ICF-RS scores (30 categories) were assessed at admission and discharge. Responsiveness was evaluated using Wilcoxon signed-rank tests with Benjamini-Hochberg FDR correction. Response counts (improved\/stable\/worsened) were the primary outcome presentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 30 ICF-RS categories, 27 showed 100% data completeness; 3 social\/sexual items had substantial missingness. Following rehabilitation, 23 categories demonstrated statistically significant improvement after FDR correction. Consistent directional improvement was observed in mobility (d450 Walking: 24\/47 improved), self-care (d510\u2013d540), and pain (b280: 26\/47 improved) domains. The total score decreased from 47.51\u2009\u00b1\u200913.59 to 35.81\u2009\u00b1\u200911.38 (Cohen's d\u2009=\u20091.51). Notably, b710 (joint mobility) showed no responsiveness (0\/47 improved, 1\/47 worsened), despite expected clinical range-of-motion gains.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>ICF-RS demonstrates responsiveness to post-TKA inpatient rehabilitation for most functional domains. The lack of change in b710 highlights a limitation of generic assessment tools for capturing localized physical impairments in single-joint conditions, suggesting the need for complementary condition-specific measures. The study context\u2014where ICF-RS scores influence reimbursement\u2014underscores the importance of assessment integrity considerations in function-based payment implementations.<\/jats:p>\n
