Lumbar traction is a gentle, non-invasive technique that stretches and decompresses the lower back to relieve pressure on the lumbar spine. Using a controlled pulling force — applied manually by a therapist or through a traction device — it creates space between the vertebrae, easing pressure on discs, nerves, and joints. It is commonly used for low back pain, sciatica, herniated discs, and muscle spasm, and is often combined with physiotherapy and postural correction programmes.
