A therapeutic table for use when applying traction to a patient's lumbar region when the patient is supported on the table in a prone position comprising:

• a frame;
• an upper-body section and a lower-body section each having a proximal end and a distal end, said table sections being mounted on said frame with their proximal ends located adjacent to and disposed opposite one another, said lower-body section being slidably mounted on said frame for longitudinal movement with respect to the upper-body section between a first retracted position and a second extending position to adjust the effective length of the table;
• said upper-body section having:
• (i) a first portion having a length extending from said proximal end toward said distal end which has a sufficient length to underly and support the upper body and head of a patient when the patient is resting in a prone position on said table;
• and
• (ii) a second portion having a length extending from the first portion to the distal end thereof;
• upper-body restraint means for restraining the patient with respect to the upper-body section, said restraint means including a pair of spaced hand grip means which are projecting upwardly from said second portion of said upper-body section, said hand grip means being spaced from said first portion to a sufficient extent to require a patient resting in said prone position on said first portion to reach above the head in order to manually engage the hand grip means;
• said lower-body section having a sufficient length between its proximal and distal ends to underly and support the lower body portion of a patient resting in said prone position on said table;
• anchor means on said lower-body section;
• a pelvic harness adapted to fit around the pelvic area of a patient, said pelvic harness being connectable to said anchor means for movement therewith;
• extensible cylinder and piston means communicating with said lower body section and operable to cause said lower-body section to reciprocate to and from between said first and second position to cyclically apply traction to the lumbar region of a patient when a patient, wearing the harness, is resting in a face down prone position on the table with the pelvic harness secured to said anchor means and when the patient manually engages the hand grips;
• said upper body restraint means being completely releasable by the patient as said second table top member lower body section moves with respect to said upper body section to thereby permit the patient to limit the amount of traction placed on the lumbar region.

In a therapeutic table for use when applying traction to a patient's lumbar region when the patient is supported on the table in a face-down prone position of the type having upper-body and lower-body sections mounted on a frame, the lower-body section being slidably mounted on said frame for movement with respect to said upper-body section between a first retracted position and a second extending position to adjust the effective length of the table, the improvement of;

• upper-body restraint means for restraining the patient with respect to the upper-body section, said restraint means including a pair of spaced hand grips which are rigid and which project upwardly from said upper-body section, said hand grips located on said upper-body section such that it is necessary for a patient resting in said prone position on said upper body section to reach above the head in order to manually engage the hand grips;
• said upper body restraint means being releasable by the patient as said upper-body section slides relative to said upper-body section whereby the patient may limit the amount of traction applied to the lumbar region;
• a pelvic harness;
• anchor means on said lower body section adapted for connection to said pelvic harness to be worn by a patient;
• extensible cylinder and piston drive means communicating with said lower body section and operable to apply a predetermined pressure to cause a lower-body section to reciprocate to and from between said first and second position;
• timing means communicating with said cylinder and piston means to control the operation of said cylinder and piston means to cyclically apply traction to the lumbar region of a patient when a patient wearing the harness is resting in a face down prone position on the table with said pelvic harness secured to said anchor means and when the patient manually engages the upper body restraint means.

A method of applying traction to the lumbar region of a patient by use of a therapeutic table having a frame to which is secured an upper body support section and a separate lower body support section, the said upper body support section being fixedly secured to the frame and including an upper body restraint spaced remotely from the lower body support section and wherein the lower body support section is moveable with respect to the upper body support section and in which a harness strap is secured to an end of the lower body support section remote from the upper body support section, and wherein the upper body restraint may be released by the patient as the lower body support section moves relative to the upper body support section, comprising the steps of:

• (a) supporting a patient in a face-down prone position with the arms raised above the head and releasably grasping the upper body restraint, providing an extensible cylinder and piston means for automatically sliding the lower-body support section to cyclically apply traction to the patient, providing the upper-body restraint in the form of a pair of spaced hand grip means projecting upwardly from the upper-body support section;
• (b) attaching the harness to the lumbar region of a patient to provide for the application of a traction load through posterior straps which are aligned with the patient's spinal column and through anterior straps to the ILIAC crest of the patient's pelvis, and
• (c) cyclically applying and removing a traction load to the harness,
• (d) timing the duration of the load applying the cycle and the load removing cycle,
• (e) controlling the rate at which the traction load is applied and removed during the load applying and load removing cycles,
• (f) allowing the patient to be free to completely release the spaced hand grip means at any time to completely remove the effect of the traction load at any time during the load applying cycle.

A therapeutic table for use when applying traction to a patient's lumbar region when the patient is supported on the table in a prone position comprising:

• a frame;
• a table top having an upper-body section rigid with respect to said frame and a lower-body section slidably mounted with respect to said frame, said sections providing a separable surface on which a patient may lie in a face-down prone position;
• upper-body restraint means for restraining the patient with respect to the upper-body section, said restraint means including a pair of spaced hand grips which are rigid with respect to the upper-body section and extending upwardly from the plane of the table top to be accessible to a patient when resting upon the table top with the arms extended above the head along the plane of the axis of the patient's spine to provide a releasable anchor for the upper body;
• a pelvic body anchor rigidly mounted with respect to the lower-body section to provide an anchor to which a pelvic belt can be connected;
• extensible pneumatic cylinder and piston means extending between the frame and the lower-body section and operable to move the lower-body section with respect to the upper-body section to increase or decrease the distance between said upper body restraint means and aid pelvic belt anchor to apply traction through the patient's arms to the lumbar region of the spine;
• and
• hydraulic damping means extending between the frame and the lower-body section for damping movement of the lower-body section with respect to the frame to control the rate of movement of the lower-body section with respect to the upper body section;
• means for automatically alternately applying a predetermined pneumatic pressure to said pneumatic cylinder and piston means in a first direction and a second direction opposite to said first direction to cyclically apply traction to a patient in use;
• traction measuring means mounted on said pelvic belt anchor and connectable to a pelvic belt strap for measuring the tension in the strap and thereby determining the traction load applied to the patient;
• means for translating the traction load detected by the traction measuring means into a readable form;
• timing means for controlling the timing of the movement of the lower-body section in each said direction whereby the duration of each traction period and each relaxation period may be independently timed, and said upper-body restraint means being completely releasable by the patient as said lower-body section moves with respect to said upper-body section to thereby permit the patient to limit the amount of traction placed on the lumbar region.
