What Is Cervical Spondylosis?
Cervical spondylosis is the term that describes the degenerative changes that occur in the cervical vertebrae with aging: loss of intervertebral disc height, formation of osteophytes (bone spurs), thickening of the ligaments, and degeneration of the facet joints. It is a virtually universal condition — 90% of people over 65 years old have radiological evidence of cervical spondylosis.
Most cases are asymptomatic or cause only morning cervical stiffness. However, in some individuals, osteophytes and ligament thickening compress the cervical nerve roots (cervical radiculopathy) or even the spinal cord (cervical myelopathy). The typical pain is cervical, and may radiate to the shoulders and arm.
Medical acupuncture does not reverse the structural changes (osteophytes), but acts very effectively on the mechanisms that generate pain: paravertebral muscle spasm, sensitization of the facet joints, and central activation of pain inhibitory systems.
Universal Prevalence
Nine out of ten people over 65 years old show spondylosis changes on X-ray — but only a minority have significant pain.
Spasm Perpetuates the Pain
Spasmodic cervical paravertebral musculature is often the main source of pain, not the osteophytes themselves.
Consistent Evidence
Acupuncture for chronic neck pain shows consistent evidence in meta-analyses, with quality level varying between B and A according to the outcome and study analyzed.
Why Are Conventional Treatments Not Always Sufficient?
NSAIDs are effective for acute flares, but chronic use — unavoidable in patients with persistent neck pain — carries significant gastrointestinal, renal, and cardiovascular risks. In older adults, who represent the majority of patients with cervical spondylosis, these risks are especially relevant.
Physical therapy with cervical strengthening exercises and joint mobilization is effective, but requires good adherence and does not control pain during acute flares. Cervical collars have only limited use and may atrophy the musculature with prolonged use. No conventional conservative treatment has a level of evidence equivalent to that of acupuncture for chronic neck pain.
TREATMENTS FOR CHRONIC NECK PAIN DUE TO SPONDYLOSIS
| TREATMENT | LEVEL OF EVIDENCE | SUITABILITY FOR CHRONIC USE |
|---|---|---|
| Oral NSAIDs | A (acute pain) | Limited (chronic risk in older adults) |
| Physical therapy | B | Good, but requires prolonged adherence |
| Cervical manipulation | B | Moderate (contraindicated in instability) |
| Acupuncture | B–A (variable) | Favorable safety profile in chronic use |
| Acupuncture + PT | B–A | Frequently recommended combined conservative option |
How Does Medical Acupuncture Work in Cervical Spondylosis?
Acupuncture acts on cervical spondylosis through three main mechanisms. The first is inhibition of facet joint pain: inflamed cervical facet joints are richly innervated by medial branches of the dorsal nerves (C3–C8). Acupuncture in the corresponding segments inhibits the nociceptive signal from these joints in the dorsal horn of the spinal cord.
The second mechanism is the relaxation of the cervical paravertebral musculature — especially the semispinalis capitis, splenius, and levator scapulae. These muscles, chronically hypertonic in compensation for cervical instability, develop trigger points that intensify pain far beyond what would be expected from the structural change. Dry needling of these muscles produces immediate relief.
Mechanism of Action in Cervical Spondylosis
Inhibition of facet joint pain (C3–C8)
Segmental acupuncture reduces the nociceptive signal from degenerated cervical facet joints in the dorsal horn.
Needling of the paravertebral musculature
Deactivation of trigger points in the semispinalis, splenius, and levator muscles — the main source of pain in most cases.
Reduction of protective spasm
With facet joint pain and muscle spasm controlled, the pain-spasm-pain cycle that perpetuates the condition is interrupted.
Release of endorphins and serotonin
Long-lasting central analgesia mediated by endogenous opioids and monoaminergic neurotransmitters.
Improvement in cervical range of motion
With relaxed musculature and reduced pain, cervical mobilization exercises become possible and more effective.
What Do Scientific Studies Say?
Chronic neck pain is one of the indications with the largest body of evidence for acupuncture. Meta-analyses published in the highest-impact journals in pain and rheumatology confirm superiority over sham and over usual treatment, with effect sustained at follow-ups of 6 to 12 months.
How Does the Modern Approach Differ?
The medical acupuncturist performs a complete neurological evaluation to distinguish simple spondylosis (without neural compression) from cervical radiculopathy (with root compression) or cervical myelopathy (with spinal cord compression). Each condition has a specific protocol, and cervical myelopathy is a relative contraindication to manipulation — but not to acupuncture.
Low-frequency electroacupuncture in the posterior cervical region is highly effective for chronic facet joint pain. The physician may combine low-power laser therapy over the most compromised cervical discs for additional anti-inflammatory effect. Guidance on deep cervical isometric exercises (deep cervical flexors) is fundamental for long-term stabilization.
When to See a Physician?
Persistent neck pain for more than 4 to 6 weeks, marked morning stiffness, pain that radiates to the shoulders or arms, or limitation in the range of motion of the neck warrants medical evaluation. The physician will request radiography and, if necessary, MRI for adequate staging.
Frequently Asked Questions
No. Acupuncture does not dissolve osteophytes. What it does is reduce the mechanisms that generate pain: paravertebral muscle spasm, sensitization of the facet joints, and central pain processing. Many patients with severe spondylosis on X-ray become virtually pain-free with acupuncture because the pain came mainly from muscle spasm, not from the osteophytes.
The initial protocol is 8 to 12 sessions, with a frequency of 1 to 2 sessions per week. After the initial protocol, monthly or bimonthly maintenance sessions are recommended for patients with chronic spondylosis, since the structural change persists and may cause periodic flares.
Yes, acupuncture is safe and effective for cervical disc herniation with radiculopathy. The protocol is adapted to the affected level (C5–C6 and C6–C7 are the most common), with specific segmental needling. In herniations with significant compression, acupuncture can reduce pain while the physician evaluates the need for interventional procedures or surgery.
Yes, this is one of the great advantages of acupuncture in this population. In older adults with cervical spondylosis who cannot use chronic NSAIDs due to comorbidities (renal insufficiency, heart disease, gastritis), acupuncture is a safe first-line alternative. The physician adapts the protocol to the frailty and comorbidities of the older patient.
Yes, acupuncture is compatible with virtually all medications used in cervical spondylosis (NSAIDs, acetaminophen, muscle relaxants, gabapentin). The combination frequently allows for progressive reduction of medication dose, always under medical guidance.
