ROBOTIC KNEE TESTING DEVICE, SUBJECTIVE PATIENT INPUT DEVICE AND METHOD FOR USING SAME

摘要

An apparatus for evaluating leg movement characteristics of a patient is provided. The apparatus comprises a base assembly configured to at least partially support the patient's torso; and first and second leg support assemblies independently pivotably mounted about a pivot axis relative to the base assembly. Each leg support assembly is configured to at least partially support a portion of a respective one of the first and second legs, independent of the support of the torso. Each of the leg support assemblies also comprises: a first leg support member including a foot rotation assembly configured to at least partially retain and support an associated foot of the patient and to rotate it about an axis of rotation relative to the base assembly; and a second leg support member configured for supporting a portion of the leg at a location proximal relative to the first leg support member.

主权项

1. A method for evaluating relative bone movement characteristics of a patient, said patient having at least three interconnected bones, a first bone connected to a second, “free positioned” bone, and a third bone connected to said second bone, said method comprising the steps of:
A) fixing said first bone relative to a frame; B) attaching a force application system to said third bone; C) moving said third bone with said force application system such that said second, “free positioned” bone moves relative to said frame; and D) measuring movement of said second, “free positioned” bone relative to said base via external measuring.
