Objective. The following research questions were posed: (1) Does participatory ergonomic education and programming influence occupational performance among cosmetologists? (2) Does ergonomic education and programming influence quality of life among cosmetologists? (3) Does ergonomic education and programming influence pain among cosmetologists? (4) Does ergonomic education and programming influence numbness and tingling in the upper extremities of cosmetologists? The purpose of this study was to: (1) implement a participatory ergonomic program for cosmetologists and (2) to examine the effectiveness of the implemented program in decreasing signs and symptoms associated with work-related musculoskeletal disorders.

Method. A multiple baseline, single subject design was used. Data were collected from seven subjects for a total of 12 weeks. The intervention was introduced to subjects at different times throughout the study and consisted of general ergonomic education, a participatory ergonomic interview session, and basic range of motion stretches. Outcome measures included the QuickDASH, a 10-point pain scale, and a 10-point numbness and tingling scale. Data were analyzed using visual analysis techniques including the two-standard deviation band method and the binomial test method. Data trends were assessed to further support the results.

Results. The results of this study indicate that ergonomic programming improved occupational performance, improved quality of life, decreased upper extremity pain, and decreased upper extremity numbness and tingling for several of the participants. The results of this study also produced statistically significant changes in QuickDASH scores indicating improved quality of life and improved occupational performance. Statistically significant change in pain scores and numbness/tingling scores indicated that several participants experienced decreased pain, numbness, and tingling in the upper extremity.

Conclusion. The results of this study support the assumption that cosmetologists experience symptoms consistent with work-related musculoskeletal disorders and respond to participatory ergonomic programming similar to other working groups. The results of this study support the main principles of the participatory ergonomic approach which focus on involvement of the worker. The participatory ergonomic approach used in this study aligns with the client-centered principles found in the practice of occupational therapy and therefore provides evidence of effective occupational therapy intervention.
