Lateral pinch strength improved in both the right and left hands during stimulation combined with physical therapy. During four weeks of stimulation combined with physical therapy, pinch strength improved 2-to 7-fold in the presence of stimulation for the left and right hand, respectively. Physical therapy alone (PT only) resulted in no further improvement, but all gains were maintained during three months of follow-up. Each data point is the average of three maximal contractions performed on a given day, and error bars are standard deviation.
