Abstract: An orthotic substantially precludes a human wearing it from rolling from her or his side to her or his face or back. The garment (such as a vest or jacket) has an open top portion, a front that can be closed by fasteners, a substantially closed rear, a first receptacle on the front, and a second receptacle on the rear and functionally cooperating with the first receptacle. Third and fourth receptacles are preferably also provided, the first and second receptacles on the left side of the garment, and the third and fourth on the right side. The garment may be primarily of a stretchable mesh fabric. A cylindrical or prismatic bolster (e. g. of firm foam or rubber) is insertable into, and removable from, each of the first and second receptacles, or each of the third and fourth receptacles.

Abstract: A cervical collar dimensioned to fit a human patient's neck is constructed primarily of foam. It has a foam body with a main top surface and a bifurcated (“M”-shaped) top portion which extends significantly upwardly from the main top surface so as to allow the midline of the occiput to float, thereby minimizing ulceration-causing pressure. The foam body may have a density of at least about 1.4 lbs/ft3, and a mound like bottom projection may extend from a main bottom surface thereof. The foam body may have slits formed in it, and a rigidity-enhancing element is inserted into a slit. By inserting different rigidity-enhancing elements the rigidity of the foam collar may be adjusted. The rigidity-enhancing element may have a C-shape with a hinge spring between two rigid portions.
