Spinal Cord Stimulation System Determining Optimal Sub-Perception Therapy by Using Neural Dose

原文（中国語）

Methods and systems for determining sub-perception stimulation for a patient having a spinal cord stimulator device are disclosed. In one example, an external device includes an algorithm configured to determine a stimulation program for the stimulator device. The algorithm includes a model that comprises pre-determined energy values that cause sub-perception stimulation. The algorithm is configured to determine stimulation parameters for the stimulation program that yield an energy value within the first model. The energy values in the model may be expressed as a function of frequency. The model in particular provides optimal sub-perception stimulation at low frequencies, such as at 1 kHz and below, or even at 400 Hz and below.
