Abstract: Lumbar distraction is an effective treatment for back pain. However the discomfort and morbidities associated with vertical inversion has limited its use. The Lumbar Distraction Chair delivers a gentler lumbar distraction without the discomfort of being suspended vertically. The device is a modified office swivel chair with inward folding arm rests that secure the patient's legs on the chair seat. The patient positions him/herself onto the device with their back lying on the floor with hips and knees flexed. The arm rests of the chair fold inwards and hold the patient's legs securely onto the seat. A pneumatic telescopic stand elevates the seat, which also lifts the patient's legs hips and lower back off the ground by several centimeters. This provides lumbar distraction to the lower back. In this position, pain and inflammation is alleviated. This permits the muscle cell relaxation, recuperation and repair.
