Using pulsed electromagnetic field therapy to reduce post-operative pain after orthopedic surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of pulsed electromagnetic field (PEMF) therapy in alleviating post-operative pain in patients undergoing shoulder or knee surgery. Participants will be assessed 10 days post-surgery using a visual analog scale (VAS) to measure pain levels, alongside tracking their daily pain medication intake and physical function outcomes. The intervention involves the use of the Endonovo SofPulse device, which delivers PEMF therapy to the affected areas. The study will include both male and female patients aged 18 and older who meet specific eligibility criteria.
