Focused TECAR therapy for lower back pain from a herniated lumbar disc

Evaluation of the Effectiveness of Focused Radiofrequency (TECAR) Therapy on Pain, Disability, Function, and Quality of Life in Patients With Lumbar Disc Herniation

Ankara City Hospital Bilkent · NCT07335718

This project will test whether focused radiofrequency (TECAR) therapy combined with a home exercise program helps reduce pain and improve function and quality of life in adults aged 20–60 with lumbar disc herniation.

What this trial studies

Adults aged 20–60 with chronic (over 12 weeks) lumbar disc herniation will be enrolled in a prospective, randomized, double-blind trial and assigned to receive focused radiofrequency (TECAR) therapy plus a standardized home exercise program or a control/sham procedure with the same exercise program. The planned sample size is 54 participants to achieve 95% statistical power. Key outcomes — pain (VAS, NRS), disability (Oswestry Disability Index, Roland-Morris), quality of life (SF-36), lumbar mobility (finger-to-floor distance, Schober) and depressive symptoms (Beck Depression Inventory) — will be measured before treatment, immediately after treatment, and one month after treatment. Treatments will be delivered in the outpatient Physical Therapy and Rehabilitation unit at Ankara Bilkent City Hospital by trained technicians and clinicians.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20–60 with a diagnosed lumbar disc herniation and persistent low back pain for more than 12 weeks who can follow a home exercise program and attend outpatient visits at the study center.

Not a fit: Patients with prior lumbar surgery, neurological deficits, sequestered herniation, spinal stenosis meeting exclusion thresholds, spondylolisthesis, polyneuropathy, cardiac implants, active malignancy, or other excluded conditions are unlikely to benefit from or be eligible for this protocol.

Why it matters

Potential benefit: If successful, this approach could reduce chronic low back pain and improve function and quality of life using a noninvasive physical therapy option.

How similar studies have performed: Some small trials and clinical reports of TECAR and related diathermy-type therapies report pain relief for musculoskeletal conditions, but high-quality randomized evidence specifically for lumbar disc herniation remains limited.
