A method or system for generating a clinical effects map for electrical stimulation includes receiving stimulation parameters and at least one clinical response for each of a plurality of stimulation instances; for each of the stimulation instances, determining a radius of a stimulation field according to the stimulation parameters for the stimulation instance; generating the clinical effects map using the at least one clinical response and the stimulation parameters for each of the stimulation instances, wherein, for each of the stimulation instances, the at least one clinical response for the stimulation instance is assigned to the radius of the stimulation field determined for the stimulation instance; and displaying the clinical effects map.

An interactive representation of electrostimulation electrodes or vectors can be provided, such as for configuring combinations of electrostimulation electrodes. In an example, electrodes or test parameters can be presented graphically or in a table. A user interface can be configured to receive user-input designating electrode combinations or vectors for test or for use in programming an implantable or ambulatory medical device. The interface can be used to indicate suggested electrode combinations or vectors in response to a first selection of an electrode. Tests can be performed on electrode combinations and vectors, and the results of the tests can be presented to a user using the interactive representation. In an example, test results can be analyzed by a processor and optionally used to program an implantable or ambulatory medical device.

A computer-assisted stimulation programming of an implantable medical device is performed. A perception threshold is determined for a plurality of contacts on a lead configured to be implanted inside a patient. The perception threshold is determined by automatically performing a first sweep of the plurality of contacts and automatically performing a second sweep of a stimulation parameter. A paresthesia coverage provided by the plurality of contacts is determined by automatically performing a third sweep of the plurality of contacts and automatically performing a fourth sweep of the stimulation parameter. The fourth sweep is performed based on the determined perception thresholds. The first sweep, the second sweep, the third sweep, and the fourth sweep are performed without needing a manual input from a human user. A subset of the contacts corresponding to the paresthesia coverage is selected. In response to user input, stimulation programming is performed using the subset of contacts.

Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue.

A first fraction of an electrical stimulation is allocated to a first electrode. In response to user input, the first fraction of the electrical stimulation is fixed to the first electrode such that the first fraction is user-adjustable but cannot be automatically changed. In response to the first fraction being fixed to the first electrode, a respective second fraction of the electrical stimulation is automatically allocated to a plurality of second electrodes. The second fraction is a function of the first fraction and a total number of the second electrodes. Thereafter, a new electrode is added to, or deleting from, the second electrodes, while the first fraction is still fixed to the first electrode. The respective second fractions are automatically adjusted in response to the adding or the deleting, without affecting the first fraction of the electrical stimulation that has been fixed to the first electrode.

A device to make multiple, simultaneous measurements of electrical activity on neural, muscular and other animal cells. The invention discloses multiple electrodes at fixed position on a supporting structure and multiple wires to connect the electrodes to one or more measuring devices. The electrodes are preferentially closed spaced, to allow for small spatial discrimination between measurement points. The electrodes and the wires are selected by binary addresses. The device is also capable of injecting electrical stimulation using electrodes not in use for measurements. An injected electrical stimulation at a first location may be created to measure the effect of a well-known event at another location or locations, near or far away.

Systems and methods are disclosed for conducting spinal cord stimulation or other neurostimulation and sensing evoked compound action potential (ECAP) signals. The sensed signals may be processed to isolate ECAP features from noise and/or interfering signals. The isolated ECAP features may be used to control neurostimulation therapy for the patient and/or guide an implant procedure.

Disclosed is a system for stimulation of a subject. The stimulation may be to provide therapy to treat the subject. Stimulation may be of selected muscle groups and/or portions.

This specification describes systems, methods, devices, and other techniques for activating muscle groups in a mammal using an implantable epidural electrical stimulation (EES) system, and for using spinal landmarks to determine implant locations for an EES probe. In some aspects, a first set of electrodes of an EES system is provided at a first set of locations on the dura mater of a spine of a mammal, the first set of locations on the dura mater corresponding to a first muscle group of the mammal, a second set of electrodes is provided at a second set of locations on the dura mater of the spine of the mammal, the second set of locations on the dura mater corresponding to a second muscle group of the mammal, and the first and second sets of locations on the dura mater are stimulated by electrically energizing the first and second sets of electrodes.

Feedback regarding electrical stimulation is provided to a patient. Electrical stimulation is applied to the patient. The electrical stimulation is applied by varying an electrical stimulation parameter. A signal is communicated to the patient via an electronic device. The signal is correlated with the electrical stimulation parameter such that the signal varies in association with the varying of the electrical stimulation parameter. The communicating is performed while the electrical stimulation is applied. Feedback is received from the patient in response to the electrical stimulation. Based on the received feedback from the patient, the electrical stimulation is adjusted.
