Abstract

An exercising device for use in strengthening, conditioning and rehabilitating body joints such as the knee and shoulder. The device is used in connection with conventional exercising apparatus to minimize detrimental shearing forces on the joint during the exercise procedures. This is accomplished by replacing the conventional single contact pad on the limb with two contact pads or pad and handgrip mounted on a variable fulcrum that will produce the desired counterforce to the shearing force on the joint.

Claims

1. An exercise device for use in connection with a body joint and limb exercising apparatus which has a movable member to which the apparatus applies a force against movement of the member, said exercise device comprising an elongated member having a distal end and a proximal end, first limb engaging means connected to said elongated member at a point near the distal end of said elongated member and engageable with a limb of a user, second limb engaging means connected to said elongated member at one of a plurality of selected points near the proximal end of said elongated member, said second engaging means being attached to the same limb of a user at a point on the limb spaced from the point of engagement of the first limb engaging means, third means associated with said first and second limb engaging means providing for a releasable attachment of the first and second limb engaging means to the same limb of a user, and connection means along said elongated member providing for varying points of attachment of the movable member to said elongated member at a selected point between the points of attachment of said first and second limb engaging means means with the limb of the user.

2. The exercise device of claim 1 in which said connection means includes means providing for varying the point of connection of the elongated member to the movable member of the exercising apparatus.

3. The exercise device of claim 2 in which said connection means includes means providing for pivotal movement of the elongated member about an axis transverse to the elongated member.

4. The exercise device of claim 3 in which the first and second limb engaging means means are pivotally connected to the elongated member.

5. The exercise device of claim 3 in which the first and second limb engaging means means are separate members and are each pivotally connected to said elongated member.

6. The exercise device of claim 5 in which means is provided for varying the point of connection of the second limb engaging means to the elongated member.

7. The exercise device of claim 5 in which means is provided for varying the point of connection of the first limb engaging means to the elongated member.

8. The exercise device of claims 1, 2, 3, 4 or 5 in which the second limb engaging means and the first limb engaging means are each adapted for releasable engagement with the leg of a user.

9. The exercise device of claims 1, 2, 3, or 4 in which the second limb engaging means is adapted for releasable engagement with the arm of a user and the second limb engaging means is adapted for gripping by the hand of a user.
