Title Lung function and surface electromyography of intercostal muscles in cement mill workers
Bibliographic information 2002, Vol.15, No.3, p.279-287. 48 ref.
Abstract This study of cement industry workers used spirometry and surface electromyography (SEMG) of intercostal muscles for measuring pulmonary impairment. A group of 50 healthy male cement mill workers aged 20-60 years with exposure of 13 years on average, were randomly selected, together with 50 controls matched by age, height, weight and socioeconomic status. The results demonstrated statistically significant reductions in forced vital capacity (FVC), forced expiratory volume in first second (FEV), peak expiratory flow (PEF), and maximum voluntary ventilation (MVV) in cement workers compared with controls. Also, the FEV1/FVC ratio was higher in cement workers, while the values of the parameters obtained from SEMG of intercostal muscles were lower. It is concluded that exposure to cement dust not only impairs lung function but also affects intercostal muscle performance.
