Injuries hinder athletic performance. Athletic trainers must use every tool at their disposal to expedite recovery time from injury. Electrotherapy is one of the most common therapeutic modalities utilized. The purpose of this study was to examine standard Microcurrent Electrical Nerve Stimulation (MENS) protocol versus InterX with the Flexible Array attachment on the reduction of pain associated with delayed onset muscle soreness (DOMS). DOMS was initiated using eccentric bicep curls. Subjects completed a pain scale after exercise and then were randomly assigned to one of three treatments: InterX, MENS, or no treatment. Each subject was to complete the exercise bout and then receive one treatment. In six or seven days they would repeat this procedure until they received each of the three treatments. The subjects also filled out a pain scale 24 hours after respective treatment.
The results found no statistical significance among the three treatments regarding reduction in pain scores. However InterX did reveal the greatest decline of pain scores compared to MENS and no treatment. A larger sample size may reveal a statistical significance between InterX and MENS on DOMS symptoms reduction.
