However, descriptive responsiveness patterns across spasticity severity levels remain insufficiently explored. This study aimed to descriptively examine functional changes and responsiveness across ankle plantar flexor spasticity severity categories in individuals with subacute stroke.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      In this prospective observational cohort study with a 4\u2010week follow\u2010up, 58 participants were categorized based on ankle plantar flexor spasticity severity using Modified Ashworth Scale (MAS) scores (MAS\u00a0=\u00a00, MAS\u00a0=\u00a01\u20131\n                      <jats:sup>+<\/jats:sup>\n                      , and MAS\u00a0\u2265\u00a02). Functional performance was assessed using the 10\u2010M Walk Test (10\u00a0mWT), 6\u2010Minute Walk Test (6\u00a0MWT), Timed Up and Go (TUG), 5\u2010Times Sit\u2010to\u2010Stand Test (5\u2010Times STS), Figure\u2010of\u20108 Walk Test (F8WT), and Four Square Step Test (FSST) at baseline and after 4\u00a0weeks. Responsiveness was quantified using effect size (ES) and standardized response mean (SRM), and subgroup findings were descriptively examined across MAS categories.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All outcome measures showed changes over 4\u00a0weeks, with moderate\u2010to\u2010large responsiveness observed across tests. Responsiveness estimates appeared numerically greater in the MAS\u00a0=\u00a00 subgroup, whereas more variable estimates were observed in participants with spasticity (MAS\u00a0\u2265\u00a01). Similar patterns were observed across gait\u2010related and functional mobility measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Responsiveness estimates varied across spasticity levels, suggesting that responsiveness, as a measurement property, may differ according to impairment severity. These findings provide preliminary descriptive information regarding responsiveness across spasticity severity categories.
