PURPOSE
This systematic review appraises and summaries methodology documented in studies using high resolution pharyngeal manometry (HRM) with and without impedance technology (HRIM) in adult populations.
METHODS
Four electronic databases CINAHL, EMBASE, MEDLINE, and Cochrane Library were searched up to, and including March 2017. Studies reporting pharyngeal HRM/HRIM for swallowing and/or phonatory assessment, published in peer-reviewed journals in English, German, or Spanish were assessed for the inclusion criteria. Of the selected studies, methodological aspects of data acquisition and analysis were extracted. Publications were graded based on their level of evidence and quality of methodological aspects was assessed.
RESULTS
Sixty-two articles were identified eligible, from which 50 studies reported the use of HRM and 12 studies used HRIM. Of all included manuscripts, the majority utilized the ManoScan™ system (64.5%), a catheter diameter of 4.2 mm was most prevalently documented (30.6%). Most publications reported the application of topical anesthesia (53.2%). For data analysis in studies using HRM, software intrinsic to the recording system was reported most frequently (56%). A minority of the studies using HRM provided data about measurement reliability (10%). This is higher for studies using HRIM (50%).
CONCLUSIONS
Considerable methodological variability exists regarding data acquisition and analysis in published studies using HRM/HRIM. Lacking reports of methodology make study replications difficult and reduce the comparability across studies. More data regarding the impact of individual methodological aspects on study outcomes are further required for the development of methodological recommendations.

Review
OBJECTIVES
This systematic review aims to explore the effectiveness of voice health education interventions among singers, particularly focusing on vocal hygiene treatment programs tailored for professional voice users.
STUDY DESIGN
Systematic review.
METHODS
Preferred Reporting Items on Systematic Reviews and Meta-Analysis guidelines were followed to conduct this systematic review. Comprehensive searches were conducted in PubMed, Web of Science, Scopus, Science Direct, and Cochrane Library databases. Four articles were selected for detailed review. The studies were evaluated using the Effective Public Health Practice Project tool for quality assessment.
RESULTS
The four reviewed studies primarily utilized the pretest-posttest design to examine the effectiveness of vocal hygiene interventions on singers' vocal health. Two studies investigated the effect of hydration as a treatment method, while the remaining two focused on vocal hygiene instruction. Significant improvements were observed in various vocal health parameters, including maximum phonation time, intensity, Dysphonia Severity Index, and number of daily vocal breaks taken.
CONCLUSION
This systematic review provides valuable insights into the efficacy of vocal hygiene treatment programs for singers. The positive outcomes observed in the reviewed studies underscore the importance of voice health education tailored to singers' specific needs. However, the limited number of eligible studies and the common limitation of small sample sizes highlight the need for further research in this area. Vocal health practitioners, educators, and researchers can utilize the findings of this review to develop evidence-based vocal hygiene interventions that promote the well-being and longevity of singers' vocal performance careers.

Meta-Analysis
PURPOSE
We aimed to determine whether voice rehabilitation after radiotherapy improves the quality of life (QOL), voice function, and self-rated voice function in patients with laryngeal cancer.
METHODS
We searched CENTRAL, MEDLINE, EMBASE, PEDro, and World Health Organization International Clinical Trials Registry Platform for randomized controlled trials published between inception and October 2018. The primary outcome was QOL, adverse events and mortality. Secondary outcomes included voice function and self-rated voice function. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation approach.
RESULTS
Three trials (enrolling 122 patients) compared voice rehabilitation to usual care or no intervention after radiotherapy. Voice rehabilitation did not significantly improve any QOL scores. Data on adverse events and mortality were not available in any of the trials. Voice rehabilitation did not improve any voice function scores, such as jitter (mean difference: - 0.48 [- 1.27 to 0.32]), shimmer (mean difference: - 0.04 [- 0.27 to 0.19]), maximum phonation time (mean difference: 1.54 [- 1.13 to 4.22]), and the grade, roughness, breathiness, asthenia, and strain scale (mean difference: - 0.39 [- 2.59 to 1.80]). Voice rehabilitation also did not improve the voice handicap index, which was used as a self-rated voice function score (mean difference: 5.54 [- 2.07 to 13.16]). The certainty of the evidence was graded as low for primary and secondary outcomes.
CONCLUSION
Voice rehabilitation for patients with laryngeal cancer after radiotherapy might not improve QOL, voice function, and self-rated voice function. Pre-specified voice rehabilitation programs may not be necessary for all patients with laryngeal cancer after radiotherapy.

