What Factors Determine the Use of Volitional and Non-Volitional Devices in Vocal Interventions Performed by Brazilian Speech-Language Pathologists?

To analyze the determining factors for using devices in vocal interventions and characterize their use by Brazilian speech-language pathologists (SLPs). This cross-sectional observational study had a sample of 148 SLPs with clinical practice in voice. They answered an online questionnaire via Google Forms about sociodemographic data, training, work in the area, and the use of devices in vocal interventions. Data were analyzed descriptively and inferentially. Tubes, straws, and masks were the most commonly used devices. SLPs specializing in voice are more inclined to use thermotherapy and kinesio tapings while being less inclined to use therapeutic ultrasounds and nebulizers. Voice specialists are less likely to employ electrostimulation. The choice to use photobiomodulation and auditory monitoring devices is influenced by the years of clinical experience, whereas the speech-language therapy training duration affects the use of electrostimulation. The age of the professional also plays a role in the utilization of vibratory stimulation. Vibratory stimulation, auditory monitoring devices, thermotherapy, and nebulization are more frequently utilized among individuals who rely on their voices for occupational purposes, whereas electrostimulation is less common. The use of photobiomodulation is infrequent in children; vibratory stimulation is more common in adolescents, and thermotherapy is relatively common among older individuals. Most of these devices are typically prescribed in execution time during vocal intervention. The specialization, the time since graduation and in the occupation, and the target population of the service are the determining factors for the use of devices. They are used in vocal therapy and training, targeting vocal function.
