A influencia do programa de ginastica laboral na prevenção dos disturbios osteomusculares relacionados ao trabalho (DORT)




This study aimed to study the effects of workplace stretching program in the flexibility, posture and complaints of osteomuscle pains of workers in a metallurgic industry. It was selected 41 subjects, alI metallurgic workers; 38 males and 3 females, ranging from the age of 17 - 40. Before the procedures some evaluations were taken: a study of their work sites and movements; a questionnaire with open and guided questions to assess complaints of muscle and osteomuscle pains and the most affected segments; a physical, postural and muscular evaluation to study the anterior and lateral flexibility with the Test of Flections and to Get; muscle tension and workers characteristics of posture. The use of gymnastics happened in 2 times: warm-up exercises, 5 minutes before the day of work and compensatory exercises, for 5 minutes during the day of work. The exercises were performed during 10 months and were conducted by multiplication agents chosen by the researcher. After this period of time, it was done another posture and physical evaluation, a new questionnaire with directed questions was applied to evaluate the acceptance of workplace stretching program by the workers and how they feel After the exercises. Loss of workers was accounted due to demissions and 30 of the subjects were until the end of this study. The statistical analysis was descriptive using tables of frequencies for categoric variables and positioning measures and dispersoon for continual variables and the results of tests before and After the program were compared. The test used were test of McNemar, Stuart-Maxwell and paired Wilcoxon according with the variable analyzed. The results found are as it follows: there was no changein the posture of the participants After the workplace stretching program; the complaints of pain decreased and a significant number of participants became assimptomatic and a significant number of participants decresead the number of segments with pain. It also was found significant improvement in anterior flexibility, a tendency of improvement in the lateral flexibility and improvement in the muscular tension. Finally it also was found great acceptance of workplace stretching program by the workers and companie managers. It was concluded that workplace stretching program increased the flexibility, the relaxation and thus decreased the complaints of muscular pains, being able to promote especific prevention of DORT. But this is not sufficient and it is also necessary to integrate factors related to organization, ergonomyand individual in order to prevent DORT
