A forearm exercising device having a support frame and a grip secured to one end of a shaft rotatably secured in said support frame and a crank arm secured on the opposite end of said shaft. A cylinder such as a shock absorber operably secured to the shaft controls the rate of movement of the shaft and the grip or crank arm to which the user applies his arm regardless of the force exerted thereon. An upper arm support and restraint member is adjustably secured to align the medial axis of the forearm with the axis of rotation of the shaft which the user is gripping such that movement is controlled as the user moves his hand through supination and pronation. A forearm support platform is secured such that the hand and wrist extend beyond the edge of the platform when gripping the crank arm to restrain forearm movement as the hand moves through palmarflexion and dorsiflexion in moving the crank arm at a controlled rate of speed.
A device for handgripping or squeezing, forearm twisting, wrist casting, wrist rocking and a combination of some of these. A handle mechanism is rotatably mounted on a frame. This mechanism includes a fixed handle and a movable handle, movement of the last mentioned handle being resisted by a force which may be varied. One may grasp the two handles simultaneously and exert the fingers so as to move the movable handle towards the fixed handle in opposition to the applied force. Rotation of the handle mechanism is provided with torsional resistance which may be varied. One may grasp the fixed handle with the arm in alignment with the axis of the device and rotate the handle mechanism in either direction or one may grasp the fixed handle with the arm disposed at right angles to the position previously described and rotate the handle mechanism in either direction. A third handle may be provided which is disposed at right angles to the fixed handle, in alignment with the axis of the device and which may be grasped by the user so as again to rock the handle mechanism in either direction. Squeezing resistance may be effected through a cable attached to the movable handle and to an extension spring. Torsional resistance may be effected between a rotatable friction disk and a slidable, but not rotatable, friction disk which may be forced against the rotatable friction disk by a force which may be varied.
A machine for exercising the rotator cuff of a user includes an upright support frame having a front, a top, first and second sides defining a plane of the upright support frame, and a support structure extending from the front adjacent the top of the upright support frame. The machine preferably includes a forearm support assembly for supporting a forearm of the user in a plane substantially transverse to the plane of the upright support frame, wherein the transverse plane also passes through the shoulders of the user such that the user's arm is positioned substantially in the transverse plane to isolate the user's rotator cuff. A tension mechanism is mounted on the upright support frame and includes a tensioned cable. A cam mechanism is connected to the tensioned cable and supported by the support structure of the upright support frame for rotation with the forearm support assembly under tension as the user's forearm is rotated.
The present invention provides an isokinetic ergometer comprising a movement guide, power gripping points, a brake unit connected therewith and a speed regulator, characterized by the following features: (a) the power gripping points are mechanically connected with a piston movable in a cylinder, (b) a flow regulation valve is attached to the cylinder, and (c) the cylinder and flow regulation valve are hydraulically connected with one another via a pipe, the flow regulation valve regulating the length of the stroke.
A shoulder exercising apparatus (100) is adapted for use by a patient to exercise selected muscle/skeletal groups in the shoulder regions. The apparatus (100) includes a rectangular bracket (102) having an adjustably mounted saddle assembly (108). An exercise bar assembly (116) is pivotably coupled to the bracket (102) and includes an elongated outer tube (122) with a power slide (128) having a friction mounting on the tube (122). In use, a patient (136) secures his or her arm within the saddle assembly (108) and moves the power slide (128) along the outer tube (122), thereby exercising various muscles in the shoulder region in accordance with the patient's position relative to the exercising apparatus (100). A force measuring mechanism (124) is coupled to the tube (122) so as to measure external forces exerted in moving the tube (122) relative to a handle rod (138) connected to the bracket (102) and partially received within the tube (122).
The present invention comprises a portable exercise device comprising a mechanism for resisting longitudinal displacement of a user's hands, as well as a mechanism for resisting longitudinal displacement of a user's elbows. The device has two handles, with each of the handles being joined to the hand displacement resisting mechanism. The device further comprises two elbow pads, with each of the elbow pads being joined to the elbow displacement resisting mechanism. A user's forearms are laterally positioned between each handle and each elbow pad.
