Oral appliance titration in patients with obstructive sleep apnea induces the appearance of periodic limb movements.

STUDY OBJECTIVES: Oral appliance (OA) therapy is considered a first line choice of therapy for some patients with mild or moderate obstructive sleep apnea (OSA) and an alternative form of treatment in those intolerant of continuous positive airway pressure (CPAP) use. According to several studies, periodic limb movements (PLM) appear during effective treatment of OSA with CPAP, but a similar phenomenon has not been described with the use of oral appliance. Herein, we describe the incidence of PLM in patients with OSA who underwent oral appliance therapy titration…
