Patient-Specific Functional Scale

Most participants achieved high PSFS functioning by 4 months postpartum and sustained it at 3 years. The PSFS may capture individual activity limitations missed by standardized pelvic girdle pain questionnaires. Participants selected two activities limited by pelvic girdle pain and rated them repeatedly from inability to unrestricted performance. A full PSFS score at 3 years was reported by less than half of participants, even though average functioning was high. The study used the Patient-Specific Functional Scale to measure functioning in activities personally meaningful to each participant.
