PEMF Effects on Pain After Abdominal Body Contouring

Study Overview
=================
Brief Summary
-----------------
Body contouring surgery has a higher potential for postoperative pain and wound healing complications. The purpose of this study is to determine if pulsed electromagnetic field (PEMF) devices can reduce the pain and complications associated with this type of surgery. Pulsed electromagnetic field (PEMF) devices have been shown to be effective treatments to decrease healing time in nonunion fractures and pressure ulcers, and to reduce pain in whiplash injuries, persistent neck pain, and chronic lower back pain. These devices have been FDA approved for treatment of pain and edema (510(k) number: K070541). More recently, PEMF devices have been shown to decrease postoperative pain and narcotic use in breast augmentation patients. This study seeks to determine if PEMF will also cause similar effects in the more complex procedures performed on body contouring patients. The specific aims of this study are: Evaluate if adjunct PEMF therapy will accelerate the rate of postoperative pain reduction in abdominal body contouring patients. Evaluate if adjunct PEMF therapy will decrease the postoperative use of narcotic pain relievers in abdominal body contouring patients. PEMF devices have been shown to be effective in reduction of pain and pain medication use in breast augmentation patients. No literature has shown if PEMF is an effective adjunct to decrease pain or pain medication use in the abdominal body contouring patient. A decrease in pain would result in a better experience for patients and a reduction in pain medication may decrease complications associated with these medications. The PEMF therapy device being used in this study is a non-significant risk device because it is noninvasive and does not present a potential for serious risk to the health, safety, or welfare of a subject.

Inclusion Criteria: Age: 18 years and older and able to provide informed consent Eligible for and have agreed to be scheduled for elective abdominal body contouring surgery Willing and able to comply with all study procedures. Exclusion Criteria: Inability to provide informed consent Patients having multiple procedures concurrently except liposuction.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Active Device<br>Device Placement: Upon completion of the subjects' standard of care body contouring surgery, the device will be placed directly on the operative dressings within an unobtrusive binder with Velcro strips and will be activated before the subject leaves the OR. Subjects will then be educated on the functionality and interpretation of the user interface of the device. They will be educated on the application, removal, and return of the device. Active Devices The device will be activated at the time of placement. The active devices are programmed to automatically deliver treatment. Each treatment duration is 15 minutes. The active device delivers treatment every 2 hours. A light will flash on the device when the PEMF begins and will continue to flash every second until the end of the treatment. Between treatments the device will be in sleep mode and the light will flash every 5 seconds. | Device: Active Device (IVIVI SofPulse)<br> <br> * Other names: IVIVI SofPulse;|
| Sham Comparator: Sham Device<br>Device Placement: Upon completion of the subjects' standard of care body contouring surgery, the device will be placed directly on the operative dressings within an unobtrusive binder with velcro strips and will be activated before the subject leaves the OR. Subjects will then be educated on the functionality and interpretation of the user interface of the device. They will be educated on the application, removal, and return of the device. Sham Devices The sham devices mirror the active device with the exception of the delivery of the PEMF. The sham device will be activated at the time of placement. A light will flash on the device when the SHAM PEMF begins and will continue to flash every second until the end each treatment interval. While in sleep mode the device will not deliver treatment and the light will flash every 5 seconds. | Device: Sham Device<br> <br> |
