Determinants of vocational disability in patients with low back pain.
Eighty-seven unemployed subjects with low back pain were recruited from an orthopedic back pain clinic and were given a battery of physical and psychologic tests. Subjects were contacted six months later to determine their current compensation status and whether they had returned to work. Age, length of time out of work, how much they had lifted in their previous job, the number of weeks they had been compensated, current activity levels, leg pain, and various psychologic factors significantly differentiated those who worked from those who did not. Physical examination findings and testing of the ability to lift were not significantly related to return to work. It is suggested that demographic, job-related, and psychologic factors should be emphasized, rather than only physical capacity, in the evaluation of vocational potential and the assessment of disability in patients with low back pain.
