Evaluation of Physical Symptoms in Brazilian Conductors Through NMQ and DASH Instruments.

Abstract

Few studies have investigated populations of conductors concerning their activity in general or work-related health aspects, although these individuals also face important work demands with the potential for develop¬ing hearing, physical, and vocal problems. This study was designed to assess physical symptoms (pain, tingling, numbness) in Brazilian conductors by applying the Nordic Musculoskeletal Questionnaire (NMQ) and the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire. The data were collected online from 166 Brazilian conductors who were actively working for at least 1 year. The NMQ results indicated a high prevalence of symptoms in the shoulder, neck, and lumbar and upper back regions. Participants also complained of pain in the upper limbs, especially on the right side, and spinal regions associated with conducting. Bivariate statistical tests indicated significant relationships between the presence of symptoms in the upper limbs and higher disability scores in the DASH instrument. The body regions mentioned by the participants are similar to those reported in the few studies of conductors in the literature, highlighting that conducting has a specific physical impact and the potential to affect the function of the upper limb in the conductors' daily activities.
