Abstract OBJECTIVE: To validate subgroups of cognitive impairment on the Montreal Cognitive Assessment (MoCA)-defined as normal (score of 25-30), mildly impaired (score of 20-24), and moderately impaired (score less than 19)-by determining whether they differ in rehabilitation gain during inpatient stroke rehabilitation. DESIGN: Observational study. Linear regression models were conducted and predictors included MoCA subgroups and relevant baseline demographic and clinical covariates. Separate models included the cognitive subscale of the FIM instrument as a predictor. SETTING: Inpatient rehabilitation facility of an urban, academic medical center. PARTICIPANTS: Inpatients (N=334) with mild-moderate strokes who were administered the MoCA on admission. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The mean relative functional gain (mRFG) and mean relative functional efficiency (mRFE, which adjusts for length of stay) on the FIM total. RESULTS: MoCA subgroups significantly predicted mRFG and mRFE after accounting for age, sex, education, stroke severity, and recurrent vs first stroke. The normal group exhibited greater mRFG and mRFE than the mildly impaired group, while the moderately impaired group had significantly worse mRFG and mRFE than the mildly impaired group. The moderately impaired group had a significantly smaller proportion of individuals who made a clinically meaningful change on the total-FIM than the mildly impaired and normal groups. MoCA subgroups better accounted for mRFG and mRFE than a standard-of-care cognitive assessment (cognitive-FIM). CONCLUSIONS: Use of MoCA-defined subgroups can assist providers in predicting functional gain in survivors of stroke being treated in inpatient rehabilitation.
