Protótipo de aplicativo para terapia vocal: análise por pares / Prototype app for voice therapy: a peer review

RESUMO Objetivo A terapia fonoaudiológica vocal promove mudanças de hábitos relacionados à voz do paciente, assim como sua reabilitação. O fonoaudiólogo pode utilizar desde materiais como figuras até recursos eletrônicos e de informática como instrumentos facilitadores durante esse processo. A tecnologia móvel é atrativa, interativa e presente em tempo quase integral na rotina de parte da população e apresenta-se crescente na área da saúde. Desenvolver um protótipo de aplicativo para terapia vocal, submetê-lo à análise por pares e aprimorar o protótipo inicial a partir das apreciações. Método foi desenvolvido um protótipo do aplicativo Q-Voz com base nas Diretrizes de Interface Humana da Apple. O protótipo foi analisado por sete fonoaudiólogos que atuam na área de voz e, a partir das apreciações, foram realizadas melhorias no produto. Resultados todos os recursos do aplicativo foram considerados muito satisfatórios pela maioria dos avaliadores. Todos os avaliadores consideraram o aplicativo muito útil; referiram acreditar que os pacientes terão mais facilidade em realizar mudanças no comportamento vocal com o aplicativo que sem ele; que usariam esse aplicativo com seus pacientes disfônicos em reabilitação; e consideraram que o aplicativo apresenta ferramentas úteis para o autogerenciamento vocal. A partir das sugestões, foram realizadas seis melhorias no protótipo. Conclusão o protótipo do Aplicativo Q-Voz desenvolvido foi avaliado por sete fonoaudiólogos e aprimorado. Todos os avaliadores afirmaram que usariam o aplicativo com seus pacientes em reabilitação, o que indica que o Aplicativo Q-Voz para dispositivos móveis pode ser considerado uma ferramenta auxiliar para a terapia fonoaudiológica vocal.

ABSTRACT Purpose Voice speech therapy promotes changes in patients’ voice-related habits and rehabilitation. Speech-language therapists use a host of materials ranging from pictures to electronic resources and computer tools as aids in this process. Mobile technology is attractive, interactive and a nearly constant feature in the daily routine of a large part of the population and has a growing application in healthcare. To develop a prototype application for voice therapy, submit it to peer assessment, and to improve the initial prototype based on these assessments. Methods a prototype of the Q-Voz application was developed based on Apple's Human Interface Guidelines. The prototype was analyzed by seven speech therapists who work in the voice area. Improvements to the product were made based on these assessments. Results all features of the application were considered satisfactory by most evaluators. All evaluators found the application very useful; evaluators reported that patients would find it easier to make changes in voice behavior with the application than without it; the evaluators stated they would use this application with their patients with dysphonia and in the process of rehabilitation and that the application offers useful tools for voice self-management. Based on the suggestions provided, six improvements were made to the prototype. Conclusion the prototype Q-Voz Application was developed and evaluated by seven judges and subsequently improved. All evaluators stated they would use the application with their patients undergoing rehabilitation, indicating that the Q-Voz Application for mobile devices can be considered an auxiliary tool for voice speech therapy.

Virtual reality exposure using three-dimensional images for the treatment of social phobia

Objective: To test a potential treatment for social phobia, which provides exposure to phobia-inducing situations via computer-generated, three-dimensional images, using an open clinical trial design. Methods: Twenty-one patients with a DSM-IV diagnosis of social phobia took part in the trial. Treatment consisted of up to 12 sessions of exposure to relevant images, each session lasting 50 minutes. Results: Improvements in social anxiety were seen in all scales and instruments used, including at follow-up 6 months after the end of treatment. The average number of sessions was seven, as the participants habituated rapidly to the process. Only one participant dropped out. Conclusion: This study provides evidence that exposure to computer-generated three-dimensional images is relatively inexpensive, leads to greater treatment adherence, and can reduce social anxiety. Further studies are needed to corroborate these findings.

Comparison of the pain levels of computer-controlled and conventional anesthesia techniques in prosthodontic treatment

OBJECTIVE: The objective of this study was to compare the pain levels on opposite sides of the maxilla at needle insertion during delivery of local anesthetic solution and tooth preparation for both conventional and anterior middle superior alveolar (AMSA) technique with the Wand computer-controlled local anesthesia application. MATERIAL AND METHODS: Pain scores of 16 patients were evaluated with a 5-point verbal rating scale (VRS) and data were analyzed nonparametrically. Pain differences at needle insertion, during delivery of local anesthetic, and at tooth preparation, for conventional versus the Wand technique, were analyzed using the Mann-Whitney U test (p=0.01). RESULTS: The Wand technique had a lower pain level compared to conventional injection for needle insertion (p<0.01). In the anesthetic delivery phase, pain level for the Wand technique was lower (p<0.01). However, there was no difference between the Wand and conventional technique for pain level during tooth preparation (p>0.05). CONCLUSIONS: The AMSA technique using the Wand is recommended for prosthodontic treatment because it reduces pain during needle insertion and during delivery of local anaesthetic. However, these two techniques have the same pain levels for tooth preparation.

Osteotomía tibial proximal valguizante planeada por computadora y asistida con guía ciega. Reporte preliminar de diez casos / Valgus proximal tibial osteotomy planned by computer and performed by a blind guide. Preliminary report of ten cases

Se presentan los resultados del diseño de una guía ciega para efectuar la osteotomía tibial alta valguizante de rodilla, misma que fue planeada usando equipo de cómputo y programas manipuladores de imágenes. En una serie de diez pacientes se concluye que al igual que otros trabajos publicados con otras guías, el procedimiento es más seguro y mucho más predecible
