Auricular therapy, originally derived from auricular acupuncture, involves
stimulation at specific acupoints on the outer ear with needles, pellets (Semen vaccariae), magnetic
pearls and electricity [22]. Auricular acupressure (AA) is one of the typical types applied in
diverse clinical conditions including sleep problems. Our preliminary work showed that AA
adding to basic care (including sleep hygiene and sleep medications if necessary) achieved improvements
on sleep quality, efficacy and duration in hemodialysis patients with severe insomnia
[23].
