An ankle foot orthosis having a lower leg element, a foot element being pivotably coupled to the lower leg element around a pivot axis, and a first energy storing unit being adapted such that moving the foot element relative to the lower leg element in dorsiflexion direction from a position in which the amount of energy stored in the first energy storing unit is minimal loads the first energy storing unit with energy. The first energy storing unit is adapted such that the amount of energy stored in the first energy storing unit is increased by moving the foot element relative to the lower leg element in a plantar flexion direction from a first position in which the amount of energy stored in the first energy storing unit is minimal into a second position and moving the foot element relative to the lower leg element in dorsiflexion direction from the second position back into the first position.

A powered orthotic device includes a brace, a finger engagement member, a thumb engagement member, and a hand actuator. The powered orthotic device includes a locking mechanism affixed to the brace, and a finger carrier assembly with a finger carrier to engage the fingers of the wearer, as well as an affixment member configured to be removably attached to the locking mechanism. The wearer dons the orthotic device, without assistance from another, by placing the set of fingers into the finger carrier and using a free hand of the wearer to affix the affixment member to the locking mechanism.

The present disclosure relates to a device including electrostatic brakes providing haptic kinaesthetic feedback to a user in e.g. assistive, rehabilitation or virtual reality scenarios, as well as tele-manipulation.

Methods for installing brackets that protect the heel of a person wearing a non-loadbearing cast. In one embodiment two brackets are attached at two points on opposite sides of the foot, with one bracket below the heel and the other behind the heel with roughly 0.75 inch clearance. This arrangement serves to redirect a load that would have been applied to the heel. The loads are now directed to either side of the ankle at the two attachment points.

An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.

A therapeutic pressure applicator with a sensor and transceiver is worn by a patient during daily activity to apply pressure to a specific body part, and used in a system with a device such as a cell phone to receive and display real-time pressure data to alert the patient and physician when the pressure is outside a desired range. The applicator includes a securement member and a pressure adjusting device with a pressure adjusting dial, pressure sensing component, pressure focusing plate and cushion. Rotating the dial retracts or extends the sensing component, focusing plate and cushion. The applicator has a computer module with a CPU, memory, transceiver, power source and a force sensor. A pressure button is pressed into engagement with the sensor to transmit real-time focused pressure data to the CPU. The transceiver communicates the real-time cushion pressure data to the cell phone that displays and stores the data.

Some embodiments include a knee therapy system that includes a flexible garment or wrap that is electrically conductive, and a range-of-motion sensor coupled or integrated with the flexible garment or wrap. The sensor is coupled or integrated with the flexible garment or wrap, and includes a plurality of electrodes including an active electrode and a receiving electrode. The electrodes can be in physical contact with skin of a patient forming an electrical circuit with control electronics of the controller. The electrical circuit measures an electrical parameter using the active and receiving electrodes, and forms a closed loop electrical muscle stimulation system, where stimulation current or voltage is applied by the electrodes onto the skin between the active and receiving electrodes based on a program and an electrical parameter measured through the electrodes. An optical sensor or camera can be configured to track body joints of a user.

Various embodiments of the present technology generally relate to robotics and prosthetics. More specifically, some embodiments of the present technology relate to multi-modal fingertip sensors with proximity, contact, and for localization capabilities. Various embodiments of the present technology provide for a novel multi-modal tactile sensor which comprises an infrared proximity sensor and a barometric pressure sensor embedded in an elastomer layer. Signals from both of these sensors can be fused to measure proximity (0-10 mm), contact (0N), force (0-50N) and localize impact at five spatial locations and three angles of incidence. Gaussian processes in a regression setting can be used to obtain calibrated force measurements with an R-squared value of 0.99. Supervised machine learning approaches can be used to localize the position and direction of probing with classification accuracies of 96% and 89% respectively.

An embodiment of the invention includes (a) modeling a first internal force applied to a model of a user's joint based on a first external force externally applied to the joint at a first position; (b) modeling a second internal force applied to the model based on a second external force externally applied to the joint at a second position unequal to the first position; (c) comparing the first and second modeled internal forces; and (d) stimulating the user based on the comparison. Other embodiments are described herein.
