Abstract:
A low-cost, virtual environment, rehabilitation system and a glove input device for patients suffering from stroke or other neurological impairments for independent, in-home use, to improve upper extremity motor function, including hand and finger control. The system includes a low-cost input device for tracking arm, hand, and finger movement; an open source gaming engine; and a processing device. The system is controllable to provide four types of multiple patient/user interactions: competition, cooperation, counter-operative, and mixed.
Abstract:
A method of constructing a sensor includes depositing a first material in a predetermined arrangement to form a structure. The depositing results in at least one void occurring within the structure. The method further includes depositing a second material within the voids. The second material may have electrical properties that vary according to deformation of the second material. The method also includes providing electrical access to the second material to enable observation of the one or more electrical properties. A sensor includes a structure that has one or more voids distributed within the structure. The sensor also includes a material deposited within the one or more voids. The material may be characterized by one or more electrical properties such as piezoresistivity. The sensor includes a first contact electrically coupled to a first location on the material, and a second contact electrically coupled to a second location on the material.
Abstract:
A rehabilitation system that combines robotics and interactive gaming to facilitate performance of task- specific, repetitive, upper extremity/hand motor tasks, to enable individuals undergoing rehabilitation to improve the performance of coordinated movements of the forearm and hand is disclosed. More specifically, the rehabilitation system includes a two degree-of -freedom (DOF) robotic, upper limb rehabilitation system and interactive gaming hardware that is coupled to a computer, to provide a virtual reality- like environment.
Abstract:
An exercising and rehabilitation hand device is disclosed. The hand device according to the invention is portable and controllable by smart fluid-based brakes/dampers to provide a compact, lightweight mechanism whose resistance to motion can be changed on- the- fly, through computerize control, to vary the exercises that can be performed and tune the workout or rehabilitation session to the responses of the user.
Abstract:
The present application is directed towards methods and systems for an add-on smart pedal and computer based application to provide cyclist monitoring and recommendations. The methods include displaying, by a virtual coach, characteristics of a bike in a first virtual cycling session, the characteristics measured by a pedal sensor during a cycling session. The virtual coach may assess a performance of a rider during the cycling session and generate recommendations the first virtual cycling session based on the performance of the rider. Further, the virtual coach may create a second virtual cycling session based on the rider performance and the recommendations.
Abstract:
A robotic gait rehabilitation (RGR) training system is provided to address secondary gait deviations such as hip-hiking. An actuation assembly follows the natural motions of a user's pelvis, while applying corrective moments to pelvic obliquity. A human-robot interface (HRI), in the form of a lower body exoskeleton, is provided to improve the transfer of corrective moments to the pelvis. The system includes an impedance control system incorporating backdrivability that is able to modulate the forces applied onto the body depending on the patient's efforts. Various protocols for use of the system are provided.

Abstract:
Electro-rheological fluid brake or actuator devices provide controllable resistance with or without inclusion of active torque output in either direction of rotation under manual or computer control. The brake and actuator devices are suitable for use in an orthotic device for a joint, such as the knee or elbow.
Abstract:
The Active Knee Rehabilitation Orthotic System (ANdROS) is a wearable and portable assistive tool for gait rehabilitation and monitoring of people with motor control deficits due to a neurological ailment, such as stroke. ANdROS reinforces a desired gait pattern by continually applying a corrective torque around the knee joint, commanded by a impedance controller. A sensorized yet unactuated brace worn on the unimpaired leg is used to synchronize the playback of the desired trajectory based on the user's intent. The device is mechanically grounded through two ankle foot orthoses (AFOs) rigidly attached to the main structure, which helps reduce the weight perceived by the user.
Abstract:
Current Rapid Prototyping (RP) technology allows for single step manufacturing of complex mechanisms with embedded parts. The ability to quickly move from concept to workable prototype is essential in a fast-paced field such as medicine. A patient specific ankle- foot orthotic device using this technology is disclosed. This exemplary device is used to help stabilize the ankle-foot region in patients with limited mobility, and, more specifically, the medical condition drop foot. The purpose of this device is to match or exceed the fit, comfort and effectiveness of a standard orthotic device while giving attention to the patient's specific needs and anatomy.
