An orthopedic knee brace provides an apparatus for accurately prescribing the anatomical motion of the human knee. The orthopedic knee brace is used for treatment and rehabilitation following surgery to the knee, protection for a surgically repaired knee, and protection for an uninjured knee, among other applications. The orthopedic knee brace actively prescribes asymmetric three-dimensional anatomic motion in six degrees of freedom of the wearer's knee. The rigid connections between the thigh and calf engaging members and the medial and lateral hinges provide the ability of the orthopedic knee brace to prescribe asymmetric three-dimensional anatomic motion in six degrees of freedom by actively prescribing flexion and extension, abduction and adduction, internal/external rotation, anterior/posterior translation, medial/lateral translation, and proximal/distal translation between a femur and a tibia of a wearer's leg. In alternate embodiments a single-hinge brace design is provided for treatment and prevention of osteoarthritis and other joint diseases and conditions.

Therapeutic abduction of the shoulder joint is achieved using a hinged device, the hinge activated by a cable passed between pulleys to increase mechanical advantage. The cable is wound on a spool mounted on a ratcheting mechanism, whereby tension is maintained as the spool is wound via a knob or computer controlled motor. A rotation control device enables rotation of the spool by a user, but prevents rotation due to a load. Mating shackles pivot in connection with the hinge, and are activated by the cable to increase the angle of the hinge. The hinge is connected to the body, one portion affixed relative to the body, the other affixed relative to the upper arm. As the hinge angle is expanded, the shoulder joint is abducted, stretching the tissue of the joint. If resilient, the cable imparts a dynamic tensioning force to the shoulder joint. Medial or lateral rotation is accomplished by a second device disposed at the elbow, wherein the pivot point of internal/external rotation is along the axis of the upper arm.

An automated therapy table is disclosed. The automated therapy table may have various support portions capable of independent automatic actuation of a person's lower extremities through passive exercise. The automated therapy table allows a patient to perform leg elevation, approximation/decompression of the leg, internal/external rotation of the leg, ankle plantar flexion/dorsiflexion, and foot inversion/eversion movements. During each movement, the patient may be instructed to think in the direction of the movement. It has been found that doing so helps increase the healing effects. The disclosed table and method may be beneficial for patients after certain operations as well as for those suffering from various forms of debilitating illnesses, such as Multiple Sclerosis, Charcot-Marie-Tooth, and Muscular Dystrophy.

An asynchronous on-line calibration method for multi-sensor fusion is disclosed. The mutual conversion relationship between the coordinate systems of the three sensors are calibrated, and the measurement information of the plurality of sensors is unified into the same coordinate system, The traditional calibration method is limited to the calibration between two sensors, and requires strict time synchronization, so the calibration process is more complex. The invention calculates the motion of the laser radar, the camera and the inertial measurement unit (IMU) respectively, obtains the motionof different sensors in the same time interval by using linear interpolation, and finally obtains the external rotation between two sensors by aligning the rotation sequence of the three sensors. Theinvention can obtain more accurate external orientation between the lidar, the camera and the inertial measurement unit (IMU), and provides initial value for subsequent calibration.

The invention is an ankle derotation and subtalar stabilization system that incorporates a pivoting adjustable-tension oblique tether strap that is anchored to both a forefoot component and leg component, and that is contiguous with pivoting adjustable-tension derotation strap that passes behind the leg and that is secured to a leg component. The system restrains oppositely directed rotation between the foot and the leg, and can actually after the normal biochemical relationship in a manner that produces foot rotation in a direction opposite to that which is normally coupled with leg rotation, without restriction of upward and downward foot movement. The primary application for the system is restraint of excessive subtalar joint inversion, leg external rotation, and anterolateral rotary displacement of the talus, but it can also be configured to restrain subtalar eversion and leg internal rotation through its incorporation into the structure of an ankle orthosis or shoe.

A knee prosthesis has a femoral component with a medial condyle defining a constant bearing spacing relative to a central sagittal component plane SP, and a lateral condyle defining divergent bearing spacing from the central sagittal component plane along an extension-to-flexion path. High congruence between the medial articulation surfaces creates a pivot point for external rotation at the medial contact area, while lower congruence in the lateral articulation surfaces allows the lateral femoral condyle to track anteriorly and posteriorly during flexion. The amount of lateral condyle bearing spacing divergence is calculated to produce a substantially linear anteroposterior motion profile of the lateral femoral condyle upon the lateral tibia articular surface throughout a wide range of flexion.
