| 20140276264 | STRAP ASSEMBLY FOR USE IN AN EXOSKELETON APPARATUS - An exoskeleton for a limb of a user utilizes an air bladder strap, which may be monitored and the pressure therein adjusted from time to time. | 09-18-2014 |
| 20140276265 | FOOT PLATE ASSEMBLY FOR USE IN AN EXOSKELETON APPARATUS - An exoskeleton for a leg of a user comprises a leg structure, a foot plate moveably mounted thereto, and a biasing member extending between the leg structure and the foot plate, the foot plate is moveably mounted to the leg structure between a first position in which the rearward portion extends downwardly and the forward portion extends upwardly and a second position in which the rearward portion extends upwardly and the forward portion extends downwardly and the foot plate is biased to the first position. | 09-18-2014 |
| 20150141878 | METHOD AND APPARATUS FOR PROVIDING DEFICIT-ADJUSTED ADAPTIVE ASSISTANCE DURING MOVEMENT PHASES OF AN IMPAIRED JOINT - A method is described for providing deficit-adjusted adaptive assistance during movement phases of an impaired joint. The method includes determining, on a processor, a current movement phase for a compound joint function based on sensor data. The method further includes determining, on the processor, a respective robot state parameter trace for each movement phase in a normal and impaired subject. The method further includes determining, on the processor, a deficit parameter for each movement phase. The method further includes determining, on the processor, an adaptive magnitude for the robot applied torque based on the deficit parameter of the current movement phase. The method further includes applying, to the robot joint, the adaptive magnitude for the robot applied torque for the current movement phase, based on an adaptive timing for the current movement phase. An apparatus is also described for providing deficit-adjusted adaptive assistance during movement phases of the impaired joint. | 05-21-2015 |
| 20150351992 | Leg Lifter - The present invention provides a leg lifter for those having lower extremity injuries or limited lower extremity strength to facilitate movement. The leg lifter includes a wrapping portion configured to encircle a user's ankle via a fastener. The wrapping portion further includes an adjustable strap that extends outwardly and orthogonally from substantially a midpoint of the wrapping portion. The adjustable strap includes a proximal end and a distal end, wherein the proximal end is affixed to the wrapping portion. The distal end is adapted to be held by a user for lifting the adjustable strap, thus causing the user's lower extremity to be lifted. The distal end further includes a fastener that allows a user to removably attach the distal end to his or her clothing. The adjustable strap is configured to be lengthened or shortened to improve a user's movement and achieve independence from caretakers. | 12-10-2015 |
| 20150366736 | CONTINUOUS PASSIVE MOTION DEVICE - A CPM device includes a support structure arranged to be removably attached to an articulating brace supporting a limb and a joint of a user. One or more rotating members are rotatably connected to the support structure. The rotating members are adapted to contact and roll on an underlying surface that is separate from the CPM device. At least one motor is arranged to apply a torque to the rotating members such that the rotating members roll on the underlying surface. The rolling of the rotating members on the underlying surface causes the support structure to translate over the underlying surface, which, in turn, conveys a bending force to the joint. | 12-24-2015 |
