Establishing minimal clinically important differences and cut-off values for the lower limb motricity index and trunk control test in older patients with acute stroke: a prospective cohort study

Objective To establish the Minimal Clinically Important Differences (MCIDs) for lower limb strength measured by the Motricity Index (LLMI) and trunk function assessed by the Trunk Control Test (TCT) in the acute phase of stroke in older patients. Further, the study sought to determine the cutoff values predicting functional prognosis at discharge for both the LLMI and TCT.
