| 1. A spinal treatment apparatus for applying a spinal treatment force to a patient, comprising:
a. a base portion;
b. a telescoping support mounted on and extending upwardly from the base portion, the telescoping support including a bottom
member and a top member, the top member moveably engaged with the bottom member so that the top member has a retracted position
and an extended position, the telescoping support constructed so as to be capable of withstanding a force imparted on the
top member, the force corresponding to the spinal treatment force, while in both the retracted position and the extended position;
c. a spinal distraction device mounted on the top member of telescoping support that applies the spinal treatment force to
the patient;
d. a linear electrical motor that moves the top member vertically relative to the bottom member, thereby moving the spinal
distraction device to a selected vertical position;
e. a treatment bed, capable of supporting the patient, affixed to the bottom member of the telescoping support; and
f. a counterweight affixed to the bottom member of the telescoping support to balance at least a portion of the force imparted
on the top member.
