Periodic limb movements in patients with suspected sleep apnea without comorbid conditions

Introduction In patients with clinically relevant periodic limb movements (PLM) and obstructive sleep apnea (OSA), symptoms and risk factors overlap [1]. However, a mechanistic link between both conditions is vague [2]. Previous studies focused mainly on associated comorbidities and their impact on PLM and OSA. Thus, little is known about PLM in healthy patients with suspected OSA.
