Chronic back pain often persists long after an injury has healed or a structural problem has been addressed, and neurologist Dr. Eric Anderson, Chief Medical Officer of Lin Health, says the explanation may lie in the brain and nervous system. In a new announcement, Anderson highlighted the process known as central sensitization, in which the nervous system becomes increasingly sensitive to external signals and essentially turns up the volume on pain. "Chronic back pain can be incredibly disruptive," Anderson said, noting that the condition can continue even when conventional treatments have resolved the original issue.
The implications are significant for the millions of people who undergo surgery, injections, or medication without lasting relief. Research cited by Lin Health found that in one study of people with chronic back and neck pain, central sensitization was the primary driver of pain in 88.3% of cases. That finding suggests the source of persistent pain may not be limited to the back itself, opening the door to treatments that address how the brain processes and generates pain signals rather than focusing solely on the area that hurts.
Behavioral therapies are designed to reduce the nervous system's heightened sensitivity and change how the brain responds to signals. Lin Health's virtual pain recovery program incorporates these strategies through one-on-one coaching, ongoing messaging, and self-guided digital modules and exercises. The company, which has earned a 4.9 rating on Trustpilot, presented new outcomes research at the 2026 Annual Meeting of the American Society of Pain & Neuroscience. The study examined 1,620 people enrolled in the program, including 613 whose primary complaint was back pain. Among participants with back pain who completed follow-up assessments, average pain intensity declined within the first month and had fallen by more than one point on a 10-point scale by the third month. Participants with other types of musculoskeletal pain also reported improvements.
The full findings are available in the ASPN Abstract and the accompanying study poster, which Lin Health says add to the evidence that treatments targeting the nervous system can help patients find relief. The approach aligns with clinical guidelines but is rarely implemented effectively in traditional systems due to access limitations, clinician shortages, and fragmented care pathways. Lin Health aims to bridge that gap by delivering scalable, affordable care that is broadly covered by insurance and designed to produce measurable outcomes. For patients whose back pain persists despite conventional treatment, understanding the brain's contribution to the chronic pain experience could open the door to new ways of finding relief.
