The Effect of Vibration Level, Workload and Long Exposure to the Use of Sewing Machines on Signs of Complaints of Carpal Tunnel Syndrome (CTS) in Workers at the Istana Bordir, Malang

Abstract

Activities that cause vibrations in the machine using the help of hands for a long time are often associated with Carpal Tunnel Syndrome(CTS). Carpal Tunnel Syndrome(CTS) is an occupational disease caused by entrapment of the median nerve through the carpal. Symptom experienced by workers in Istana Bordir are pain and tingling in the hands when working too long. The purpose of this study was to determine the effect of vibration levels, workload and duration of exposure to the use of sewing machines on signs of Carpal Tunnel Syndrome(CTS) symptom in workers in Istana Bordir Malang. This study used an observational analytic research design with a cross sectional design. The research sample amounted to 15 people who were taken based using total sampling technique. The instrument used is a vibration meter, palpation to count the pulse and a questionnaire. Analysis of research results using ordinal logistic regression test. The results of the study can be concluded that the variables that influence the results of the partial logistic regression are working period with a value (sig. 0.035), length of exposure with a value (sig. 0.038), vibration level with a value (sig. 0.039), and workload value is (sig. 0,007). While the results of the logistic regression simultaneously obtained a significant result of 0.006. So it can be concluded that there is an effect of vibration level and duration of exposure to the use of sewing machines on signs of Carpal Tunnel Syndrome(CTS) symptom in workers in Istana Bordir Malang.
