Description
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 usculoskeletal 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.
