Shibari safety: nerves, communication and when to get help

Shibari is the Japanese art of tying a person with rope. Like any practice that puts pressure on the body, it carries physical risks, and the one that sources stress most is injury to the nerves. This page sets out, in plain words, what two public sources say about shibari safety: a small study published in a medical journal and a safety flyer written for the bondage community. It is general information, not medical advice, and it is not a tutorial: it describes no ties and no positions. For anything that concerns your own body, a doctor or a nurse is the right person to ask.

Where this information comes from

Two sources stand behind this page, and neither is an official health recommendation. The first is a paper published in 2023 in the medical journal Cureus. Its authors collected accounts from 4 experienced rope practitioners and from people who had been hurt, and they identified 10 people with 16 nerve injuries. The second is a safety flyer from Twisted Windows, an education website about bondage safety, written as a quick reference to use alongside classes.

The study has limits, and its authors say so themselves. The group was small, it was recruited online and through personal networks, and it included only people who had been injured. The study therefore cannot say how common injuries are among everyone who practises. What it does show, in the authors' words, is that the risk of nerve injury is not negligible.

Why nerves matter

The flyer calls nerve damage a serious risk with bondage, especially suspension, when the body is lifted off the floor by rope. It can affect feeling or movement, it can range from mild to severely disabling, and it can last for months or even be permanent.

In the study, the radial nerve was the one most often affected: 9 of the 10 people and 13 of the 16 injuries. This nerve runs very close to the bone of the upper arm, which the authors see as a likely reason for its exposure to pressure from outside. When it is compressed, the people in the study described numbness on the back of the wrist and weakness in lifting the wrist and straightening the fingers, from moderate weakness to complete paralysis. All but one of the injuries appeared straight after a full suspension.

The authors report recovery times from 2 minutes to 5 months and describe the outlook as generally favourable. They write that recovery depends on how severe and how long the compression was, on individual factors and on prompt medical attention, and they warn of a risk of repeat injury when precautions are not taken. The flyer is more cautious, saying that nerve damage can last for months or be permanent.

Warning signs, and what the flyer advises

The flyer lists the signs that may point to nerve damage: numbness, tingling, tightness, weakness, burning, and sharp or shooting pains. It advises acting at once, by removing or redirecting tension, shifting the ropes or changing position, and, when in doubt, untying completely, starting with the affected limb.

Two points from the flyer are easy to miss.

• The person doing the tying cannot detect many nerve injury symptoms. Only the person who is tied can feel them, which is why speaking up matters.
• Nerve damage happens in stages. Acting at the first signs can keep a minor injury from becoming a major one.

The flyer also says that nerve damage can occur without warning or symptoms, even with an experienced partner who does everything right. No amount of care removes the risk completely, and that is one more reason to learn from people who teach safety first. The flyer encourages people to learn to tell warning signs from intense but harmless sensations, and to say what they notice.

What makes injury more likely

According to the flyer, several factors contribute.

• The place on the body. Muscle and fat tend to protect, so the upper limbs are generally at higher risk than the lower ones.
• How long the rope presses, and how hard.
• Positions that put the body under strain.
• Differences from one person to another in how vulnerable the nerves are.
• Cold, which increases the risk, and distractions such as other stimulation or an audience.

The flyer also advises against using bondage to put large amounts of tension on joints: wrists, elbows, knees, armpits and groin. It names the radial nerve, in the middle of the upper arms, as another common injury site. The study adds that full suspension carries a higher risk of compression injury than partial suspension.

Other risks the sources name

Nerves are not the only concern. The authors of the study write that rope bondage can cause nerve damage with loss of movement and feeling and, in severe cases, deaths, and that being upside down during a full suspension raises the risk of falls, head injuries and asphyxiation.

The flyer adds that fainting or falling can cause serious injury, and it lists causes of falls: furniture tipping over, anchor points failing, ropes breaking and walking with bound arms. It advises avoiding bondage around the neck, or from the genitals to an external point, and being careful when a gag is combined with bondage, always with a safe signal. It suggests settling bathroom and hydration needs before starting, thinking about warming up before intense play, and telling a partner about your health history, in particular diabetes, asthma, joint problems, phobias or triggers, seizures, nerve damage and medications.

What the authors suggest to lower the risk

The study ends with a list of preventive measures. In short:

• Use techniques that spread pressure evenly and avoid pressing hard on sensitive nerve paths, such as the radial nerve.
• Limit how long a full suspension lasts.
• Set time limits and check in regularly with the person who is tied, asking about pressure or discomfort.
• Position the body and limbs well, and avoid extreme angles.
• Keep communication open, so that anything unusual is said early.
• Learn anatomy, nerve paths and safety guidelines through proper training.

The authors add that more research and expert agreement are needed before complete and standard safety guidelines can be written. The basics in the flyer point the same way.

• Communicate before, during and after.
• Negotiate before play, covering signals, limits, expectations and rope marks.
• Stay completely sober.
• Keep safety shears within reach, and practise using them.
• Never leave someone alone while tied.
• Learn safety and technique in classes before using rope in a scene or in the bedroom.

When to get help

A doctor or a nurse is the right person to ask about numbness, tingling, weakness or pain that appears during or after rope work, or that does not go away. You do not need to be sure that it is serious first, since assessing it is a professional’s job. The authors of the study write that seeking timely medical attention and applying safety measures matter for recovery. In an emergency, call the local emergency number.

Talking about it before and after

Safety is easier when it belongs to an ordinary conversation. A negotiation checklist, safewords and aftercare show how to have it. Shibari: what it is and where it comes from gives the wider picture, and how to learn shibari safely explains how to choose a teacher. The section Desire and exploration gathers the other guides on this theme.

Questions about shibari safety

Is shibari dangerous?

Any rope practice carries risks. The sources describe injury to the nerves as a serious risk, above all in suspension, and they say that care lowers the risk without removing it.

Which nerve is injured most often?

In the study, the radial nerve in the upper arm: 9 of the 10 people and 13 of the 16 injuries.

How long does a nerve injury last?

The flyer says that it can last for months or be permanent. The study reports recoveries from 2 minutes to 5 months.

Can an experienced partner prevent every injury?

No. The flyer says that nerve damage can occur without warning, even with an experienced partner who does everything right.

Can the person who ties notice a nerve injury?

Not always. According to the flyer, the person tying cannot detect many of the symptoms, so the person who is tied needs to say what they feel.

What does the flyer advise at the first sign?

To act at once: remove or redirect tension, shift the ropes or change position and, when in doubt, untie completely, starting with the affected limb.
