In the above article, a sentence in the Methods section, paragraph 2 (page 2) should be revised as follows:
Current text: The inverted-W position was defined as the elevation of 1 or both elbows above shoulder level in the early cocking phase of the throwing motion (Figure 1).
Corrected: The inverted-W position was defined as the elevation of both elbows above shoulder level combined with internal rotation in the early cocking phase of the throwing motion (Figure 1).
In addition, the image in Figure 1 (page 2) should be replaced by the image shown below.
