Patient-completed questionnaire giving a percentage of disability during every day activities (activities of daily living sub scale) or sports (sports activity sub scale).  The lower the percentage, the higher the disability.

Intended Population

Method of Use

This is a self-report measure that is broken down into two categories (ADL and SAS) that rates percieved disability with 5 being "no difficulty" and 0 being "unable to perform".
