A method of generating a correction plan for a knee of a patient includes obtaining a ratio of reference bone density to reference ligament tension in a reference population. A bone of the knee of the patient may be imaged. From the image of the bone, a first dataset may be determined including at least one site of ligament attachment and existing dwell points of a medial femoral condyle and lateral femoral condyle of the patient on a tibia of the patient. Desired positions of contact in three dimensions of the femoral condyles of the patient with the tibia of the patient may be obtained by determining a relationship in which a ratio of bone density to ligament tension of the patient is substantially equal to the ratio of reference bone density to reference ligament tension.

The embodiments of the present disclosure are capable of capturing a user's movement using inertial measurement units (IMUs) that are embedded in, or otherwise attached to, clothing. In one embodiment, a wearable system for capturing a user's bodily movements includes a wearable item mechanically coupled to an inertial measurement unit (IMU). The wearable item, when worn by a user, positions the IMU proximate to a body part of the user. The system further includes a processor communicatively coupled to the IMU and configured to receive the sensor data from the IMU, generate movement data based on the sensor data, and transmit the movement data to a device. The device includes a processor configured to receive the movement data, generate a kinematic chain model of the user, the model representing positions and orientations of one or more joints of the user at a given time, modify the kinematic chain model based on the movement data, determine a force experienced at a joint of the user using the kinematic chain model, and record the kinematic chain model and the force over a period of time.

According to an aspect, there is provided a grip measurement system (300) comprising a door handle (100') comprising a first sensor (108) configured to measure a first parameter indicative of an amount of a part of a user’s hand in contact with the first sensor; a storage device (304); and a processor (302) configured to estimate, based on the measured first parameter, a force applied onto the first sensor by the part of the user’s hand; and store an indication of the estimated force in the storage device.

Methods, apparatuses, systems, and implementations for inductive heating of a foreign metallic implant are disclosed. A foreign metallic implant may be heated via AMF pulses to ensure that the surface of the foreign metallic implant heats in a uniform manner. As the surface temperature of the foreign metallic implant rises, acoustic signatures may be detected by acoustic sensors that may indicate that tissue may be heating to an undesirable level approaching a boiling point. Once these acoustic signatures are detected, the AMF pulses may be shut off for a time period to allow the surface temperature of the implant to cool before applying additional AMF pulses. In this manner, the surface temperature of a foreign metallic implant may be uniformly heated to a temperature adequate to treat bacterial biofilm buildup on the surface of the foreign metallic implant without damaging surrounding tissue. The AMF pulse treatment can be combined with an antibacterial/antimicrobial treatment regimen to reduce the time and/or antibacterial dosage amount needed to remove the biofilm from the metallic implant.

Action recognition methods are disclosed. An embodiment of the methods includes: identifying a video that comprises images of a human body to be processed; identifying at least one image to be processed, wherein the at least one image is at least one of an optical flow image generated based on a plurality of frames of images in the video, or a composite image of one or more frames of images in the video; performing convolution on the at least one image to obtain a plurality of eigenvectors, wherein the plurality of eigenvectors indicate a plurality of features of different locations in the at least one image; determining a weight coefficient set of each of a plurality of human joints of the human body based on the plurality of eigenvectors, wherein the weight coefficient set comprises a weight coefficient of each of the plurality of eigenvectors for the human joint; weighting the plurality of eigenvectors based on the weight coefficient set to obtain an action feature of each of the plurality of human joints; determining an action feature of the human body based on the action feature of each of the human joints; and determining an action type of the human body based on the action feature of the human body.

A system for monitoring the state of a disease or the state of a person using a biomarker, the system comprising: a motion data obtaining unit configured to obtain from at least one motion sensor motion data from a person having the disease, a generating unit configured to generate a value of the biomarker of the disease based on the obtained motion data, and an assessing unit configured to assess the value of the biomarker of the disease and, based on the assessment, to output information related to the state of the disease or state of a person

A medical implant includes a sensor that detects electromagnetic waves; and a data transmission unit that can wirelessly transmit data supplied by the sensor to a receiving unit.

Provided is a biological examination apparatus and a biological information analysis method capable of quickly grasping a two-dimensional motions of the up-down and front-back directions of the thyroid cartilage and the lingual bone accompanied by a swallowing sound as swallowing dynamics by a non-invasive examination. In the biological examination apparatus of the present invention, an up-down motion component associated with an up-down motion of the thyroid cartilage and a front-back motion component associated with a front-back motion of the thyroid cartilage are extracted from a fitting result obtained by fitting a model function modeling a swallowing motion to distance information based on detection data detected by a larynx portion displacement detector, and a two-dimensional trajectory data indicating behavior trajectories of an up-down direction and a front-back direction of the thyroid cartilage is generated based on the extracted up-down motion component and the extracted front-back motion component.
