Background. Therapeutic ultrasound (US) is an electrophysical therapy that is commonly used by sports physiotherapists, but its mechanismof action is unclear. There is little evidence that US therapy is more effective than sham US therapy, and any clinical benefits may be dueto a placebo effect.Objective. To investigate whether US has a specific effect that renders it effective in its own right, or whether its effect is placebo driven.Methods. In a double-blind controlled trial, delayed-onset muscle soreness (DOMS) was experimentally induced in both bicep musclesof 15 females. Sham US was applied to one bicep (n=15 biceps) and pulsed active US to the other bicep (n=15 biceps) of each participant,48 and 72 h after induction of DOMS. Primary and secondary outcomes were pain reported on the McGill Pain Questionnaire (MPQ) andrange of movement (ROM) (elbow extension) measured by goniometry, respectively.Results. Results showed significant improvements in pain and ROM over the intervention periods, but there was no difference betweeninterventions.Conclusion. US and sham US therapy improve pain equally when treating DOMS of the biceps in the context of a therapeutic encounter.This analgesic effect is placebo driven. Clinicians can influence the analgesic effect of US by managing the therapeutic context. Managementof patients’ anxiety may also boost the analgesic effect of US.
