Features of the Pronex Pneumatic Cervical Traction Device: Maintains the natural curve and alignment of the neck. Easy to use, comfortable and non-threatening. Reduces pharmacy bills, minimizes lost workdays, and often eliminates the need for ongoing office visits and physical therapy. Pronex cradles the reclining patient's head and neck on two soft foam cushions. An air-inflated bellows is capable of providing up to 35 lb. of continuously adjustable traction. As the bellows expands, it lifts the head upward supporting the cervical curve and maintaining an even distraction in the anterior and posterior cervical discs. Patients have total control over the amount of traction applied. Squeezing an inflator bulb increases the pressure, a release knob gently reduces it.
