Safety

Kinbaku World is an encyclopedia, not a course. Rope bondage carries real risk of injury, and it should be learned in person from an experienced teacher.

Nerve injury is the best-documented risk

A 2023 case series in the journal Cureus examined ten people injured during full-body suspensions. Nine of them had injuries to the radial nerve, which runs along the back of the upper arm; others involved the axillary and femoral nerves. The authors point to the course of the radial nerve near the deltoid as the area to protect. (Khodulev et al., 2023)

What experienced teachers stress

• Watch for numbness, tingling, weakness or loss of grip in the hands, and untie immediately if they appear.
• Keep safety shears within reach whenever someone is tied.
• Agree on limits and signals before tying, and keep talking during it.
• Never leave a tied person alone.
• Suspension needs dedicated in-person training; do not attempt it from pictures or videos.

Pages about ties on this site describe what a tie is and where it comes from. They never contain step-by-step instructions.
