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. When the processor determines that the joint is outside of predefined range of motion parameters or in an unsafe or potentially injurious configuration, a feedback or response mechanism is activated to alert the user to such a condition or to provide substantially rigid structural support to the joint. The sensors, processor, and feedback mechanisms can be provided in a monitoring and control package along a side of the compliant article.

Abstract: A wearable device having feedback characteristics including a compliant article that is arranged to extend over an anatomical portion of a wearer. Sensors provided with the wearable device detect the orientation of a joint and send signals to a processor for analysis. When the processor determines that the joint is in an unsafe or potentially injurious configuration, a feedback or response mechanism is activated to alert the user to such a condition and/or to provide substantially rigid structural support to the joint. The device may also be used to condition users to maintain the joint in proper orientations to avoid injuries, or to condition an amputee to use more effective motions to achieve a more natural gait.

Abstract: A knee brace divided into anterior and posterior sides by a frontal plane, and having first and second sides divided by a median plane. The knee brace having a frame, and at least one cross strap that is connected to the frame and extends across over at least a portion of the first and second brace sides. The at least one cross strap is arranged obliquely relative to the median plane. The brace also includes a tightening mechanism that is connected to the frame and is configured to incrementally tension the at least one cross strap at predefined settings and to release tension on the at least one cross strap. A first end of the at least one cross strap engages the tightening mechanism. A dosage meter is connected to the frame, and includes an indication feature representing tension settings of the at least one cross strap.

Abstract: An orthopedic device includes a rigid frame assembly having rigid frame supports connected by joints. The device also includes a strap which extends between sides of the frame assembly. An orthopedic component in the form of a resilient subshell is connected to and extending flexibly outwardly from the frame assembly. The subshell has a main body and a perimeter edge portion secured along the periphery of the main body wherein the perimeter edge portion is formed from a material having less hardness than a material used to form the main body. The strap is connected to at least one end portion of the subshell.

Abstract: A patella protector assembly for use with an orthopedic device, wherein the patella protector assembly has a central shell, an upper shell slidably connected to the central shell, and a lower shell slidably connected to the central shell. The central shell includes a main shell and a flexible perimeter edge portion surrounding at least a section of the perimeter of the main shell. The perimeter edge portion has greater flexibility than the main shell. The upper and lower shells are arranged pivotally and telescopically relative to the central shell such that the central, upper and lower shells together form a continuous shell without gaps therebetween.

Abstract: An orthopedic component for use in orthopedic device includes, according to one embodiment, a first shell body defining first and second surfaces, and a resilient perimeter edge portion surrounding the perimeter of the first shell body. The edge portion has greater flexibility than the first shell body. The perimeter edge portion defines a lip extending over a portion of at least one of the first and second surfaces, and the lip is spaced a distance above the first shell body so as to define a clearance between the first shell body and the lip.
