Background: Although self-limiting, delayed-onset muscle soreness (DOMS) declines performance of the athletes. The aim of the present study was to compare the effects of repeated use of cryotherapy and transcutaneous electrical nerve stimulation (TENS) on signs and symptoms following hamstring DOMS. Methods: This study used a randomized controlled trial design. Thirty-two participants were randomly allocated into a TENS or cryotherapy group. Ten participants were also considered as a control group. Pain, active knee extension range of motion (AROM), triple-hop distance and thigh girth were assessed before, 24, 48 and 72 hours after inducing DOMS in the dominant hamstrings muscle. Results: Two-factor repeated measures analysis of variance showed a significant main effect of time for pain intensity, AROM and triple hop distance(P<0.05), and main effect of group for pain intensity and AROM(P<0.05), and interaction effects of group×time for pain intensity and AROM(P<0.05). Post hoc statistical tests showed that mean of pain intensity and AROM was changed by cryotherapy group(P<0.017). Conclusion: Presence of pain, decreasing AROM and reducing triple hop distance confirmed the induction of DOMS in the hamstrings. Cryotherapy was more effective than TENS for controlling pain and improving AROM after DOMS. Triple hop distance, as a measure of function, was not able to detect dominance of cryotherapy or TENS for controlling DOMS of the hamstrings in spite of repeated use of these interventions.

In this article, the reasons for the occurrence of Delayed Onset Muscle Soreness (DOMS) and the effect of electrotherapy on it were discussed. Electrotherapy is a non-invasive and easy method to treat DOMS and muscle fatigue. As a result of intense and abnormal exercise, the creatine phosphokinase enzyme in the muscle increases and DOMS occur. DOMS can be treated with electrotherapy techniques such as micro-current electrotherapy. Micro-currents devices reduce the severity of DOMS symptoms by maintaining intracellular calcium homeostasis. Devices such as Transcutaneous Electrical Nerve Stimulation (TENS) and Micro-Current Electrical Therapy (MET) belong to the category of micro-currents. The number of electrotherapy sessions after the occurrence of DOMS and the frequency of electrotherapy devices are two important factors in the treatment of DOMS. TENS conducts electrical current to the body through electrodes that attach to the skin, and helping to reduce pain by releasing endorphins, a natural painkiller, and blocking the passage of pain to the brain. MET uses resonant frequencies to aid in deeper and longer treatment, increase the body’s production of natural catalysts in the healing process, and is more useful in chronic pain than TENS. Research has shown that electrotherapy has been shown to improve DOMS symptoms.

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.
