Myelopathic Pain and Acupuncture Treatment

Understanding Myelopathic Pain: Causes, Symptoms, and Complications

What Is Myelopathic Pain?

Myelopathic pain refers to pain caused by spinal cord dysfunction or injury, often termed myelopathy. The spinal cord, a bundle of nerves running through the vertebral column, transmits signals between the brain and the rest of the body. When the spinal cord is compressed, injured, or otherwise compromised, it can lead to pain, sensory disturbances, and motor impairments. Myelopathic pain is typically characterized by its central origin, distinguishing it from peripheral neuropathic pain or musculoskeletal pain.

The pain can be acute or chronic, localized or radiating, and may be accompanied by symptoms such as numbness, weakness, or spasticity. The severity and presentation of myelopathic pain depend on the underlying cause and the extent of spinal cord involvement.

Causes of Myelopathic Pain

Myelopathic pain can result from a variety of conditions that affect the spinal cord. Common causes include:

• Cervical Spondylotic Myelopathy (CSM): The most common form of myelopathy in older adults, CSM occurs due to degenerative changes in the cervical spine, such as herniated discs, bone spurs, or thickened ligaments, which compress the spinal cord.
• Spinal Cord Injury (SCI): Traumatic injuries, such as those from car accidents or falls, can damage the spinal cord, leading to acute or chronic pain.
• Spinal Tumors: Benign or malignant tumors in or near the spinal cord can compress or invade neural tissues, causing pain and neurological deficits.
• Inflammatory Conditions: Diseases like multiple sclerosis (MS), transverse myelitis, or neuromyelitis optica can inflame the spinal cord, resulting in pain and sensory changes.
• Vascular Disorders: Conditions like spinal cord infarction or arteriovenous malformations can disrupt blood flow to the spinal cord, causing ischemic pain.
• Infections: Spinal cord infections, such as abscesses or viral myelitis, can lead to inflammation and pain.
• Congenital or Developmental Abnormalities: Conditions like tethered cord syndrome or Chiari malformation can cause myelopathic pain from abnormal spinal cord tension or compression.

Symptoms of Myelopathic Pain

The symptoms of myelopathic pain vary depending on the location and severity of spinal cord involvement. Common symptoms include:

• Pain Characteristics:
  • Burning, aching, or electric-shock-like pain, often radiating to the limbs.
  • Centralized pain in the neck, back, or torso, corresponding to the affected spinal cord segment.
  • Chronic or intermittent pain, which may worsen with movement or certain positions.
• Sensory Symptoms:
  • Numbness or tingling (paresthesia) in the arms, legs, or trunk.
  • Hypersensitivity to touch or temperature (allodynia or hyperalgesia).
  • Loss of sensation in specific areas, indicating nerve damage.
• Motor Symptoms:
  • Muscle weakness or difficulty with coordination, affecting walking or fine motor tasks.
  • Spasticity or muscle stiffness, leading to jerky movements or spasms.
  • Loss of bowel or bladder control in severe cases.
• Other Symptoms:
  • Fatigue, often due to chronic pain and sleep disturbances.
  • Difficulty with balance or gait, increasing the risk of falls.
  • Emotional distress, including anxiety or depression, due to persistent symptoms.

Complications of Myelopathic Pain

Untreated or poorly managed myelopathy can lead to serious complications, including:

• Chronic Pain Syndrome: Persistent myelopathic pain can become a chronic condition, resistant to standard treatments and significantly impacting quality of life.
• Progressive Neurological Decline: Ongoing spinal cord compression or inflammation can lead to worsening motor and sensory deficits, potentially resulting in paralysis.
• Secondary Musculoskeletal Issues: Muscle weakness or spasticity can cause joint contractures or posture abnormalities.
• Psychological Impact: Chronic pain and disability can contribute to depression, anxiety, or social isolation.
• Autonomic Dysfunction: Severe myelopathy may disrupt autonomic functions, leading to issues like blood pressure instability or temperature regulation problems.

Acupuncture for Myelopathic Pain: Mechanisms and Applications

Acupuncture is a traditional Oriental  medicine practice that dates back over 2,500 years. It involves inserting thin, sterile needles into specific points on the body, known as acupoints, to stimulate healing and restore balance. In TOM, acupuncture is believed to regulate the flow of vital energy through meridians, correcting imbalances that cause pain or illness.

From a Western perspective, acupuncture works by:

• Modulating Pain Pathways: Stimulating acupoints activates nerve fibers, triggering the release of endorphins, serotonin, and other pain-relieving neurotransmitters.
• Reducing Inflammation: Acupuncture may decrease pro-inflammatory cytokines and promote anti-inflammatory responses.
• Enhancing Circulation: Needle insertion improves local blood flow, aiding tissue repair and reducing muscle tension.
• Regulating the Autonomic Nervous System: Acupuncture can balance sympathetic and parasympathetic activity, reducing stress and promoting relaxation.

Acupuncture is widely recognized for its efficacy in managing chronic pain conditions, including neuropathic pain, arthritis, and fibromyalgia. The World Health Organization (WHO) endorses acupuncture for pain relief based on clinical evidence. Given that myelopathic pain often involves neuropathic and central pain components, acupuncture’s ability to target these mechanisms makes it a promising therapy.

