Intensity of rehabilitation: In 2006, a meta-analysis of 21 studies on the effect of muscle strengthening post stroke showed that it improved active function and activities of daily living (measured on different scales) following acute and chronic stroke (Ada et al, 2006). Currently, a meta-analysis by Brazzelli et al. (2011) contains the largest collection of data, with 32 studies and a total of 1414 participants. The studies included were on the subject of cardiovascular training, muscle strengthening and mixed training (cardiovascular+strength). The main outcome measures were the incidence of mortality and the degree of dependence and disability. The results showed improvements following cardiovascular training and mixed training. Strength training alone did not significantly improve mobility. These results lead the American College of Sport and Medicine to recommend endurance and strength training coupled with stretching for stroke patients.
