The invention claimed is: 1. Isokinetic rehabilitation apparatus comprising: a chassis including a lower portion and an upper portion; a motor-driven pedal assembly having associated therewith a pair of foot pedals and at least one hand engagement element mounted onto said chassis; a computerized motor controller operative to drive said motor-driven pedal assembly at a generally constant, selectable speed, generally irrespective of the extent to which forces are applied to the pedal assembly, pulleys mounted both on said lower portion and on said upper portion; and at least one cable extending in engagement with said pulleys connecting said at least one hand engagement element with at least one of said pair of foot pedals, at least one of said pulleys being constructed to permit disengagement of said at least one cable with said pulley, thereby changing an effective length of said at least one cable. 2. Isokinetic rehabilitation apparatus according to claim 1 and also comprising a base, configured to rest on a flat surface and wherein said chassis is selectably pivotable with respect to said base. 3. Isokinetic rehabilitation apparatus-according to claim 1 and also comprising a base; and a seat, wherein said chassis is mounted on said base, and said seat is selectably horizontally positionable with respect to said base and rotatable with respect to said base. 4. Isokinetic rehabilitation apparatus according to claim 3 and wherein said chassis is selectably pivotable with respect to said base. 5. Isokinetic rehabilitation apparatus according to claim 4 and wherein said chassis is selectably pivotable with respect to said base between a first operative orientation, wherein said at least one hand engagement element is located between said chassis and said seat, and a second operative orientation, wherein said at least one hand engagement element is located on an opposite side of said chassis from said seat. 6. Isokinetic rehabilitation apparatus according to claim 1 and wherein said motor-driven pedal assembly comprises: a foot pedal assembly axle, which is fixed to a toothed gear, driven in motion by a motor; first and second foot pedal support shafts, mounted onto said foot pedal assembly axle; and first and second foot pedal mounting assemblies which rotatably support foot pedals and which are mountable onto said first and second foot pedal support shafts in two possible orientations, which correspond to positions of said foot pedals at two different distances from said foot pedal assembly axle. 7. Isokinetic rehabilitation apparatus according to claim 1 and wherein said computerized motor controller is operative to provide an output indication of resistance to rotation of said motor-driven pedal assembly at a generally constant speed. 8. Isokinetic rehabilitation apparatus according to claim 7 and wherein said output indication is a real time operator readable output indication. 9. Isokinetic rehabilitation apparatus according to claim 7 and wherein said output indication is a summary operator readable output indication. 10. Isokinetic rehabilitation apparatus according to claim 1 whereby rotational motion of said foot pedal assembly results in reciprocal motion of said at least one hand engagement element along a reciprocal motion axis, and wherein at least one of said pulleys, being closest to said at least one hand engagement element, is rotatable relative to said chassis about at least first and second mutually orthogonal axes.
