The warm-up phenomenon
This phenomenon was described along with the disease by Thomsen in 1876 but its etiology remains unclear.Patients report that myotonia congenita may present itself in the following ways (this is from first hand experience). If the person is sedentary and then decides to walk up a set of stairs, by the third or fourth step their leg muscles begin to stiffen significantly, requiring them to slow down almost to a complete stop. But as the muscles loosen up, a few steps later, they can once again begin to climb the steps at a normal pace. If this person plays any kind of a sport, a good warm-up is mandatory. Otherwise if they need to quickly and intensively use their muscles, such as in a sprint race or a basketball game, their muscles will freeze up, causing them to slow down or almost come to a complete stop. But once the muscles are warmed up, they can once again function normally. This can happen in various muscles, even in muscles such as the tongue.
