“…Der Gesamt-/Totalwert (T) des VHI hat eine Bewertungsspanne von 0-120 Punkten. Der VHI wird in zahlreichen Studien verwendet, um die Wirkung einer Stimmtherapie zu messen, und hat sich als nützliches Messinstrument zur Bewertung der Stimme etabliert mit einer hohen Sensitivität bei behandlungsbedingten Stimmveränderungen [5,6,7].…”

Zusammenfassung Hintergrund Die Behandlungsansätze für die Stimmtherapie sind vielfältig. Zwei neuere Behandlungsansätze in der Stimmtherapie mit Hilfsgeräten sollen auf ihre Effektivität untersucht und verglichen werden. Die Auswertungen der Behandlungseffekte verschiedener Ansätze sind wichtig für die klinische Beratung und die evidenzbasierte Praxis. Ziel Die Wirksamkeit der Novafon Local Vibration Voice Therapy (NLVVT) und der Water Resistance Therapy (WRT) hinsichtlich der Bewertung mittels Voice Handicap Index (VHI) und seinen Aspekten soll überprüft werden. Design Systematische Literatursuche und Metaanalyse mit Random-Effects-Modell. Datenquellen Die Auswertung der 2 Datenbanken (MEDLINE und CENTRAL) und einer manuellen Suche von Beginn bis zum 19. September 2021. Studienauswahl Jede klinische Gruppenstudie in einem Prä-post-Design, die in englischer oder deutscher Sprache verfasst wurde und die Wirksamkeit von NLVVT oder WRT mittels VHI (funktionelle (F), physische (P) und emotionale (E) Aspekte und der Gesamtwert (T)) bei erwachsenen Stimmpatienten mit einer organischen oder funktionellen Stimmstörung überprüft hat, wurde berücksichtigt. Ergebnisse Fünf geeignete Studien wurden identifiziert (NLVVT n= 22; WRT n= 42). Beide Behandlungsansätze zeigten hochsignifikante Verbesserungen bei allen Aspekten des VHI (p<0,01). Im direkten Vergleich erreichte NLVVT signifikant stärkere Verbesserungen bei VHI-T, VHI-F und VHI-E als WRT (p<0,01). Vergleichbar war die Verbesserung bei VHI-P (p=0,28). Fazit Die subjektive Bewertung nach dem Voice Handicap Index ergab, dass NLVVT und WRT effektive Behandlungsmethoden bei Stimmstörungen sind. Im direkten Vergleich erreichte NLVVT in den meisten VHI-Aspekten stärkere Verbesserungen als WRT.

Recurring exposure to low humidity induces transcriptional and protein level changes in the vocal folds of rabbits

Voice disorders are an important human health condition. Hydration is a commonly recommended preventive measure for voice disorders though it is unclear how vocal fold dehydration is harmful at the cellular level. Airway surface dehydration can result from exposure to low humidity air. Here we have induced airway surface dehydration in New Zealand White rabbits exposed to a recurring 8-h low humidity environment over 15 days. This model mimics an occupational exposure to a low humidity environment. Exposure to moderate humidity was the control condition. Full thickness soft-tissue samples, including the vocal folds and surrounding laryngeal tissue, were collected for molecular analysis. RT-qPCR demonstrated a significant upregulation of MUC4 (mucin 4) and SCL26A9 (chloride channel) and a large fold-change though statistically non-significant upregulation of SCNNA1 (epithelial sodium channel). Proteomic analysis demonstrated differential regulation of proteins clustering into prospective functional groups of muscle structure and function, oxidative stress response, and protein chaperonin stress response. Together, the data demonstrate that recurring exposure to low humidity is sufficient to induce both transcriptional and translational level changes in laryngeal tissue and suggest that low humidity exposure induces cellular stress at the level of the vocal folds.

“…Further studies of the VHI‐30 evaluated the potential reduction of questions, 11‐13 its application to various populations with voice disorders, 14‐22 the relationship to objective measurements, 17,23‐25 test‐retest differences 10,26‐28 and its applicability as screening tool 28 .

Background Treatment approaches for voice therapy are diverse, yet their differential effects are not well understood. Evaluations of treatment effects across approaches are important for clinical guidance and evidence‐based practice. Objective of review To quantify the evidence of treatment effectiveness on the outcome measure Voice Handicap Index with the 30‐items (VHI‐30) from existing randomised controlled/clinical trials (RCT) of voice therapy using the statistical approach of a network meta‐analysis (NMA) with a random effects model. Type of review Meta‐analysis. Search strategy We searched in MEDLINE (PubMed, 1950 to 2019), Embase (1974 to 2019) and Science Citation Index (1994 to 2019) using five key terms. The inclusion criteria were reports of randomised controlled/clinical trials (RCTs) published in English or German which evaluated the effectiveness of a specific voice therapy treatment using VHI‐30 as an outcome measure in adult participants with non‐organic or organic voice disorders. Studies were excluded if participants had been diagnosed with neurological motor speech disorders or who were vocally healthy. Furthermore, no medical, pharmacological or instrumental (eg voice amplification) treatments were considered. Evaluation method The primary outcome variable was VHI‐30 with a score from 0 to 120. The pre‐post treatment change in VHI‐30 scores was an average score of 13 points related to various VHI‐30 test‐retest results. Results We retrieved 464 publications (ie with duplicates) and included 13 RCTs, which evaluated nine interventions, in the final analysis. The most effective intervention with a significant and clinically relevant effect was Stretch‐and‐Flow Phonation (SFP) (mean pre‐post difference −28.37, 95% confidence interval [CI], −43.05 to‐13.68). Resonant Voice (RV), the Comprehensive Voice Rehabilitation Program (CVRP) and Vocal Function Exercises (VFE) also demonstrated significant improvements. Conclusions Of the nine voice interventions identified with the present NMA, SFP, RVT, CVRP, and VFE effectively improved VHI‐30 scores from pre‐ to post‐treatment. SFP proved to be the most significant and clinically relevant treatment. Further contributions of high‐quality intervention studies are needed to support evidence‐based practice in vocology.
