RT Journal Article SR Electronic T1 Functional abilities after stroke: measurement, natural history and prognosis. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 177 OP 182 DO 10.1136/jnnp.50.2.177 VO 50 IS 2 A1 D T Wade A1 R L Hewer YR 1987 UL http://jnnp.bmj.com/content/50/2/177.abstract AB Actual functional performance of 976 acute stroke patients was assessed using the Barthel index: the data were analysed to determine the frequency of disability after stroke, the validity of the Barthel index, and the recovery seen. At 6 months, over 45% of survivors were functionally independent. Validity of the Barthel index was confirmed: it related as expected with motor loss and factor analysis showed a single major factor. The items of the Barthel index form an hierarchical scale. There was some recovery between 3 weeks and 6 months in almost all patients: the major prognostic factors were urinary incontinence, functional ability, sitting balance and age.
