Figure 9From: A pilot study of sensory feedback by transcutaneous electrical nerve stimulation to improve manipulation deficit caused by severe sensory loss after strokeThe change of fluctuation index. The fluctuation index of the affected hand during the can grasp task assessed with SENS after training, plotted against days from the beginning of Experiment 1. The dashed line and gray zone are average and average plus/minus two standard deviations of fluctuation index of the unaffected hand, respectively.Back to article page
