Patient Feedback System Assessment

Patient Feedback and System Behavior

• When the patient's perception is more than desired at rest, the current amplitude is at the target amplitude, and the solution is to decrease the target amplitude.
• When the patient's perception is less than desired at rest, the current amplitude is at the target amplitude, and the solution is to increase the target amplitude.
• If the current amplitude is not returning to the target amplitude, the patient reports a pulsating perception, and the solution is to decrease the recovery threshold or increase the reaction threshold.

System Behavior During Activity

• If the patient feels discomfort from stimulation during an activity and the amplitude is not decreasing, the solution is to decrease the reaction threshold.
• If the patient feels discomfort from stimulation during an activity and the amplitude is not decreasing until some time into the activity, the solution is to decrease the reaction threshold.
• If the perception felt by the patient is less than desired during an activity and the amplitude is decreasing too often, the solution is to increase the reaction threshold.
• If the amplitude is decreasing too much during an activity, the solution is to set the reaction speed to a slower setting.

Pulsating Perception During Activity

• If the patient reports a pulsating perception during an activity and the amplitude is frequently changing, the solution is to set the recovery speed to a slower setting or set the reaction speed to a slower setting.

Transition to Comfortable Level

• If the patient initially feels uncomfortable perception that transitions to a comfortable level over time during an activity and the amplitude is reducing slowly, the solution is to set the reaction speed to a faster setting.

Returning to Rest After Activity

• If the patient reports a fast increase in stimulation perception or pulsating perception when returning to rest after an activity and the amplitude is returning to target amplitude quickly, the solution is to set the recovery speed to a slower setting.
• If the patient feels that it takes a long time to get back to comfortable perception when returning to rest after an activity and the amplitude is very slow to return to target amplitude, the solution is to set the recovery speed to a faster setting.
