The image includes the target area of the body part and the first and second members. The first member indicates a first axis of the body part, and the second member indicates a second axis of the body part.

Systems and methods for systems and platforms that receive data from and send data to wearable devices, receive data from environmental sensors, and visualization which collectively creates a kinematic chain to allow for input from individuals, groups, third party information and interfaces with historical data as well as predictive modeling systems. Systems that include data from interoperable wearables in conjunction with one or more sensors and measuring devices may be used. Furthermore, the interoperability of one or more sensors and communication modules could be networked with one or more physical entities and objects creating an interactive communication network.

In addition, the platforms and networks could also include real-time biological interoperability based on various synchronized and/or asynchronized data inputs, information and media.

A sensing system for tracking a center of rotation of a joint can include a computer system including processing circuitry configured to perform operations including: retrieve a first data set collected by a sensor device configured to be implanted into a patient in a fixed location on or within a first bone of the joint, the sensor device configured to collect data associated with movement of the first bone of the joint at a first time, retrieve a second data set collected by the sensor device at a second time subsequent to the first time; analyze the first and the second data sets to calculate first and second center of rotation locations; and compare the first and second center of rotation locations to track migration in the center of rotation of the joint over time.

A sensing device including a sensor, a triggering mechanism is provided. The sensing device is attachable to a covering positioned in contact with a body such that the triggering mechanism extends between first and second segments of the body. Movement of at least one of the first and second segments activates the triggering mechanism to provide an input to the sensor, actuating the sensor to generate an output defining at least one measurement of the movement. The measurement may be one or more of rotation, translation, velocity, acceleration, and joint angle. An intermediate mechanism may be interposed between the triggering mechanism and the sensor. The sensing device may include a means to process or record measurements corresponding to movement. A system and method of measuring the movement is also provided.
