ABSTRACT:
A tractor for the treatment of deformities of the spine comprises a plate of rigid material such as plastic having a raised peripheral rib extending outwardly from the plate in the form of an elongated figure 8 which encloses a substantially cylindrical end portion at each end interconnected by a central connecting portion space which is covered by a flexible elastic membrane so as to form two airtight chamber portions at each end and a narrow central connecting portion which communicates therebetween. The end portions may be inflated outwardly with the use of a portable hand pump or bellows connected thereto and the device is adapted to be engaged with a brace applied around the person's body.
