"Astasia-Abasia is also known as Blocq's Disease, after Paul Blocq, the French doctor who first described it. It's the inability to stand or walk properly, but there's more to it. At first, a person with this condition appears very drunk. Patients lurch when they try to stand or walk. Patients seem dangerous to themselves. They overbalance extravagantly, always catching themselves at the last moment. But that's the condition — they always catch themselves.
People with Blocq's Disease almost never hurt themselves. They only fall when a doctor, a loved one, or a soft place on the ground is available. Often this condition is in response to stress. The most famous case of this happened in the 1960s, when not one but two cadets at West Point came down with the condition, doctors believe as a response to the pressure of training at the prestigious school."
