  • Patent number: 8784502
    Abstract: A computerized prosthesis alignment system includes a transducer that can measure socket reactions in the anterior/posterior plane and the right/left planes, while canceling or reducing the transverse forces on the measurements of these socket reactions. In addition, the transducer is also capable of determining the axial load or weight experienced by the prosthesis. The computerized prosthesis alignment system is in communication with a host computer. The moment data from the transducer is interpreted by the user via a computer interface. The host computer includes memory for storing one or more applications. These applications receive data from the transducer, interpret the data with discrete algebraic or fuzzy logic algorithms, and display the output numerically and graphically. Applications may also interpret the data to provide analysis to the user for aligning the prosthesis.

  • Patent number: 8674838
    Abstract: A walking assist device which allays uneasiness felt by a user when a wearable device actively applies torque to a leg. A walking assist device comprises a controller, a headphone and a wearable device attached to left and right legs. The wearable device has a sensor that detects motion of the user's leg and a motor that applies torque to a joint of the user's leg. The controller controls the wearable device such that the joint angle of the user follows a target pattern which represents time-dependent changes of a target joint angle. The controller specifies a change timing at which a time-dependent change of the target joint angle in the target pattern meets a predetermined condition, and informs the user, before the specified change timing, that the change timing is arriving. The uneasiness felt by the user when an actuator actively applies torque to the leg joint is allayed by informing the user of the motion before the actuator performs that motion.

    Abstract: An adaptable mounting plate is secured to and thereby combined with a stilt boot plate. The mounting plate pivotally couples a quick-release ratcheting strap and an adjustable arched heel backer to the stilt boot plate. The mounting plate and backer keep a user's feet in correct position, thereby providing both lateral and forward stability needed during movement. The pivotal quick release ratcheting strap simultaneously drives the user's heel into the arched heel backer, ensuring a secure coupling therebetween, and draws the user's shoe or boot tightly down against the stilt boot plate. The toe strap is also preferably a quick-release ratcheting strap, and is preferably attached in existing toe strap mounting holes. Likewise, the upper calf support utilizes the same type of quick-release ratcheting strap as the ankle, and is preferably mounted with nylon lock nuts through mounting holes on the calf support.

  • Patent number: 7981003
    Abstract: The present invention combines an articulated stilt with a rear-mounted leg support or brace behind the leg of the user. The articulating stilt has a foot operative to contact a surface to be traversed, a boot rest operative to support a human foot thereon extending in a longitudinal direction between a heel region and toe region and thereby defining a longitudinal axis, and at least two risers extending between the foot and boot rest coupled thereto through pivotal joints. The rear leg brace has an upper leg binding, and an extension coupling the upper leg binding to articulating stilt. According to further manifestations, the rear leg brace may be fixed or pivotal relative to the risers, and when pivotal, may be adjusted to user preferred angular orientations. The use of a rear-mounted brace eliminates undesirable torque during movement, enabling a more anatomically and bio-mechanically correct movement.

  • Patent number: 6932096
    Abstract: The present invention relates to an ordinary crutch modified with a straight support which may be formed from a solid, lightweight tubular member, said support connected at one end to near the bottom portion of the crutch and with a bicycle pedal-like cushion on the other end for which the calf, shin or cast of the injured leg or leg of the injured foot rests. Since the pedal can freely revolve from its attachment to the solid support member, the angle at which the leg rests on the pedal relative to the crutch may be readily optimized for the patient's comfort in order to relieve pain and discomfort. Also, fatigue from the body when supporting the dangling leg may be avoided as the leg no longer dangles with its concomitant “dead weight”, because the entire weight of the leg is resting on the cushion of the leg support, the knee is flexed or extended while standing, or while sifting.

  • Patent number: 5178595
    Abstract: Unlike the prior art crutch that in essence extends the shoulder to the ground to bear the weight of the injured person when walking, the novel walking device of the invention includes an upright staff that extends the pelvis to the ground on the side of an injury. Upper and lower receiving members for receiving and securing to the thigh and calf of an injured leg are attached to the staff and securing means secure the thigh and calf to said receiving means. The injured limb bears the load in compression rather than in shear.

  • Patent number: 5011136
    Abstract: This invention relates to improvements in a resilient leg brace which acts in parallel with a runner's legs to support his or her weight during foot impact, to store the kinetic energy of vertical motion, and to release said energy thrusting the runner back into the air during take-off. The running brace is energy efficient in that it stores and releases the maximum amount of vertical kinetic energy so that the leg muscles do not need to supply as much energy to lift the runner's weight during each step. The running brace also protects the legs and other parts of the body from impact damage. The leg brace is attached to a pelvic harness, and optional back and neck braces are attached to the shoulders and the chin to protect the back and neck from impact shock. The first improvement relates to an asymmetric travel structure which enables the running brace to deliver an upward thrust over a greater distance than that required to absorb the runner's downward impact.

  • Patent number: 4735754
    Abstract: Disclosed is a method of fabricating a prosthetic member (112) having personalized features of the patient, and being formed to provide an individualized fit to the patient's extremity (18). A rigid jacket (30, 32) is first formed around the uninsured foot (10) and the amputated extremity (18). The limb characteristics are impressed into an alginate (44) lining within the jackets (30, 32). A stone material poured into the alginate lining (44) forms stone models (48, 50) of the patient's limbs. A wax preliminary model (64) is scuplted in the likeness of the stone foot model (48) and used to form final stone mold halves (100, 102). The contour of the stone extremity model (50) is adjusted according to the tissue texture of the patient to provide an individualized fit. A gelatinous silicone is injected inside the final mold (100, 102) and allowed to form around the extremity model (50) to thereby provide the body of the prosthetic member (112) and the conformal sleeve (132 ).

  • Patent number: 4608054
    Abstract: An adjustable connection for adjoining parts of an artificial limb comprises a first and a second coupling element, each of which forms part of or is intended to be fixed to a respective one of the aforementioned artificial-limb parts to be connected together. The adjustable connection includes set screws which are intended to hold the coupling elements, and therewith the artificial-limb parts releasably in desired positions relative to one another. The coupling elements have centrally located, mutually coacting support surfaces, and the set screws are arranged in an outer annular flange which depends from one coupling element and encircles the other coupling element with a clearance between the elements, and which has an unloaded annular edge.
