Mechanical Traction Applications in Low Back Pain Management

Mechanical traction encompasses a variety of techniques that apply a controlled axial pull to the lumbar spine with the aim of elongating intervertebral spaces, reducing disc pressure and alleviating nerve‐root compression. These methods range from clinician‐delivered manual traction to motorised and computerized spinal decompression devices, as well as emerging wearable exoskeletons. Biomechanically, traction induces distraction of vertebral bodies, encourages rehydration of degenerated discs and may relieve tension on neural elements. Clinically, it is utilised for subgroups of patients with disc herniation, radicular pain or chronic non‐specific low back pain, often in combination with exercise, education and manual therapies. Outcomes in contemporary practice have varied widely, reflecting differences in traction force, rhythm, duration and patient selection. Evidence for short‐term pain relief and functional improvement is moderate, whereas long‐term benefits remain less certain. Advances in delivery systems now offer precise force control and patient feedback, enhancing reproducibility and safety. Despite ongoing debate over optimal dosing parameters, mechanical traction retains global relevance as a non‐invasive adjunct in multimodal management, with particular promise in tailored regimens for identifiable patient subgroups.

Technical terms

Mechanical traction: Application of a controlled pulling force to the spine to stretch soft tissues and reduce disc pressure.

Discogenic pain: Pain originating from a damaged intervertebral disc structure.

Radiculopathy: Symptom complex caused by compression or irritation of a spinal nerve root, manifesting as pain radiating along the nerve pathway.

Spinal decompression: Reduction of intradiscal pressure and restoration of intervertebral height through mechanical means.

Exoskeleton: Wearable device designed to support or augment spinal movement and apply traction forces to the lower back.
