SPINAL CORD INJURY THERAPY BASED ON EVOKED COMPOUND ACTION POTENTIALS

Devices, systems, and techniques for controlling electrical stimulation therapy are described. In one example, a system is configured to deliver, via a first electrode combination, a first stimulation pulse to a portion of a spinal cord of a patient located caudally of a spinal cord injury location of the spinal cord of the patient; sense, via a second electrode combination, an evoked compound action potential (ECAP) signal elicited by the first stimulation pulse; identify, by processing circuitry, a characteristic of the ECAP signal; determine, by the processing circuitry and based on the characteristic of the ECAP signal, a therapy parameter value that at least partially defines a second stimulation pulse; and deliver the second stimulation pulse according to the determined therapy parameter value.
