Periodic Limb Movement Disorder (PLMD) refers to repetitive cramping or jerking of the leg during sleep that is so powerful it can wake you up during the night. The same disorder can occur during the day when you are awake (PLMW), but the nighttime version (PLMS) is more common and disruptive. The medical community is still unaware of what causes primary periodic limb movement disorder, although it is assumed to result from abnormal patterns of nerves passage from the brain to the limbs. While the specific causes of periodic limb movement disorder are unknown, the problem is a real one that merits investigation by a medical professional.
