A field survey of drivers of late-model vehicles traveling on two Michigan highways was conducted to determine the frequency of discomfort experienced during driving and the relative frequency of the different body regions involved. Two hundred and fifty-two drivers were interviewed with 142 reporting no discomfort and 110 reporting discomfort in at least one body region. Some drivers reported discomfort in more than one body region for a total of 240 responses among the 110 drivers with discomforts. Most discomfort was reported as mild pain and characterized as a dull ache although a significant amount of the discomfort in the neck/shoulder/arm region was also characterized as sharp while in the buttock/hip/thigh region nearly one-half of the discomfort responses were characterized as numbing. Little correlation between vehicle and seat factors and the experience of discomfort was observed with the exception that the no-discomfort group included a higher percent of subjects with power seats and seats with lumbar support, while in the discomfort group, the percentage of subjects with bucket seats (compared to bench seats) was slightly higher.
