Abstract:
The present invention is to provide a vertical auxiliary apparatus for both body inversion and rehabilitation, which includes a base positioned on the ground and having first and second pivotal connecting portions at positions adjacent to one end thereof, a motor pivotally connected to the first pivotal connecting portion, a telescoping rod having a first end movably connected to the motor, a supporting frame pivotally connected to the second pivotal connecting portion at a position adjacent to a first end thereof and a second end of the telescoping rod at a position adjacent to a second end thereof respectively, and a foot frame fastened to one end of the supporting frame. Thus, when the motor is activated, the second end of the telescoping rod drives the supporting frame to rotate about a fulcrum defined by the second pivotal connecting portion and change the tilt angle relative to the ground.
Abstract:
A passive exercise therapy station moves a patient's limb or body part through a prescribed range of motion without stress to the patient's limb or associated joints. A frame is formed of a pair of arches joined in parallel to one another, with a pair of overhead horizontal rails. One or more main cables extend over guide pulleys on the frame and past an adjustable guide carriage that travels along the overhead rails. An actuator positions the guide carriage at a desired location on the overhead rails. An exercise cable descends from the guide carriage to the patient. The exercise cable may be a web attached to the main cable. The exercise therapy station may be wheeled between rooms for therapy of a given patient.
Abstract:
A chiropractic evaluation, diagnostic and adjusting system includes a surface having including an elongated slot therein, a number of actuators, each including a rod and a position sensor, and a drive for translating the adjustment actuators along the length the slot. A control system determines a curvature of a spine of a patient by controlled extension and retraction of each rod into and out-of contact with the spine of the patient via the slot during translation of the adjustment actuators along the length of the slot. The control system compares the determined curvature of the spine of the patient to a predetermined spine curvature and controls the drive and each of one or more of the actuators to apply a series of corrective stroke pulses to an area of the patient's spine requiring adjustment via the rod of the actuator.
Abstract:
A lower limb orthotic device includes a thigh link connected to a hip link through a hip joint, a hip torque generator including a hip actuator and a first mechanical transmission mechanism interposed between the thigh link and the hip link, a shank link connected to the thigh link through a knee joint, a knee torque generator including a knee actuator and a second mechanical transmission mechanism interposed between the thigh link and the shank link, and a controller, such as for a common motor and pump connected to the hip and knee torque generators, for regulating relative positions of the various components in order to power a user through a natural walking motion, with the first and second mechanical transmission mechanisms aiding in evening out torque over the ranges of motion, while also increasing the range of motion where the torque generators can produce a non-zero torque.
Abstract:
A method for controlling movement using an active powered device including an actuator, joint position sensor, muscle stress sensor, and control system. The device provides primarily muscle support although it is capable of additionally providing joint support (hence the name “active muscle assistance device”). The device is designed for operation in several modes to provide either assistance or resistance to a muscle for the purpose of enhancing mobility, preventing injury, or building muscle strength. The device is designed to operate autonomously or coupled with other like device(s) to provide simultaneous assistance or resistance to multiple muscles.
Abstract:
The present invention relates to an electric massage device capable of gradually increasing a massage force during an outward stroke, mainly comprising a massage module and a control module. In the outward stroke, the control module applies a driving current to the electromagnetic driving unit, and the driving current is gradually increased with an elapsed time or a stroke displacement of the output shaft. In a return stroke, the control module deenergizes the driving current or applies a weak reverse current less than one-fifth of the driving current. At the beginning of the outward stroke, the massage force is weak due to the smaller driving current and hence would not cause skin hurt. At the end of the outward stroke, the massage force is strong due to the greater driving current and hence produces a deep muscle massage effect.
Abstract:
The present invention belongs to the technical field of massage and provides an electromagnetic percussion massager employing arc motion, comprising a bent tube, electromagnetic coils, a circuit control module, a magnetic portion and force transmission assemblies, wherein the electromagnetic coils are arranged outside the bent tube and electrically connected with the circuit control module, the magnetic portion is movably arranged inside the bent tube and comprises magnets, the magnets are linearly arranged inside the bent tube, adjacent magnets are attached together through magnetic attraction or flexible pieces, and when the adjacent magnets are attached to each other through magnetic attraction, at least one of the magnets is provided with circular arc or spherical end faces. Compared with the prior art, the present invention can effectively transmit strokes and is applicable for massage of different body parts at different angles, thereby achieving an improved massage effect.
Abstract:
The present invention is an apparatus and method for use in a treatment for prevention of arthrofibrosis that includes a first and a second substantially L-shaped frames, each L-shaped frame having a first member and a second member extending from the first member in a substantially perpendicular direction and terminating in a first end, a fixed plate extending between the first members of the L-shaped frames, the fixed plate being parallel with the first members of the L-shaped frames, a movable plate pivotally coupled to the first ends of the first members of the L-shaped frames with, a pneumatic piston coupled to the movable plate and the fixed plate, a hand operated valve operatively coupled to the pneumatic piston and a goniometer coupled to the movable plate and one of the L-shaped frames, the goniometer adapted and configured to indicate the angle between the movable plate and the fixed plate.
Abstract:
A method of controlling a drive motor for a powered ankle exoskeleton is disclosed. The method includes modeling motor drive current as a linear function of desired torque and ankle angular velocity, and then controlling motor current as a function of measured torque and determined ankle angular velocity.
