The rate of recovery from stroke - and its measurement

A battery of tests to measure improvement over time in physical recovery of stroke patients - and to compare this with varying levels of disability at onset, is described. Recovery in a series of 135 patients with fresh stroke treated by traditional methods of rehabilitation is principally in the first 3 months - but also continues in the second 3 months, except for muscle power. Recovery after 6 months is least in muscle power and is limited mainly to walking and mobility (e.g. getting out of the house) which in some cases may be due to altered environmental factors. At onset only 62 per cent showed moderate or severe impairment of muscle power compared to 88 per cent with similar impairment in mobility and dependency. By 1 year 30 per cent of survivors remained dependent.
