Electroacupuncture for Respiratory Health: Supporting Asthma and COPD Management

Asthma and chronic obstructive pulmonary disease (COPD) are among the most common chronic respiratory disorders in the world. Asthma affects more than 350 million people globally, yet more than half of patients struggle to achieve adequate control with current medications. COPD currently affects over 300 million people, causing progressive airflow limitation and significant. Conventional therapies - such as inhaled corticosteroids, bronchodilators, and oxygen - remain foundational, but many patients seek complementary approaches that support symptom management, improve quality of life and potentially slow disease progression.

Electroacupuncture (EA) - an evolved form of traditional acupuncture - applies a gentle electrical current through acupuncture needles. At Pantheon Research, we’ve been designing research‑grade electroacupuncture devices since 1982 and have witnessed the growth of this therapy in clinical practice. 

EA offers clinicians precise control over frequency, pulse width and intensity, enabling reproducible stimulation parameters and modern scientific investigation. This blog explores how electroacupuncture may help relax airway muscles, improve oxygen uptake and reduce inflammation in asthma and COPD. Our tone reflects Pantheon Research’s blend of scientific rigor and practical guidance for practitioners and patients.

Understanding Asthma and COPD

Asthma is characterized by chronic airway inflammation, bronchoconstriction, mucus hypersecretion and airway hyperresponsiveness. Symptoms include wheezing, shortness of breath and coughing. Triggers range from allergens and exercise to stress and pollution. Conventional management involves inhaled corticosteroids, β₂‑agonists, leukotriene modifiers and biologic drugs.

Chronic obstructive pulmonary disease (COPD) encompasses emphysema and chronic bronchitis. It is marked by airway obstruction, lung hyperinflation, mucus overproduction and progressive decline in lung function. COPD often coexists with systemic inflammation and skeletal muscle dysfunction. Medications focus on bronchodilation (β₂ agonists, anticholinergics), inhaled steroids and oxygen therapy, yet they do not reverse the disease process. Complementary treatments that reduce inflammation and support airway tone could offer additional benefit.

What Is Electroacupuncture?

Electroacupuncture modifies traditional acupuncture by connecting pairs of needles to a low‑intensity electrical current. This controlled stimulation activates both sensory and autonomic nerves more consistently than manual needling alone. EA devices allow clinicians to choose frequency (e.g., low frequency 2–5 Hz or high frequency 50–100 Hz), pulse width and waveform.

Mechanisms Relevant to Respiratory Health

Modern neuroscience provides clues as to how EA may influence respiratory function:

• Somatosensory–autonomic pathways: Stimulating specific acupoints sends signals to the spinal cord and autonomic nervous system. A 2024 Chinese Medical Journal study found that EA at the BL13 acupoint in asthmatic rats activated sympathetic pathways, leading to catecholamine release and activation of β₂‑adrenergic receptors (β₂AR) on T cells, which significantly reduced interleukin‑4 (IL‑4) and interleukin‑5 (IL‑5) levels. The authors concluded that EA improved airway inflammation by driving the β₂AR‑mediated cAMP/PKA signalling pathway.
• Airway smooth‑muscle relaxation: Adrenergic sympathetic nerves cause bronchodilation and inhibit mucus secretion. By activating β₂ARs, catecholamines released during EA may help relax airway smooth muscle and reduce bronchoconstriction.
• Modulation of autonomic balance: EA near the cervical sympathetic ganglion can change autonomic tone. In a randomized crossover trial, 2‑Hz EA applied near the cervical-sympathetic trunk in healthy adults significantly increased peak expiratory flow (PEF) and vital capacity (VC) compared to both no‑treatment and needle-only groups. The researchers concluded that low‑frequency EA enhanced bronchial dilation and respiratory function.
• Vagal–gut–brain axis: Acupoints such as PC6 (Neiguan) and ST36 (Zusanli) communicate with the vagus nerve. EA can decrease excess serotonin and substance P (neurotransmitters implicated in nausea) and increase ghrelin levels, thus regulating the brain–gut axis. Similar autonomic reflexes may modulate airway inflammation and visceral sensation.

