“…Like acoustical parameters, aerodynamic parameters showed similar trends according to the timing after IL. This finding tended to be precisely consistent with the .006 G, grade; R, roughness; B, breathiness; A, asthenia; S, strain; NHR, noise harmonic ratio; CPP, cepstral peak prominence; MPT, maximum phonation time; MFR, mean airflow rate; VHI, voice handicap index closed quotient (the ratio between the closed glottal phase duration and the fundamental period) and the VHI-30 (self-assessment questionnaire that evaluates the level of handicap caused by hoarseness) [21,22]. These results demonstrated that subjective satisfaction, voice quality, and intensity peak around 3 months after IL, which is the estimated half-life of HA in vocalis muscles.…”

Background and Objectives This study aimed to evaluate the clinical efficacy and safety of hyaluronic acid (HA) (The Chaeum Premium No.2®) for injection laryngoplasty (IL) in unilateral vocal cord paralysis (UVCP) patients.Materials and Method This clinical trial has been registered with the clinical research information service of the Republic of Korea (No. KCT0007597). Ten patients with UVCP were enrolled. Auditory-perceptual evaluation, acoustic analysis, aerodynamic analysis, electroglottography, laryngoscopy, and voice handicap index (VHI)-30 were assessed before injection, at 1, 3, and 6 months after injection.Results All auditory-perceptual parameters gradually showed statistically significant improvements at 1, 3, and 6 months after injection. Acoustic, aerodynamic parameters, electroglottography, and VHI-30 showed gradual improvements at 1 and 3 months after injection. Then, they showed slight deterioration 6 months after injection. There were no adverse effects in all patients.Conclusion IL using HA is an effective and safe treatment for UVCP patients.

“…Among the procedures for the study of muscle electrical activity are electromyography (EMG) and surface electromyography (SEMG). The former analyzes and records the myoelectric activity of muscle fibers for the diagnosis of neuromuscular diseases, using needle insertion [ 1 ]. SEMG uses surface electrodes, one of which serves as a reference (neutral electrode) located in the vicinity of electrically inactive tissue such as bones or tendons, for example, in our case, as will be described below, in the olecranon, in order to avoid interference.…”

Currently, there is no consensus on the characterization of the human voice. The objective of the present study is to describe the myoelectric behavior of the extrinsic musculature of the larynx in 146 people with normal voice (Spanish speakers), aged between 20 and 50 years old. Different vocal tasks were recorded using a surface electromyograph (SEMG). In all vocal tasks, it was observed that women had higher activation (µV) in the suprahyoid and sternocleidomastoid muscles than men, while men had higher activation in the infrahyoid muscles. SEMG is a valid procedure to help define normal vocal characteristics in the studied population, providing reference values during clinical examination. However, it is necessary to adopt a universal system of assessment tasks and standardized measurement techniques to allow for comparisons with future studies.

“…More than twenty VHI-30 validation studies in different languages have been published. 10 Further studies of the VHI-30 evaluated the potential reduction of questions, [11][12][13] its application to various populations with voice disorders, [14][15][16][17][18][19][20][21][22] the relationship to objective measurements, 17,[23][24][25] test-retest differences 10,[26][27][28] and its applicability as screening tool. 28 The VHI has been used by numerous studies to measure the effect of voice therapy; its sensitivity treatment-associated voice changes have established it as a useful voice assessment tool.…”

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.
