Abstract: 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.

Abstract: A knee examination method includes situating a patient on a patient support adjacent a robotic knee testing apparatus, the apparatus having a motion tracking system. The robotic knee testing apparatus is set up including defining a world coordinate system based on a fixed location of a transmitter of the motion tracking system. The patient is set up including determining one or more local coordinate systems each based on setting up the patient and on one or more robot based points. The robotic knee testing apparatus is operable to manipulate a leg of the patient.

Abstract: Embodiments of the invention are directed to devices for manipulating a hand of a user to provide pronation or supination assistance. Embodiments include an anchor; a hand engagement member operatively attached to the anchor and configured to receive and engage the hand of the user; a force applicator comprising a member portion and an anchor portion opposite the member portion, the force applicator attached to the hand engagement member proximate its member portion and attached to the anchor proximate its anchor portion; and a force application mechanism attached to the anchor and configured to cause a force to be applied to the force applicator causing the hand engagement member to manipulate the hand of the user to provide pronation or supination assistance. In some embodiments, the force application mechanism includes a non-incremental rotary mechanism. In some embodiments, a flexible tethering member attaches the anchor to the hand engagement member.

Abstract: A method comprises obtaining rotational data and translational data for a joint. The rotational and translational data is indicative of rotational and translational movement of the joint during rotational and translational joint testing, respectively. The rotational and translational joint testing is implemented by a robotic testing apparatus. Respective zero torque points are determined for the rotational and translational movement based on the rotational data and the translational data. The respective zero torque points are combined for the rotational and translational movement to determine an equilibrium position for the joint. A biomechanical characteristic of the joint is ascertained based on an analysis of the equilibrium position.

Abstract: A method includes obtaining rotational data and translational data for a joint, the rotational and translational data being indicative of rotational and translational movement of the joint during rotational and translational joint testing, respectively, the rotational and translational joint testing being implemented by a robotic testing apparatus applied to the joint. A quantity indicative of joint play of the joint is computed. The quantity is computed via a function of the rotational data and the translational data. The method includes determining whether the computed quantity exceeds a joint play threshold and, if the computed quantity exceeds the joint play threshold, comparing the rotational data and the translational data with preset rotational data and preset translational data for the rotational and translation joint testing, respectively.

Abstract: The present invention provides an improved portable electronic device mounting system for secure mounting of a camera or any other suitable portable electronic device. Generally described, the present invention includes a mounting system including a base mount, a device mount to which the device can be attached, and a tether. The mounting system is designed such that the device can be detached from the base, while being connected to the mount through a tether when sufficient force is applied. This precludes the potential loss of the device or possible harm to the user during any physical activity.

Abstract: Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance about a joint of a user. In some cases, a device may manipulate an arm of a user, thereby providing extension or flexion assistance to the arm about an elbow. In other cases, a device may manipulate a hand of a user to provide palmar flexion or dorsiflexion assistance about a wrist of the user.
