Abstract
Abstract An assist bar is provided for facilitating a standing chiropractor in the manipulative treatment of a prone patient's spine while the patient is supported on a leg support section of a chiropractic table of the type having a body support section for the patient's body pivotally interconnected with the leg support section. The assist bar includes a connector at one end for securing the bar to the leg support section remote from the pivotal interconnection of the section with the main body support section. The assist bar extends outwardly of the leg support section and a handle is provided adjacent an outer end portion for facilitating a chiropractor in manipulating the patient's lower body up and down or side to side while making adjustments in the patient's spine with the other hand on the patient's body on the body support section.
