Electrical Stimulation

High Frequency Impulse Therapy for Neuromyelitis Optica (NMO)

Phase 2
Waitlist Available

Must have
Be older than 18 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 4 weeks from baseline to completion of the experimental phase.

Summary

This trial looks at whether a self-administered electrical nerve stimulator can help relieve neuropathic pain for people with NMOSD.

Who is the study for?
This trial is for adults with Neuromyelitis Optica (NMO) who have stable disease, no recent spinal cord relapses, and are on a consistent medication regimen. Participants must experience neuropathic pain from a spinal lesion, be positive for aquaporin-4 antibody, and not have had certain heart issues or other treatments that could affect the study.
What is being tested?
The trial tests if using an electrical nerve stimulating device at home can help relieve long-term (>3 months) neuropathic pain in NMO patients. It compares real High Frequency Impulse Therapy to a sham (fake) treatment to see if there's a difference in effectiveness.
What are the potential side effects?
Potential side effects may include skin irritation where the device is applied, muscle twitching during use of the device, discomfort or increased pain if settings are too high, and possible allergic reactions to materials like latex used in electrodes.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Experimental armExperimental Treatment1 Intervention
Devices will be programmed by our study coordinator to provide a sham signal or the experimental signal. The location of the TENS electrodes will be determined by the location of the pain with the goal of placing the unit at the top of the dermatological level corresponding to the pain. The study coordinator will assist each subject to place the device appropriately. Treatment will be administered for 1 hour per day for 4 weeks.
Group II: Sham armPlacebo Group1 Intervention
The sham unit looks identical to the experimental unit. There may be a sensation experienced by subjects with the sham device but it does not deliver an electric current as the experimental units. The study coordinator will assist each subject to place the device appropriately. Treatment will be administered for 1 hour per day for 4 weeks.
