Applications of Functional Assessment to Musculoskeletal Disability Evaluation

Abstract

A review of the history of the disability determination for LBP suggests that the early focus upon disability as a direct "effect" of impairment has given way to an updated approach acknowledging the multitude of factors, many of which are subjective, that contribute to an individual's future return to work and disability status. In addition to the evaluation of the underlying impairment and pathology, physicians performing disability evaluations for LBP will be best served when they can assess the individual's functional status, and incorporate that information into their decision regarding the individual's current limitations and prognosis. As discussed above, many of the factors contributing to the evaluation of functional status, including pain, physical functioning, and affective status, are necessarily subjective. Nonetheless, the rehabilitation literature suggests that inclusion of this information into the disability determination using a patient-centered approach may provide the factors that are most potent with respect to patient prognosis and eventual return to work.