Review
BACKGROUND
Obesity is a multifactorial chronic disease involving multiple organs, devices, and systems involving important changes in the stomatognathic system, such as in the orofacial muscles, temporomandibular joint, cheeks, nose, jaw, maxilla, oral cavity, lips, teeth, tongue, hard/soft palate, larynx, and pharynx. Patients with obesity indicated for bariatric surgery reportedly presented with abnormalities in the structures and function of the stomatognathic apparatus. This occurs through the accumulation of adipose tissue in the oral cavity and pharyngeal and laryngeal regions. Therefore, this systematic review aimed to elucidate the changes occurring in the stomatognathic system of patients with obesity after undergoing bariatric surgery.
METHOD
Information was searched based on the equations developed with the descriptors obtained in DECS and MESH using the PRISMA methodology. Studies published between 2010 and October 2021 in databases including PubMed, ProQuest, Scielo, Dialnet, EBSCO, and Springer Link were considered.
RESULTS
Eighty articles met the inclusion criteria after evaluating the articles, thereby allowing for the determination of the morphophysiological correlation of the stomatognathic system with the population studied. At the morphological or structural level, changes were observed in the face, nose, cheeks, maxilla, jaw, lips, oral cavity, teeth, tongue, palate, temporomandibular joint, neck, muscles, head, shoulders, larynx, and pharynx. At the morphological level, the main changes occurred in, and the most information was obtained from, the labial structures, teeth, muscles, pharynx, and larynx. Physiological changes were in breathing, phonation, chewing, and swallowing, thereby revealing the imbalance in basic and vital functions.
CONCLUSIONS
Analyzing the changes and structures of obese patients and candidates for bariatric surgery revealed that, in the preoperative period, the evidence is clear owing to the presence of a wide range of information. However, the information is more limited regarding the postoperative period; thus, further research focusing on characterization of the system postoperatively is warranted.

Meta-Analysis
Purpose Our aim was to assess the different voice prostheses (VPs) to identify the most efficient, safest, patient-tailored, longest lifetime, and inexpensive VPs and assess the different factors affecting their quality. Method In September 2017, 15 databases were searched to include all randomized controlled trials. A new search was done in May 2019 to include all other study design articles, which include all the new-era VPs subtypes. Network meta-analysis (NMA) was applied to all 27 outcomes, besides NMA overall and partial order setting was done by using Hasse scatter plots. values were used in NMA, where the best VPs are approaching one and the least approaches zero. Meta-analysis was done for the rest of the outcomes. Results Two hundred one articles were eligible for inclusion in our study ( = 11,918). Provox-2 was significantly the most efficient and safest device concerning the most patient preference (odds ratio [] = 33.88 [0.65, 1762.24]; = .92), the least dislodgement (risk ratio [RR] = 0.27 [0.13, 0.57]; = .79), the least airflow resistance (RR = 0.42 [0.08, 2.11]; = .84), the least granulation formation (RR = 0.73 [0.02, 26.32]; = .60), and the least VPs' inaccurate size (RR = 0.77 (0.23, 2.61); = .66). Heat and moisture exchanger addition showed a significant increase in maximum phonation time and breathing experience, with values (1 and .59), respectively. While heat and moisture exchanger addition showed a significant decline in stoma cleaning frequency, coughing frequency, forced expectoration, sputum production, sleeping problems, and loosening of adhesive, with values (.99, .72, .69, .96, 1, and 0.96), respectively, Groningen low resistance and Nijdam were considered the worst devices with both overall mean value of .44. Conclusions Provox-2 is considered the best choice as being the most preferable for patients, with the least airflow resistance, dislodgment, granulation formation, and prosthesis inaccurate size. Groningen low resistance and Nijdam were considered the worst devices according to our analysis. Supplemental Material https://doi.org/10.23641/asha.14802903.