Acupuncture for myelopathic pain is a tailored, holistic approach that aims to alleviate pain, reduce inflammation, improve neurological function, and enhance overall well-being. Practitioners customize treatments based on the patient’s symptoms, the underlying cause of myelopathy, and their overall health, selecting acupoints that correspond to the affected spinal cord segment and related meridians. The primary goals of acupuncture for myelopathic pain include:

• Pain Relief: Reducing acute and chronic pain, including burning, aching, or electric-shock-like sensations, by modulating central and peripheral pain pathways.
• Inflammation Reduction: Decreasing spinal cord and surrounding tissue inflammation to alleviate pressure and promote healing.
• Neurological Support: Enhancing nerve function and reducing symptoms like numbness, weakness, or spasticity.
• Stress and Emotional Balance: Promoting relaxation and reducing stress, which can exacerbate pain and impair recovery.
• Functional Improvement: Supporting mobility, coordination, and quality of life by addressing motor and sensory deficits.

Mechanisms of Acupuncture in Myelopathic Pain

Acupuncture’s effectiveness for myelopathic pain stems from its multifaceted effects on the nervous system, immune system, and musculoskeletal system. Key mechanisms include:

• Central Pain Modulation: Acupuncture influences the brain and spinal cord’s pain processing centers, such as the periaqueductal gray and dorsal horn, reducing the perception of neuropathic pain. It also upregulates opioid receptors, enhancing the body’s natural pain relief mechanisms.
• Anti-Inflammatory Effects: By modulating cytokines like IL-10 and reducing TNF-α, acupuncture decreases inflammation in the spinal cord and surrounding tissues, which is critical for conditions like cervical spondylotic myelopathy or inflammatory myelitis.
• Neuroprotection and Repair: Acupuncture may promote neurogenesis and reduce oxidative stress in the spinal cord, supporting recovery from injury or degeneration. This is particularly relevant for chronic myelopathy, where ongoing nerve damage contributes to pain.
• Muscle Relaxation and Spasticity Reduction: Stimulation of acupoints can relax hypertonic muscles and reduce spasticity, improving mobility and reducing secondary pain from muscle strain.
• Autonomic Regulation: Acupuncture balances autonomic nervous system activity, reducing sympathetic overactivity (which can amplify pain) and promoting parasympathetic relaxation, which aids recovery.

Acupoint Selection for Myelopathic Pain

Acupuncturists select points based on the location of pain, the affected spinal cord segment (e.g., cervical, thoracic, lumbar), and TOM diagnostic patterns. Common acupoints include:

• Local Points: Points near the affected spinal segment, such as BL11 (Dazhu) or BL12 (Fengmen) for cervical myelopathy, are used to address localized pain and inflammation. These points are needled cautiously to avoid aggravating spinal pathology.
• Distal Points: Points like LI4 (Hegu) and LV3 (Taichong) are used for systemic pain relief, stress reduction, and energy regulation. LI4 is particularly effective for neck and upper body pain, while LV3 supports lower body symptoms.
• Ashi Points: Tender points along the spine or limbs are targeted to provide immediate pain relief and improve local circulation.
• Spinal Huatuojiaji Points: These paraspinal points, located 0.5–1 cun lateral to the spine, are highly effective for myelopathic pain, as they directly stimulate the spinal nerve roots and surrounding tissues.
• Systemic Points: ST36 (Zusanli) and SP6 (Sanyinjiao) strengthen the body’s energy and blood, supporting overall neurological health and immunity.

TOM Diagnostic Patterns

In TOM, myelopathic pain is often associated with patterns like energy and blood stagnation, kidney deficiency, or damp-cold obstruction in the meridians. For example:

• Energy and Blood Stagnation: Characterized by sharp, stabbing pain and stiffness, treated with points like BL17 (Geshu) and SP10 (Xuehai) to invigorate blood flow.
• Kidney Deficiency: Common in degenerative myelopathy, with symptoms like weakness and chronic pain, treated with KI3 (Taixi) and BL23 (Shenshu) to nourish kidney energy.
• Damp-Cold Obstruction: Seen in inflammatory myelopathy, with heavy, aching pain, treated with SP9 (Yinlingquan) and ST40 (Fenglong) to resolve dampness.

Treatment Protocols

Acupuncture protocols for myelopathic pain vary based on the condition’s stage and severity:

• Acute Myelopathy: For acute pain (e.g., post-injury), sessions may occur 2–3 times per week for 2–4 weeks, focusing on pain relief and inflammation reduction. Electroacupuncture may be used to enhance analgesia.
• Chronic Myelopathy: For conditions like cervical spondylotic myelopathy, treatment may extend over months, with weekly or biweekly sessions targeting pain, spasticity, and neurological deficits. Scalp acupuncture may be incorporated to stimulate brain-spinal cord communication.
• Maintenance Phase: Monthly sessions to maintain pain control, support mobility, and prevent symptom flare-ups.

Sessions typically last 30–60 minutes, with needles retained for 20–30 minutes. Adjunctive therapies like moxibustion, cupping, or Tui Na (TOM massage) may enhance outcomes.

Scientific Evidence

Research supports acupuncture’s efficacy for neuropathic and chronic pain, with emerging studies on myelopathic pain:

• A 2019 meta-analysis in Pain Medicine found acupuncture effective for neuropathic pain, reducing pain intensity and improving function.
• A 2021 study in Journal of Pain Research reported that electroacupuncture reduced pain and spasticity in patients with cervical myelopathy.
• A 2020 review in Frontiers in Neuroscience highlighted acupuncture’s neuroprotective effects, suggesting potential benefits for spinal cord repair.

While more research is needed, these findings underscore acupuncture’s role as a safe, complementary therapy.
