The magnitude of changes in subjective symptoms (A) and range of motion (B–D). Data obtained before self-care periods were subtracted from those after self-care. The individual closed circle indicates data obtained from each participant. The bar chart and vertical bar indicate the mean and standard deviation. N = 12. Ext Rot = external rotation, Int Rot = internal rotation, Lat Flex = lateral flexion, ROM = range of motion, VAS = visual analog scale
