20140358042 | Pronation and/or Dorsiflexion of First Joint For Evaluation of Second Joint - A method and apparatus for reliably positioning a 3-segment limb, such as a leg or arm for imaging and medical analysis, which can accommodate for the patient's “natural alignment”. The apparatus positions the limb in such a way that the position of the proximal segment is controlled while an known external torque is applied at a known rate to the distal segment. The location of each of the limb's three segments is recorded using either external or internal measurement techniques, and the relative motions between the proximal and intermediate segments are used in the orthopedic evaluation of the proximal joint. Furthermore, the relative motions between the intermediate and distal segments are used in the orthopedic evaluation of the distal joint. By applying a known torque at a known rate, clinicians will be provided with valuable information related to joint range of motion, stability, laxity, and compliance. | 12-04-2014 |
20140276250 | DEVICE WITH THERAPEUTIC FEATURES - Disclosed is a therapeutic stretching apparatus, which in particular provides a user with a system for providing an assist to increase knee extension as well as for maintaining stability of the knee after surgery. This device can not only act as a therapeutic stretching apparatus but also can act as a primary post-op knee brace with locks/limits on hinge to prevent user from further injuring the joint. | 09-18-2014 |
20140081181 | ROBOTIC KNEE TESTING (RKT) DEVICE HAVING DECOUPLED DRIVE CAPABILITY AND SYSTEMS AND METHODS PROVIDING THE SAME - Various limb manipulation and evaluation devices are provided. The devices generally include three drives, namely a first drive configured to manipulate a first bone relative to a second bone in a first direction, a second drive configured to manipulate the first bone relative to the second bone in a second direction, a third drive configured to manipulate the first bone relative to the second bone in a second direction. The three directions are different relative to each other and in some embodiments represent three distinct axes. The devices are further configured such that at least one of the drives is mutually decoupled relative to at least one other drive, such that operation of the one drive does not affect the position or movement of the another drive. One or multiple of the drives may be decoupled. A corresponding method of operating such decoupled drives is also provided. | 03-20-2014 |
20130053735 | UNSTRUCTURED AND STRUCTURED LIMB MANIPULATION APPARATUSES AND METHODS FOR USING THE SAME - Various embodiments provide assemblies for manipulating a user's limb with at least one inflatable member. The assemblies comprise a first pliable planar member and a second pliable planar member overlaid atop at least a portion of the first pliable planar member, such that a two ply configuration is provided. The two ply configuration itself comprises at least a distal and a proximal portion and at least one opening configured to accept at least a portion of the user's limb. The first and second pliable planar members combine to define at least one inflatable member, the inflatable member being at least a portion of at least one of the distal and proximal portions, the inflatable member being configured to be selectively inflatable so as to provide at least one inflation force upon the user's limb, such that the joint in the user's limb is manipulated. Associated methods are also provided. | 02-28-2013 |
20120046540 | Robotic Knee Testing Device, Subjective Patient Input Device and Methods for Using Same - 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. | 02-23-2012 |
