Idiopathic Edema
Conditions
Brief summary
The purpose of this study is to verify the efficacy and safety of the radiofrequency stimulation compared to the sham stimulation in reducing lower extremity edema in adult women with idiopathic edema.
Detailed description
In this study, based on the characteristics of radiofrequency, it was hypothesized that radiofrequency could have an effect on the reduction of lower extremity edema and prevention of fatigue. The occurrence of edema is interpreted as a problem that blood circulation is not smooth due to increased inflow of body fluid, and therefore the degree of edema is also used as an indicator of blood circulation. Therefore, in this study, based on the principle that radiofrequency promotes phosphorylation and blood circulation, the purpose of this study is to investigate whether radiofrequency treatment is effective in reducing edema of the lower extremities and changing body heat in the lower extremities compared to the gastric stimulation device through exploratory research.
Interventions
DEVICEradiofrequency
Radiofrequency of 9.50v, 218.5mA and 2.076W is applied once a day for 30 minutes, a total of 3 times
DEVICEsham stimulation
The appearance is the same as the medical device for clinical trials, and when applied, the sound and the amount of light visible from the outside are designed to be the same as the medical device for clinical trials. The external light was the same, and only the high frequency that stimulates the dermis was blocked. The sham device was applied once a day for 30 minutes, a total of 3 times.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Circumference(the lower calf at 7 cm proximal to the midpoint of the medial malleolus, behind the medial malleolus, and the dorsum of the foot) | Changes of circumference before and immediately after 30 minutes radiofrequency stimulation on once a day basis in the experimental group | Circumference was measured using a tape measure at three anatomical locations. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of Volume | Changes of volume before and immediately after 30 minutes radiofrequency stimulation on once a day basis in the experimental group | The leg volume test is measured using Volumeters (Deluxe Foot) of Jeongdo BNP Co., Ltd. in Korea. Measure using the principle of overflowing, fill a cylinder with a diameter of 30cm and a height of 30cm with water, put one leg in the cylinder with the ankle bent at 90 degrees, and take the overflowing water and measure the amount in ml. |
| digital infrared thermal imaging(DITI) | Changes of body heat before and immediately after 30 minutes radiofrequency stimulation on once a day basis in the experimental group | Measure the subject's leg body heat using DITI. |
| Visual analog scale(VAS) | Changes of VAS score before and immediately after 30 minutes radiofrequency stimulation on once a day basis in the experimental group | Discomfort VAS is used to measure the degree of discomfort for lower extremity edema after application of the device. And 0 indicates no discomfort at all, and 10 indicates the most severe discomfort imaginable. |
| weight | Changes of weight before and immediately after 30 minutes radiofrequency stimulation on once a day basis in the experimental group | Measure the participant's weight (kg) using a scale. |
