Quality of life in dental hygienists using complementary alternative medicine approaches for work-related musculoskeletal disorders

Objectives The use of conventional treatment for work-related musculoskeletal disorders (WRMSDs) reduces the prevalence of pain, but with popularity of complementary alternative medicine (CAM) therapies for treatment, it is important to explore their use and impact on dental hygienists (DHs) quality of life (QoL). Methods A cross-sectional survey research design was used with a non-probability sample of dental hygienists (n = 85) with WRMSDs who used CAM therapies. The WHOQOL-BREF was used to assess quality of life and compared with CAM use and frequency. Analysis included descriptive, t-tests, correlation and chi-square tests of independence. Results The most commonly used CAM types were massage (81%) and chiropractic manipulation (67%) with 66% of respondents using two or more CAM therapies. Participants using five or less different CAMs (n = 46), compared with those using more than five CAM types (n = 35, M = 2.3, SD = 1.5), t (79) = 2.7, p = 0.01, had a higher average number of years before they noticed their WRMSD (M = 3.3, SD = 1.9). Participants reporting use of a higher number of CAM types also had lower QoL physical health domain scores (rho = -0.2, p = 0.03). Conclusions Dental hygienists used a variety of CAM approaches to manage WRMSDs and had a lower QoL across all domains (physical health, psychological health, social relationships and environment) than the normative mean. More research is needed to explore the use of CAM approaches, such as yoga, for prevention and management of WRMSDs to improve QoL.
