Chapter 2160: line with translation of chapter title

Seeing his System Panel, Zheng Ren was stunned for a moment.

"Hey, Boss, this move is as difficult as that intracardiac intervention surgery you did!" Su Yun's emotions soared, and she was practically bursting.

Standing on the battlement, this guy wasn't idle either; he tried the young man's move, but soon realized he couldn't do it.

Before Su Yun could finish her sentence, she saw the man in front of her "jump" up.

The stiff position of his arm fluctuated like a tide, carrying a strange rhythm, and it indeed looked quite cool.

The key is that half of his body is stiff while the other half is soft; this visual contrast leaves a deep impression.

Su Yun squatted on the wall battlement, carefully observing the guy's movements in front of her.

Half of his body, including his abdominal muscles, followed the left arm's movement with a regular fluctuation; this guy is awesome!

To reach this level in mechanical dance, one cannot do it without ten years of hard training.

Zheng Ren stood aside, frowning as he watched; he did not act in the First Time.

The young man's muscles trembled extremely evenly on one side of his body, his limbs slightly stiff; to Zheng Ren it looked like a pathological episode, but to Su Yun and the watching elders it was absolutely not illness but dance.

The stiff part is not fixed; it keeps moving, and even a motion that defies biological instinct appears intermittently.

The hardest part of this "movement" is that his left half and abdominal muscles are moving while the right side of his body remains normal.

Yet precisely because of that, it looks harder than full-body trembling mechanical dance and also possesses an asymmetrical beauty.

"Whoa~" the nearby elders burst into applause.

Having danced in the square for years, they knew just how difficult the young man's moves were.

Watching, the muscles trembled and kept shifting position, but that was definitely something he had trained himself to do.

It had rhythm, carried a miraculous cadence, and even Zheng Ren zoned out for a moment.

But he immediately cross-checked with the System Panel to confirm the issue, then jumped straight down from the battlement.

"Excuse me, make way."

"Excuse me, make way."

Zheng Ren kept saying it, but the elders were so interested that nobody paid him any heed.

Seeing Zheng Ren about to go in, Su Yun looked a bit anxious and also confused, so she jumped down and asked, "Boss, what's wrong?"

"Suspected stiff-person syndrome." Zheng Ren said in a low voice.

If there were a dozen or several dozen burly men ahead, Zheng Ren wouldn't find it so difficult; he'd use brute force to part the crowd and charge straight in. They're just ordinary people; they can't stop him.

But facing a crowd of elders, they left him stumped.

If he forced his way in and two people ended up on the ground, what would he do?

Even if nothing were wrong, sending them to the hospital for a full checkup would require him to accompany them with a smile, like dealing with a grandchild—also not worth it.

"Stiff-person syndrome?" Su Yun blinked, then immediately snapped out of her mistaken train of thought.

While he was thinking, Zheng Ren had already picked up his phone and dialed the Emergency Rescue Service call.

After Su Yun waited for the call to finish, she immediately said, "Are you sure? It does look a bit like it."

"Look at his foot, the one without a shoe—Babinski sign positive."

Babinski sign positive is the most important sign of corticospinal tract damage; positivity manifests as dorsiflexion of the big toe, with the other four toes fanning out.

Su Yun also noticed this; she had just thought the guy was exerting force with his toes.

At this moment, recalling it, the Boss's words were not wrong.

"It's not exactly typical stiff-person syndrome; maybe it's stiff-limb syndrome." Seeing that he couldn't get in either, Zheng Ren explained to Su Yun that the patient's condition wouldn't imminently threaten life, so he wasn't in a hurry.

"In general, domestic patients often first show symptoms in the masseter muscle; as the condition progresses, the waist, neck, trunk, and proximal limb muscles become tight and stiff, limiting voluntary movement, making it impossible to bend the waist while walking upright, and so on."

"His movement, is it a sustained fluctuation?" Su Yun asked in surprise.

Zheng Ren nodded.

In the early stage of stiff-person syndrome, there are intermittent aches in the abdomen, trunk, and muscles, with a sensation of tightness, non-specific and transient, later spreading to the limbs.

As the disease progresses, sustained or fluctuating stiffness commonly appears in the trunk, limbs, and neck muscles; the abdominal muscles become board-like or stone-like firm, and both agonist and antagonist muscles are affected.

The patient before them, because the fluctuation was so rhythmic, even Su Yun mistook it for dancing.

As soon as Zheng Ren reminded her, Su Yun immediately realized the problem.

"I said it, this morning in the community battling a group of elders in square dance—surely there's something wrong." Su Yun let out a sigh.

But his tone carried a hint of regret.

Just moments ago, I thought he was a god-level mechanical dancer; a fleeting glance sparked my interest, and I wanted to battle the elders in square dance in the community.

Who would have thought it was actually stiff-person syndrome.

"Have you ever seen a tetanus patient?" Zheng Ren asked.

Su Yun shook her head.

This disease is far less common in Di Du than various rare diseases; whoever gets injured doesn't get a shot, but waits for tetanus to break out.

Zheng Ren chuckled, "I've treated one case in Hai Cheng."

"I heard Chang Yue say that; it's really regrettable."

"In 1967, McQnillen once considered this disease an unidentified chronic tetanus, but Tarlor et al., through animal experiments, observed no experimental tetanus occurring with the sustained muscle rigidity characteristic of this disease, thus ruling out that possibility."

"Besides, tetanus doesn't affect just one side of the limbs while leaving the other side fine." Su Yun said.

"This patient is rather special."

"Are you planning to send him to the hospital and give him an injection of diazepam?" Su Yun asked.

Diazepam is one way to differentiate stiff-person syndrome from tetanus; in tetanus patients, muscle rigidity does not respond to intramuscular diazepam.

In stiff-person syndrome patients, intramuscular diazepam can alleviate symptoms.

Zheng Ren nodded.

"He doesn't seem to be in much pain; isn't it said that muscle spasms usually cause severe pain, even leading to muscle tears or fractures?" Su Yun tried to recall that guy who battled the elders in square dance.

"Not all of them, you just said most of them just now." Zheng Ren said, "Did you see the flowers?"

"I saw it, I thought it was a proposal." Su Yun said, a hint of a mischievous smile appearing at the corner of her mouth.

"I think it's emotional frustration, maybe a breakup or something, that stimulated him and caused this situation." Zheng Ren said, "It's fine, go to the hospital and get a shot of tranquilizer and you'll know."

Chatting, the Emergency Rescue Service vehicle arrived.

Hearing the sound of the 120 Emergency vehicle, the old men and women reluctantly made way.

At this moment, if one were to block the doctor and delay emergency treatment and rescue, ordinary people wouldn't do such a thing.

Seeing it was the 912 120 Emergency vehicle, Zheng Ren called Su Yun to leave.

PS: I had saved up a stack of books for a while; today I read them to my heart's content. Suddenly I discovered that Xia Hua Niang is the author of the dual-serial "Eternal Life" and "Escape"... Lately I really don't want to think about anything else; could it be that Xia Hua Niang has become so diligent? Suddenly I felt a great pressure~~ I need to work harder.
