The method further includes rotating the wrist during movement of the wrist away from the elbow. ## Claims ### Claim 1 A method for treating carpal tunnel syndrome in a patient comprising the steps of: providing a stationary supporting surface; securing the forearm to the supporting surface in a generally horizontal position and the upper arm to the supporting surface in a generally vertical direction to restrain the elbow of the patient from movement along the supporting surface in a generally rectilinear direction; providing a drive member: securing the patient's wrist to the drive member: activating said drive member to move the wrist rectilinearly away from the elbow to place said wrist and forearm in traction for a predetermined time period and pressure; deactivating said drive member after said predetermined time period to discontinue said traction; and intermittently repeating said activating and deactivating steps for a duration determined appropriate to treat the patient. ### Claim 2 (depends on 1) The method of claim 1 which further includes the step of rotating the wrist and forearm during movement of the wrist in a direction away from the elbow. ### Claim 3 A method for passively stretching an individual's forearm muscles to relax the individual's carpal ligament and maintaining the muscle stretch for a predetermined time period, comprising the steps of: providing an arm rest having a horizontal upper supporting surface; positioning the individual alongside the arm rest to enable placing a forearm on said upper supporting surface; firmly attaching the individual's forearm to said supporting surface adjacent the elbow to restrain the forearm and elbow against longitudinal movement relative to said arm rest; providing a wrist-encircling harness remote from said elbow in longitudinal alignment with said horizontal supporting surface; firmly attaching said harness at the base of the individual's hand and about the wrist independently of attachment of said forearm to said arm rest; applying a predetermined controllable distracting force to the forearm by moving said harness and arm rest relatively longitudinally away from each other to thereby provide a steady stretching tension between the elbow and wrist harness for a predetermined time period; and, upon completion of said predetermined time period, relaxing the distracting force and repeating the foregoing steps a predetermined number of times. ### Claim 4 (depends on 3) The method of claim 3 wherein the arm rest is stationary, and wherein the distracting force is applied solely to said wrist harness. ### Claim 5 (depends on 4) The method of claim 4 wherein a pair of straps are provided at opposite sides of said wrist harness, and wherein said distracting force is applied by pulling on said straps away from the patient's elbow. ### Claim 6 (depends on 5) The method of claim 5 wherein a rotational force is applied to said straps to apply both torsional and longitudinal stretch to said wrist and forearm during application of said distracting force. ### Claim 7 (depends on 6) The method of claim 6 wherein said longitudinal and torsional stretching are simultaneously applied during application of said distracting force. ### Claim 8 A method for treating carpal tunnel syndrome of a patient comprising the steps of: providing an arm rest having an upper supporting surface; securing a patient's forearm to the supporting surface to restrain the patient's elbow against longitudinal movement relative thereto; providing a harness for the wrist of the secured arm; firmly encircling the wrist with said harness and fastening the harness in place to resist harness rotation relative to the wrist; and, repetitively applying a controllable outwardly-directed rectilinear force for predetermined time periods between the harness and the restrained elbow to longitudinally and softly distract the forearm and wrist thereby reducing compression of the patient's carpal tunnel ligament, and wherein the rectilinear force is gradually increased in subsequent applications of said method. ### Claim 9 (depends on 8) The method of claim 8 including the additional step of applying a rotational force to said harness to apply torsion to said wrist and forearm while being distracted. ### Claim 10 (depends on 9) The method of claim 9 wherein both said forces are applied simultaneously during said distraction. ### Claim 11 (depends on 8) The method of claim 8 wherein said supporting surface is generally horizontal, and wherein said patient is seated at a seat level below said supporting surface to enable the patient to comfortably rest said forearm horizontally on said supporting surface during treatment. ### Claim 12 (depends on 7) The method of claim 7 including providing a pair of longitudinally-directed reins on horizontally-opposed sides of the harness, said reins extending away from the elbow during treatment, and wherein said pulling force is applied essentially through said reins to said harness and therefrom to said wrist and forearm. ### Claim 13 (depends on 12) The method of claim 12 wherein an air pressure operated means is provided to apply said pulling force, and wherein the ends of said reins remote from said harness are offset vertically and secured to said air pressure operated means, said vertical offset effecting a rotational force to said harness about a horizontal axis as said air pressure operated means applies said pulling force through said reins.
