The primary outcome was ultrasound-assessed repair integrity at 6 months after repair. Recruited patients were randomized into 2 groups: one group received a vibration device that oscillated at 80 Hz, and the other group received a placebo device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The postoperative retear rates of both groups were similar (9.1% [5\/55] in the vibration group, and 9.3% [5\/54] in the placebo group) at 6 months as determined by ultrasound imaging. Vibration did provide acute pain relief at 6 weeks after surgery (visual analog scale [VAS] score, 2.24 \u00b1 0.29 cm) compared with placebo (VAS score, 3.67 \u00b1 0.48 cm) ( P &lt; .003). Six months after surgery, both groups had significant reductions in pain during overhead activities, at rest, and during sleep and overall shoulder pain compared with before surgery ( P &lt; .001). Both the vibration and placebo groups had significant increases in shoulder strength with abduction in the scapular plane, adduction, liftoff, internal rotation, and external rotation 6 months after surgery. Statistical analysis showed that vibration was not a contributing factor at improving these parameters in these periods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>High-frequency, low-magnitude vibration did provide acute pain relief on application 6 weeks after arthroscopic rotator cuff repair surgery.
