About this study

Official title: A Single-arm, Open Label, Single Center, Prospective Study of Ultra-high Frequency (500 KHz) Spinal Cord Stimulation for Treatment of Chronic Back Pain or Lower Limb Pain

This study is a prospective, single-arm, open label, single center to confirm the effectiveness and safety of an ultra-high frequency (500 KHz) spinal cord stimulation in patients with chronic back pain or lower limb pain.

Read the detailed description

This study is a prospective, single-arm, open label, single center to confirm the effectiveness and safety of an ultra-high frequency (500 KHz) spinal cord stimulation in patients with chronic back pain or lower limb pain. The trial length is 14 days. Patients will be given ultrahigh frequency pulse stimulation, up to 3 times in every 24 hours, and VAS will be obtained at least once a day. Compared to previous study conducted last year, patient can now have two lead implant sites for different pain locations. The electrode implantation site will be epidural space instead of Dorsal Root Ganglion (DRG).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GiMer Medical MN 1000 External StimulatorDevice

    Trial stimulator (GiMer Medical Model 1000 External Stimulator) to generate pulsed ultrahigh frequency (>200KHz) electrical stimulation, delivered via lead in epidural space, in treating pain. Similar with current market available Spinal Cord Stimulators but with a higher stimulation frequency (hundred KHz) range.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Visual Analog Score From Baseline to Day 14

    To assess the analgesic effectiveness of ultra-high frequency spinal cord stimulation, as measured by Visual Analogue Scale (VAS, score min 0 no pain to max 10 worst pain) compared to baseline.

    Measured: 14 days

  2. Record Incidence of Adverse Events

    To evaluate safety of ultra-high frequency spinal cord stimulation by identifying the incidence rate of adverse events (AEs) and serious adverse events (SAEs) during the trial

    Measured: 14 days

Secondary outcomes (4)
  1. The Brief Pain Inventory (BPI)

    The change from baseline in functionality using the BPI evaluations

    Measured: 14 days

  2. Incidence of Stimulation-induced Paresthesia

    To determine the presence or absence of stimulation-induced paresthesia.

    Measured: 14 days

  3. Pain Relief Medication Consumption

    Amount of pain medication consumption, including Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) and weak opioids, compared to baseline

    Measured: 14 days

  4. Oswestry Low Back Pain Disability Questionnaire (ODI)

    The change from baseline in functionality using the ODI evaluations

    Measured: 14 days

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Visual Analog Score From Baseline to Day 14 (time frame: 14 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