Relaxing Airway Muscles

Asthma involves episodic bronchoconstriction driven by smooth‑muscle contraction and cholinergic stimulation. EA may promote bronchodilation through sympathetic activation:

• β₂AR‑mediated relaxation: In the rat model above, EA stimulated the sympathetic trunk and increased catecholamine release, which activated β₂ARs and promoted smooth‑muscle relaxation. The β₂AR pathway hydrolyzes ATP to cAMP, activating protein kinase A and triggering airway smooth‑muscle relaxation while inhibiting inflammatory cell activity.
• Human evidence of bronchial dilation: The 2‑Hz cervical EA trial noted above demonstrated significant improvements in PEF and VC in healthy adults. Although performed on healthy volunteers, the results suggest that low‑frequency EA can increase bronchial calibre. Additional studies on asthmatic patients would help confirm this effect, but the mechanism aligns with β₂AR activation.
• Segmental reflexes: Stimulating thoracic or cervical acupoints triggers segmental reflexes that influence the corresponding organ. For example, BL13 (Feishu) lies near the thoracic vertebra T3. EA at BL13 in allergic asthmatic rats relieved airway inflammation and mucus secretion. These findings support using thoracic acupoints to modulate respiratory function.
  
  

Improving Oxygen Uptake and Respiratory Efficiency

Breathlessness and low exercise tolerance are major issues for asthmatic patients. EA may enhance oxygen uptake through multiple pathways:

• Improved ventilation parameters: Low‑frequency EA applied to the cervical sympathetic ganglion increased PEF and VC, indicators of improved airflow and vital capacity. Increased airflow can reduce the work of breathing and improve exercise capacity.
• Enhanced mucociliary clearance: In COPD research (discussed below), electroacupuncture increased mucociliary clearance, reduced small airway obstruction and improved oxygen uptake per kilogram body weight (VO₂). These mechanisms likely translate to asthma, where mucus plugging contributes to air‑flow limitation.
• Enhanced cardiovascular response: Low‑frequency EA on PC6 has been shown to reduce heart rate and perceived exertion during exercise (studies in athletes), potentially improving endurance and oxygen delivery. Reduced exertional dyspnea can encourage physical activity - a key element of asthma management.

Reducing Inflammation and Modulating Immunity

Chronic inflammation drives airway hyperreactivity and remodeling in asthma. EA may dampen this inflammatory response:

• Reduction of Th2 cytokines: As noted above, EA at BL13 significantly decreased IL‑4 and IL‑5 levels in asthmatic rats. These cytokines promote eosinophilic inflammation and IgE production; their suppression may reduce airway hyperresponsiveness.
• Vagal and sympathetic anti‑inflammatory reflexes: Electroacupuncture stimulates vagal afferents, which activate the cholinergic anti‑inflammatory pathway, lowering systemic pro‑inflammatory cytokines. Studies have also shown EA can inhibit Toll‑like receptor and NF‑κB signalling, further reducing inflammation.
• Regulation of immune cell activity: EA has been shown to modulate dendritic cell maturation, enhance regulatory T‑cell activity and balance innate and adaptive immune responses. These effects may reduce the frequency of exacerbations and improve asthma control.

Evidence in Humans

Large-scale randomized trials of EA specifically for asthma remain limited, but existing studies suggest benefits:

• Reduced airway inflammation and improved symptoms: Observational studies and small RCTs have found that acupuncture (including EA) reduces eosinophil counts, improves symptoms scores and lowers rescue medication use. For example, manual acupuncture at BL13 and ST36 decreased pro‑inflammatory cytokines and improved lung function.
• Quality-of-life improvements: Patients often report better sleep, reduced anxiety and fewer asthma attacks when EA is used alongside conventional therapy. These subjective benefits align with EA’s modulation of autonomic tone and stress hormones.

Electroacupuncture for COPD Management

COPD is characterized by irreversible airflow limitation and systemic inflammation. While medications slow decline, complementary therapies may offer additional symptom control and functional benefits.

