Chronic low back pain affects roughly one in five adults and is a leading cause of disability worldwide. Most cases have no single identifiable cause — no disc herniation or fracture — which makes treatment challenging. Current options include physical therapy, medications like NSAIDs or duloxetine, steroid injections, and in some cases surgery.
What's actually going on in research
Trials are testing nerve ablation techniques, regenerative approaches like stem cells and platelet-rich plasma for disc repair, neuromodulation devices that interrupt pain signals, and new classes of pain medications including NGF inhibitors. Researchers are also studying the role of inflammation, central sensitization, and psychological factors in sustaining pain.
Regenerative therapies
Studies are testing stem cells and growth factors injected into damaged discs to promote healing. Early data suggest some people experience pain relief, but durability and patient selection remain open questions.
Nerve ablation
Radiofrequency and cooled radiofrequency ablation burn nerves transmitting pain from facet joints or the sacroiliac joint. Trials are refining which patients benefit most and how long relief lasts.
Neuromodulation
Spinal cord stimulators and dorsal root ganglion stimulators deliver electrical pulses to disrupt pain signals. Newer devices allow more targeted programming and are being tested in people who haven't had surgery.
What to know before you search
Eligibility typically depends on pain duration, prior treatments tried, imaging findings, and whether pain is primarily in the back or radiates into the legs.
What types of trials are currently open
- Regenerative trials — Testing stem cells, platelet-rich plasma, or growth factors injected into discs or joints to promote healing and reduce pain.
- Device trials — Studies of spinal cord stimulators, dorsal root ganglion stimulators, and other implanted or wearable devices that interrupt pain signals.
- Ablation trials — Testing radiofrequency or other techniques to disable nerves transmitting pain from facet joints or the sacroiliac joint.
- Medication trials — Testing new pain medications, including NGF inhibitors and drugs targeting inflammation or nerve pain pathways.
- Behavioral trials — Studies of cognitive-behavioral therapy, mindfulness, and other approaches to managing pain and improving function.
Recently added Chronic Low Back Pain trials
Ultrasound-Guided Thoracolumbar Fascia Injection for Chronic Low Back Pain in Patients With Type 2 Diabetes
This prospective, randomized, controlled clinical trial aims to evaluate the efficacy of ultrasound-guided thoracolumbar fascia (TLF) injection as an adjunct to standard conservative treatment in patients with type 2 diabetes mellitus and chronic nonspecific low back pain. A total of 60 patients aged 18-65 years, diagnosed with type 2 diabetes mellitus for at least one year and experiencing chronic nonspecific low back pain for at least three months, will be enrolled. Eligible participants will be randomly assigned to two groups. The intervention group will receive ultrasound-guided thoracolumbar fascia injection in addition to standard conservative treatment, while the control group will receive standard conservative treatment alone, consisting of patient education and a structured exercise program. Clinical assessments will be performed at baseline and at 1 and 3 months after treatment. Treatment outcomes will include pain intensity measured using the Numeric Rating Scale (NRS), functional disability assessed using the Oswestry Disability Index (ODI), pressure pain threshold (PPT) measured by algometry, and analgesic consumption. Thoracolumbar fascia thickness will be measured using ultrasonography at baseline to investigate its potential association with treatment response. Diabetes-related characteristics, including HbA1c levels, diabetes duration, and peripheral neuropathy status, will also be recorded. The primary objective is to determine whether adding ultrasound-guided thoracolumbar fascia injection to standard conservative treatment provides greater improvement in pain intensity and functional disability compared with standard conservative treatment alone. The study will also explore whether baseline thoracolumbar fascia thickness and diabetes-related characteristics are associated with clinical outcomes.
A Novel Treatment for Chronic Low Back Pain Using Multi Angular Isometric Lumbar Exercise: Randomized Clinical Trial.
The study aims to evaluate the effectiveness of Multi Angular Isometric Lumbar Exercise (MAILE) in comparison to traditional lumbar stabilization and core stability treatments for managing nonspecific chronic low back pain (NCLBP). MAILE is designed to specifically target the Lumbo-Pelvic Hip complex with the goal of improving pain levels, stability, strength, and overall function. Objectives of the study are to assess several key outcomes: Pain Intensity: Measuring the level of pain experienced by patients. Functional Disability: Evaluating the impact of NCLBP on daily activities and overall function. Functional Stability: Assessing the stability of the Lumbo-Pelvic Hip complex during movement. Muscle Strength: Determining the strength of muscles within the targeted region. By examining these outcomes, the research seeks to determine whether MAILE offers superior benefits and greater cost-efficiency compared to conventional treatments for patients with NCLBP and motor control dysfunction. If successful, MAILE could provide a more effective and economical approach to managing this common and debilitating condition. This Randomized Clinical Trial (RCT) will be conducted across multiple outpatient clinics within the Hamad Medical Corporation (HMC). The study will involve 98 patients diagnosed with non-specific chronic low back pain (NCLBP), who will be randomly assigned to one of two groups: the Multi Angular Isometric Lumbar Exercises (MAILE) group or the Core Stability group. Both groups will follow tailored exercise programs over a three-week period. The MAILE group will focus on exercises designed to enhance lumbar stability and core strength through multi-angular isometric lumbar exercises performed at various angles. These exercises aim to target the deep stabilizing muscles of the lumbar spine, promoting overall spinal stability and reducing pain. The Core Stability group will engage in exercises that emphasize the activation and strengthening of the core muscles, which play a crucial role in maintaining spinal stability and function. The outcomes of this trial will help determine the effectiveness of MAILE compared to traditional core stability exercises in managing NCLBP, potentially guiding future therapeutic strategies.
