Mean change scores in impairment level measures by perceived change ratings and upper extremity affected. Error bars represent standard errors. A: Grip strength in the affected hand, measured in kgs as part of the Wolf Motor Function Test. B: Composite upper extremity strength on the affected side; values are expressed as ratios of the unaffected upper extremity. Perceived change ratings: 1 = Much better; 2 = A little better, meaningful; 3 = A little better, not meaningful; 4 = About the same.
