Abstract
A system, method, and apparatus for treating a medical condition by applying transcutaneous electrical stimulation to a target peripheral nerve of a subject. Electrical stimulation is applied to the peripheral nerve via a stimulation electrode pattern under closed-loop control in which EMG responses are monitored and used to adjust stimulation parameters. In response to detecting an unacceptable recording, electrical stimulation is applied to the peripheral nerve under open-loop control.
Claims26
A method for treating a medical condition by applying transcutaneous electrical stimulation to a target peripheral nerve of a subject, comprising:
- positioning a plurality of stimulation electrodes on a skin surface proximate the targeted peripheral nerve, the stimulation electrodes being spaced from each other in a predetermined configuration;
- positioning one or more recording electrodes on a skin surface remote from the stimulation electrodes at a location where electromyogram (EMG) responses to electrical stimulation of the targeted peripheral nerve can be detected;
- selecting a stimulation electrode pattern from a pattern list;
- and
- applying electrical stimulation pulses via the selected stimulation electrode pattern, wherein the pattern list being determined by:
- a) identifying a set of predetermined stimulation electrode patterns, each stimulation electrode pattern identifying which of the plurality of stimulation electrodes will apply the electrical stimulation pulses, and each stimulation electrode pattern having associated with it stimulation parameters according to which it applies stimulation pulses;
- b) selecting a stimulation electrode pattern from the set of predetermined stimulation electrode patterns;
- c) generating a stimulation pulse using the selected stimulation electrode pattern according to its associated stimulation parameters;
- d) determining via the recording electrodes whether the stimulation pulse using the selected stimulation electrode pattern elicited an EMG response;
- e) adding the selected stimulation electrode pattern to the pattern list in response to detecting an EMG response;
- f) omitting the selected stimulation electrode pattern from the pattern list in response to not detecting an EMG response;
- and
- repeating steps b) through f) for each stimulation electrode pattern in the set of predetermined stimulation electrode patterns to complete the pattern list.
A system for treating overactive bladder by applying transcutaneous electrical stimulation to the tibial nerve of a subject, comprising:
- a plurality of electrical stimulation electrodes, the stimulation electrodes being spaced from each other in a predetermined configuration on a skin surface proximate the tibial nerve;
- one or more recording electrodes positioned on a skin surface remote from the stimulation electrodes at a location where electromyogram (EMG) responses to electrical stimulation of the tibial nerve can be detected;
- a structure for supporting the stimulation electrodes and the recording electrodes spaced apart from each other in their respective positions;
- and
- a control unit for controlling the operation of the stimulation electrodes and the recording electrodes, wherein the control unit is configured to:
- select a stimulation electrode pattern from a pattern list;
- and
- apply electrical stimulation pulses via the selected stimulation electrode pattern, wherein the pattern list is determined by:
- a) identify a set of predetermined stimulation electrode patterns, each stimulation electrode pattern identifying which of the plurality of stimulation electrodes will apply the electrical stimulation pulses, and each stimulation electrode pattern having associated with it stimulation parameters according to which it applies stimulation pulses;
- b) select a stimulation electrode pattern from the set of predetermined stimulation electrode patterns;
- c) generate a stimulation pulse using the selected stimulation electrode pattern according to its associated stimulation parameters;
- d) determine via the recording electrodes whether the stimulation pulse using the selected stimulation electrode pattern elicited an EMG response;
- e) add the selected stimulation electrode pattern to the pattern list in response to detecting an EMG response;
- f) omit the selected stimulation electrode pattern from the pattern list in response to not detecting an EMG response;
- and
- repeat steps b) through f) for each stimulation electrode pattern in the set of predetermined stimulation electrode patterns to complete the pattern list.
