Abstract: A deep tendon reflex-eliciting device actuated by pressure against a patient's skin, which releases a spring-loaded mass that delivers an impulse through a fully-enclosed housing. This device includes a weight contained within the casings, and a mainspring in communication with the weight. The mainspring has a bias toward expansion. In the compressed position, the mainspring is also compressed, and the weight is pushed backwards into the rear casing. The weight is released to be driven forward by the mainspring. The weight strikes the inside of the forward casing, delivering an impulse to a surface against which the device is pressed. A reset spring can push apart the forward and rear casings to reset the device to its expanded position. A case screw is also included which is able to consistently set the impact force of the device.

The left and right side defined at the front and rear of the upper support plate are respectively provided with a pair of the slide seats connected through the slide rail, thereby allowing each of the slide seats to slide towards left and right at the corresponding edge of the upper support plate. The front and rear of the pair of the slide rails are respectively provided with a pair of the support cushions, thereby allowing each of the support cushions to forwardly and backwardly slide on the corresponding slide rail; because the frame for spine surgery is made of a non-metal material, no interference of metal component is generated when spine fluoroscopy is processed.

Abstract: The invention provides a lumbago treatment instrument which manipulates the pelvis safely and properly by pressing the coccyx utilizing the patient's own body weight. A coccyx contact treatment member is disposed inside a cylindrical casing so as to be movable in the vertical direction via an elastic member. A coccyx contact buffering member made of sponge or the like is provided on the upper end of the coccyx contact treatment member. The patient straddles the coccyx contacting buffering member, assuming a sitting posture, and places the coccyx on the coccyx contact buffering member. In this posture, both feet are slightly lifted from the floor to apply the body weight on the coccyx contact buffering member so that the coccyx is pushed up from below. When doing so, the patient continues to maintain an upright posture while pressing the upper body against a posture holding member and gripping a handle with both hands.

At this time, the recipient maintains an erect posture while pressing his/her upper body against a posture holding member (2) and gripping a handle with his/her both hands.

Abstract: The physical therapy tools, systems, kits and methods described herein may be used to apply gentle, passive and progressive amounts of pressure (including numerous repetitions of small movements) to achieve therapeutic mobilization of a spinal joint. The tools described herein may include a plurality of pads and actuators, where the pressure within each actuator is controlled so that a continuously varying pressure may be applied to mimic the pressure applied by human hands. These tools may also include a controller and one or more user inputs. The physical therapy tools may be operated at different operating modes (e.g., continuously varying pressure modes, step-pulse high frequency modes, step-pulse low frequency modes) for treating a subject's spine, and may be part of a system or kit. Methods of treating a subject using these physical therapy tools are also described herein.

Abstract: A power operated chiropractic adjuster is disclosed. It uses a driving set to rotate an urging ring, which drives a pulling ring to perform a reciprocal motion along its axial direction. It has an impact set that includes a control pin, a plunger, and an escape tube connected with the pulling ring to perform a reciprocal motion with the pulling ring. The rear section of the firing ring has a second spring. The escape tube is mounted on the plunger and constrains it. The control pin is disposed inside the plunger and can release the constraint between the plunger and the escape tube. The plunger is driven by a restoring elastic force of the second spring to perform a firing action. The power operated chiropractic adjuster also has an urging pin set whose one end is disposed opposite to the impact set and whose other end is opposite to a hammer set. When the plunger fires, the urging pin set is hit by the plunger to push the hammer set, producing an ejection effect.

Abstract: A patient suffering from a condition of spinal muscle imbalance is treated by the application of controlled impact forces applied at specific points to the patient's neck. The point of application is to one side or the other of the spine at the rear of the patient's neck. The side to which the impact forces are applied is determined by areas of the body at which prior trauma has occurred that created the condition of spinal muscle imbalance. The forces are applied against the rear of the patient's neck directly below the head and at a force application point immediately at the splenius muscle and between the attachment of the superior border of the trapezius and the sternocleido mastoideus muscles to the patient's head. the impact forces are of a selected magnitude of between about four ounces and five pounds and are applied at a rising angle of about twenty five degrees toward the eye socket-temple area of the opposite side of the patient's head.

Abstract: An improved chiropractic adjusting instrument and method is provided for use in spinal manipulative therapy and for exciting a human spine at its natural frequency. The chiropractic adjusting instrument includes a thrust element for delivering an input force, a body contact member removably attached to the thrust element, a spring member for propelling the thrust element and the body contact member outwardly, and an adjustment knob arranged on the thrust element for adjusting the amount of potential energy imposed on the spring member and for controlling the magnitude of the resulting input force. In use, the input force is mechanically tuned to the natural frequency of a musculoskeletal structure (e.g., a human spine) by positioning a shaped mass on the thrust element, by varying the stiffness of the removable body contact member, and/or by varying the stiffness of the spring member. The input force is then delivered to the musculoskeletal structure at its natural frequency.

The latch assembly is operably interconnected to the central handle and carries and holds the anvil member in the retracted, cocked position upon movement of the central handle towards a palm handle on an opposite end of the housing.

Abstract: An improved chiropractic adjusting instrument is provided for use in spinal manipulative therapy and for exciting a human spine at its natural frequency. The chiropractic adjusting instrument includes a thrust element for delivering an input force, a body contact member removably attached to the thrust element, a spring means for propelling the thrust element and the body contact member outwardly, and an adjustment knob arranged on the thrust element for adjusting the amount of potential energy imposed on the spring means and for controlling the magnitude of the resulting input force. In use, the input force is mechanically tuned to a desired frequency (e.g., the natural frequency of a human spine) by positioning a shaped mass on the thrust element. By mechanically tuning the chiropractic adjusting instrument in this way, the dynamic output response of the spine is maximized while the requisite impact force is minimized.

Abstract: An apparatus for self administration of acupressure that comprises a surface for supporting the individual. A pressure arm supported above the surface moves between a first position displaced from the individual and a second position where pressure probes apply acupressure. The position of an actuation arm supported below the surface is controlled by the individual and is linked to the pressure arm. This enables the individual to control the magnitude and duration of force applied through the pressure arm and pressure probes. The individual can operate another linkage to position the pressure probes relative to the pressure arm and along the individuals' spine.
