Novel tools and techniques might provide for implementing image-based physiological status determination of users, and, in particular embodiments, for implementing physiological status determination of users based on marker-less motion-capture and generating appropriate remediation plans. In various embodiments, one or more cameras may be used to capture views of a user (e.g., an athlete, a person trying to live a healthy life, or the like) as the user is performing one or more set of motions, and the captured images may be overlaid with a skeletal framework that is compared with similar skeletal framework overlaid images for the same one or more sets of motions. The system can automatically determine a physical condition of the user or a probability that the user will suffer a physical condition based at least in part on an analysis of the comparison, which may be difficult or impossible to observe with the naked human eye.

The present disclosure provides a joint function monitoring device. The joint function monitoring device comprises a bottom base capable of being removably attached to a hinge of an assistive device, a shaft comprising a central pan coupled to the bottom base, and a distal part, a first sensor coupled to the central part of the shaft for monitoring a rotation angle of the shaft, and a belt module coupled to the distal pan of the shaft and capable of being removably attached to a support assembly of the assistive device. A length of the belt module is adjustable.

A data processing method performed by a computer for judging implant orientation data representing an orientation of a first implant part relative to a first bone, the first implant part being part of an implant pair which further comprises a second implant part for a second bone, the implant pair being envisaged to be implanted in a patient.

A data processing method performed by a computer for judging implant orientation data representing an orientation of a first implant part relative to a first bone, the first implant part being part of an implant pair which further comprises a second implant part for a second bone, the implant pair being envisaged to be implanted in a patient, comprising the steps of: -acquiring the implant orientation data, -acquiring second implant orientation data representing the orientation of the second implant part relative to the second bone, -acquiring implant shape data representing the shapes of the first and second implant parts, -acquiring activity data representing at least one desired activity of the patient to be possible after implanting the implant, wherein each desired activity has an associated range of motion between the first bone and the second bone, -calculating a range of motion volume, which represents possible orientations between the first bone and the second bone over three rotational axes, from the implant orientation data, the second implant orientation data and the implant shape data, and -judging the implant orientation data to be feasible if the ranges of motion of all desired activities lie within the range of motion volume.

A method and apparatus for estimating kinematic information of human motion are provided. The method and apparatus comprises, calculating a length change and angle of a leg spring from a trajectory of human motion by using a compliant walking model modeling a human leg as the spring, and estimating kinematic information including at least one of a ground reaction force, a lower limb angle, an ankle joint trajectory and an ankle joint torque by using the length change and the angle. The compliant walking model comprises an off-centered curvy foot modeling a human foot, a lower limb-ankle spring modeling ranging from the CoM to the ankle joint, and an ankle-foot spring modeling ranging from the ankle joint to the curvy foot.

A weight-bearing stance corrected foot orthotic (12) is adapted to be used on the foot (2) of a anaesthetised patient in the supine or prone position, the weight bearing stance corrected foot orthotic (12) adapted to dorsiflex the toes of the forefoot of the patient an angle of between 30 to 50 to the plane of the foot (2). A surgical foot orthotic (12) is formed by the steps of disposing a patient's foot (2) or both feet in a weight bearing neutral position and dorsiflexing the forefoot or forefeet of the patient such that patient's foot (2) or feet are in or towards the Windlass configuration. A first orthotic (5) correcting the stance of the patient in the weight bearing position with dorsiflexed forefoot is formed and this is scanned to form an electronic image of the corrective load bearing surface. The electronic image is modified to include one or more guide apertures or cut-outs (9) and a surgical corrected weight-bearing orthotic from the modified electronic image is 3-D printed with the one or more guide apertures or cut-outs.

The ankle foot orthosis solves a problem of a poor adaptation to a user's foot (3) and the related discomfort. It provides for simultaneous correction of several symptoms in the foot and ankle areas. It is completely produced from a uniform material, the thickness and shape of which change depending on user's specific needs. It is designed in such a way that it does not intervene with other functions of a user's foot. It is manufactured by preparing a 3D model of a user's foot when placed in a physiologically correct static position, by modelling the ankle foot orthosis directly to a 3D model of the foot (3), by 3D printing from preferably a photopolymer, and by adequate post-processing. Due to its minimalistic design, the user can wear the orthosis in a shoe of his appropriate foot size.

A training system includes: an inverted-pendulum mobile body including a drive wheel and a riding portion on which a rider rides in a standing position; a first detecting unit configured to detect a driving torque that is applied to the drive wheel to maintain the inverted-pendulum mobile body in an inverted state; a second detecting unit configured to detect a load applied by the rider to an assisting support portion configured to assist the rider in maintaining a balance; and an output unit configured to generate torque information about an ankle-joint torque applied by the rider to the riding portion, based on the driving torque detected by the first detecting unit and the load detected by the second detecting unit, and configured to output the torque information.

An ankle coil is disclosed that includes a first coil portion and a second coil portion. The first coil portion has a first channel that is hollow and extends in a first extension direction. The second coil portion has a second channel that is hollow and extends in a second extension direction intersecting with the first extension direction. The second coil portion is rotatably arranged on the first coil portion, with an axis of rotation perpendicular to both the first extension direction and the second extension direction, and notches are provided at a joint between the first coil portion and the second coil portion. The ankle coil provided in the present disclosure in use allows an ankle to be placed in a naturally relaxed state, and can be snugly fitted with the foot, so that the comfort of a user is improved while ensuring the imaging quality.

A system for determining the alignment measurement of the foot and ankle is disclosed. The system uses data representative of a three dimensional scanned image of a patient's foot and ankle while the patient was applying weight on the foot. Next the system detects the three dimensional coordinates associated with at least three predetermined landmarks on the patent's foot in the scanned image. A ground plane is determined using the predetermined landmarks. A center of a talar dome is determined in the scanned data. An ankle offset lever arm id determined from the set of landmarks and center of the talar dome.
