The present invention provides an actuator-equipped knee ankle foot orthosis in which a control device calculates a thigh phase angle based on an angle-related signal detected by a thigh orientation detecting means at one sampling point, applies the thigh phase angle at that sampling point to an assisting force control data, which is stored in the control device in advance and indicates the relationship between the thigh phase angle and a size of the assisting force to be imparted to a lower leg-side brace, to obtain the size of the assisting force to be imparted to the lower leg-side brace at that sampling point, and executes operational control for an actuator unit such that the assisting force having the size is output.

In some embodiments, a device for assisting motion of a joint may include a first anchor on a first side of the joint, a second anchor on a second side of the joint, a spring operatively coupled to the first anchor and the second anchor, and an actuator operatively coupled to the first anchor and the second anchor. Actuating the actuator may apply a torque about the joint that is resisted by a reaction torque applied to the joint by the spring.

Examples of a motion guiding device of a target joint of a target body are disclosed. The device allows three degree-of-freedom (DOF) motion about a remote center of rotation that is approximately aligned to a center of rotation of the target joint. The device comprises a base adjustably connected to the target body and three rotary joints interconnected with a network of linkages. One end of the network of linkages is connected to the base and the opposite end to an effector plate. At least one of the three rotary joints is not aligned with an axes of motion of the target joint and any of these rotary joints may be positioned under angle with respect to the others. Each of the rotary joints provides one DOF of rotary motion about the respective axes and each axis of the three rotary joints intersect at the remote center of rotation. The geometry of the network of linkages is adjustable to adjust a position of the remote center of rotation in three dimensions. The three rotary joints and the network of linkages rotate the effector plate about the remote center of rotation that is approximately align with the center of rotation of the target joint. This system may be connected with one or more parallel branches for additional actuation.

An orthopaedic device includes an upper exoskeleton (2, 4) and a lower exoskeleton (6), and a receiving actuator having a pivot-connection member (10). The exoskeleton is hinged with respect to one another via the pivot-connection member. A receiving transmission device (30) is designed to be able to transmit a movement to the pivot-connection member. At least a first hydraulic cylinder (20) is coupled to the receiving transmission device so as to be able to rotate said pivot-connection member. An emitting actuator has at least a first hydraulic emitting cylinder (51, 55), an emitting transmission device (60), and a motor device (70) coupled to the emitting transmission device. At least one pressurized-fluid-guiding line (42, 45) is designed to allow a hydraulic transmission of movement from the first emitting cylinder to the receiving actuator.

An adjustable knee ankle foot orthosis for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

There is disclosed a mobility aid for use by a user having a lower body amputation site. The mobility aid includes a lower body exoskeleton (LBE). The LBE has a pelvic support structure and a first leg and a second leg. Each of the first and second legs are movably coupled to the pelvic support structure, wherein at least the first and second legs are selectively actuable to move the lower body exoskeleton relative to a surface on which the mobility aid is positioned. The LBE also includes a carrier selectively positionable with respect to the lower body exoskeleton and, which in use, supports the user at or about an amputation site; and a harness system configured to, when in use, secure the user to the lower body exoskeleton.

A gait motion assisting apparatus of the present invention includes an actuator unit controlling driver so that assisting force calculated by applying gait motion timing based on detected thigh phase angle to output pattern saved data is imparted to lower leg, and a terminal device capable of wireless-communicating with control device of the actuator unit. The terminal device can receive assisting force setting value including assisting force imparting period during gait cycle and create, based on the assisting force setting value, output pattern setting data indicating a relationship between the gait motion timing and a size of assisting force to be imparted to the lower leg. The control device is configured to overwrite-save the output pattern setting data received from the terminal device as the output pattern saved data.

An acquisition unit acquires a classification result obtained by classifying training assistants by performing a cluster analysis based on first rehabilitation data about rehabilitation performed by the trainee by using the rehabilitation support system, the first rehabilitation data including at least assistant data indicating a training assistant and index data indicating a degree of recovery of the trainee. A learning unit generates a learning model, the learning model being configured to input second rehabilitation data including at least the action data indicating an assisting action performed by the training assistant to assist the trainee and output the action data for suggesting a next action to be performed by the training assistant. The learning unit generates the learning model by using, as teacher data, the second rehabilitation data for which pre-processing has been performed based on the classification result.

A method of treating knee abnormalities includes securing the portion of the leg above the knee to a stationary object and securing the portion of the leg below the knee to a movable support. A force is applied to the movable support to stretch the knee joint. An apparatus for carrying out the method is also disclosed. The apparatus may be fitted with a controller system which allows the apparatus to be operated wirelessly from a mobile device running a mobile application, which may communicate with a web-based portal and/or database.

A processing system capable of educating a training assistant, who assists a trainee when the trainee performs rehabilitation by using a walking training apparatus, in order to enable the training assistant to appropriately assist the trainee is provided. The processing system includes a determination unit and an output unit. The determination unit determines an adjustment-required parameter, the adjustment-required parameter being, among parameters that can be adjusted in a walking training apparatus, a parameter of which a frequency of adjustments by a training assistant who assists a trainee performing walking training in the walking training apparatus or by an assistant in a hospital other than the training assistant is lower than an adjustment criterion. The output unit outputs parameter information indicating the adjustment-required parameter and effect information indicating an adjustment effect that is obtained when the adjustment-required parameter is adjusted.
