A portable parallel walking bar assembly which can be rapidly assembled, disassembled, transported and stored when not in use. A pair of collapsible parallel bars can extend to a length of 8.5 feet and collapse to a length of only 4 feet. Support stanchions having an adjustable height between 24 and 40 inches attached to the collapsible parallel bars for stabilization. Each support stanchion has a flat cross-member, which spans a width of the assembly and provides a base of support. On opposing ends of each cross-member, a vertical support extends up and is adjustable in height. The vertical supports respectively connect to the collapsible parallel bars in such a way that the assembly is stable and secure for rehabilitation purposes, specifically for persons with physical disability to apply force through the collapsible parallel bars to support their body weight as needed while walking.
