The present invention relates to a system and method for acquiring and analyzing physiological data from a user. The system includes a plurality of interconnected devices, which may communicate sensor data to a personal mobile electronic device. Each interconnected device includes at least one sensor to acquire physiological data. In addition, at least one sensor is operably connected to the body of the user. Further, the interconnected biometric devices may be implanted medical devices and/or wearable electronic devices. The personal mobile electronic device is wirelessly connected to each of the plurality of interconnected biometric devices. In addition, the personal mobile electronic device is configured to receive and analyze physiological data acquired by each of the plurality of interconnected devices and to compute the difference between the values of the same physiological parameter measured at a different location of the users body.

The present invention, herein is a method and apparatus that significantly limits the effect of high frequency (“HF”) interferences on acquired electro-physiological signals, such as the EEG and EMG. Preferably, this method comprises of two separate electronic circuitries and steps or electronics for processing the signals. One circuit is used to block the transmission of HF interferences to the instrumentation amplifiers. It is comprised of a front-end active filter, a low frequency electromagnetic interference (“EMI”) shield, and an isolation barrier interface which isolates the patient from earth ground. The second circuit is used to measure the difference in potential between the two isolated sides of the isolation barrier. This so-called “cross-barrier” voltage is directly representative of the interference level that the instrumentation amplifier is subjected to. This circuit is used to confirm that the acquired signals are not corrupted by the interference.

A method for diagnosing a joint condition includes in one embodiment: creating a 3d model of the patient specific bone; registering the patient's bone with the bone model; tracking the motion of the patient specific bone through a range of motion; selecting a database including empirical mathematical descriptions of the motion of a plurality actual bones through ranges of motion; and comparing the motion of the patient specific bone to the database.

A stationary dilator has one or more electrodes in the distal region that are rotatable around the longitudinal axis of the dilator. The one or more electrodes are operable to deliver electrical stimulation signals to tissue through which the dilator is passed. The stimulation signals can be used for determining nerve directionality and optionally nerve proximity during surgical procedures involving the presence of neural structures.
