Functional disability assessment.

The widespread introduction of computers into clinical settings has increased the feasibility of conducting comprehensive functional disability assessment. The Functional Status Questionnaire (FSQ) is a brief, self-administered questionnaire designed to facilitate clinical assessment of functional disability. The FSQ items can be scored by computer using a simple algorithm and summarized into disability index scores. These scales have alpha reliability coefficients of .64 to .82 and substantial convergent validity when used with primary care patients. Disability assessment tools like the FSQ can be adapted easily for clinical use by physical therapists.
