Abstract:
An exercise device has a bar with attached two arms which press by their free ends with sharp elements against and dig into the ground on the left and right sides of person's body when person is laying on his back and together with rope block and rope with stirrups create support and leverage to lift person's legs and in some cases almost whole body above the ground in the air. Positioning the free ends of the arms in different places along a person's body gives possibility to redistribute tension between person's arms, legs and stomach muscles and creates different intensity of exercises. The numerous stretching and straining exercises can be accomplished by interaction between exercise device and person's legs and hands using body weight. The exercise device has freedom of movement and its arms' ends are not permanently connected to the ground or to anything else. The mobility of the device gives possibility to exercise while laying in bed for partially paralyzed persons to rehabilitate their condition without assistance. A few versions of this device can have capabilities of quick adjustment and to fold the device to a compact size.
Abstract:
A self-assisted shoulder passive range of motion (SA-PROM) apparatus. The apparatus includes a forearm support adapted to receive the forearm of the affected arm, a double pulley assembly, a single pulley connectable to an elevated support such as an upper door edge, and a main support rope, one end of which is attached to the double pulley, the other end having an enlarged handle. A central portion of the main support rope is engagable over the single pulley. A secondary rope arrangement which is preferably formed of a single length of rope, is attached to each of a plurality of holes formed through said forearm support in proximity to each end and each side margin of the forearm support and arranged over the secondary pulleys to self-regulate pitch and roll movement of the forearm support. The affected arm may be passively raised and lowered through a range of motion by pulling on the handle with the unaffected arm.
Abstract:
Therapy and exercise unit (10) for restricted-guidance knee joint motion, having two lower leg receivers (35, 36), which are disposed on a guiding arrangement (11) and connected by articulated devices (23, 24) to a transmission element (28) of the guiding arrangement, which transmission element connects the lower leg receivers to one another in a motionally coupled manner such that a swivelling motion of the one lower leg as a result of bending of the knee initiates an oppositely directed swivelling motion of the other lower leg, wherein, for connection of the lower leg receivers (35, 36) to the articulated devices (23, 24), a lever (34) is provided which produces a restoring moment (Gxh), which in terms of the direction of rotation counteracts a leg extension, about a pivot (45) of the respective articulated device (23, 24).
Abstract:
The apparatus provides active and passive exercise to the hand, wrist and forearm of the patient. It has dual handles and an attached inertia apparatus such that both the affected arm and the non affected arm are subjected to the therapy. It is theorized that in the retraining of nerve, muscle and ligament/tendon function there is cross-training of right-left part of the systems and the healthy system can assist the afflicted part of the system in retraining. The apparatus addresses specifically the range of motion of the wrist, both for flexion-extension and pronation-supination. For pronation-supination, two conical handles, one for each hand is attached through an axis to a gear system connected to a flywheel. The gear/flywheel system allows for clockwise and counterclockwise rotations of the flywheel. The patient puts the system in motion by rotating the handles in either a clockwise or counterclockwise direction. The rotary (oscillating) motion is transferred to the flywheel through the gears. Adjustment of the starting position of the handle allows the patient to establish the starting point as the point where the patient's strength is maximal. The flywheel stores sufficient energy during the starting input of the patient to continue rotation after the patient's strength and range of motion decreases to the point that no further active rotation is produced by the patient. The inertia in the flywheel then continues the rotation of the patient's wrist, and effects a decrease in the tendon overload which normally occurs in normal physical therapy. An alternative embodiment includes a handle attachment for flexion and extension of the wrist with the orientation of the handle effectively at right angles to the flywheel gear drive of the prior embodiment, whereby the wrist is flexed and extended in causing oscillating rotary movement of the flywheel.
Abstract:
A knee and leg orthopedic exercising device is shown for use by a person that is seated in a chair. The device itself is a wide leg rest that may accommodate both legs of the user, although it could be used for one leg at a time. This leg rest has a side profile of an inverted capital T having a vertical shank portion that is supported from a generally perpendicular crown portion. The edge of one end of the crown portion is provided with an elongated roller which is adapted to roll upon a floor surface. The top side of the side of the crown portion which is remote from the roller serves as a footrest, while the side of the shank portion of the leg rest which is remote from the roller serves to support the shank of at least one of the legs of the user. This leg rest is provided with holding straps for holding the shank portion of the leg rest against the underside of the shank portion of the user's leg as the user flexes the leg between a vertical and an inclined, outstretched position. Two modifications of these holding straps are shown. One modification includes a pair of hand straps to be engaged by the user's hands for exerting a pulling force and ensuring that the crown portion of the leg rest remains against the foot or feet of the user. A second modification of holding straps is the use of a pair of leg straps which are wound around the user's legs and around the shank portion of the leg rest to bind the leg to the leg rest so that they move in unison.

Each means (2) is connected with a means (4) for the measurement of forces (F). The device of the invention further includes an accelerometer (5), a gyroscope (6) and a magnetometer (7) for the determination of its position and orientation in space, wherein all data from said means (4), said accelerometer (5), said gyroscope (6) and magnetometer (7) are gathered by said microcontroller (8) that evaluates them with models and algorithms, and said data are continuously displayed on a display (9), a monitor or a TV screen, notifying the exercising person on the exercising status and suggesting next steps.
