By sudden relaxation techniques external tension patterns are reduced and shifted towards the inside of the body.


Sotaiho is a modern body therapeutic system developed by the Japanese physician Dr. Keizo Hashimoto. Main point is the idea that the body could be restored by emphasizing the pleasant movement.
Sotaiho is also a manual-medical method that Dr. Hashimoto developed from traditional oriental healing arts. Untwisting muscular holding patterns, it is a method of neuro-muscular restructuring in the body.

When Dr. Hashimoto began with his practical activity as a physician, he had to find out that the learned methods partly brought unsatisfying results, especially in case of shoulder- / neckpain and loins complaints.

One day he noted with some patients an improvement, after they were in treatment with an acupuncturist or a manual therapist. So he began to examine each of his patients on their build: He recognized that the method of the backward motion treatment, discovered by Michio Takahashi in the 1920s, achieved good results.

The construction of the body
Dr. Hashimoto recognized that the organism always moves as a unity and formulated from it “the law of reciprocity” (“Doji-sokan-sohosei”).

The construction of the human body resembles in principle that of a house. Four supporting piers correspond to our arms and legs, the ridge corresponds to the spinal column.
If the balance one of these pillars is disturbed sensitively, this will become apparent as a malfunction in the backbone.

There are hardly people by whom the mobility of the spinal column would not be slightly limited. Malfunctions in the spinal column find their origin mainly in a lateral imbalance.

This has to do with the fact that we appropriate movement habits since earliest infancy which will be finally pulled, through the whole life. On the other hand tense organs can cause by reflex an imbalance in the trunk musculature as well.

The following regularity can be derived from here: If a part of a chain is impaired in its function, the whole movement chain will be impaired! If one wants to reach lasting improvement of a symptom, the root – that is the dysbalanced supporting pier – must be treated.

Without pain returning back to center

Dr. Hashimoto developed Sotai in the 30s of the previous century. With this simple method the affected person succeeds without pain in restoring the mobility of the spinal column.

By using aimed movements going exclusively to the pleasant direction tenseness could be solved lastingly. This coupled to exhalation and sudden relaxation will shift tension from the outside to the axis of the trunk, reinforcing natural regenerating power.

Dr. Hashimoto named this principle reverse motion treatment; later it was also named the technique of sudden relaxation. Finally, the notion Sotai, a reversal of the notion Taiso – gymnastics, established itself.

The pelvis and the spinal column

The pelvis is the basis of the spinal column. A change of the opening corner of the thigh head in the articular cavity results in a shift of the pelvis shovels. This mixes up the balance of the hip and loins region.

Zeichner: Heiko SchulzeOne of the most important examination techniques in the Sotaiho serves the determination of the leg length difference and the opening corner in the hip joint (Hayashi, in 2006).

According to Dr. Isogai there is always one leg hanging more loosely than the other in the hip! In the illustration the left side is concerned. Here the femur too strongly is turned outward. Then the sacrum´s position comes more to a horizontal level, the buttok is shifted upwards. The leg appears longer, although anatomically no difference is present.

Shifted pelvis shovels have consequences for the basis of the spinal column. A light shift the SIG joint is a cause for inclined states in the loins region. To keep in the plumb this false position will be compensated by a countercurvature in the further course of the spinal column.

These mostly lateral deformities are the weak spots in the organism. Frequently it has only consequences for the movement organ. But such disturbances have certainly also influence on the functioning of the whole organism. One thinks there, e.g., of the phenomenon of the Head zones with which organ pains are projected on the body surface, or connevctive tissue zones, through their treatment the condition of inner organs could be influenced positively (Jänig, 1986).

According to Dr. Isogai there is a prearrangement for certain organ illnesses which can be determined by the leg length difference. Therefore, persons with longer right leg suffer rather from breast illnesses, while persons with longer left leg have an arrangement for illnesses of the belly space.
