What are symptoms of periodic limb movement disorder (PLMD)?
Symptoms of PLMD are usually leg movements with the extension of the big toe in combination with a partial flexing of the ankle, knee, or hip. Movement of the legs is more typical than movement of the arms. It may wake you up briefly, resulting in fragmented sleep.You may not be aware of these movements.
