120 patients diagnosed with a rotator cuff tear undergoing arthroscopic rotator cuff repair were randomly assigned to receive a high-frequency, low-magnitude vibration treatment or a placebo treatment for 6 months following surgery. The purpose of this study was to investigate the effect of high-frequency, low-magnitude vibration on retear rate and to determine if this treatment provides any additional benefits over placebo treatment in terms of shoulder strength, range of motion or pain severity/frequency following surgery. No significant differences in retear rates were observed between groups at 6 months, and the application of high-frequency, low-magnitude vibration was found to provide no additional benefits over placebo treatment in terms of VAS pain scores, frequency of pain, severity of pain, shoulder strength, range of motion, or patient satisfaction, as patients in both groups demonstrated similar improvement in all parameters. It was noted that the application of vibration at 6 weeks had a significant effect on acute pain.
