Disability - How successful are we in determining disability?

Individuals who have set ere back pain have trouble bending, may not be able to put on their shoes, have difficulty in ambulation, and may not be able to clean their own houses. What distinguishes these individuals with low back pain from those afflicted with other conditions (i.e., congestive heart failure, metastatic cancer, symptomatic acquired immune deficiency syndrome) is prognosis. Back pain essentially never shortens life. Acute back pain has a very benign prognosis, with more than 90% of the individuals returning to functional status equivalent to their baseline status within 3 months of the onset of pain. Patients who have chronic back pain have a significantly worse prognosis, but most cohort studies show that substantial numbers of chronic back pain patients improve over time with supportive therapy.
