The effect of the 2-week self-care using microcones on the range of motion in the cervical joint (A), shoulder joint (B), and shoulder girdle (C). Data obtained before (Pre) and after (Post) the self-care periods were compared using the paired t test or Wilcoxon matched-pairs signed rank test. Asterisks indicate a significant difference (*p < 0.05, **p < 0.01). Individual closed circles and lines indicate data obtained from each participant. The bar chart and vertical bar indicate the mean and standard deviation. A horizontal dashed line indicates a reference value of the range of motion (Japanese Society of Rehabilitation Medicine, 2021). N = 12 (except shoulder joint abduction, N = 11). Ext Rot = external rotation, Int Rot = internal rotation, Lat Flex = lateral flexion
