2. Clinically significant back disease or clinical sign of spinal root affection or spinal stenosis at the discretion of the physician.
3. Clinically significant systemic disease at the discretion of the physician.
4. Patient with other diseases that are expected to affect the ability to walk or the use of the arms at the discretion of the physician.
5. Patients who cannot cooperate or are unable to complete the project and patients who do not speak Danish or English.
6. Impaired kidney function (eGFR < 80 ml/min.)
7. Epilepsy or medical history of seizures.
8. Risk factors for seizures (reduced seizure threshold) either due to drug treatment (e.g. antipsychotics, antidepressants, anti-malaria drugs, tramadol, theophylline, sedating anti-histaminergic drugs) or other diseases (e.g. previous significant head trauma or diabetes with frequent episodes of significant hypoglycemia) as evaluated by an experienced neurologist.
