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
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.

• Subject must not have used NSAIDs for one (1) week prior to surgery.
• a. a. Low-dose aspirin (81 mg) is permitted.
• Subject must be willing and able to participate in post-operative physical therapy exercises.
• Subject must understand and be willing to sign the IRB-approved Informed Consent Document.
