Research Article: Temporal association between leg movements and respiratory events in patients with obstructive sleep apnea: description and differences between the AASM and WASM scoring criteria

Date Published: 2023-05-06

Abstract:
To describe the temporal association between leg movements (LMs) and respiratory events in patients with obstructive sleep apnea (OSA), and to quantify the difference in scoring respiratory-related leg movement (RRLM) between the American Academy of Sleep Medicine (AASM) criterion and the criterion recommended by the World Association of Sleep Medicine (WASM).

Introduction:
Several types of involuntary limb movements may occur during sleep. These movements may be isolated in time and occur in response to external triggers (e.g., noise and light) or seemingly spontaneously. Other limb movements may occur repetitively in series. Periodic limb movement during sleep (PLMS) is characterized by repetitive involuntary flexion/extension of the big toe and ankle, and occasional flexion of the knee and hip [1]. The American Academy of Sleep Medicine (AASM) defines a leg movement (LM) as an…
