Self-perception of insomnia, sleep quality, and musculoskeletal pain in dysphonic women: preliminary study.

Objective: To evaluate the association between musculoskeletal pain, insomnia indices, and sleep quality with voice functioning among women.

Methods: Thirty women aged between 18 and 50 years old participated in two groups: dysphonic group (DG) - composed of 15 women diagnosed with behavioral dysphonia; and control group (CG) - composed of 15 vocally healthy women. All participants answered the Musculoskeletal Pain Investigation Questionnaire, Pittsburgh Sleep Quality Index (PSQI), and Insomnia Severity Index (ISI) questionnaires. Statistical tests were applied to compare groups and to relate outcome variables, with a significance of 5% (p<.05).

Results: Dysphonic women presented a higher frequency of musculoskeletal pain in the posterior neck, lower back, masseter, submandibular, and larynx regions. There was no statistically significant difference for the other compared variables. We observed that there was a difference in the comparison between pain in some head and neck regions and the quality of sleep and evidence of insomnia, both in DG and CG.

Conclusions: Dysphonic women have a higher frequency of pain in the head and neck regions when compared to vocally healthy women. There is a difference between sleep quality, insomnia, and musculoskeletal pain, regardless of the presence of vocal and laryngeal alterations.
