One of the most common medical complaints among drivers is low back pain. Back pain is 2 to 4 times more common in commercial drivers than it is in the general population. Causes of this back pain include extended hours in a seated position, awkward posture, exposure to whole body vibration, lifting and carrying associated with materials handling, and improperly fitting or uncomfortable seat position. Whole body vibration has been extensively studied as a cause of low back pain in truck drivers. European drivers have laws specifically limiting the duration and intensity of their exposure to whole body vibration , but there are no similar restrictions for drivers in the US. A relevant study from 1987 analyzed the mood states and fatigue of patients with episodic low back pain. They found that mood states did not predict the onset of pain, but fatigue followed the onset of pain by about 24 hours. So, according to their work, low back pain was a predictor of fatigue. Low back pain was assessed by the Oswestry Disability Index (ODI). Fatigue was measured by the Brief Fatigue Inventory. Multiple linear regression (MLR) was used to quantify the association between LBP and fatigue.