PURPOSE
Considering the conceptual migration from vocal load and vocal loading to vocal demand and vocal demand response, this review of literature aimed to identify physiological explanations, reported measurements, and associated factors (vocal demands) reported in the literature when considering the phonatory response to a vocal demand.
METHODS
A systematic review of literature, following the PRISMA Statement, was conducted using Web of Science, PubMed, Scopus, and ScienceDirect. Data were analyzed and presented in two parts. First, a bibliometric analysis, co-occurrence analysis, and content analysis were performed. Three criteria that got article inclusion were defined: (1) written in English, Spanish, and Portuguese; (2) published between 2009 and 2021; and (3) focused on vocal load and loading, vocal demand response, and voice assessment parameters. A total of 54 publications met the criteria and were included in this review. The second part included a conceptual framework based on the content analysis of three aspects of vocal demand response: (1) physiological explanations, (2) reported measurements, and (3) vocal demands.
RESULTS AND CONCLUSION
As would be expected since vocal demand response is a relatively new term and not yet commonly used in literature when discussing way that the speakers respond to communicative scenarios, most of the studies reviewed (both historical and recent) still use the term of vocal load and vocal loading. Although there is a broad variety of literature discussing a wide range of vocal demands and voice parameters used to characterize the vocal demand response, results show that there is consistency across the studies. While vocal demand response is unique and intrinsic to the talker, associated factors that contribute to this response include both internal talker and external talker factors. Internal factors include muscle stiffness, viscosity in the phonatory system, vocal fold tissue damage, elevated sound pressure levels during occupational voice demands, extended periods of voice use, suboptimal body posture, difficulties in breathing technique, and sleep disturbances. Associated external factors include the working environment (noise, acoustics, temperature, humidity). In conclusion, although vocal demand response is intrinsic to the speaker, the speaker's response is affected by external vocal demands. However, due to the wide methods to evaluate vocal demand response, it has been difficult to establish its contribution to voice disorders in the general population and, specifically, among occupational voice users. This literature review identified commonly reported parameters and factors that may help clinicians and researchers define vocal demand response.

Review
OBJECTIVES
Dementia is a progressive condition, affecting increasing numbers of people, characterised by cognitive decline. The current systematic review aimed to evaluate research pertaining to the impact of arts and health interventions on cognition in people with dementia.
METHOD
A literature search was conducted utilising PsychInfo, Cochrane Reviews, Web of Science, Medline and British Humanities Index databases. Seventeen studies were included in the review, including those related to literary, performing and visual arts.
RESULTS
The review highlighted this as an emerging area of research with the literature consisting largely of small-scale studies with methodological limitations including lack of control groups and often poorly defined samples. All the studies suggested, however, that arts-based activities had a positive impact on cognitive processes, in particular on attention, stimulation of memories, enhanced communication and engagement with creative activities.
CONCLUSION
The existent literature suggests that arts activities are helpful interventions within dementia care. A consensus has yet to emerge, however, about the direction for future research including the challenge of measurement and the importance of methodological flexibility. It is suggested that further research address some of these limitations by examining whether the impact of interventions vary depending on cognitive ability and to continue to assess how arts interventions can be of use across the stages of dementia.

