Manual Therapy and Central Sensitization in Chronic Low Back Pain

Introduction Chronic low back pain is one of the most common musculoskeletal conditions worldwide. In many individuals, persistent pain is not only related to tissue injury but also to changes in how the nervous system processes pain signals. This phenomenon is known as central sensitization, where the nervous system becomes more sensitive to pain stimuli and can amplify pain perception even after tissues have healed. Research Overview Manual therapy techniques such as spinal mobilization and manipulation are frequently used in rehabilitation to reduce pain and improve mobility. Researchers have examined whether these interventions can also influence central sensitization mechanisms. A systematic review and meta-analysis analyzing several clinical studies investigated the effect of manual therapy on central sensitization in individuals with chronic low back pain. The findings suggested that manual therapy may lead to modest improvements in peripheral pain sensitivity, meaning that it can reduce local pain responses around affected tissues. However, the available evidence indicates that manual therapy alone may have limited influence on the deeper mechanisms involved in central sensitization within the nervous system. Clinical Interpretation These findings highlight an important concept in modern rehabilitation. While manual therapy can help improve joint mobility and reduce musculoskeletal pain, chronic pain conditions often involve complex neurophysiological processes that require a broader treatment strategy. For this reason, many clinicians recommend combining manual therapy with additional approaches such as therapeutic exercise, neuromuscular rehabilitation, movement retraining, and patient education about pain mechanisms. A multimodal rehabilitation approach may help address both the peripheral and central components of chronic pain.
