Abstract: The present invention relates to an orthotic lumbar support garment intended to be worn under a patient's clothing and affixed around the abdomen of the patient generally positioned above the patient's hips. The orthotic lumbar support garment of the present invention is in the form of a belt-like apparatus which is configured to prevent, restrict or reduce the motions which would aggravate various spinal conditions existing in a patient, such as spondylolithesis (LS), spondylosis, or a slipped disk condition, by applying lateral pressure to the spine from the abdomen through conformable chambers disposed on the belt adjacent the patient's abdomen.
