AbstractA comprehensive functional evaluation designed for patients with chronic low back pain (CLBP) is described. The evaluation includes measures from 4 domains of the CLBP syndrome; physical abilities, level of activity, psychological adjustment and pain perception. New measures for standardized assessment of physical abilities and employment of body mechanics are introduced. Evaluation data from 68 CLBP subjects and 35 age-matched, pain-free, controls is presented. Results indicate important deficits in physical abilities and psychological adjustment for the CLBP group compared to the controls. Factor analysis of the evaluation measures yielded a general conditioning factor and a general psychological adjustment factor but complicated factor structures for report of pain and time in activities. Further analysis demonstrated a strong relationship between objective disability and psychological and psychosocial adjustment but little relationship between level of pain and other disability measures.
