Pengaruh Bob Anderson Stretching terhadap Penurunan Keluhan Carpal Tunnel Syndrome pada Penjahit di CV. Sumatera Agung Makmur Konveksi Medan

Abstract

Carpal Tunnel Syndrome (CTS) is one of the most common occupational diseases among informal sector workers such as tailors, resulting from repetitive hand movements, non-ergonomic working positions, and a lack of preventive interventions. This study aims to analyze the effect of Bob Anderson stretching on reducing CTS complaints in tailors at CV. Sumatera Agung Makmur Konveksi Medan. This study uses a one-group pretest-posttest design with a sample size of 32 tailors selected through purposive sampling. The intervention was conducted over four weeks, three times a week, with a total of thirteen hand, wrist, and forearm stretching exercises. CTS complaint measurement was performed using the Boston Carpal Tunnel Questionnaire (BCTQ) instrument and analyzed using the Simple Linear Regression Test according to the data distribution. The research results show that there is an influence between the number of intervention weeks and CTS symptoms (p = 0.001; R2 = 0.181), meaning that the duration of stretching intervention contributes 18.1 percent to predicting a decrease in CTS symptoms in tailors. This indicates that each additional week of intervention can reduce the CTS score by 2.144 per week, with a 95% confidence interval ranging from -2.949 to -1.338. It can be concluded that the duration of the intervention has a negative and significant effect on the reduction of the CTS score. Bob Anderson Stretching should be applied regularly in the work activities of tailors as an effort to prevent muscle and nerve disorders caused by static and repetitive work. The owner of the garment factory is required to provide special time during working hours for stretching exercises. This program must be implemented for a minimum of nine weeks or 27 interventions and continued while working as a tailor to prevent the recurrence of CTS symptoms. Future researchers can evaluate the effectiveness of stretching if performed for nine weeks or 27 interventions, as predicted by the regression equation that a clinically significant reduction in CTS symptom scores is achieved with that number of interventions.
