Benefits of technology

[0010]Another aspect of the invention relates to a method of increasing knee strength, function, or range of motion in a patient. The method comprises causing the patient to simultaneously apply a knee extension force and one or more forces selected from the group consist...

Problems solved by technology

There are a number of ways in which the normal function of the knee joint may be impaired.
For example, one or both of the anterior and posterior cruciate ligaments that stabilize the knee may be torn or damaged.
Tears in the menisci between the femur and the tibia may cause those bones to grind together.
Years of use may result in wear on the menisci, the articular cart...

Embodiment Construction

[0023]FIG. 1 is a perspective view of a knee-stretching device, generally indicated at 10, according to one embodiment of the invention. FIG. 2 is a side elevational view of the knee-stretching device 10 in use. The knee-stretching device 10 includes a lever portion 12 and a fulcrum portion 14 arranged such that the knee-stretching device 10 acts as a first class lever. As will be described below in more detail, the knee-stretching device 10 allows a patient to stretch his or her own knee.

[0024]The lever portion 10 includes a first end 16 and a second end 18. In the illustrated embodiment, the lever portion 10 is made of a substantially rigid, tubular material, such as aluminum or steel. The first end 16 is capped by a grip 20, which may be plastic or rubber, such that the first end 16 is adapted to be grasped by a user. The second end 18 is also provided with a cap 22, which may also be formed of plastic or rubber.

[0025]The fulcrum portion 14 is located intermediate the first and s...

Abstract

A knee-stretching device and methods of increasing knee range of motion in extension are disclosed. The knee-stretching device allows a patient to self-stretch and acts as a first class lever, applying force supplied by the patient's arms to the knee through the distal portion of the leg. The knee-stretching device can apply traction, varus, and valgus forces in addition knee extension force. Disclosed treatment methods include the use of the knee-stretching device before surgical intervention.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 60 / 758,182, filed on Jan. 10, 2006, the contents of which are incorporated by reference herein in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates generally to the fields of rehabilitation and physical therapy and, more specifically, to rehabilitation devices and methods for the knee.[0004]2. Description of Related Art[0005]The knee joint is one of the more complex and important joints in the human musculoskeletal system. Together, the knees essentially support the entire body weight during most types of upright movement. In particular, knee strength, stability, and range of motion are very important for proper standing, walking, and running.[0006]There are a number of ways in which the normal function of the knee joint may be impaired. For example, one or both of the anterior and posterior cruciate ligaments tha...
