1. A wireless physiological monitoring system for measuring physiological signals from a patient, comprising:

  • a monitoring device, external to the patient, having a first transceiver;

    at least one wireless sensor disposed on a measurement site on the patient for measuring a physiological signal, the at least one wireless sensor having a second transceiver for transmitting a corresponding wireless physiological signal to the first transceiver;

    at least one wireless diagnostic stimulator having a third transceiver, the at least one wireless stimulator being adapted to provide a stimulation current to the patient in response to at least one of a command signal transmitted by the first transceiver of the monitoring device and manual actuation;

    wherein the at least one wireless sensor includes a wireless adapter comprising;

    the second transceiver;

    a measurement module having an active conductor and a reference conductor for receiving voltages used to produce a differential voltage measurement indicative of the physiological signal, the measurement module further including a common conductor for receiving another voltage for removing common mode voltage from the differential measurement; and

    a wireless needle assembly comprising the measurement module; and

    wherein the second transceiver transmits the differential measurement as the wireless physiological signal.
