BreEStim in Managing Neuropathic Pain After Spinal Cord Injury (SCI)

Официальное название

A Randomized, Double-blind, Sham-controlled, Parallel-group Trial Designed to Evaluate the Efficacy of BreEStim in Managing Neuropathic Pain After Spinal Cord Injury (SCI)

Обзор

The purpose of this study is to compare the effectiveness of innovative intervention of breathing controlled electrical stimulation (BreEStim) and sham BreEStim and Transcutaneous Electrical Nerve Stimulation (TENS) in management of neuropathic pain in patients after spinal cord injury (SCI).

Вмешательства

• Устройство Active BreEStim Treatment
  During the Active BreEStim Treatment session, participants will remain relaxed while breathing is monitored using a nasal cannula. Surface electrodes will be placed over the median nerve at the wrist or another selected peripheral nerve. Electrical stimulation will be synchronized with voluntary breathing and delivered at an individually tolerated intensity for approximately 30 minutes.
• Устройство Sham BreEStim Treatment
  During the Sham BreEStim Treatment session, participants will remain relaxed while breathing is monitored using a nasal cannula. Surface electrodes will be placed over the median nerve at the wrist or another selected peripheral nerve. Electrical stimulation will be synchronized with voluntary breathing and delivered at the sensory threshold level for approximately 30 minutes.
• Устройство The TENS Treatment
  During the TENS Treatment session, participants will remain relaxed while transcutaneous electrical stimulation is applied through surface electrodes placed over the painful area. Stimulation will be delivered at an individually tolerated intensity for approximately 30 minutes.

Первичные конечные точки

• Change in Pain Level as Measured by the Visual Analog Scale (VAS). [Срок оценки: Baseline, 10-15 minutes after intervention]

Вторичные конечные точки (2)

• the difference in the percentage of responders between active BreEStim and Sham BreEStim groups [Срок оценки: Baseline, 10-15 minutes after intervention]
• the difference in the percentage of responders between between active BreEStim and transcutaneous electrical nerve stimulation (TENS) groups. [Срок оценки: Baseline, 10-15 minutes after intervention]
