About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Women between the ages of 19 and 72
  • Those who are not likely to menstruate during the trial treatment period (3 days) (females within 8 to 18 days after the onset of menstruation)
  • Those who meet the diagnostic criteria for idiopathic edema (McKendry criteria score of 15 or higher)
  • Those who show a weight change of 1.4 kg or more between morning and night measurements
  • Those who have a difference of 1cm or more from the ankle or 2cm or more from the calf when measuring the circumference in the morning and evening
  • Those who voluntarily agree to participate in this clinical trial and sign the consent form

Exclusion criteria

  • In the case of using a heart rate control device such as a metallic substance in the human body
  • During menstruation or if there is a possibility of pregnancy
  • If you have heart disease
  • If you have liver or kidney disease
  • If there is bleeding or internal bleeding from wounds or surgery
  • For hypertensive patients
  • For epilepsy patients
  • If you are taking weight loss or health-related drugs/health functional foods
  • In the case where it is judged by the principal investigator that participation in this study is not appropriate

Treatment and study plan

Radiofrequency

Device

Radiofrequency of 9.50v, 218.5mA and 2.076W is applied once a day for 30 minutes, a total of 3 times

Other names: high frequency

Sham stimulation

Device

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.

Primary outcomes

  1. 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)

    Time frame: 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 outcomes

  1. Change of Volume

    Time frame: 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.

  2. digital infrared thermal imaging(DITI)

    Time frame: 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.

  3. Visual analog scale(VAS)

    Time frame: 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.

  4. weight

    Time frame: 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.
