Respiratory-related leg movements and their relationship with periodic leg movements during sleep.

ABSTRACT:

Study objectives

To describe the time structure of leg movements (LM) in obstructive sleep apnea (OSA) syndrome, in order to advance understanding of their clinical significance.

Location

Sleep Research Centre, Oasi Institute (IRCCS), Troina, Italy.

Setting

Sleep laboratory.

Patients

Eighty-four patients (16 females, 68 males, mean age 55.1 y, range 29-74 y).

Methods

Respiratory-related leg movements (RRLM) and those unrelated to respiratory events (NRLM) were examined within diagnostic polysomnograms alone and together for their distributions within the sleep period and for their periodicity.

Measurements and results

Patients with OSA and RRLM exhibited more periodic leg movements in sleep (PLMS), particularly in NREM sleep. A gradual decrease in
