ABSTRACT:
A portable exercising apparatus (10) adapted for use by a patient as a stand-alone unit includes an elongated tube (12) and a power slide (16) having a friction mounting on the tube (12). A force measuring mechanism (26) is coupled to the tube so as to measure external forces exerted in moving the tube (12) relative to a handle rod (24) partially received in one end of the tube (12). The mechanism (26) includes a gauge dial (32) with a pointer (34) coupled to a pinion gear (52). The pinion gear (52) engages a rack (64) mounted to a slide rod (56) received within the tube (12) and secured to the handle rod (24). Movement of the tube (12) relative to the slide rod (56), resulting from forces exerted on the power slide (16), causes rotation of the pinion gear (52) and dial pointer (34).
