A lower extremity mobilizer for use in rehabilitation is provided. A seat is slidably maintained upon a base, with a foot support brace being provided at an end of the base to receive the foot of a leg provided for arthrokinematic treatment. A cord and pulley system is provided between the seat and the end of the base. In use, a patient is seated with a foot received by the foot support brace. The patient provides arthrokinematic motion to his leg by pulling himself and the seat toward the end of the device having the foot support brace. The procedure is undertaken in a closed chain motion, with the foot constantly engaging the foot support brace, and is done so as a rate, timing and extent under the control of the patient.

An orthosis for increasing range of motion of a body joint. The orthosis includes a rotational linkage mechanism having a driving link and a driven link configured for rotation about a joint axis. The driven link is selectively attachable to a body part to rotate the body part about the joint axis. A dynamic force mechanism is operatively connected between the driving link and driven link to impart a dynamic force upon the driven link when the driving link rotates relative to the driven link and the driven link resists rotation with the driving link due to a resistance force imparted on the driven link by the body part reaching a maximum range of motion. The dynamic force is transferred through the driven link to the body part.

A knee extender device includes a central connecting portion, and a first support leg and a second support leg that each extend downwardly from the central connecting portion and that are positioned at an angle relative to each other. A terminal portion is attached to each support leg, with each terminal portion configured to be positioned against an upper leg or a lower leg of an individual. In use, as part of a method of rehabilitating a knee joint of an individual, the device is applied to a leg of the individual adjacent to and over the knee joint, and a cord or belt is extended over at least part of the central connecting portion and around a foot of the individual. Upon applying tension to the cord or belt, the knee extender device is then pushed downward to thereby extend the knee of the individual.

According to one embodiment, a rehabilitative training device for use with a stroke patient includes a first component that is operatively coupled to a first body part (unaffected body part) of the patient and a second component that is operatively coupled to a second body part (affected body part) of the patient. The first component and second component are operatively coupled to one another such that motion of the first component as a result of movement of the first body part by the user causes the second component and second body part to move in a symmetrical motion.

A rolling footrest is provided and a method of using such by a wheelchair occupant. The footrest may optionally include a foot retainer, a platform and freely rolling castors. In some embodiments, replacing a fixed footrest will shorten the length of the wheelchair enabling the wheelchair to traverse sharp curves. In some embodiments, the footrest may include a swivel lock and/or a ratchet. In some embodiments the footrest may be used for therapeutic exercise. In some embodiments, the footrest may be used for propelling a wheelchair.

A modular passive-to-active exoskeleton system utilizes motor unit modules, an electromagnetic-clutch power transmission system, and biometric control. The passive exoskeleton has a stamina-increasing chairless chair function and optional use of magnetic ball-and-socket joints and knee torsion springs. To convert the exoskeleton system into an active robotic wearable device, modular attachments allow for motor units to be securely connected to the exoskeletal frame. An exoskeleton system may contain a knee motor unit that has a transmission system with an electromagnetic clutch that enables a passive mode, active mode, and/or hybrid mode. The motor units are controlled using wireless biometric motion sensors that measure limb joint angle and muscle activity. These motor units also communicate via wireless transmission with a central processing unit of the exoskeleton. This central processing unit serves as a gateway for user feedback from an Internet-of-Things (IoT) device, such as a smartphone, tablet, computer, etc.

A pulley attachment device for providing controlled passive range of motion (PROM) for shoulder rehabilitation includes an arm support member. The arm support member defines a hollow portion beneath a curved section to accommodate an immobile arm of a patient. The arm support member includes an extending member extending upward from the arm support member. The arm support member includes a handle grip extending downward from a distal end of the extending member. The handle grip provides a grasp for the patient. The arm support member includes straps configured to wrap around the arm support member to secure the immobile arm, and an arm support cable configured to connect to the arm support member or the extending member. The arm support cable provides a connection to a pulley cable of a pulley system to enable controlled movement of the immobile arm.

An assistive device that can be worn in normal daily activities that improves dorsiflexion in stance phase and correct hyperextension of the knee to help restore a functional gait pattern. The device includes an attachable foot stirrup strap, two long heavy duty elastic cords with hooks to attach to the foot stirrup strap and loops to attach to a shoulder strap, a thigh strap with clamp that allows for adjustment of tension to overcome foot drop and promote knee flexion in the proper direction by providing a point for the elastic cords to cross without entangling. Further, the shoulder strap includes a shoulder pad for comfort and a buckle that allows for adjustment of tension. Furthermore, the foot stirrup strap may be detachably connected to a foot/shoe of the user with the help of elastic connectors or permanently attached to the shoe with the help of an adhesive.

A device is provided for manipulating an arm of a user, thereby providing extension or flexion assistance to the arm about an elbow. The device has an arm engagement system, having an upper arm member with an upper arm frame having a pivot end and a distal end, a posterior elbow pad, a forearm member with a forearm frame having a pivot end and a distal end and a distal wrist pad, and a pivoting connection operatively coupled with the pivot end of the upper arm frame and the pivot end of the forearm frame. A force application system having a force applicator is connected between the distal end and the pivot end of the forearm frame. A force application mechanism is connected at or near the distal end of the upper arm frame.

Presented are wearable sensor systems for monitoring user movement, methods for making/using such systems, exoskeletons employing such systems, and wireless-enabled wearable sensor devices for performing biometric measurements. A sensor system for monitoring movement of a user includes a wearable sensor device that is communicatively connectable to a sensor linking node. The sensor linking node wirelessly receives sensor data from the wearable sensor device and wirelessly communicates the received sensor data to a remote computing node. The wearable sensor device includes an expandable device body, such as an elastic compression sleeve or an adjustable strap, that is worn on an appendage of the user. The device body includes a mounting interface, such as mating hook-and-loop fastener pads, that removably mounts thereon a biometric sensor core (BSC) unit. The BSC unit contains a microcontroller assembly that is integral with a microcontroller device, a biometric sensor array, and a wireless communication device.
