Robotic knee testing device, subjective patient input device and methods 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. An apparatus for evaluating leg movement characteristics of a patient, said patient having a torso, and also having a first leg extending from said torso, said leg including a femur, patella, tibia, and a foot distal relative to said tibia and pivotably attached at an ankle joint relative to said tibia, said apparatus comprising:
A) a base assembly configured to at least partially support said torso; and B) a leg support assembly independently pivotably mounted about a pivot axis relative to said base assembly, said leg support assembly configured to at least partially support a portion of said leg, said support being independent of said support of said torso, said leg support assembly including:
1) a first leg support member comprising a foot rotation assembly rotating about at least one axis of rotation relative to said base assembly, said foot rotation assembly configured to at least partially retain and support a portion of said foot of said patient and to cooperate within said first leg support member so as to rotate said foot portion relative to said base assembly, said axis of rotation of said foot rotation assembly lying in a plane substantially parallel to said pivot axis of said leg support assembly, and said axis of rotation of said foot rotation assembly being distally spaced from the entirety of said foot and in a more distal position than the entirety of said foot, the entirety of said foot being positioned intermediate said pivot axis of said leg support assembly and said plane of said axis of rotation of said foot rotation assembly; and2) a second leg support member configured for supporting a portion of said leg at a location proximal relative to said first leg support member during said rotation of said foot, said foot rotation assembly configured to rotate said associated foot about said axis of rotation such that an associated leg movement is provided and can be measured.
