13. Stable management of spinal cord related clinical issues (i.e., spasticity management).
14. Women of childbearing potential must not be intending to become pregnant, currently pregnant, or lactating. The following conditions apply:
15. Women of childbearing potential must have a confirmed negative pregnancy test prior to the baseline visit. During the trial, all women of childbearing potential will undergo urine pregnancy tests at their monthly clinic visits as outlined in the schedule of events.

Women of childbearing potential must agree to use adequate contraception\*\~2\~\* during the period of the trial and for at least 28 days after completion of treatment.

The following conditions apply:

1. Moderate and severe forms of renal dysfunctions (eGFR below 60 ml/min)
2. Clinically significant abnormal laboratory tests (ALT; Alkaline Phosphatase; Bilirubin \[total\]; GGT) as judged by the investigator.

9. Severe anemia (Hgb<8 g/dl) or hypovolemia
10. Participant is a member of the investigational team or his /her immediate family.
11. Participant has undergone electrode implantation surgery.
