Embodiment Construction

[0028] When it is desired to evaluate the 3D kinematics of the human knee, there are difficulties in that the 3D movements of the knee are affected by the movement of the leg during squatting. A ruptured ligament will also affect this kinematics. With a view to evaluate the impacts of various pathologies and of various treatments therefor on the kinematics of the knee, this kinematics must be evaluated during a reproducible movement of the knee and with a load being applied on the knee.

[0029] A gesture-guiding apparatus has thus been developed, wherein the trunk (torso) and feet of the patient are adequately stabilized thereby, to allow a patient to exert a reproducible movement, optionally against an adjustable resistance, in view of establishing a standardized evaluation of the 3D kinematics of the knee. The present guiding apparatus, used in combination with an appropriate kinematics sensing and monitoring device and system, could be for instance used to evaluate the kinematical...

Abstract

A system and method for evaluating the tridimensional kinematics of the knee is presented wherein the system comprises a gesture-guiding apparatus designed to guide a patient through a repeatable, consistent and standardized motion in view of evaluating the condition of the patient's knees. A hack squatting motion, which generally involves a substantially linear vertical squatting motion of the body, is used to isolate the leg and knee movements and increase repeatability. The patient's upper body is generally stabilized and optionally constrained such that a standardized orientation and alignment thereof is maintained throughout the motion. The patient's feet may also be stabilized and constrained. Motion resistance settings may be provided using a set of adjustable weights and counterweights to accommodate various patients and patient conditions.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a method and apparatus for the standardized evaluation of body kinematics. More specifically, the present invention is concerned with a method and apparatus for the standardized evaluation of the three-dimensional kinematics of the knee. BACKGROUND OF THE INVENTION [0002] Knee pain and injuries are quite common in athletes and sports enthusiasts of all types. In particular, knee ligament strains and tears can often result from strenuous activity, vigorous sports, and other such physical situations wherein the knee, whether healthy or generally prone to injury, is required to move against a restrictive force or weight. As a result, evaluation practices and methods have been developed to study and monitor the movement of the knee to evaluate the dynamics and kinematics thereof. [0003] For instance, U.S. Patent Publication No. 2003 / 0018283 for a “Feedback Estimation of Joint Forces and Joint Moments” by Dariush and publishe...
