Biomechanical Parameters of Voice in Parkinson's Disease Patients.

INTRODUCTION: Previous research on voice in Parkinson's disease (PD) has consistently demonstrated alterations in acoustic parameters, including fundamental frequency (F0), maximum phonation time, Shimmer, and Jitter. However, investigations into acoustic parameter alterations in individuals with PD are limited. METHODS: We conducted an experimental study involving 20 PD patients (six women and fourteen men). Subjective measures of voice (VHI-30 scale and GRBAS) and objective measures using the OnlineLAB App tool for analyzing biomechanical correlates of voice were recorded. The app analyzed a total of 22 biomechanical parameters of voice. RESULTS: The results of subjective measures were consistent with findings from previous studies. However, the results of objective measures did not align with studies that employed acoustic measures. CONCLUSIONS: The biomechanical analysis revealed alterations in various parameters according to gender. These findings open up a new avenue of research in voice analysis for patients with PD, whether through acoustic or biomechanical analysis, aiming to determine whether the observed changes in these patients' voices are attributable to age or disease progression. This line of investigation will help elucidate the relative contribution of these factors to vocal alterations in PD patients and provide a more comprehensive understanding of the underlying mechanisms.

Voice Sequelae Following Recovery From COVID-19.

INTRODUCTION: Covid-19 is an infectious disease with a different symptomatic implication depending on each person. There are sequelae in the nervous, cardiovascular, and/or digestive system that involve the approach and multidisciplinary work of different health professionals where the speech therapist is included. In this way, we can speak of a direct relationship between speech therapy and Covid-19; especially in those patients with serious sequelae such as the inability to eat and/or speak and the loss of voice. The damage caused to the laryngeal mucosa triggers the loss of some of the qualities of the voice, limiting oral communication. That is why we can find dysphonias caused by a great weakness, by a continuous overexertion or because of a paralysis of the vocal cords. OBJECTIVES/HYPOTHESIS: The objective of this study was to identify the patterns of behavior in the biomechanical correlates of people who passed Covid-19 symptomatically with sequelae in voice. METHODS: An experimental study with a total of 21 participants (11 women and 10 men) with sequelae in voice post Covid-19 is presented. Voice samples were collected and biomechanical correlates were analyzed through the Voice Clinical Systems program. RESULTS AND CONCLUSIONS: The results show different altered biomechanical patterns between men and women that correlate with other infectious diseases.

Análisis de los patrones acústicos e intervención logopédica mediante la técnica Lax Vox en la distrofia muscular oculofaríngea. Descripción de un caso / Analysis of acoustic patterns and logopedic intervention using Lax Vox technique in oculopharyngeal dystrophy. Description of a case

INTRODUCCIÓN Y OBJETIVO: La distrofia muscular oculofaríngea es una enfermedad genética que afecta a los músculos proximales de las extremidades, ptosis de los párpados y disfagia orofaríngea. En consecuencia, el perfil clínico de estos pacientes podría estar acompañado de disfonía, disartria y pérdida de peso. Las alteraciones de la voz, la articulación y la deglución caracterizan el perfil de la disartrofonía. Se presenta un caso clínico de una paciente con distrofia muscular oculofaríngea que ha sido remitida al servicio de logopedia con el objetivo de rehabilitar su voz. Descripción: La novedad que presenta este caso en la intervención logopédica, es que ha sido rehabilitada mediante técnicas de tracto vocal semiocluído. RESULTADOS: Los resultados obtenidos muestran la efectividad del Lax vox, en la rehabilitación de la paciente. DISCUSIÓN: En la búsqueda bibliográfica hemos encontrado evidencia científica de la efectividad del Lax Vox en pacientes con disfonía, nódulos, pólipos, edemas; pero no hemos encontrado evidencia de la efectividad del Lax Vox en pacientes con distrofia muscular oculofaríngea. CONCLUSIONES: El uso de la técnica Lax vox para la rehabilitación de los pacientes con distrofia muscular óculo-faríngea es beneficiosa

INTRODUCTION AND OBJECTIVE: Oculopharyngeal muscular dystrophy is a genetic disease that affects the proximal muscles of the extremities, ptosis of the eyelids and oropharyngeal dysphagia. Consequently, the clinical profile of these patients could be accompanied by dysphonia, dysarthria and weight loss. The alterations of the voice, the articulation and the swallowing characterize the profile of the disartrofonía. We present a clinical case of a patient with oculo-pharyngeal muscular dystrophy who has been referred to the sevice of speech therapy with the aim of rehabilitating her voice. Description: The novelty that this case presents in the speech therapy intervention is that it has been rehabilitated using semiocluid vocal tract tecniques. RESULTS: The results obtained show the effectiveness of Lax vox in the rehabilitation of the patient. DISCUSSION: In the literature search we have found scientific evidence of the effectiveness of Lax Vox in patients with dysphonia, nodules, polyps, edema; but we have not found evidence of the effectiveness of Lax Vox in patients with oculopharyngeal muscular dystrophy. CONCLUSIONS: With these results, we can conclude that the use of the Lax vox technique for the rehabilitation of patients with oculopharyngeal muscular dystrophy is beneficial
