A shoulder orthosis configured to control a position of the humeral head / arm relative to a shoulder joint by adjusting tension across a joint. The orthosis allows a user to modify a direction and magnitude of force applied while wearing the orthosis. The orthosis may contain cams or extensions to direct and amplify force around the joint towards a specific range of motion. The orthosis can be made from digitally imaging joints and then partially or fully automating the design of orthosis.

An apparatus to facilitate a user to efficiently perform both hamstring curl and hip thrust exercises. The apparatus includes a base platform with three adjustable pads. The user can recline over the pads in a prone position to perform the hamstring curl exercise, with first and third pads inclined to prevent slipping and ensure proper alignment. The apparatus includes at least one lever pad to support the user's ankles, which can be adjusted for optimal positioning and resistance via a weight stack. The third pad is capable of rotating to assist with hip thrust exercises and is connected to a second weight stack for adjustable resistance. Range controllers for the lever pad and the third pad help prevent excessive movement, ensuring safety and allowing users to customize their range of motion. The apparatus includes a belt to secure the torso that rests over the second pad.

An electronic goniometer for measuring the flexibility or range of motion of a subject receives input data comprising point coordinates in a 3D space relating to the anatomical features of the subject

A system and method for performing range of motion measurements in an unsupervised manner. A user equipment with one or more cameras may be used with an application on the UE using the one or more cameras to measure range of motion of a user of the UE. The patient may record movement of the part of the body of interest, such as the head. The movement may be recorded in three dimensions (e.g., calculated from two dimensional coordinates of an image) and processed by the application, and the three rotational angles calculated corresponding to the difference between the final position of the head and the initial position of the head at the beginning of the recording. As a result, facial recognition is used to improve monitoring of range of motion during surgical recovery in an unsupervised environment.

A system and method may use a robotic arm to perform a range of motion test for use in generating information related to kinematic alignment in a total or partial knee arthroplasty. A method may include controlling a robotic arm to move a tibia throughout a range of motion for a knee. A series of measurements of gap distance for the knee may be used to determine a tibial resection location for the tibia. The method may include updating a plan (e.g., 3D, preoperative) for an orthopedic procedure on the knee with the tibial resection location.

A device for increasing the range of motion (ROM) of a patient's afflicted knee joint following total knee arthroplasty (TKA) comprising an apparatus for insertion onto the pedal of an existing recumbent stepper machine. The apparatus enhances the functionality of recumbent steppers by (1) increasing the ROM angle of the knee at every seat position by moving the patient's foot closer to the stepper seat and thus the patient's torso, and by (2) allowing more ankle flection and a deeper guard rail than the original pedal to help maintain heel contact with the apparatus throughout the session.

A method of evaluating a human knee joint including a femur bone, a tibia bone, and ligaments. The method includes: inserting into the joint a tensioner-balancer that includes at least one force sensor; providing an electronic receiving device; moving the knee joint through at least a portion of its range of motion; using the electronic receiving device to collect data from the at least one force sensor; processing the collected force data to produce a digital geometric model of the knee joint, wherein the data includes: a medial spline representing a locus of points of contact of a medial condyle of the femur F with the tensioner-balancer, over a range of knee flexion angles; and a lateral spline representing the locus of points of contact of the femur F with the tensioner-balancer, over a range of knee flexion angles; and storing the digital geometric model for further use.

This application relates to the field of daily necessities, specifically to a lightweight, resilient coupling support strip, which is composed of a support strip body including a lifting section, a flexible section, and a tail section. The flexible section is located in the middle of the support strip body, with the lifting section and tail section located on either side of the flexible section. The flexible section is divided into a bending section and a compression section, both of which have grooves. The grooves in the compression section and the bending section are staggered, with the grooves in the compression section being deeper than those in the bending section. The groove depth gradually decreases towards both sides, centered on the maximum bending position of the knee joint. During bending, the deep and shallow grooves cooperate, and when the knee joint bends to a threshold angle, the groove structure generates resistance feedback, helping the user control a reasonable range of motion and avoid excessive bending injury. The bending pressure difference generated by the force on both sides of the grooves can adjust the fit in real time, achieving dynamic correction during movement. The thickness difference in the lifting section facilitates gripping with fingers and transmitting pulling force during wear, improving wearing efficiency.

Embodiments of the invention provide knee prostheses which more faithfully and closely replicate the function, anatomy and physiology of the normal human knee yielding a number of advantages. Among other things, such prostheses can provide an increased range of motion and function more normally particularly in extension, deep flexion and during normal gait. Knee prostheses according to various aspects of the invention recognize that during movement of the knee, particularly during flexion, the kinematics of the bones of the knee are a result of achieving equilibrium of the forces that cause motion of the knee. In addition, the shape of the articular surfaces acting in combination with forces imposed by various muscles, ligaments and tendons, determines the direction of the large contact forces.

This invention belongs to the field of exoskeleton robotic arms, specifically an exoskeleton robotic arm based on a multi-link mechanism. It includes a shoulder fixation strap with shoulder joints at both ends. An arm structure is located below the shoulder joints. Each shoulder joint includes a actuator assembly and a series linkage mechanism with three rotational degrees of freedom, enabling the arm structure to rotate in three directions. The arm structure includes an upper arm and a forearm, connected by a four-bar linkage, which drives the reciprocating flexion and extension movements of the arm structure. This invention places the actuators at the shoulder joints, resulting in a compact overall structure and low inertia. By designing a multi-link mechanism, the circular motion of the actuators is transformed into flexion and extension movements of the elbow joint, improving the arm's movement speed and transmission efficiency. Furthermore, it maintains a reasonable range of motion for the elbow joint even under arbitrary actuator motion conditions, exhibiting high reliability and safety.
