The World Health Organization (WHO) classifies driving as a function of daily activities and social participation. Professional bus drivers have an important place in society for transportation. Drivers are seen as a stressful occupational group due to their use of the vehicle in the same position and intensive working hours. It is important for bus drivers not to feel discomfort during long working hours and to choose the right seat position. Because the design of the driver's seat directly affects the driver's spine biomechanics. For an ergonomic posture, the head, back and waist areas of the driver's seats should be well supported. During driving, the waist and back of the seat should be supported in order to fix the driver's lumbar region due to movements in the vehicle seat. Professional drivers' long working hours, sitting positions and exposure to vibration, work stress, short breaks, and insufficient physical activity bring about occupational diseases. Musculoskeletal disorders are seen primarily, as well as hypertension, diabetes, cardiovascular diseases, etc. Most musculoskeletal problems are caused by incorrect sitting positions. In many studies, it is seen that drivers have neck, upper back and waist pain, and spinal problems. The main reason for musculoskeletal disorders is that the seats are not adjustable and most drivers try to maintain their posture with additional supports. When the studies conducted look at the relationship between the driver and the seat during long-term vehicle use, the pressure in the contact areas, insufficient support in the back and waist area causes a decrease in comfort, thus causing back and waist discomfort and pain in the individual. Psychosocial factors are also risk factors affecting musculoskeletal disorders. It has been observed that stress causes various diseases including heart disease, gastrointestinal diseases, and musculoskeletal disorders in city bus drivers. Psychosocial factors such as job satisfaction, burnout, and stress have been found to be associated with the incidence of musculoskeletal disorders. Eliminating the back pain and discomfort of professional drivers, who occupy a large place in society, will provide great benefits both for the health of individuals and to alleviate the burden on the service sector. In studies in the international literature on this subject, only posture analyses of drivers have been conducted or the effects on pain and discomfort in the short term after the intervention have been examined. In the literature, drivers stated that seats with lumbo-sacral support were more comfortable than standard seats. In this study, the effect on pain and discomfort will be examined by following the drivers for 3 months. The aim of this study is to examine the effectiveness of the use of lumbar region support in bus drivers by following them for 3 months in terms of back pain and discomfort caused by long working hours and incorrect posture.
