title: Temporal recovery of activities of daily living in the first year after ischemic stroke: a prospective study of patients admitted to a rehabilitation unit.
abstract: BACKGROUND
  The ability to perform basic activities of daily living (ADL) independently is a marker of functional recovery after a stroke. However, there few studies documenting their long-term recovery.
  
  
  OBJECTIVE
  To document temporal recovery of activities of daily living (ADL) and establish predictors of ADL in a cohort of ischemic stroke patients in the first year after stroke.
  
  
  METHODS
  Prospective cohort study of 163 patients with first-ever ischemic stroke admitted to a rehabilitation centre. The Modified Barthel Index (MBI) was used to measure the patient's ability to perform the following 10 ADLs: feeding, grooming, dressing, bathing, toileting, bladder and bowel continence, transfers, ambulation and stair climbing. It was assessed on rehabilitation admission, discharge, and at 3, 6 and 12 months after stroke. The Motricity Index was used to measure motor power of the hemiplegic limb.
  
  
  RESULTS
  The mean age was 63.8 (10.7) years, with 111 males and 52 females. The mean total MBI scores on rehabilitation admission, rehabilitation discharge, 3, 6 and 12 months after stroke were 41.3 (24.6), 72.9 (20.5), 88.4 (18.6), 90.5 (17.2) and 84.2 (20.4) respectively. Median scores of feeding, grooming, toileting, bladder/bowel continence, transfers and ambulation plateaued by 3 months after stroke. Median scores of dressing and stair climbing plateaued at 6 months and that for bathing, 12 months after stroke. None of the patients were functionally independent (defined as MBI score of 100) on rehabilitation admission, but this improved to 8.6% on discharge, and 32.1%, 41.4% and 50.3% at 3, 6 and 12 months after stroke respectively. The MBI and Motricity scores were strongly correlated at all periods of follow up (r = 0.67 to 0.69, p < 0.0001). Univariate analysis showed that age, neglect, a cortical stroke, admission MBI, NIHSS, Motricity Index and Abbreviated Mental Score scores were predictors of functional independence at 12 months after stroke. On logistic regression, only age remained significant, younger patients being more likely than older patients to be functionally independent.
  
  
  CONCLUSIONS
  Most recovery of ADL occurs by 3 months after stroke. For individual ADLs, dressing, stair climbing and bathing appear to take a longer time to recover. Older age was a negative predictor of functional dependence at 12 months after stroke.
