Systems, methods, and devices for evaluating lead placement based on patient physiological responses

A method, comprising:

• applying, at least in part via a lead, an electrical stimulation to a patient by increasing a stimulation parameter over time;
• detecting, via an observation by a healthcare professional or via feedback provided by the patient, an anal sphincter response, a bellows response, and a toes response from the patient as a result of the electrical stimulation;
• determining a first value of the stimulation parameter associated with the anal sphincter response, a second value of the stimulation parameter associated with the bellows response, and a third value of the stimulation parameter associated with the toes response;
• and
• evaluating a placement of the lead inside the patient based on:
• a chronological occurrence of the anal sphincter response, the bellows response, and the toes response;
• a comparison of the first value with a predetermined threshold;
• a deviation of the second value from the first value;
• a deviation of the third value from the first value;
• or
• a deviation of the third value from the second value.

A method, comprising:

• delivering, via a lead implanted inside a patient, a electrical stimulation to a sacral nerve or a pudendal nerve of the patient by gradually increasing a value of a stimulation parameter over time;
• observing, by a healthcare professional or via feedback provided by the patient, an anal sphincter response, a bellows response, and a toes response from the patient as a result of the electrical stimulation;
• and
• determining whether the lead has been well-placed inside the patient based on an observed timing of the anal sphincter response, the bellows response, and the toes response.
