Erlers-Danlos syndrome is a rare genetic disorder that affects the body's connective tissues. It causes joint instability, fragile skin, and GI issues. This condition runs in my family and I have had to undergo physical therapy to strengthen my joints to avoid pain and dislocation. Physical therapy is very helpful, but it is expensive and hard to access. Zebra is an app meant to provide free treatment of EDS and help sufferers live their lives with less pain.
