![]() ![]() ![]() Goal Attainment Scores were significantly and positively correlated with the total defect reduction ( p = 0.01), percentage increase reading speed was significantly and positively correlated with the defect reduction induced by training (epoch 1: p = 0.0044 epoch 2: p = 0.023). In subacute patients, training contributed about twice as much to their defect reduction as the spontaneous recovery. Defect reduction was significantly greater in the trained part of the defect than in the simultaneously untrained part of the defect irrespective of training onset ( p = 0.001). In both groups, field stability was assessed during a no-intervention period. The same paradigm was also applied to seven chronic patients for whom spontaneous recovery can be excluded and changes in the control half of the defect point to a spillover effect of training. Next, trained and control regions were swapped, and training continued for another 8 weeks. Spontaneous and training-induced recoveries were distinguished by training one-half of the defect for 8 weeks, while monitoring spontaneous recovery in the other (control) half of the defect. Visual discrimination training was started within 6 weeks after stroke in 17 patients. Here, we use a novel training design to dissociate these components for visual rehabilitation of subacute stroke patients with visual field defects such as hemianopia. Whether rehabilitation after stroke profits from an early start is difficult to establish as the contributions of spontaneous recovery and treatment are difficult to tease apart. ![]()
