A belt is provided with an inflatable bladder which, when inflated, is permitted to expand toward an interior of the belt and prevented by a barrier from expanding toward an exterior of the belt. A pressure gauge indicates the pressure within the bladder, and the gauge is fixedly displaced relative to the belt and the user such that the gauge may be viewed by a user when the belt is worn without significantly moving the cervical spine substantially out of a neutral posture.
