The Effect of Positional Device on the Obstructive Sleep Apnea in Patients With Ischemic Stroke

Avoidance of supine positioning was achieved by use of the commercially available ZZoma Positional Device, which is the FDA cleared class II positional medical device. The device is 12 x 5.5 x 4 inches in size and made of lightweight semi-rigid synthetic foam. It is contained in the nylon material with an associated Velcro belt. Zzoma is a positioner worn around the upper torso to restrict patient movement from side to supine.

A lumbar (abdominal) binder is made of an elastic fabric with Velcro closure. Subjects wore the prefabricated lumbar corset during sleep and were positioned ad lib.
