Unilateral wrist extension and ankle dorsiflexion training produce amplified increases in strength after stroke. Compared with neurologically intact, chronic stroke participants show larger strength gains on both trained (less affected) and untrained (more affected) sides. Percentages of the strength gain in chronic stroke participants are obtained from the studies of Dragert and Zehr (9) and Sun et al. (10). Data from neurologically intact participants are from the meta-analysis by Green and Gabriel (26).
