Researchers are conducting a double-blinded, randomized controlled pilot feasibility study to evaluate the Discogen device for treating discogenic back and radicular leg pain. The study involves 40 adults with unilateral radicular leg pain related to disc disease or herniation at specific lumbar levels. The goal is to investigate the safety and feasibility of the Discogen device and measure its effect on pain reduction over 60 days. Participants will be randomly assigned to one of two groups. The treatment group will receive three daily unilateral Discogen low pulsed ultrasound treatments within one week, each lasting 25 minutes. The control group will receive three sham treatments over the same schedule without active ultrasound. Both groups may continue to use medications like NSAIDs or muscle relaxants for pain as needed. During the study, participants will be monitored for adverse events and changes in pain levels using the Numerical Pain Scale at 30 and 60 days. Additional assessments include changes in disability measured by the Oswestry Disability Index. Participants will complete study forms and attend follow-up visits, with safety and effectiveness outcomes collected over the 60-day period.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Active LIPUS Treatment | Sham Procedure (Device Off) |
|---|---|---|
| What it is | A device-based therapy using a customized Low Intensity Pulsed Ultrasound (LIPUS) transducer applied to the lumbar spine at the site of mild to moderate disc herniation for three 25-minute sessions over one week. | A sham procedure matching the LIPUS device application in all aspects except that the power generator is off, providing no active ultrasound during the same time schedule. |
| Role in the trial | Assigned intervention arm used to evaluate the effectiveness and safety of active LIPUS for disc-related radicular pain. | Control arm used for blinding, replicating all procedures except ultrasound delivery, to distinguish the therapeutic effect of LIPUS from placebo or non-specific procedural effects. |
| Primary use or purpose | To reduce leg and back pain and improve function in adults with MRI-confirmed lumbar disc herniation using targeted LIPUS energy. | To serve as a non-therapeutic control for assessing the effectiveness of the active LIPUS treatment. |
| How the intervention is given or performed | Participants receive three daily 25-minute sessions of LIPUS with device guidance (fluoroscopy/ultrasound for first session) targeting the affected spinal level. The transducer is placed on skin marked during the initial session. | Participants undergo the same three daily sessions and procedures as the active arm, but the ultrasound device remains off, delivering no ultrasound energy. |
| Evidence status or evidence maturity | Previous studies have examined therapeutic ultrasound for low back pain, but the use of this customized LIPUS device for lumbar disc herniation is under clinical investigation; efficacy and safety outcomes from this specific device use are not yet established. | Sham procedure does not provide therapeutic ultrasound; used for blinding and does not address underlying disc pathology. No benefit for pain is expected from the inactive device itself. |
| Important limitations | The LIPUS device protocol and population (unilateral radicular pain, mild to moderate disc herniation) limit generalizability to broader low back pain populations. Short-term follow-up means longer-term benefits and risks are not addressed. | Sham procedures may not fully control for all placebo or behavioral effects. Findings cannot be generalized to untreated or alternative treatment control groups. |
