Objective: To estimate the prevalence of musculoskeletal disorders and associated factors in manual physiotherapists and massage therapists who apply the massage technique. Method: This is a cross-sectional observational study in Metropolitan Lima. The population was 173 people (82 physiotherapists and 91 masseurs) who applied the massage technique on a stretcher. It was used four questionnaries, the Data Collection Questionnaire (DCQ), which included the International Physical Activity Questionnaire (IPAQ) the Nordic Musculoskeletal Specific Questionnaire of Kuorinka and, the Questionnaire on labor productivity and pain deterioration (WPAI questionnaire: PAIN). For the analyzes, it was performed statistical tests of Student's T, U-Mann-Whitney and a generalized linear model with log and poisson family function and robust variances was used for the calculation of raw and adjusted Prevalence Ratios (PR) stratified by profession. Results: The final sample included 82 physiotherapists and 91 masseurs. The total injury prevalence was (143/173) 82.7% [95% CI; 76.2-87.6], which varied among physiotherapists (70/82) 85.4% [95% CI; 75.7-91.6] and masseurs (73/91) 80.2% [95% CI; 70.6-87.3]. The highest percentage of pain or discomfort occurred in the cervical region (physiotherapists: 62.2%-masseurs: 53%) and lumbar (physiotherapists: 46%masseurs 32%). In the labor productivity, physiotherapists are more affected than masseurs (71.43% versus 65.75%) as well as daily living activities (DLA). In the adjusted analysis, no statistically significant results were found. Conclusions: The physiotherapists present a higher prevalence of disorders, a high percentage of pain in the affected areas and an important affection in the labor productivity in this group in comparison to the group of the masseurs.
