Systems and methods are described for the coaching of users through successful calibration of a myoelectric prosthetic controller. The systems and methods are comprised of, and/or utilize, hardware and software components to input and analyze electromyography (EMG) based signals in association with movements, and to calibrate and output feedback about the signals. The hardware is further comprised of an apparatus for the detection of EMG signals, a prosthesis, an indicator, and a user interface. The software is further comprised of a user interface, a pattern recognition component, a calibration procedure, and a feedback mechanism. The systems and methods facilitate calibration of a myoelectric controller and provides the user with feedback about the calibration including information of the signal inputs and outputs, and messages about connected hardware and how to optimize signal data.

A computer-implemented method of detecting physiological attributes of a wearer of a computerized wearable device having one or more sensors comprises (1) using the information from the one or more sensors to assess the physiology of the wearer; and (2) notifying the wearer of the wearer's physiology. In various embodiments, the method involves using the wearable device to determine the wearer's current posture, balance, alertness, and/or physical state and comparing the current posture, balance, alertness and/or physical state to at least one baseline measurement. For example, the system may measure a baseline posture to determine when the wearer's current posture deviates from the baseline posture, and notify the wearer so that the wearer may improve his or her posture. In other embodiments, the computerized wearable device may detect one or more of the wearer's physiological characteristics (e.g., oxygen levels, pulse rate, pupil size, etc.) and determine the wearer's alertness level.

A method includes fixing at least one sensor to a body part of a person, sending signals, with the at least one sensor, to an electronic data processing device, the signals containing measurement data and an individual sensor identifier, and determining, with the electronic data processing device, the body part on which the sensor is arranged or is to be arranged, and allocating the measurement data of the at least one sensor to the body part.

In some embodiments of a prosthetic or orthotic ankle/foot, a prediction is made of what the walking speed will be during an upcoming step. When the predicted walking speed is slow, the characteristics of the apparatus are then modified so that less net-work that is performed during that step (as compared to when the predicted walking speed is fast). This may be implemented using one sensor from which the walking speed can be predicted, and a second sensor from which ankle torque can be determined. A controller receives inputs from those sensors, and controls a motor's torque so that the torque for slow walking speeds is lower than the torque for fast walking speeds. This reduces the work performed by the actuator over a gait cycle and the peak actuator power delivered during the gait cycle. In some embodiments, a series elastic element is connected in series with a motor that can drive the ankle, and at least one sensor is provided with an output from which a deflection of the series elastic element can be determined. A controller determines a desired torque based on the output, and controls the motor's torque based on the determined desired torque.

Eyewear or any other suitable wearable device may include one or more sensors for monitoring the gait of an individual. Information from the one or more sensors is analyzed to identify one or more medical conditions associated with the individual or to assess an individual's recovery from a particular injury or medical procedure.

A wearable device includes at least one sensor for obtaining a unique identifier from the wearer when the wearer and for transmitting the unique identifier to one or more computer processors for use in determining whether the wearer is a particular individual. The wearable device may also include a wireless communications device for transmitting a signal (e.g., to a remote computing device) that confirms the identity of the wearer as the particular individual. A remote computing device, or other device, or individual, may then, based at least in part on receiving the signal, grant wearer access to a computer program, computing system, and/or a particular physical space.

The present invention includes two embodiments of a tethered ankle-foot prosthesis, one with a single toe to provide plantarflexion and with two independently-actuated toes that are coordinated to provide plantarflexion and inversion-eversion torques. An end-effector was designed which is worn by a subject, and which was integrated with existing off-board motor and control hardware, to facilitate high bandwidth torque control. The platform is suitable for haptic rendering of virtual devices in experiments with humans, which may reveal strategies for improving balance or allow controlled comparisons of conventional prosthesis features. A similar morphology is also effective for autonomous devices.

A prosthetic limb test fixture is configured to mimic a human stride. An electronic management system can control the test fixture to follow the position and pattern of a particular selected gait cycle during testing. A proposed prosthesis can be attached to the test fixture. Sensor data collected during testing can be evaluated to determine whether the proposed prosthesis is likely to appropriately fit an amputee patient. Iterative adjustments may be made to the prosthesis based on test data in order to maximize the likelihood of a good fit.

A walking simulator includes: a lower-limb prosthetic device having at least a foot portion, a tibial element, and an ankle articular center suitable to connect the foot portion to the tibial element; a base structure, an arm coupled to the base structure via a coupler that allows the arm to rotate or pivot about a substantially horizontal axis of rotation, wherein the arm includes a fastener for constraining the prosthetic device to the arm so that it extends substantially parallel to the arm; a substantially horizontal base positioned under the prosthetic device, wherein the base includes a top portion suitable to receive in abutment a sole of the foot portion of the prosthetic device; a first actuator associated with the arm for creating a pivoting or oscillating rotary motion of the arm about the axis of rotation and for controlling the leg angle of the prosthetic device constrained to the arm.

A prosthetic device includes a phalanges portion, a metatarsals portion that is movably coupled to the phalanges portion, an ankle portion that is movably coupled to the metatarsals portion, and a calcaneus portion that is movably coupled to the ankle portion.
