Koryo Hand Therapy (KHT) is called Koryo Sooji Chim, Korean Hand Acupuncture or Soojichim. KHT (Koryo Hand Therapy) theorizes that the hands are a micro-cosmos of the body. The function of the human body can be manipulated by stimulating the corresponding points on our hands.� According to the theory of 'Koryo Hand Therapy', there are 14 micro-meridians and 345 acupuncture points on our hands, which regulate the internal organs of human body. These acupuncture points may be stimulated by using the following instruments: Hand Needles, Seoam Press-Pellets, Seaom Moxa, E-beam, Magnets, KHT Silver Ring, or Cyber Hand Therapy.� Thus stimulating these acupuncture points on the hands can regulate the physiological function of the entire body.

The theory of Koryo Hand Therapy was first originated, studied and developed by The Korean acupuncturist, Dr. Tae Woo Yoo between 1971 and 1975. Since that time Koryo Hand Therapy has spread to the public worldwide.� Koryo Hand Therapy is a scientific medical system that is quite simple to learn and easy to perform without any side effects or danger to the patient.

If you are in pain or have a problem somewhere in your body, the reactions are reflected on the hands in the form of tender points. Pain commonly or frequently shown on the hands corresponds to the painful part of your body. Therefore, the stimulation of the tender points positively affects pain relief.

Koryo Sooji Chim is very effective in treating a wide range of ailments such as infertility, rheumatic arthritis, allergy and stroke, but there are limits to what it can accomplish. Clearly, conditions that require surgery and infectious diseases cannot be cured using hand acupuncture. However, KHT treatment can play a useful part in complementing Western Medicine by alleviating pain and promoting recovery and lessen the side effects of chemotherapy in cancer patients, relieving nausea, so that the patients can continue to receive the treatment.

KHT contributes to the maintenance of a person's health as well as self-diagnosis. It is possible to perform self-treatment, treat family members and even employ KHT as a volunteer activity (for charity for example).

Prior to discovering Koryo Hand Therapy, traditional acupuncture that utilizes the whole body for treatment was the subject of Dr. Yoo's research and practice. However, in his practice of traditional acupuncture, he noticed some disadvantages or shortcomings in body acupuncture needles. The needles were thick and long; thus the insertion was deep and painful. These thick and long needles may cause serious side effects such as deafness, paralysis, and unconsciousness as well as aggravation of disease.

Dr. Yoo sometimes observed that the ailments were not healed well when treatment was performed according to meridian theories of traditional body acupuncture. As he studied body acupuncture more deeply, he took a skeptical and negative view of meridian theories in Traditional Body Acupuncture since the presence of the meridian could not be proven in a scientific experiment.� In addition, it was difficult for lay people to understand traditional body acupuncture since the theories were too abstract and idealogic.� Dr. Yoo started to study a new concept of acupuncture that is quite simple to learn and safe to perform without any side effect.

His interest in physiognomy urged him to study the relationship of the face and body more profoundly and he came to realize that the face is interrelated to the diseased part of the body. In other words, the entire body is represented on the face. The condition of the body can be foreseen by looking over the face. For instance, if you have a clean and smooth forehead without any wrinkle, it means that the body is healthy and the function of the stomach is good, however, if you have many wrinkles and a rough forehead, it indicates that the body has constant slight ailments, especially some problems related to the function of the stomach.

Finally, Dr. Yoo got a hint that the entire body is represented on the hands as the entire body is on the face.� In addition, Dr. Yoo studied the theory of the visceral-somatic reflex that is based on the following hypothesis; reaction and changes occur on their corresponding or interconnected organs, tissues, muscles and skin through the nervous system when certain viscera are infected and / or disordered.� For example, when there is any abnormal change in the viscera, the nerve impulse is transferred to the central nervous system by the afferent nerve fibers of the autonomic nerves. Once it reaches the brain, the brain commands the affected body parts through the efferent nerve fibers. The mechanism of correspondence in Koryo Hand Acupuncture is very similar to the mechanism of the visceral-somatic reflex.

The stimulation of the corresponding points of certain body parts initiates the hand to organ reflex first then the organ-to-organ reflex. A large number of different human diseases can be treated or cured through the route of the reflex system, and this theory has been verified by clinical experiments such as thermograms.� The stimulation of the hand is very effective due to the presence of a large number of sympathetic nerve fibers in the hands.
