Pes cavus (pess KAY-vus) is a foot with an abnormally high arch that does not flatten out when weight is placed on it. Because the arch stays raised, more pressure falls on the ball and heel during standing and walking. A high arch is often considered a hallmark of CMT, though it is not universal, and the opposite, pes planus or flat foot, can also occur in the disease. A high arch can also signal an underlying neurologic disease, which is part of why it draws attention in CMT.
When Medicine Lost Its Compass
Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.
