This study aimed to determine long-term functional and psychosocial implications of PS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients underwent strength testing of their affected limb by comparing with their contralateral arm. They completed Disabilities of the Arm, Shoulder, and Hand (DASH), 36-item Short-Form Health Survey (SF-36), and several Patient-Reported Outcome Measurement Information System (PROMIS) surveys. Aggregate scores were compared with population norms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty-eight patients were enrolled, and 16 returned for strength testing. The average age was 42 years (range, 18-65 years), and the average follow-up was 25 years (range, 1-52 years). Dynamometer testing showed decreased strength in shoulder internal rotation and abduction\/adduction, hand grip, and key pinch\/tip pinch. Average DASH and SF-36 scores were comparable with population norms. The PROMIS Upper Extremity score (46.2) was significantly lower than the average 50 (SD, 10.0); the Social Roles score (57.3) indicated significantly less disability than the general population. Seventy-nine percent reported higher than average satisfaction with life, 82% had normal self-esteem, and 21% and 4% met screening criteria for depression and anxiety, respectively. The Derriford Appearance Scale revealed that 68% of patients identified PS as their most self-conscious feature, with 36% reporting subsequent life adjustments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This cohort of PS patients self-reported more favorable functional, psychological, and emotional outcomes than expected based on significant shoulder and hand strength deficits.
