The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

A method of neurostimulation may include delivering an electrical signal to a plurality of electrodes connected to a patient. The electrical signal may include an amplitude and a carrier frequency. The method may include modulating the electrical signal based on an audio waveform. In some embodiments, the modulating may include modulating at least one of the amplitude and the carrier frequency based on the audio waveform to modulate the electrical signal.

Supplying a transcranial alternating current neurostimulation signal to a human brain is shown. A first signal is supplied at a first frequency to said human brain, in combination with a second signal at a second frequency. A third signal at a third frequency is created due to interference between the first signal and the second signal.

The invention consists of a device to evaluate hemodynamic response generated by the spinal cord in response to a suprasensorial stimulus applied to a peripheral nerve (medium or posterior tibial) by the use of functional near-infrared spectroscopy (fNIRS). The device consists of 3 main components, an electrical stimulator, an optical recording unit and a signal processing and control module. The device allows non-invasive, comfortable, harmless, portable, home-based, and low-cost evaluation of changes in local hemodynamic parameters in response to neuronal activation of the spinal cord by electrical stimulation of a peripheral nerve. The invention also includes a corresponding method of using the device and monitoring the spinal function.

A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.
