Le nettoyage résidentiel et commercial fait partie de notre routine quotidienne pour maintenir l’hygiène autour de l’environnement. La santé des professionnels impliqués dans ces activités de nettoyage est devenue une préoccupation majeure partout dans le monde. La présente étude examine le risque de troubles musculo-squelettiques chez les nettoyeurs professionnels qui effectuent des tâches de nettoyage des sols.

Background Residential and commercial cleaning is a part of our daily routine to maintain sanitation around the environment. Health care of professionals involved in such cleaning activities has become a major concern all over the world. The present study investigates the risk of musculoskeletal disorders in professional cleaners involved in floor mopping tasks. Methods A cross-sectional study was performed on 132 mopping professionals using a modified Nordic questionnaire. The Pearson correlation test was implemented to study the association of perceived pain with work experience. The muscle strain and postural risk were evaluated by means of three-channel electromyography and real-time motion capture respectively of 15 professionals during floor mopping. Results Regarding musculoskeletal injuries, risk was reported majorly in the right hand, lower back, left wrist, right shoulder, left biceps, and right wrist of the workers. Work experience had a low negative association with MSDs in the left wrist, right wrist, right elbow, lower back, and right lower arm (p < 0.01). Surface EMG showed occurrence of higher muscle activity in upper trapezius and biceps brachii (BB) muscles of the dominant hand and flexor carpi radialis and BB muscles of the nondominant hand positioned at the upper and lower portion of the mop rod, respectively. Conclusion Ergonomic mediations should be executed to lessen the observed risk of musculoskeletal injuries in this professional group of workers. Lisez l’article
