Are there many people who are suffering from back problems?

Many modern people are "sit down and have a heavy back"

I am suffering from back problems such as "it is hard to walk".

腰まわりのトラブル、原因第一位は腸腰筋の緊張(ハリ)とよく言われています。

腸腰筋とは?
腸腰筋は大きく3つの筋肉の総称です。


1、小腰筋
2、大腰筋
3、腸骨筋


YUTAKA MAKE Healthcare series では

この中の2、大腰筋に着目しました。

下図のように大腰筋(青色部分)は太ももの付け根まで

繋がっています。

特殊形状の指圧体がついたヨーツナーを太ももの付け根に巻くことで 大腰筋と周辺の筋膜を刺激し、大腰筋をストレッチする仕組みです。

腸腰筋緊張緩和ベルト

The psoas major muscle, which is located deep in the body, is a muscle that is difficult to massage alone. Until now, it was standard to have a professional chiropractor perform the treatment to loosen the tension of the psoas major muscle. Our company focuses on loosening the psoas major muscle and its surrounding muscles that extend widely to the base of the thigh, and can easily and effectively loosen the psoas major muscle while living a normal life. We have succeeded in developing "Relaxation Belt Yotsuner".

Even athletes who manage their physical condition thoroughly every day may feel firm in their lower back and their performance may deteriorate. At that time, research revealed that they were relieving the stiffness of their lower back while massaging their fists against the base of their thighs. The acupressure body , which is the most distinctive feature of Yotsuner, was developed by taking inspiration from the massage that the athlete actually performed. In order to maximize the effect of the acupressure body, "hardness", "shape" and "size" were calculated, and silicon rubber was used as the material. Simply wrap the belt with this acupressure body around the thighs of both feet for 30 minutes to 1 hour a day to easily loosen the psoas major muscles. (The base of the thigh is a very delicate part. Please refrain from using it for more than 1 hour.)

Testing (Effect verification)

Osaka University of Health and Sport Sciences Faculty of Physical Education Department of Sports Science​ , "Psoas major muscle hardness", "pelvic angle", and "foot-raising angle when walking" were measured under the supervision of Professor Masanori Ishikawa.

I have never encountered a product that focuses on the psoas major muscle, and it is amazing from the perspective of a chiropractor that it was made with a focus on it, and it is a wonderful product that is epoch-making and has a unique effect. In fact, my husband is being helped. If you can make a replacement belt, I will definitely buy it, and please continue to use it. Thank you!

In the past, when I had a backache, I used to buy a massage machine or a massage chair and stick to massaging my lower back. This product is just wrapped around the thighs, but strangely it's really a little easier. It's a mystery of the human body.

​TT living in Tokorozawa City, Saitama Prefecture

I bought it hoping that my daily back pain would be resolved as much as possible. It is a great help for the price of one time to go to the manipulative teacher. Even when you can't stand it straight, you can make it crispy by wrapping it with yotsuner. that's strange. I'm happy to save time and money.
