Supraspinatus tendonitis (SST) is a common source of shoulder pain that primary care, sports medicine, and orthopedic surgeons regularly manage. TrueRelief's FDA-cleared device, called TrueRelief 1250, is a noninvasive technology that provides pain relief through the delivery of high frequency pulsed direct electrical current to the skin surface around the location of the tendonitis via anode and cathode probes. This study will assess if TrueRelief may be an effective option in treating SST, given the preliminary data surrounding its anti-inflammatory and subsequent analgesic properties. The investigators are proposing the first double-blind, randomized, sham-controlled study of TrueRelief to determine a more accurate measurement of its efficacy, specifically in patients with SST. The investigators hypothesize that TrueRelief will result in improved outcomes in this patient population compared to those receiving the sham TrueRelief treatment.
The investigators hypothesize that TrueRelief will result in improved outcomes for patients with shoulder pain compared to those receiving the sham TrueRelief treatment. Also, it is likely that those with fewer medical comorbidities will experience the greatest improvement.
