Periodic Leg Movements During Sleep

Periodic leg movements during sleep (PLMS) are a frequent finding in nocturnal registrations that include tibialis anterior electromyographic signals. Different PLMS scoring rules exist and can have major impact on frequency, which tends to be underappreciated. There is no consistent evidence causal risk factor for clinically significant outcomes. Several critical open questions identified need addressed, including but not limited the consideration of full range all sleep-related movement activity.
