Effect of Spinal Cord Stimulation (SCS) on Insulin Secretion in Humans

Not Applicable

Withdrawn

• Conditions: Spinal Cord Stimulation; Insulin Secretion

• Registration Number: NCT05794776
• Lead Sponsor: University Hospital Tuebingen

Brief Summary

This trial investigates the effect of BurstDR and tonic spinal cord stimulation (SCS) on glucose metabolism and heart rate variability in patients with neuropathic pain.

Detailed Description

This study investigates the effect of spinal cord stimulation (BurstDR stimulation versus tonic stimulation versus no stimulation) on glucose metabolism, insulin secretion and heart rate variability in patients with neuropathic pain. To assess insulin secretion, hyperglycaemic clamps are performed in 10 patients. Three different stimulation conditions (BurstDR, tonic and no stimulation) are tested in 10 hyperglycaemic clamps each. A total of 30 clamps are carried out.
