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 brace includes a frame having first and second sections defined by a clearance, a rotary ratcheting mechanism connected to the frame, and an elongate tensioning element having a first end secured to the ratcheting mechanism and a second end connected to the frame. The ratcheting mechanism is configured for unidirectional incremental adjustment in distance in a first direction of the second end of the tensioning element relative to the ratcheting mechanism, and includes a release device configured to release the tensioning element relative to the ratcheting mechanism in a second direction relative to the ratcheting mechanism.

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.

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: A cervical collar has an anterior portion and a posterior portion having side extending portions removably connecting to the anterior portion. The posterior portion includes a rigid or semi-rigid main support piece and a resilient edge integrally secured to at least a substantial portion of a periphery of the main support piece that is substantially more flexible than the main support piece. The main support piece defines opposed upper side sections and a lower section. The upper side sections extend upwardly from the side extending portions and are oriented toward a proximal middle region and spaced apart by a first distance. The lower section extends continuously between the side extending portions and is spaced a second distance from the upper side sections.

Abstract: An orthopedic device has at least one flexible or rigid frame member contoured to generally correspond to an anatomical limb. The device also includes a tightening system having a dial tensioning device and at least one cable and/or strap connected to the dial tensioning device. The dial tensioning device has a rotary ratchet permitting incremental adjustment of the cable and/or strap. Adjustment of the dial tensioner in a first direction secures the frame member to the limb.

Abstract: An orthopedic device includes a textile panel having interior and exterior surfaces, and a first stabilizer assembly including a first tubular welt sewn or knitted within and extending from an exterior surface of the textile panel. A first cable is slidably extending through the tubular welt and a strap is connected to a first end of the cable extending from a first opening of the welt, and the strap is adjustably securable over the textile panel. The orthopedic device may include various portions of stretchability and features for receiving components for the orthopedic device.

Abstract: A strap attachment system includes a frame member having an opening, a strap, and a tab having a body and an attachment element defined by the body. The tab connects to the strap. A fastener element connects to the tab and is detachably and slidably mountable to the frame member by the opening.

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.

Abstract: Prosthetic devices and methods of controlling the same are provided. A prosthetic ankle device includes a foot unit and lower limb member moveable relative to one another and defining an ankle angle therebetween. The prosthetic ankle device further includes a controller to operate the device using different ankle angles depending on, for example, a user's gait speed. Methods of controlling the prosthetic ankle device include operating the device at different ankle angles depending on gait speed. For example, the prosthetic ankle device can provide for relatively more dorsiflexion at relatively slower gait speeds and relatively more plantarflexion at relatively faster gait speeds.

Abstract: A prosthetic foot includes a foot member, a heel member operatively coupled to the foot member. At least one of the heel member and foot member define an arch portion that faces a support surface that the prosthetic foot contacts during use. An insole member contacts said arch portion, the insole member configured to facilitate a rollover of the prosthetic foot in at least one of a lateral-medial and a medial-lateral direction during ambulation.
