The Influence of Age, Gender, Health-Related Behaviors, and Other Factors on Occupationally Relevant Health Complaints of Singers

Population characteristics and self-assessment of speaking and singing voice in Polish contemporary commercial music singers-an exploratory, cross-sectional study

Background

The domination of the Contemporary Commercial Music (CCM) industry in music markets has led to a significant increase in the number of CCM performers. Performing in a wide variety of singing styles involves exposing CCM singers to specific risk factors potentially leading to voice problems. This, in turn, necessitates the consideration of this particular group of voice users in the Occupational Health framework. The aim of the present research was threefold. First, it sought to profile the group of Polish CCM singers. Second, it was designed to explore the prevalence of self-reported voice problems and voice quality in this population, in both speech and singing. Third, it aimed to explore the relationships between voice problems and lifetime singing involvement, occupational voice use, smoking, alcohol consumption, vocal training, and microphone use, as potential voice risk factors.

Materials and methods

The study was conducted in Poland from January 2020 to April 2023. An online survey included socio-demographic information, singing involvement characteristics, and singers' voice self-assessment. The prevalence of voice problems was assessed by the Polish versions of the Vocal Tract Discomfort Scale (VTDS) and the Singing Voice Handicap Index (SVHI). Also, a self-reported dysphonia symptoms protocol was applied. The perceived overall voice quality was assessed by a Visual Analogue Scale (VAS) of 100 mm.

Results

412 singers, 310 women and 102 men, completed the survey. Nearly half of the studied population declared lifetime singing experience over 10 years with an average daily singing time of 1 or 2 h. 283 participants received vocal training. For 11.4% of respondents, singing was the primary income source, and 42% defined their career goals as voice-related. The median scores of the VTDS were 11.00 (0-44) and 12.00 (0-40) for the Frequency and Severity subscales, respectively. The median SVHI score of 33 (0-139) was significantly higher than the normative values determined in a systematic review and meta-analysis (2018). Strong positive correlations were observed between SVHI and both VTD subscales: Frequency (r = 0.632, p < 0.001) and Severity (r = 0.611, p < 0.001). The relationships between most of the other variables studied were weak or negligible.

Conclusion

The examined CCM singers exhibited substantial diversity with regard to musical genre preferences, aspirations pertaining to singing endeavors, career affiliations, and source of income. Singing voice assessment revealed a greater degree of voice problems in the examined cohort than so far reported in the literature, based on the SVH and VTDS.

Clinical Characteristics of Individuals Presenting to Physiotherapy for Voice and Throat Care: A Retrospective Case Notes Review

BACKGROUND

Currently, little is known about the characteristics of individuals presenting for physiotherapy care with voice and throat problems.

PURPOSE

The aim of this study is to describe the demographic and clinical characteristics of individuals presenting to physiotherapy for voice and throat-related problems, and to use this information to clarify the role of physiotherapy in the management of people with voice and throat problems.

METHODS

A retrospective clinical case notes review was conducted of all clients who accessed physiotherapy for voice and throat problems at a private practice based in Christchurch within a 12-month period from 1st October 2020 to 1st October 2021.

RESULTS

Data were analyzed from 53 patient charts. The typical profile of an individual accessing physiotherapy for voice and throat problems were female (n = 37), NZ European (n = 26), singer (n = 43), with chronic problems (n = 20), of a nontraumatic origin (n = 45). Voice problems were present in 39 cases and muscle-related problems were present in 42 cases. Treatment primarily included manual therapy and various modes of exercise therapy.

CONCLUSIONS

The clinical characteristics described offer insight into the demographic and clinical characteristics of individuals accessing physiotherapy services for voice and throat problems. A high prevalence of muscle-related problems and wider issues were identified, consistent with the physiotherapy skill set. Physiotherapy appears to complement existing ENT or SLT services by identifying and managing muscle-related voice problems and addressing wider factors contributing to voice and throat problems.
