Abstract

The present invention relates to systems and methods for planning and/or providing neurostimulation for a patient. An example system includes a pathological spinal cord map storage module for storing at least one pathological spinal cord map describing activation of a spinal cord of a patient, a healthy spinal cord map storage module for storing at least one reference map describing physiological activation of the spinal cord of at least one healthy subject, an analysis module for generating a deviation map, the deviation map describing an activation difference between the pathological spinal cord map and the reference map, and a compensation module for calculating, based on the deviation map, a neurostimulation protocol for compensating the activation difference.

Claims (23)

1. A system for planning and/or providing neurostimulation for a patient, comprising:

a pathological spinal cord map storage module for storing at least one pathological spinal cord map describing activation of a spinal cord of the patient,

a healthy spinal cord map storage module for storing at least one reference map describing physiological activation of a healthy spinal cord of at least one healthy subject,

an analysis module configured and arranged such that the pathological spinal cord map and the at least one reference map can be compared and/or analyzed automatically such that a deviation map is created, the deviation map describing an activation difference between the pathological spinal cord map and the at least one reference map, and

a compensation module which is configured and arranged to calculate on a basis of the deviation map a neurostimulation protocol for compensating the activation difference between the pathological spinal cord map and the reference map.

2. The system according to claim 1 , wherein the pathological spinal cord map comprises information about an a-motoneuron activation of the spinal cord.

3. The system according to claim 2 , wherein the information about the a-motoneuron activation of the spinal cord is calculated based on an activation function as weighted sum of electromyography (EMG) data of segments of the spinal cord, using myotomal maps as weights.

4. The system according to claim 1 , wherein the compensation module is configured and arranged such that the neurostimulation protocol is calculated such that the neurostimulation protocol superimposed on the pathological spinal cord map replicates the reference map.

5. The system according to claim 1 , wherein the pathological spinal cord map and the reference map comprise information about a sequence of movements.

6. The system according to claim 5 , wherein the compensation module is configured and arranged such that based on the sequence of movements, the pathological spinal cord map and/or the reference map is segmented for calculation of the neurostimulation protocol for compensation.

7. The system according to claim 6 , wherein the compensation module is further configured and arranged such that from the segmented pathological spinal cord map and the segmented the reference map the segments with the highest deviation are identified to create a distance matrix for the neurostimulation protocol for compensation.

8. The system according to claim 1 , further comprising a stimulation related basic data storage module for storing stimulation related basic data defining parameters of a neurostimulation system for treating a patient, the stimulation related basic data storage module comprising at least one set of stimulation related basic data.

9. The system according to claim 1 , further comprising a stimulation related response data storage module for storing stimulation related response data of neurostimulation provided to the patient, the stimulation related response data storage module comprising at least one set of stimulation related response data including activation of the spinal cord as response to the stimulation.

10. The system according to claim 9 , further comprising a transfer data storage module for storing the transfer data, wherein the transfer data comprise artificial response data and/or link data and/or translation data, which link and/or translate at least partially the stimulation related basic data and the stimulation related response data with each other, the transfer data storage module comprising at least one set of transfer data and a mapping module configured and arranged such that based on the stimulation related basic data and stimulation related response data and the transfer data a digital characteristic map is generated and/or stored, which describes an interrelation between the stimulation related basic data and the stimulation related response data and the transfer data.

11. The system according to claim 10 , further comprising a stimulation related response data input module and wherein the system is configured and arranged such that an inverse control is provided by inputting the stimulation related response data via the stimulation related response data input module and the system further comprising a selection module, which is configured and arranged such that based on the digital characteristic map and the deviation map, suitable stimulation related basic data are selected.

12. The system according to claim 10 , further comprising a neuromodulation settings generation module, which is configured and arranged to translate the digital characteristic map and the deviation map into neuromodulation parameter settings for a neuromodulation treatment of the patient.

13. A method for planning and/or providing neurostimulation for a patient, comprising at least the following steps:

obtaining at least one pathological spinal cord map describing an activation of a spinal cord of the patient,

obtaining at least one reference map describing physiological activation of a healthy spinal cord of at least one healthy subject,

comparing and/or analyzing the pathological spinal cord map and the reference map to create a deviation map, wherein the deviation map describing an activation difference between the pathological spinal cord map and the reference map, and

calculating on the basis of the deviation map a neurostimulation protocol for compensating the activation difference between the pathological spinal cord map and the reference map.

14. The method of claim 13 , wherein the method is completely done in-vitro without connection to the patient.

15. The method of claim 14 , wherein the method is performed offline based on separately obtained patient data.
