Abstract
To investigate, in patients with Parkinson's disease (PD), the coping strategies; the most reported vocal symptoms; and the relation between coping, voice symptoms, and communicative aspects. Seventy-three subjects were included in the sample, 33 of which were participants in the experimental group (EG) with diagnosis of PD and 40 were control subjects, that is, healthy and without vocal complaints. They underwent the following procedures: application of Voice Symptoms Scale (VoiSS), Brazilian Version; Voice Disability Coping Questionnaire (VDCQ), Brazilian Version; and the questionnaire Living with Dysarthria (LwD). The EG presented deviations in all protocols: VDCQ, with the most frequently coping strategy being "self-control," VoiSS, with "Impairment" as the most prevalent domain, and LwD, presenting changes in all sections. Vocal signs and symptoms and communicative aspects were shown to have a regular correlation with coping. The correlation between vocal symptoms and communicative aspects was as follows: the greater the impairment in communication, the greater the VoiSS emotional scores and the more they complaint of voice-related signs and symptoms. Patients with PD use all kinds of coping strategies, but prefer using self-control. They present several vocal signs and symptoms, and "Impairment" was the most prevalent domain. There are difficulties in all aspects of communication. The higher the occurrence of vocal signs and symptoms, the more the patient reports the difficulties of living with dysarthria, particularly when deviations affect the emotional domain.
Highlights
Parkinson’s disease (PD) is a disorder that causes problems widely described in bodily engines such as bradykinesia, rigidity and resting tremor, and affects various subsystems involved in the speech process, by hypokinetic dysarthria[1,2]
Treatment of speech and voice disorders in people with PD has been a challenge for professionals, both doctors and speech therapists, and current treatments consist of neuropharmacological therapies, neurosurgical procedures, speech therapy through the approach Lee Silverman Voice Treatment (LSVT® LOUD), which generated data of efficacy and success in the treatment of voice and speech disorders in this population[8], or a combination of methods[9,10]
Results obtained in PEED-BR[12] have regular correlation with the scores of Escala de Sintomas Vocais (ESV)[11] and Vivendo com Disartria (VcD)[15] (Table 4), indicating that having voice-related signs and symptoms and problems in communication does not take the patient to use more coping strategies
Summary
Parkinson’s disease (PD) is a disorder that causes problems widely described in bodily engines such as bradykinesia, rigidity and resting tremor, and affects various subsystems involved in the speech process, by hypokinetic dysarthria[1,2]. Almost 90% of patients have problems related to oral communication[3], but the voice is affected more quickly and more often than other subsystems[4] and can be the initial symptom. Treatment of speech and voice disorders in people with PD has been a challenge for professionals, both doctors and speech therapists, and current treatments consist of neuropharmacological therapies, neurosurgical procedures, speech therapy through the approach Lee Silverman Voice Treatment (LSVT® LOUD), which generated data of efficacy and success in the treatment of voice and speech disorders in this population[8], or a combination of methods[9,10]. There are scientifically proven methods for voice therapy for these individuals, more data on their own perception of voice and communication problem are needed to direct the focus and enhance the therapeutic success
