Abstract: An orthosis includes a first portion and a second portion configured to attach on opposite sides of a joint. An actuator is configured to apply a force between the first and second portions. The actuator includes a first spool and a second spool rotatably mounted to the first portion. An output pulley is mounted to the second portion. A belt has a first end wrapped around the first spool, a second end wrapped around the second spool, and a mid-portion wrapped around the output pulley. The actuator is configured to rotate the first and second spools. The rotation of the first spool pulls the belt a given length, and the rotation of the second spool feeds the belt less than the given length, so as to pull the output pulley towards the first portion to pull the second portion towards the first portion.

Abstract: The invention relates to embodiments of methods for extending a subject-controllable range of joint motion, and for increasing subject control of joint movement within a range of motion. Embodiments include fastening a powered device around a joint so as to be able to control the joint, allowing the subject to move the joint within a range of volitional motion, and then engaging the powered device to support movement of the joint into an expanded, rehabilitative range. In some embodiments, the device supports joint movement by substantially providing the force to move the joint beyond the volitional boundary. In other embodiments, supporting movement includes the subject substantially providing the force, and the device allowing movement only in a desired direction. The invention further relates to a system for increasing the functional capability of a joint by implementing embodiments of the method. By such methods and system, rehabilitation is accomplished both by building strength, and training neural pathways.

Abstract: Portable devices and methods for preventing deep vein thrombosis (DVT) by assuring that the ankle is flexed and extended sufficiently to promote blood flow in the lower leg are disclosed. The device includes an actuator with a free movement mode that allows a patient to move freely between activations or to initiate movement to delay a next automatic activation.

Abstract: A foot pad device includes a foot pad, force sensors that provide force data, sensor electronics coupled to the force sensors, and a processor. The foot pad includes a ball region configured to be located under a ball of the foot of the user or a heel region configured to be located under a heel of the foot of the user. At least a portion of the force sensors is located in the ball region or the heel region of the foot pad. The sensor electronics include a flexible circuit with force sensor connection paths adapted to transmit force data from the force sensors and are configured to condition the force data to be within a conditioned force data range. The processor is configured to calculate a weight value based on the conditioned force data, a gain value, and an offset value.
