In one embodiment, the orthotic device can include a powered hand portion, a switching element, and a controller. The wearer can interact with the switching element to generate input signals for adjusting an operation of the powered hand portion. The controller can receive the input signals and generate control signals to accordingly adjust the operation of the powered hand portion. In some embodiments, a powered hand portion can be comprised of a plurality of linkages and at least one powered actuator to assist with an opening and closing of the hand portion. The plurality of linkages can be operated by at least one electric motor with quick-connect elements to link onto fingers of a user. In some embodiments, an electrically-actuated clutch mechanism can be affixed to an upper arm section and a lower arm section of an orthotic device. The clutch mechanism can be configured into different positions.

A prosthetic or orthotic device (POD) can include first and second limb members coupled at a joint, an actuator, and a controller. The actuator can be configured to actuate the first limb member relative to the second limb member. The controller can cause the actuator to exhibit a force rejection behavior during a portion of stance phase and cause the actuator to exhibit a force following behavior during a portion of swing phase. The controller can, based on a determination that a gait parameter satisfies a gait parameter threshold, cause the actuator to at least one of: apply a first torque at the joint to cause the POD to flex during a portion of stance phase, decelerate flexion of the POD during at least a first portion of the swing phase, or decelerate extension of the POD during at least a second portion of the swing phase.

An apparatus (10) for the rehabilitation, assistance and/or augmentation of arm strength in a user (U) comprises a support arrangement (12) for supporting the apparatus (10) on the user (U), a linkage arrangement (14) coupled to the support arrangement (12) and for coupling to an arm (A) of the user (U), and an actuation arrangement (16) for operating the linkage arrangement (14) and thereby manipulating the user's arm (A) in response to a user input signal.

An apparatus for determining balance compensation includes a platform, sensors and a processor. The platform is configured for a person to stand on the platform. The sensors are coupled to the platform and measure at least one of a weight and a pressure. The processor determines a balance of the person based on the measurements of the sensors.

A smart knee brace including a knee brace, multiple thigh bands, multiple shin bands, and multiple brace straps removably attached to one another and multiple motion actuators and sensors. Each motion actuator is connected to one brace strap and each sensor is connected to one motion actuator to measure an orientation of corresponding brace strap and generate a motion signal. A computing device receives the motion signals from the sensors; measures a current range of motion of the thigh, the shin, and the knee, and, based on the received motion signals, and generates drive signals based on the measured current range of motion. A native smart knee brace computer application on a smart phone of the user is operatively connected to the computing device and a cloud application server provide higher level analysis of the motions of the smart knee brace.

Disclosed is a lumbar support belt including: a support belt body intended to surround at least one part of a user's torso; at least a first sensor capable of measuring the pressure exerted by the support belt on a user or the elongation of the support belt body; and a module including at least a second sensor capable of measuring at least one parameter relating to the actimetry of the user. The module is removably attached to a second location of the support belt body.

A device and method for measuring prosthetic or orthotic slip is presented. An optical sensor device is attached to the prosthesis or orthosis and measures the amount of relative motion between the prosthetic socket and the residual limb surface or between the orthosis and the affected body part. The sensor device is comprised of an optical sensor, a light source, a processing unit and a power source contained within a housing. A system for measuring multidirectional prosthetic or orthotic slip using the sensor device and automatically adjusting the fit of the prosthetic based on a determined threshold is also presented.

A temporary cast that includes an exterior shell, a lining body including an inner layer, one or more integrated pressure sensors communicatively coupled to a controller, and a plurality of artificial muscles disposed between the inner layer and the exterior shell. Each of the plurality of artificial muscles is communicatively coupled to the controller and includes a housing including an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair includes a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing, where the electrode pair is actuatable between a non-actuated and actuated states such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region.

An orthopedic support and/or treatment system including a brace or sleeve comprising a power subsystem; a sensor subsystem; an adjustment mechanism; a software subsystem; a communication subsystem; and a telemedicine subsystem. The orthopedic treatment system includes and communicates over a network to a remote controlling device. The remote control device can be a computer, a mobile device, or any other controller. The sensor subsystem communicates to the remote control device, which in turn can be used to control the adjustment mechanism to adjust a tension or compression of the brace or sleeve.
