Hack squat gestural guiding apparatus in view of a standardized evaluation of the tridimensional kinematics of the knee
First Claim
1. A method for monitoring at least one knee of a patient executing a controlled leg pushing motion applied through his feet in view of monitoring a condition of the knee, the method comprising the steps of:
- a) providing a gesture-guiding apparatus and a monitoring device configured to monitor the at least one knee while the patient executes the controlled pushing motion using said gesture-guiding apparatus, said apparatus comprising a foot-bearing surface for positioning the feet of the patient thereon, a body alignment structure for providing an upper-body alignment of the patient thereon and a guiding mechanism for guiding a substantially linear displacement of said alignment structure relative to said surface through the pushing motion;
b) positioning the patient in said gesture-guiding apparatus according to a pre-selected position;
c) having the patient execute the motion; and
d) monitoring the at least one knee using said monitoring device as the patient executes the motion.

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.

- 12. A gesture-guiding apparatus for controlling a leg pushing motion of a patient in view of monitoring a condition of at least one knee of the patient, the apparatus comprising a foot-bearing surface, an upper-body support structure comprising at least one body alignment mechanism for providing an upper-body alignment of the patient thereon, a guiding mechanism for guiding a substantially linear displacement of said support relative to said surface through the leg pushing motion and a resistance mechanism for adjusting a resistance to the motion, said resistance comprising a weight resistance and said resistance mechanism comprising at least one counterweight to reduce said weight resistance.
- 21. A system for monitoring at least one knee of a patient executing a controlled leg pushing motion applied through his feet in view of monitoring a condition of the knee, the system comprising a gesture-guiding apparatus and a monitoring device configured to monitor the at least one knee while the patient executes the controlled leg pushing motion using said gesture-guiding apparatus, said gesture-guiding apparatus comprising a foot-bearing surface for positioning the feet of the patient thereon, a body alignment structure for providing an upper-body alignment of the patient thereon and a guiding mechanism for guiding a substantially linear displacement of said alignment structure relative to said surface through said pushing motion.

32. A method for monitoring at least one knee of a patient executing a controlled leg pushing motion applied through his feet in view of monitoring a condition of the knee, the method comprising the steps of:
-
a) positioning the patient in a gesture-guiding apparatus and with a selected position for an upper body of the patient;
b) having the patient execute the motion, wherein the upper body displaces substantially linearly; and
c) monitoring the at least one knee as the patient executes the motion.
