![]() In accordance with some examples of the disclosure, one or more particular stimulation locations on the dorsal columns may be determined by delivering electrical stimulation to a dorsal root and/or peripheral nerve and sensing the signals evoked by the electrical stimulation at one or more locations on the dorsal columns. In some cases, a patient may be partially sedated during this process, which may influence the reliability of the feedback elicited from the patient. ![]() The patient feedback may include feedback relating to efficacy of the stimulation in providing pain relief, as well as possible side effects which could undermine efficacy. During the process, the clinician may deliver electrical stimulation to a patient at the various locations on one or both of the dorsal columns and evaluate the efficacy of the stimulation delivered to the respective locations based on patient feedback. In some cases, a clinician may use a trial-and-error process to identify a particular location on the dorsal columns for stimulation during which the clinician systematically relocates one or more electrodes to points along the dorsal columns and/or adjusts stimulation electrode combinations. However, unlike peripheral nerve stimulation or dorsal root stimulation, it may be a relatively difficult and often time consuming process to identify one or more particular stimulation locations on the one or both dorsal columns associated with pain experienced by a patient. In other examples, an IMD may deliver electrical stimulation therapy to one or both of the left and right dorsal columns of a patient to treat a patient condition such as pain. In some examples, the dorsal column location at which the sensed evoked signal exhibited the largest signal amplitude may be selected for delivery of dorsal column stimulation. In some examples, the dorsal root and/or peripheral nerve location(s) may be associated with a particular type or location of pain to be treated by the dorsal column stimulation. The evoked signals may be evoked by delivery of stimulation to one or more dorsal root locations and/or one or more peripheral nerve locations. To select or identify the one or more dorsal column locations, the one or more locations may be evaluated based on one or more parameters of evoked signals sensed at respective dorsal column locations. In some aspects, the disclosure relates to techniques for selecting or identifying one or more stimulation locations on the dorsal column of a patient, e.g., target stimulation locations on the left and/or right dorsal columns for delivery of stimulation therapy to treat pain experienced by a patient.