Review
PURPOSE
This scoping review aims to synthesize all of the currently available information on how xerostomia correlates with vocal function and the mechanisms that underpin it.
METHODS
Our scoping review used PubMed, Scopus, Embase, and Web of Science databases to review articles published between January 1999 and July 2022 in accordance with the PRISMA-ScR guidelines. In addition to the academic databases, we also conducted a manual search of Google Scholar. Further investigation was conducted on studies that examined the relationship between xerostomia and vocal function.
RESULTS
Of the 682 initially identified articles, 21 met our inclusion criteria. Among the included studies, two articles (n = 2) revealed the mechanistic relationship between xerostomia and vocal function. Most studies (n = 12) focused on xerostomia secondary to other underlying conditions or treatments, among which radiotherapy and Sjögren's syndrome were commonly investigated. Seven studies (n = 7) provided details about common vocal parameters measured in studies of xerostomia and the voice.
CONCLUSION
The literature currently lacks publications regarding the relationship between xerostomia and vocal function. Most of the studies included in this review were about xerostomia secondary to other conditions or medical treatments. Therefore, the impacts on the voice that were observed were very multifaceted and the role of xerostomia alone in phonation could not be ascertained. Nevertheless, it is clear that dryness in the mouth plays some role in vocal function and further research should focus on clarifying and finding the underlying mechanism behind this relationship by incorporating high-speed imaging and cepstral peak prominence analyses.

Review
OBJECTIVE
Reliable voice range profiles are of great importance when measuring effects and side effects from surgery affecting voice capacity. Automated recording systems are increasingly used, but the reproducibility of results is uncertain. Our objective was to identify and review the existing literature on test-retest accuracy of the automated voice range profile assessment.
STUDY DESIGN
Systematic review.
DATA SOURCES
PubMed, Scopus, Cochrane Library, ComDisDome, Embase, and CINAHL (EBSCO).
METHODS
We conducted a systematic literature search of six databases from 1983 to 2016. The following keywords were used: phonetogram, voice range profile, and acoustic voice analysis. Inclusion criteria were automated recording procedure, healthy voices, and no intervention between test and retest. Test-retest values concerning fundamental frequency and voice intensity were reviewed.
RESULTS
Of 483 abstracts, 231 full-text articles were read, resulting in six articles included in the final results. The studies found high reliability, but data are few and heterogeneous.
CONCLUSION
The reviewed articles generally reported high reliability of the voice range profile, and thus clinical usefulness, but uncertainty remains because of low sample sizes and different procedures for selecting, collecting, and analyzing data. More data are needed, and clinical conclusions must be drawn with caution.

Meta-Analysis
PURPOSE
Since new evidence regarding the impact of Wendler glottoplasty (WG) on the voice in transgender women became available in the literature in recent years, we aimed to perform an updated systematic review and meta-analysis to determine the actual safety and efficacy of WG in the process of vocal feminization.
METHODS
PubMed, Embase, and Cochrane were searched for English-language articles published until July 4, 2023. Studies were found eligible if they evaluated the impact of WG on the acoustic-aerodynamic measures and quality of voice in transgender women.
RESULTS
Twenty-three studies were identified. After exclusion of three studies due to incomplete data, 20 studies including 656 patients were included in the meta-analysis. After WG, there was a significant increase of fundamental frequency, speaking fundamental frequency, and lower limit of the frequency range (p < 0.001). Concurrently, a significant reduction of frequency range and maximum phonation time was observed (p < 0.001). No significant differences were found between the pre- and postoperative values regarding the Grade, Roughness, Breathiness, Asthenia, and Strain scale score (p = 0.339). The overall score in the Trans Woman Voice Questionnaire (TWVQ) significantly improved after WG (p < 0.001).
CONCLUSIONS
WG is an effective voice feminization method in transgender women, associated with a high procedural success and low risk of postoperative complications. Significantly improved TWVQ score after surgery suggests its positive impact on the voice-related quality of life. Postoperative decrease of maximum phonation time and frequency range does not seem to significantly impact the effectiveness of voice production.
