Next, he quantified their active range of shoulder rotation with a goniometer, and the strength of their shoulder rotators and deltoid muscles in position suggested by the Kendall's manual muscle testing procedures.
It may be concluded that restriction of shoulder rotation ROM is present in patients with lateral epicondylalgia, probably due to a facilitated level of shoulder rotator muscle tone.
By what magic can she make a shoulder rotation seem significant?
*Test for shoulder rotation by having the child place one arm and then the other behind the back.
Usually no shoulder rotation is possible, but the mechanical elbow and terminal device function as in other arm prostheses.
Shoulder rotation accompanies elevation movements in day-to-day activities.
Passive sliding follows changes in the center of shoulder rotation.
The main methodological difference from previous studies (Bey et al. 2008; Kozono et al. 2017) was that shoulder rotation in this study was repetitive shoulder rotation.
X-axis represents shoulder rotation (Full IR: Full internal rotation; Full ER: Full external rotation).
This rotation cycle was used to normalize the slackened capsuloligamentous area in shoulder rotation range.
Consider how the humeral head is subjected to accelerations, decelerations and changes direction of shoulder rotation.
