Official title

A Pilot Prospective, Randomized, Placebo-Controlled Study to Evaluate the Efficacy of Pulsed Electromagnetic Field (PEMF) Therapy in Decreasing Post-Operative Pain Following Orthopedic Surgery

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary objective of this study is to prospectively determine, at 10 days after orthopedic shoulder or knee surgery, if pulsed electromagnetic field (PEMF) therapy is beneficial in reducing patient-reported post-operative pain, as measured by visual analog scale (VAS). The amount of pain medication taken daily and the physical function outcome scores after surgery and PEMF treatment will also be measured.
