The primary outcome measure was the vertical displacement of the humeral head\u2019s center of rotation before and after treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>From January 15, 2023 to January 3, 2024, 63 patients with rotator cuff tears were randomly assigned to either the experimental (n\u2005=\u200532) or control (n\u2005=\u200531) group. Additionally, 49 healthy volunteers were included as a healthy control group. All participants underwent X-ray imaging of shoulder abduction at 0\u00b0 and 30\u00b0 before and after the treatment. The experimental group received a 3-month regimen of conservative management combined with MTT targeting the scapulothoracic muscles, whereas the control group received only conservative treatment. An image-based measurement technique quantified the relative upward migration of the humeral head.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Before treatment, the relative upward migration was similar between the experimental (7.06%) and control groups (7.30%,\n                      <jats:italic toggle=\"yes\">P\u2005<\/jats:italic>\n                      =\u2005.57). After treatment, the experimental group exhibited a significant reduction in upward migration (4.93%) compared with that in the control group (7.02%,\n                      <jats:italic toggle=\"yes\">P\u2005<\/jats:italic>\n                      &lt;\u2005.001). By contrast, the control group displayed only a minimal decrease from 7.30% to 7.02%.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>MTT significantly reduces the upward migration of the humeral head during shoulder abduction, leading to improved rehabilitation outcomes, whereas conventional conservative treatment has minimal effect on migration reduction. By enhancing shoulder joint stability and potentially slowing the progression of rotator cuff degeneration, MTT represents a valuable adjunct to conservative management strategies.<\/jats:p>\n
