey of US women and a sample of US college women. Bivariate and multivariate analyses were conducted to determine factors influencing the reporting of sexual assault to police. Findings Non-college women were more likely than college women to report to police. Women who perceived their victimization as rape were much more likely to report to the police and women who had contact with a helping agency were also much more likely to report their assault. Contacting a helping agency is more relevant to non-college women’s reporting to police, while considering the assault a rape is more important for college women. Practical implications The results suggest that significant work is needed to encourage women in college to view sexual assaults as worthy of reporting. Boosting victim awareness and access to services is paramount. Providing education and empowerment to student victims to inform their perceptions about the definition of rape is vital, as women perceiving sexual assault as rape are more likely to report the incident. Originality/value The research significantly adds to the literature indicating differences in rates of reporting and the factors that impact reporting uniquely for college vs non-college women
