Abstract: A prosthetic foot can include a resilient heel member that can be removably coupled to the bottom of a plate-like foot member of the prosthetic foot. The heel member can be made of a resilient material, such as foam. The heel member can have a shape that corresponds to a foot cover and allows the prosthetic foot to fit within a foot cover. A lip may be provided to engage with a corresponding portion of the foot cover to secure the heel member within the foot cover. A rib can be located on the bottom of the heel member to create horizontal or vertical displacement of the foot at heel strike. A recess can be created in the heel member to removably receive an insert, which can alter the stiffness of the heel member.

Abstract: Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

Abstract: A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface.

Abstract: A cervical collar including an anterior portion having a rigid or semi-rigid shell anterior main support piece. The anterior portion defines resilient or flexible edges formed along the periphery of the main support piece. The flexible edges form a three-dimensional anatomically configured proximal support portion defined along a proximal area of the anterior portion. The anterior main support piece defines a supporting spring portion centrally located along the proximal area of the anterior portion. The proximal support portion is formed around and encompasses the supporting spring portion.

Abstract: Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual.

Abstract: A low profile prosthetic foot comprises a foot member extending at an incline from an anterior portion to a posterior portion thereof and configured to flex during motion, and an adapter mounted solely at a posterior section thereof to the posterior portion of the foot member so that the adapter's anterior section can move relative to the foot member and “roll-up” onto the foot member during motion.

Abstract: Disclosed are adjustable powered rehabilitation devices and methods for using the same to rehabilitate and/or train a user. The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.

The system may include a plurality of mechatronic devices, each of which may be in communication with at least one other of the plurality of mechatronic devices. Each of the mechatronic devices includes one or more of a processor, an actuator, or a sensor. One or more of the mechatronic devices may be configured to generate a control state for at least one other of the plurality of mechatronic devices based on the communicated data.

Abstract: A wearable device having feedback characteristics including a compliant article arranged to extend over an anatomical portion of a wearer and for providing a user with information regarding range of motion parameters of a joint and/or to condition users to maintain proper joint orientations. Sensors provided with the wearable device detect the orientation of the joint and send signals to a processor for analysis.

The sensors, processor, and feedback mechanisms can be provided in a monitoring and control package along a side of the compliant article.

Abstract: A prosthetic or orthotic system including a sensor module and a processing module usable to determine a terrain variable, such as a terrain transition. In certain examples, the system is capable of anticipating a terrain transition prior to the user experiencing the terrain transition, which may include, for instance, a transition from level ground walking to walking on stairs or may include a change in a slope of the ground surface. In certain embodiments, the system advantageously monitors a posture and/or movement of the patient to anticipate the terrain transition. Furthermore, the system may control an actuator to appropriately adjust the prosthetic or orthotic device to encounter the anticipated terrain transition.

The system may further detect when the user has moved to exit the relaxed position, and may actively adjust the angle between the members of the ankle to an exit state.
