Abstract
A spinal cord stimulation device having a stimulation unit for generation and delivery of stimulation pulses, a control unit for controlling the stimulation unit with respect to stimulation intensity and an autonomic nervous system (“ANS”) sensing unit that is configured to generate ANS indicating signals that represent an increased sympathetic tone or an increased parasympathetic tone, respectively. The control unit is configured to control the intensity of respective stimulation pulses depending on a respective ANS indicating signal as generated by said ANS sensing unit.
Claims14
A spinal cord stimulation device comprising:
- a stimulation unit for generation and delivery of stimulation pulses;
- a control unit for controlling the stimulation unit with respect to stimulation intensity;
- and
- an autonomic nervous system (“ANS”) sensing unit that is configured to generate ANS indicating signals representing an increased sympathetic tone or an increased parasympathetic tone, respectively, said control unit being configured to control the intensity of respective stimulation pulses depending on a respective ANS indicating signal as generated by said ANS sensing unit.
A method for controlling a spinal cord stimulation device, said method comprising the steps of:
- acquiring values of a parameter that is indicative for a status of an autonomic nervous system;
- evaluating acquired values of said parameter that is indicative for a status of an autonomic nervous system;
- generating a control signal based on the evaluation;
- and
- controlling generation of stimulation pulses depending on said control signal.
