Systems, devices, and methods for tracking and determining the motion of a cardiac implant is disclosed. The motion of the implant is determined by transmitting acoustic energy to a tissue location using an acoustic controller-transmitter comprising an array of acoustic transducers; wherein the implant is configured to convert the transmitted acoustic energy to electrical energy; and the tracking is achieved by determining the electrical energy delivered to the tissue throughout one or more cardiac cycles in order to create a motion profile of the cardiac implant.

A mirror therapy device includes a first positioning assembly, a second positioning assembly and a transmission assembly connecting the first and second positioning assemblies. The first and second positioning assemblies are arranged in opposition to each other in such a manner that both are able to reciprocate. The first positioning assembly is configured for positioning of a healthy limb of a patient, and the second positioning assembly is configured for positioning of an affected limb of the patient. The transmission assembly is configured for power transmission between the first and second positioning assemblies so that the second positioning assembly moves in synchronization with the first positioning assembly under the action of the transmission assembly. A mirror therapy system includes the mirror therapy device and a display device. The mirror therapy system enables the healthy limb to drive movement of the affected limb to allow the affected limb to repeat the same movements as the healthy limb, thus establishing neural connections for synchronous vision, motor perception and proprioception of the patient's healthy and affected sides and better stimulating nerve recovery of the patient.

Systems and methods are described for the monitoring of patient motion via the detection of changes in capacitance, as measured using a capacitance position sensing electrode array. The changes in capacitance may be processed to determine a corresponding positional offset, for example, using a calibration data set relating capacitance to offset for each electrode of the array. The detected positional offset may be employed to provide feedback to a surgeon or operator of a medical device, or directly to the medical device for the control thereof. A medical procedure may be interrupted when the positional offset is detected to exceed a threshold. Alternatively, the detected positional offset may be employed to manually or automatically reconfigure a medical device to compensate for the detected change in position. Various configurations of capacitive position sensing devices are disclosed, including embodiment in incorporating capacitive sensing electrodes with a mask or other support structure.
