Delivery of electrical stimulation to the substantia nigra and the subthalamic nucleus of a brain of a patient are independently controlled in order to treat sleep and movement disorders. Electrical stimulation of the subthalamic nucleus may be effective in treating symptoms associated with a movement disorder, and electrical stimulation of the substantia nigra may be effective in treating symptoms associated with a sleep disorder. During a sleep state of the patient, a sleep stage of the patient may be determined, and an electrical stimulation device may be controlled based on the determined sleep stage. Electrical stimulation of the substantia nigra and subthalamic nucleus may be delivered at substantially the same time or at different times.

In general, the disclosure is directed to devices, systems, and techniques for delivering electrical stimulation to a patient with varying pulse frequencies within each burst of pulses. The pulse frequency variation within each burst of pulses may be between approximately 20 Hz and 40 Hz. In some examples, the pulse frequency may be increased, decreased, or polynomially varied within each burst. In other examples, the frequency of intrinsic nerve impulses may be detected and used to deliver pulses with the detected frequency or an inverse of the detected frequency. Electrical stimulation therapy with intra-burst pulse frequency variation may alleviate bladder dysfunction, bowel dysfunction, pain or other disorders.

A medical device is configured to deliver a first stimulation therapy to a patient, and, upon detecting a trigger event, deliver a second stimulation therapy to the patient. In some examples, the first stimulation therapy includes bilateral stimulation in which stimulation is delivered at different times to two lateral sides of the patient and the second stimulation therapy includes substantially simultaneous bilateral stimulation therapy to two lateral sides of the patient. In some examples, the second stimulation therapy may elicit a stronger inhibitory physiological response related to incontinence (e.g., inhibition of bladder contractions) than the first stimulation therapy. The trigger event may include, for example, any one or more of detection of a physiological condition indicative of an increased possibility of an involuntary voiding event or an imminent involuntary voiding event, input from the patient, a predetermined time of day, or expiration of a timer.

In some examples, a medical device delivers a first electrical stimulation therapy to a patient, and, upon detecting a trigger event, delivers a second electrical stimulation therapy to the patient. In some examples, the first stimulation therapy includes unilateral stimulation or stimulation delivered to both lateral sides of the patient at different times at a stimulation intensity lower than, equal to, or greater than a threshold intensity level for the patient, or bilateral stimulation delivered substantially simultaneously to both lateral sides of the patient, where one lateral side of the patient receives stimulation at an intensity level that is lower than the threshold intensity level and the other lateral side receives stimulation at an intensity level that is greater than or equal to the threshold intensity level. The second stimulation therapy may include substantially simultaneous bilateral stimulation therapy at an intensity level that at or above the threshold intensity level.

A medical system may include a control module and a therapy delivery module configured to generate and deliver electrical stimulation therapy to a patient. The control module may be configured to control the therapy delivery module to deliver electrical stimulation at a first stimulation intensity for a first time period, to deliver electrical stimulation at a second stimulation intensity for a second time period immediately following the first time period, and to deliver electrical stimulation at the first stimulation intensity for a third time period immediately following the second time period. The second stimulation intensity may be less than the first stimulation intensity. The electrical stimulation may elicit a first inhibitory physiological response during the first time period and a second inhibitory physiological response during the second time period. The second inhibitory physiological response may be greater than the first inhibitory physiological response.

In some examples, electrical stimulation is delivered to a patient such that selective termination of the stimulation causes a therapeutic effect in the patient after termination of the electrical stimulation to the patient. The electrical stimulation may be insufficient to produce a desired therapeutic effect in the patient during stimulation, but sufficient to induce a post-stimulation desired therapeutic effect following termination of the stimulation. In some examples, the electrical stimulation may be sub-threshold electrical stimulation. In some examples, the desired therapeutic effect may alleviate bladder dysfunction, bowel dysfunction, or other disorders. The stimulation may be selectively terminated in response to one or more therapy trigger events to induce the post-stimulation therapeutic effect.

In one example, a system includes a therapy module and a processor. The processor detects a voiding event of a patient and controls the therapy module to deliver electrical stimulation to the patient at a first intensity level for a period of time in response to the detection of the voiding event. Immediately following the period of time, the processor controls the therapy module to increase intensity of the electrical stimulation from the first intensity level to a second intensity level before a subsequent voiding event of the patient by at least controlling the therapy module to deliver stimulation to the patient at a plurality of intermediate intensity levels between the first and second intensity levels prior to delivering stimulation to the patient at the second intensity level following the detection of the voiding event.

Devices, systems, and techniques for controlling electrical stimulation therapy are described. In one example, a system may include processing circuitry configured to control a medical device to deliver a first electrical stimulation according to a first value of a first stimulation parameter of the plurality of stimulation parameters and a first value of a second parameter of the plurality of stimulation parameters, receive an input representative of an efficacy of the first electrical stimulation delivered to the patient according to the first value of the first stimulation parameter and the first value of the second parameter, select, based on the input and the relationship between the plurality of stimulation parameters, a second value of at least one of the first stimulation parameter or the second stimulation parameter, and control the medical device to deliver a second electrical stimulation according to the second value.
