I have EDS- hypermobility type. My fingers bend all the way back, my thumbs can touch the inside of my wrist, and on and on. Every joint of my body tested outside the average norm. I also have stretchy skin, POTS, low blood pressure, orthostatic intolerance, and chronic fatigue. I am lucky to see one of the world experts, Dr. Howard Levy, at Johns Hopkins near my home. He has been and always will be adamantly against me pole dancing. Every time I see him, he reminds me to "tone" my body rather than do any weight bearing exercise. I did end up tearing my forearm extensor tendon by 50% which kept me from extreme poling for at least 8 months. After that healed, I ended up tearing 3 of the 4 rotator cuff muscles completely in half. I had to have a massive rotator cuff repair. That was a brutal injury. There are a lot of successful pole dancers whom I suspect have some degree of EDS. You can tell once you know what to look for. I would caution your student to see a physician who actually knows something about EDS. It took me 20 years to get a firm diagnosis because many doctors are limited in their understanding of this condition. And even after I found a doctor, I continued to pole against doctor recommendations thinking that because I was careful and strong as well as conditioned that I would be immune. I thought my doc was ridiculous to tell me to tone with 1-2 lb weights when I knew I could lift 100 pounds, so I ignored him. Look where that got me... At the very least, get your girl to sign a release.
