Dear all, As we all know, kinbaku is a risky practice that can lead to serious injury. While I find that there are some great resources that focus on nerve placement and areas prone to nerve injury in kinbaku, I feel that there are limited resources for practically assessing blood flow restriction. How much occlusion is within safe limits and for how long? How do we discern if the occlusion is arterial or venous? What are the implications of either, and how long can we leave someone tied in a position where there is visible discoloration. Why do some people tend to discolor a lot faster than others? I am currently working with a trained medical practitioner in this area to come up with some practical evaluation techniques and more detailed information starting with a focus on the vascular system. As part of this project, we are also looking for some reference photos of any bind you have done or been tied in, where there is visible discoloration or occlusion.

Please feel to also comment with:
・Any questions you have, ・Any resources you know of which focus on this area. I thought that I would also share this interactive 3-D diagram for reference. https://www.healthline.com/human-body-maps/shoulder-nerves-vessels#1 https://www.healthline.com/human-body-maps/anterior-tibial-artery#1
