    Abstract: Devices, systems, and techniques are described for identifying stimulation parameter values based on electrical stimulation that induces dyskinesia for the patient. For example, a method may include controlling, by processing circuitry, a medical device to deliver electrical stimulation to a portion of a brain of a patient, receiving, by the processing circuitry, information representative of an electrical signal sensed from the brain after delivery of the electrical stimulation, determining, by the processing circuitry and from the information representative of the electrical signal, a peak in a spectral power of the electrical signal at a second frequency lower than a first frequency of the electrical stimulation, and responsive to determining the peak in the spectral power of the electrical signal at the second frequency, performing, by the processing circuitry, an action.

    Abstract: Systems, devices, and techniques for adjusting electrical stimulation based on a posture state of a patient are described. For example, processing circuitry is configured to receive an input from a user adjusting an informed stimulation parameter that at least partially defines a plurality of informed pulses, determine a ratio of a first value of an informed stimulation parameter to a first value of a control stimulation parameter that at least partially defines a plurality of control pulses, change, according to the input, the first value of the informed stimulation parameter to a second value of the informed stimulation parameter, and change, based on the input and the ratio, the first value of the control stimulation parameter to a second value of the control stimulation parameter. The processing circuitry' can then control delivery of the adjusted control pulses and informed pulses.

    Abstract: Systems, devices, and techniques are described for analyzing evoked compound action potentials (ECAP) signals to assess the effect of a delivered electrical stimulation signal. In one example, a system includes a stimulation generator configured to deliver a stimulation pulse to a patient, sensing circuitry configured to sense an evoked compound action potential (ECAP) signal evoked from the stimulation pulse, and processing circuitry. The processing circuitry may be configured to determine a maximum value of a derivative of the ECAP signal, determine a minimum value of the derivative of the ECAP signal, determine, based on the maximum value of the derivative and the minimum value of the derivative, a characteristic value of the ECAP signal, and determine, based on the characteristic value of the ECAP signal, at least one parameter value at least partially defining electrical stimulation therapy to be delivered to the patient.
