Standardized Nordic Musculoskeletal Questionnaire

The existence and severity of musculoskeletal disorders were assessed through the Standardized Nordic Musculoskeletal Questionnaire, which is divided into two parts. The general part consists of 27 questions with a dichotomous response (Yes/No) about musculoskeletal symptoms both during the past 12 months and the past 7 days. All these questions refer to 5 body regions: neck, shoulders, low back, elbows/forearms, wrists/hands, including a corporal diagram seen from behind. The specific part of the questionnaire delves into the analysis of symptoms in the lumbar, neck, and shoulder regions with a dichotomous response (Yes/No) and with the timing of the problem. In addition, it presents a specific question about the treatment received (Yes/No).[17,18,19]
