The problem to be solved is to provide a new method and system for appropriately detecting a joint state from an acoustic of a joint. The present method comprises the step of obtaining, using a bio-acoustic sensor, an acoustic signal emitted by a joint during a time period that at least includes a first motion period wherein the joint changes from a first state to a second state, a pause period of the joint and a second motion period wherein the joint changes from the second state to the first state, the step of converting the obtained acoustic signal into time trend data that at least shows a relationship between an acoustic signal intensity and time, and the step of setting, from the time trend data, a basic threshold value regarding the acoustic signal intensity to calculate first acoustic information based on the basic threshold value, characterized in that the first acoustic information is an indicator of the joint state.

A method of measuring muscular fitness of a user using a wearable device includes determining a target resistance profile for a target movement to be performed by the user wearing the wearable device to measure muscular fitness, controlling a motor driver circuit of the wearable device based on the target resistance profile to control a resistance force to be provided to the user, measuring state information of an actual movement performed by the user under the resistance force, and measuring the muscular fitness of the user based on the state information.

Various embodiments disclosed relate to a method for producing an implant model and associated systems. The method can include receiving patient specific data, producing a preliminary implant model based on the received patient specific data, running a simulation on the preliminary implant model to produce a revised implant model with a range of motion zone using the patient specific kinematics, optimizing the preliminary implant model with a dynamic simulation to determine a cup anteversion angle, analyzing the revised implant model for spino-pelvic risk, and outputting the implant model.

An instrument for establishing orientation of a pelvic prosthesis comprises a hub, a first arm attached to and extending from the hub, and a second arm attached to and extending from the hub. The first and second arms define a nominal plane of the apparatus, and may extend from the hub at an angle relative to each other. Distances between the first and second legs and between the first and third legs are adjustable. The first, second, and third legs have tips, and the tips of the first, second, and third legs define a plane having a predefined geometric relationship to the nominal plane of the apparatus.

An apparatus for performing a remote test of range of motion of a person operating a user device includes a transceiver, a processor, and a display. The transceiver is configured to transmit a link to the user device and to receive motion data from the user device. The processor is configured to calculate in real time, based on the motion data, the position of the user device to enable real-time display to a test provider of the performance of the test and to determine in real time the quality of the test. The display is configured to show in real time a continuous indication of the performance of the test and quality results of the test. A method for performing a remote test of range of motion of a person operating a user device is also described and claimed.

A device and a method for identifying a motion pattern of a person that allow suitable feedback about an identified motion pattern to be produced in real time, to address the disadvantage that there is no provision for direct feedback to the person in the event of abnormal behavior being detected. This is achieved by virtue of a device for identifying a motion pattern of a person having at least one sensor for capturing motion parameters and at least one evaluation unit, which is couplable to the at least one sensor, for evaluating the motion parameters and for producing a motion pattern.

An ECU device which estimates a length of a lower limb of a seated person who is seated in a vehicle seat is shown. The ECU device includes the following. A thigh angle information obtainer obtains information regarding a thigh angle of the seated person. A back knee angle information obtainer obtains information regarding a back knee angle of the seated person. An estimator estimates the length of the lower limb of the seated person based on the information regarding the thigh angle obtained by the thigh angle information obtainer and information regarding the back knee angle obtained by the back knee angle information obtainer.

The present invention relates to a computer-implemented system and method for preventing users from bending their necks too far forward or past thirty degrees away from vertical during viewing of a handheld electronic device. The system uses a computer-implemented application installed in the device that determines flexion of the user's neck and compares with a threshold to determine a ‘tech neck’ condition. The application generates an alert displayed on the screen of the device to indicate the ‘tech neck’ condition and further, can pause or hang the display when the ‘tech neck’ condition is continued to be determined. The system and method assist in preventing injuries, strains and disabilities to both children and adults that use electronic devices for extended periods of time.

A method for automatically determining spine deformation from an image showing a number of vertebrae of the spine, comprises: detecting center points of the number of vertebrae shown in the image; constructing a center line based on the center points; computing a local tilt at points along the center line; determining positive and negative tilt-maxima of the local tilt and selecting two reference vertebrae having center points closest to the positive and negative tilt-maxima; segmenting an upper endplate of the cranial reference vertebra; segmenting a lower endplate of the caudal reference vertebra; computing an angle between the upper endplate and the lower endplate; and outputting the angle.

The present invention relates generally to the field of orthopedics, and more particularly to a pelvic referencing guide and methods of using the guide in orthopaedic surgery, specifically total hip arthroplasty.
