Abstract

Barbers face irregular work schedules, infrequent breaks, and uncomfortable postures, contributing to pain and
fatigue due to ergonomic risks, which affect their quality of life and performance. Therefore, this study aimed to
conduct a biomechanical and ergonomic assessment of barbering activities, using different analytical tools to
identify postural and musculoskeletal risks. The research was conducted in a barbershop located in Mogi Mirim
SP, through direct observation, photographic records, and video recordings of three workers. Postures were
analyzed using the REBA, RULA, NBR ISO 11226:2013, and NBR ISO 11228-3:2014 methodologies. The results
revealed a high ergonomic risk in the evaluated postures, especially due to prolonged standing, repetitive
movements, and insufficient rest periods. The REBA and RULA tools proved efficient for rapid analyses, while the
ISO standards provided a more detailed and precise diagnosis of risk factors. It is concluded that the integrated
application of these methodologies is essential to support effective ergonomic interventions, contributing to the
prevention of musculoskeletal disorders and to the promotion of barbers’ occupational health.
