Controlling electrical stimulation based on a sensed stimulation signal

A method comprising:

• delivering, by stimulation generation circuitry, a first stimulation pulse to a patient;
• sensing, by sensing circuitry, the first stimulation pulse;
• determining, by processing circuitry, that a value of a characteristic of the sensed first stimulation pulse exceeds a target stimulation pulse value;
• and
• responsive to determining that the value of the characteristic of the sensed first stimulation pulse exceeds the target stimulation pulse value, changing, by the processing circuitry, a first value of a parameter to a second value of the parameter that at least partially defines a second stimulation pulse deliverable by the stimulation generation circuitry after the first stimulation pulse was sensed.

A medical device comprising:

• stimulation generation circuitry configured to deliver a first stimulation pulse to a patient;
• sensing circuitry configured to sense a residual phase of the first stimulation pulse;
• and
• processing circuitry configured to:
• determine that a value of a characteristic of the sensed residual phase of the first stimulation pulse exceeds a target residual phase value;
• and
• responsive to determining that the value of the characteristic of the sensed residual phase exceeds the target residual phase value, change a first value of a parameter to a second value of the parameter that at least partially defines a second stimulation pulse deliverable by the stimulation generation circuitry after the residual phase of the first stimulation pulse was sensed.
