Continuous sitting and standing tolerance was measured by: (1) covert observation of 154 patients with chronic back pain and (2) blinded expert physician prediction based on complete history and physical examination. One hundred twenty-four of the 154 patients (80.5 percent) were able to sit continuously for 60 minutes or more and to stand continuously for 30 minutes or more while being covertly observed. Physician prediction showed poor correlation to covert observation for sitting and standing tolerance. Overall, physicians under-predicted the ability to sit 60 or more minutes and to stand 30 or more minutes.
