A chiropractic treatment table and method for treating a patient's spine for providing true longitudinal distraction alone or in combination with vertical flexion and extension, lateral flexion, and/or rotation. The treatment table includes a longitudinally moveable head support portion slidingly mounted on an anti-friction structure whereby the head support portion is freely moveable with practically no frictional or drag. In view of the anti-friction structure, the net longitudinal distraction force is primarily only that which is applied by the chiropractor thereby not requiring adjustment or compensation for drag or other forces, and thereby providing the chiropractor substantially improved control of the actual applied distraction force for administering the desired distraction.
A flexion-traction type lumbar traction table for treating a patient including a base supporting a stationary head-thoracic support and a pivotally movable pelvic support section positioned end-to-end with the head-thoracic support section. Upper and lower pelvic sections form the pelvic support section and are connected together for sliding longitudinal translation of the upper pelvic section on the lower pelvic section. A proximal end of the lower pelvic section is connected for pivotal movement about a horizontal transverse flexion axis between a horizontal first position and a downwardly inclined second position. An axial traction member is pivotally connected between the upper pelvic section adjacent to a distal end thereof and the frame just beneath the flexion axis wherein said upper pelvic section is automatically slidably translated further from said proximal end of the lower pelvic section as the pelvic support section is manually pivoted downwardly for enhanced longitudinal traction.
A spinal treatment apparatus for applying a force to a patient includes a base portion, a telescoping support, a spinal distraction device and an actuator. The telescoping support is mounted on the base portion and includes a bottom member and a top member. The top member is engaged with the bottom member so that the top member has a retracted position and an extended position. The telescoping support is capable of withstanding a force, corresponding to the spinal treatment force, imparted on the top member, while in both the retracted position and the extended position. The spinal distraction device is mounted on the top member and applies the spinal treatment force to the patient. The actuator moves the top member vertically relative to the bottom member.
Devices, systems, and methods for compensate for friction within powered automatic systems, particularly for telesurgery and other telepresence applications. Dynamic friction compensation may comprise applying a continuous load in the direction of movement of a joint, and static friction compensation may comprise applying alternating loads in positive and negative joint actuation directions whenever the joint velocity reading falls within a low velocity range.

A therapeutic table construction which isolates a first portion of the patient's body to a fixed table portion and a second portion of the patient's body to a moveable table portion, and applies a distraction force to the moveable portion of the patient's body while positioning the portion of the patient's spine that is to be treated at an angle so as to isolate the portion of the patient's spine which receives the distraction force.
