20.500.12556/RUL-178089 Effectiveness of group voice therapy in teachers with hyperfunctional voice disorder Background/Objectives: The aim of this study was to assess the short-term and long-term effectiveness of group voice therapy in changing vocal behaviour and improving voice quality (VQ) among teachers with hyperfunctional voice disorders (HFVD), using both subjective and objective measures. Methods: Thirty-one teachers participated in a structured group voice therapy programme. Participants underwent videoendostroboscopic evaluation of laryngeal morphology and function, perceptual assessment of voice, acoustic analysis of voice samples, and aerodynamic measurements of phonation. Patients’ self-assessment of VQ and its impact on quality of life were measured using a Visual Analogue Scale (VAS) and the Voice Handicap Index-30 (VHI-30). Evaluations were conducted at four time points: pre-therapy (T0), immediately post-therapy (T1), and at 3-month (T3) and 12-month (T12) follow-up visits. Results: Significant improvement was observed between T0 and T1 in perceptual voice evaluations: grade, roughness, asthenia, strain, loudness, fast speaking rate, as well as in neck muscle tension, shimmer, patients’ most harmful vocal behaviours, VHI-30 scores, patients VQ evaluation, and its impact on quality of life (all p < 0.05). Almost all parameters of subjective and objective voice assessment improved over the 12-month observation period, with the greatest improvement between T0 and T12 (all p < 0.05), indicating lasting reduced laryngeal tension and improved phonatory efficiency. Conclusions: Group voice therapy has been shown to be an effective treatment for teachers with HFVD, leading to significant and long-lasting improvements in perceptual, acoustic, and self-assessment outcomes. Therapy also promoted healthier vocal and lifestyle behaviours, supporting its role as a successful and cost-effective rehabilitation and prevention method for occupational voice disorders. voice disorders teacher voice therapy group therapy treatment outcomes true false true Angleški jezik Ni določen Članek v reviji 2026-01-18 04:22:13 2026-01-19 18:44:21 2026-04-02 14:02:53 0000-00-00 00:00:00 2026 0 0 13 str. iss. 1 Vol. 16 Jan. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616 2039-7283 10.3390/clinpract16010016 265017091 RAZ_Prebil_Natasa_2026.pdf RAZ_Prebil_Natasa_2026.pdf 1 21862F56E100C8612FA7E0338EE3A17D 462da50607fe37bc2f994dbcbdb30081d9a3615507d9f6960e835f746a8a191c c72d5052-f55d-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225717 https://www.mdpi.com/2039-7283/16/1/16 0 d8a2bc20-f41c-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225622 Medicinska fakulteta 0 0 0
