"Hehe," Zhou Da thought that the words he said from the meeting to the present did not offend Ji Ke, this kid didn't know what medicine to take, and he came up like this, he really thought he was a soft persimmon!

"We came today, mainly because we encountered a little incurable disease, I heard that there is a coach here, is the best personal trainer in the province, so I came to solve the puzzle and ask for guidance. ”

"The best in the province, who said that?Xiao Ji, when did you have this name?" Li Jiang, who was already suspicious of Zhou Da and Cui Long, suddenly realized at this time that the person who came was not good! Quickly interrupted and reminded his boyfriend not to jump into the pit.

As soon as Li Jiang interrupted like this, the others also reacted, Nima, this is a door-to-door trouble! I don't know how many eyes Lord Ma has, right?

Personal trainers, don't look at the usual temper, in fact, they are quite angry.

When I usually get along with members, I have to force a smile and flattery, who lets me do this job! But when I encounter something, I will think about making it bigger, bigger and bigger!

Anyway, labor and management eat according to their ability, as long as they don't offend members and don't violate laws and disciplines, it's fun to make things bigger!

A group of people dispersed tacitly, faintly surrounding Zhou Da and Cui Long in the middle.

"What do you ask?" Ji Ke took the time to ask Zhou Da what questions he had, and his tone was still quite unpolite.

Of course, he could hear the trap in Zhou Da's words, but what did it matter? He was confident that there would be no problem in crushing Zhou Da and the two of them with his own strength.

"That's the case, a friend of mine has some sciatica and asked me what I can do, I just heard about Coach Ji's reputation, why don't you come here to ask for advice!" Zhou Jie thought for a while and threw out a question.

Sciatica, as the name suggests, is pain caused by the sciatic nerve, along the course of the sciatic nerve, the pain ranges from the buttocks, back of the thigh, back of the calf, and dorsolateral of the foot.

"If it weren't for the pain caused by nerve inflammation, I could have helped," Ji Ke first cleared up areas that were impossible for private training to touch.

Sciatica is divided into two causes: primary and secondary;

Primary pain is caused by inflammation of the nerves themselves, and the scope of work of the personal trainer does not cover much in this area, but the probability of primary nerve pain is not high.

Secondary pain is the main cause of sciatica and is a business skill that a good personal trainer should master, because secondary pain is mainly caused by external compression of the nerves.

With the system in hand, whether it is primary or secondary, Ji Ke can deal with it easily, but the problem is that he does not have any academic qualifications or learning background to explain why he can solve primary neuralgia, so he can only give up this part of the business first.

"He checked, and it's not nerve inflammation. Zhou Da felt a little surprised, there are not many coaches who know about nerve inflammation, and many coaches don't even know their own muscle field, let alone dabble in the nerve field.

Zhou Da judged from Ji Ke's words that Ji Ke at least has quite good attainments in the muscle field, otherwise where would he get the energy to dabble in nerves?

"That's easy," Ji Ke didn't change his face and talked eloquently.

The sciatic nerve, which originates from the spinal cord at the lumbosacral region, passes through the pelvis, passes through the sciatic foramen magnum, reaches the buttocks, and descends along the back of the thigh to the dorsolateral side of the foot;

In order to fully understand how the sciatic nerve is compressed by external forces and causes pain, it is necessary to have a simple understanding of the pelvic structure.

The pelvis is made up of three bones, namely the ilium (the largest area, located above), the pubic bone (anterior and inferior to the ilium, where the reproductive organs are stored), and the ischia (below the iliac bone, behind the pubis, which is responsible for sitting);

There is a ligament between the ischial bones and the sacrum of the spine, which just circles an almost circular hole, and this hole is the greater ischial foramen!

The foramen magnum is enclosed by a muscle called the piriformis muscle.

The sciatic nerve is from below the piriformis muscle, against the ischia, out of the pelvis, and into the buttocks;

In the buttocks, the sciatic nerve is located above the three muscles, which are the superior ma, the obturator internal muscle, and the inferior ma.

Secondary sciatica is caused by pain in the piriformis muscle, superior muscle, obturator muscle, and inferior muscle, and spreads to the thighs, calves, and feet, only as a result of nerve pain in the buttocks passing downward.

The root cause of this pain is that the piriformis muscle is too tense and developed, and the thick piriformis muscle is squeezed into the sciatic nerve.

The piriformis muscle originates from the lateral aspect of the sacrum at the lower end of the spine and terminates at the greater trochanteric of the femur (posterior to the upper end of the femur),

Its function is very simple, the sacral side is stable, and the force on the femoral side will make the thigh externally rotated and abducted (the outer thigh is eight, the side of the leg is extended);

In the same way, the pelvic tilt and thighs long-term practice of external eight and abduction movements will exercise the piriformis muscle and make it thick;

That's why we often see people who sit for a long time and are prone to sciatica.

"What I said is very clear, right?" Ji Ke explained in detail the causes of secondary sciatica, popularizing the most comprehensive information, "As for the stretching and release of the piriformis muscle, you don't need me to teach you, right?"

Ji Ke picked up the water cup and took a sip, wet his lips and moisten his throat, two sets of heavy weight squats made the body desperately need to replenish water, he didn't drink water because of the dry mouth he said!

Ji Ke is not worried at all that Zhou Dazhi knows how to stretch the piriformis muscle; after so many years, he is still working as a coach in the provincial staff fitness center, if he doesn't even know how to stretch and release the piriformis muscle, it is too much to underestimate the requirements of the staff fitness center for the coach's business level.

He really doubts, Zhou Da doesn't understand how to solve this problem, it's a pretense to ask himself for advice, the relationship between the piriformis muscle and the sciatic nerve can be said to be basic sports rehabilitation knowledge, it is not unfathomable at all, looking at Zhou Da's age, thirty years and above, how can he not understand these? !

Zhou Da is indeed only the relationship between sciatica and the piriformis muscle, and even he has helped some members cure sciatica;

It is true that simply releasing the piriformis muscle can quickly relieve the pain of sciatica, but it is impossible to say that it is completely cured, and this is also the back hand of his preparation.

"The stretching of the piriformis muscle, I am naturally clear, but the question is, how to completely cure it?" Zhou Da followed his own routine and started the next step.

"Isn't it? You even have to ask me about the posture adjustment of the pelvic backward tilt? Although it is more troublesome than determining the position and stretching of the piriformis muscle, it can be regarded as a big thing!" Ji Ke pretended to be surprised, and did not accept Zhou Da's move at all, directly questioning Zhou Da's level, and taking offense as defense.

"Forget it, since you come to ask for advice, I can't save your face, Mr. Zhu, you talk to him about how to adjust the retrograde pelvis. ”
