Effects of Electrical Muscle Stimulation on Waist Circumference in Adults

Study Overview
=================
Brief Summary
-----------------
This randomized, placebo-controlled, double-blind, controlled study was designed to investigate the efficacy of electrical muscle simulation (EMS) for treatment of waist circumference (WC) reduction in abdominal obese adults. 60 patients with abdominal obese, man with WC > 90 cm and woman with WC > 80 cm, received EMS as experimental group (EG) or transcutaneous electrical nerve stimulation (TENS) as control group (CG) 5 times a week for 12 weeks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Electrical Muscle Stimulation<br>Electrical Muscle Stimulation (EMS) program was consisted of warm-up, warm-down, contraction and relaxation. It was programed to be resemble to actual muscle action of voluntary exercise. To increase energy consumption as high intensity exercise, tripled the contraction duration. EMS group used Program 3 and regulated intensity though channel from 1 to 4. | Device: Electrical Muscle Stimulation<br>* Participants were under EMS 5 times a week for 12 weeks. Pads were applied on participants' abdomen, rectus abdominis and external oblique abdominal muscle areas without any recent wound, infection, scar, and warts while lie on their back.<br>|
| Placebo Comparator: Transcutaneous Electrical Nerve Stimulation<br>Transcutaneous group used Transcutaneous Electrical Nerve Stimulation (TENS) which is the use of electric current produced to stimulate the sensory nerves to block pain signal. It is programed to applied currents regularly, once a second with a frequency of 1 Hz. | Device: Transcutaneous Electrical Nerve Stimulation<br>* Participants were under TENS 5 times a week for 12 weeks. Pads were applied on participants' abdomen, rectus abdominis and external oblique abdominal muscle areas without any recent wound, infection, scar, and warts while lie on their back.<br>|
