What is the ElesAs?

The made in Japan "ElesAs" is a portable microcurrent therapy unit to recover one’s motor function.

Unlike the other electrotherapy unit which uses a strong electricity and establishes the “gate control theory”,

ElesAs uses microcurrent to relieve pain and swelling caused by injury to muscles, ligaments and tendons in sports.

The Spec of ElesAs.

By realizing energy saving, the maximum power consumption is about one-fifth that of a typical desktop computer. Loaded a nickel metal hydride battery, it can be used for up to 10 hours on a single charge. Designed for ease of use and easy to operate. Realizing weight reduction and slimming, the weight is "4.4kg" which is about half of the conventional treatment device. As it can be used anywhere, it is ideal for therapist's home visit, and on-site athlete care.

How does it work?

Damage to cell membranes or abnormalities in membrane potential, by injuries or overwork or stress etc., increases the internal impedance and reduces the tissue conductance. These results in the disruption of the body’s normal electrical balance. As shown on the right picture, to treat this disruption, ElesAs occurs a two-way communication.

This communication enables ElesAs to confirm the impedance value of the area treated by its own computer circuitry, and to the body it will introduce the needed gentle current, in waveforms. This communication is repeated until the impedance gets near the normal value.

  1. feedback current output
  2. Input the internal impedance of the body
  3. Waveform adjustment and output for input information
  4. Input changed internal impedance

Repeat step  3-4  many times

The first set frequency and pulse value should be changed due to the result of the communication. The result, or by means the change of the impedance is shown by the feedback value; the higher the feedback the better the normalizing of the impedance. After the impedance is normalized, ElesAs will help to keep the normalized impedance value.

Electrical properties in biological tissue

The basic unit of biological tissue is a “cell”. The basic function of the cell is to produce electron energy or potential energy. For example, the function “Substance metabolism” is that. Substance metabolism is constituted by catabolism (an action that decomposes complex compounds taken from the outside into simpler substances (potential energy), and electron energy is released when decomposed.) and anabolism (an action that reforms materials taken from outside into chemical structures (potential energy) necessary for daily life). So, as described, electron energy and potential energy are produced by these actions.


Therefore, cells can be simply expressed as an electrolyte containing various quasi-cell structures necessary for substance metabolism, cell repair and reproductive action. When the quasi-cell structure is in the resting state, it is completely enveloped by cell membrane with low current leakage.


According to a biophysicist’s report, the cell membrane capacitance (capacitance of a conductor whose potential increases by 1 V) is 0.1 to 3.0 μF/㎠, but the resistance value range of cytoplasm is 10 to 30,000 Ω/cm((300-400Ω), which is typical for mammals.


In general, group of cells enclosed by, or bond to extracellular matrix containing electrolyte solution is called a biological tissue.


Therefore, when considering the electrical characteristics in the biological tissue, in the case of mode 1, since the capacitive reactance of the cell itself is small, the current flows through the protoplasm, as well as the surrounding tissue fluid. On the other hand, it is important to pay attention to the fact that in mode 2, the current which passed through the organs, that are biological tissues, affects the cell through the surrounding environment

Mode 1 creates electrical potential difference that controls the calcium permeation of muscle fiber membranes, resulting in the increase of intracellular calcium levels, and or causing protein synthesis and processes related to cell repair.

The change in polarity repeated every 2 seconds creates the potential difference that allows the permeation of ions.

As shown below, when the cells and the external environment of the body are adjusted, resulting in the homeostasis be reconstructed, the healing speed is improved by 30% or more compared to the conservative therapy. As a result, the pain is immediately reduced or eliminated.

【Note】Physical electrotherapy equipment 

A typical electrotherapy device uses mA current to suppress pain transmission and stimulate muscle movement. The pain transmission is suppressed by changing the excited pain gate to inhibitory, with stimulating the gate by electrical stimulation to the nerve in the affected or nearby area faster than the pain signal. (This is the called “Gate Control Theory”) Muscle movement stimulation increases the amount of current. The blood flow increases when muscle pumping and re-education are performed by contracting the muscle passively by electrical stimulation. The repair speed of tissues involved in healing varies depending on the age and activity level.
