Method and apparatus for electrical stimulation therapy
Energy emitting systems are provided which include an adjustable conductive coil configured to generate a magnetic or electromagnetic field focused on a target nerve. The coil includes a central aperture which may be adjustable between a first configuration and a second configuration having a radius greater than the radius of the first configuration. The adjustable or movable nature of the coil allows the conductive coil to conform to, accommodate, or be positioned on a particular anatomical structure of a patient to position the coil in proximity to the underlying target nerve. In certain embodiments, methods of magnetic induction therapy are provided which include positioning a conductive coil relative to a portion of a patient's body by adjusting the central aperture of the coil such that the coil may conform to, accommodate or be positioned on the portion of the patient's body in proximity to the underlying target nerve.
1. A method of performing electrical stimulation therapy to treat urinary incontinence in a patient, comprising:
positioning a first portion of a patient's body relative to a microneedle electrode wherein the microneedle electrode is positioned on the skin of a patient;
passing a current through the microneedle electrode to deliver electrical energy through the skin such that the electrical energy stimulates the posterior tibial nerve or a branch thereof;
placing at least one sensor on a second portion of the body of the patient;
detecting stimulation of the posterior tibial nerve or a branch thereof utilizing the at least one sensor by detecting a signal that an afferent nerve has been stimulated;
receiving a signal from the sensor indicative of stimulation of the posterior tibial nerve or a branch thereof; and
whereby the detection is used in modulating the current via a controller in communication with the microneedle electrode to provide an optimal dosage of therapy to treat urinary incontinence.
2. The method of claim 1 wherein passing a current comprises passing the current through a plurality of microneedles.
3. The method of claim 1 wherein modulating comprises adjusting an amplitude, frequency, direction of the electrical stimulus, or firing sequence of the microneedle electrode.
4. The method of claim 1 wherein modulating comprises adjusting a position of the microneedle electrode relative to the first portion of the patient's body to re-focus the electrical energy on the target nerve.
5. The method of claim 1 wherein the sensor is comprised of a microneedle sensor applied to a skin surface.
