Abstract: The study purpose was to assess 6 shoulder patient-reported outcome measure (PROM) values in asymptomatic, healthy, pathology-free in iduals. We hypothesized that there would be no difference in PROM values in pathology-free in iduals when considering sex, age, ethnicity, and geographical location. Electronic questionnaires were completed by 635 in iduals (323 Australians and 312 Canadians) without dominant shoulder pathology for the American Shoulder and Elbow Surgeons (ASES) shoulder score Constant-Murley Shoulder Score (CSS) Oxford Shoulder Score (OSS) University of California, Los Angeles (UCLA) shoulder score Shoulder Pain and Disability Index (SPADI) and Stanmore Percentage of Normal Shoulder Assessment (SPONSA). Shoulder range of motion and strength were assessed. No difference was identified between subjective-only and subjective-objective PROMs. Handedness and a current elbow or wrist problem were not associated with differences in PROM values. Poorer PROM values were associated with a history of an inactive shoulder problem and increasing age. Female participants tended to report similar or poorer PROM scores. No significant difference was found between ethnicities. Geographical location was associated with differences in the ASES shoulder score, UCLA shoulder score, and SPADI but not the CSS, SPONSA, and OSS. Differences in sex, age, and geographical location will affect PROM shoulder scores in pathology-free in iduals and should be taken into consideration when PROMs are being used to compare patient outcomes. This study has established normative values for the ASES shoulder score, CSS, OSS, UCLA shoulder score, SPADI, and SPONSA. Future studies assessing a pathologic patient cohort should perform comparisons against a sex- and age-matched control cohort, ideally sourced from the same geographical location.