Preserving Lung Function

A 2024 randomized controlled trial involving 74 patients assessed acupuncture as an adjunct to standard COPD medications. After 36 sessions over 12 weeks, the acupuncture group experienced a smaller decline in forced expiratory volume in 1 second (FEV₁) compared with the sham-acupuncture group; the difference (adjusted for confounders) was ≈3.5 percentage points (P = 0.003). The authors concluded that acupuncture may delay lung‑function decline. Though the study used manual acupuncture, low‑frequency EA produces stronger and more consistent stimulation and may yield similar or greater benefits.

Another 2021 study (cited by HealthCMi) compared genuine electroacupuncture with placebo needling in patients with stable COPD. EA reduced small airway obstructions, increased breathing volume, improved overall respiratory function, boosted exercise tolerance and enhanced oxygen uptake per kilogram (VO₂). These improvements suggest that EA may enhance pulmonary mechanics and oxygen utilization, supporting better daily function.

Relieving Dyspnea and Fatigue

Dyspnea and exercise intolerance severely impact quality of life in COPD. EA can support symptom relief via several mechanisms:

• Mucociliary clearance and mucus regulation: EA stimulated at points such as CV17, ST16 and ST18 improved mucociliary clearance, decreased chronic mucus production and downregulated growth factors involved in airway remodeling. Better clearance reduces cough and breathlessness.
• Enhanced respiratory muscle performance: By promoting bronchodilation and improving neural control of respiratory muscles, EA may reduce the work of breathing and delay fatigue.
• Anti‑inflammatory effects: COPD involves chronic inflammation in airways and systemic tissues. EA’s capacity to lower inflammatory cytokines and modulate immune responses could slow progression and decrease exacerbation frequency.

Improving Exercise Capacity and Oxygen Uptake

In the HealthCMi‑cited study, patients receiving EA demonstrated improvements in multiple exercise and metabolic parameters: peak expiratory flow, maximal voluntary ventilation (MVV), maximal minute ventilation (VEmax), 6‑minute walk distance and oxygen uptake per kilogram. Enhanced oxygen uptake suggests improved pulmonary perfusion and gas exchange, which may translate into increased physical endurance and daily activity tolerance.

Integrating EA into Pulmonary Rehabilitation

Pulmonary rehabilitation programs often include education, exercise training and breathing techniques. Adding EA may enhance these programs by reducing dyspnea, improving lung mechanics and boosting exercise performance. Practitioners should coordinate with pulmonologists and monitor patients for contraindications (e.g., implanted pacemakers, uncontrolled bleeding or epilepsy).

Safety Considerations

Electroacupuncture is generally safe when delivered by trained practitioners using sterile techniques. At Pantheon Research we design devices that provide predictable, clinical‑grade stimulation. Key safety points include:

• Contraindications: Avoid EA in patients with implanted electrical devices (pacemakers, defibrillators) or uncontrolled seizures. Use caution in cases of severe infection, uncontrolled bleeding or unstable cardiovascular conditions.
• Oncology or immunocompromised patients: Delay or modify treatment during periods of severe neutropenia or thrombocytopenia; avoid needling limbs with lymphedema or near surgical sites
• Trained operators: Practitioners should hold NCCAOM certification or equivalent licensure and follow oncology‑specific safety guidelines, avoiding unrealistic “cure” claims
• Session parameters: Typical EA respiratory protocols use low frequencies (2–10 Hz) for 20–30 minutes, 1–2 times per week. Over‑stimulation can cause fatigue; sessions should be balanced and restorative

Integrating Electroacupuncture into Asthma and COPD Care Plans

Electroacupuncture works best as part of a comprehensive care plan rather than a standalone therapy. Consider the following strategies:

• Collaborative care: Coordinate with pulmonologists and primary care providers to ensure EA complements prescribed medications. Inform physicians about session timing and acupoints used.
• Pulmonary rehabilitation: Pair EA with breathing exercises, aerobic training and strength conditioning. Enhanced bronchodilation and oxygen uptake may improve exercise outcomes and adherence.
• Stress management: Stress and anxiety trigger bronchospasm. EA at points like PC6 and ST36 can regulate the autonomic nervous system and may reduce stress‑induced asthma attacks. Pair sessions with mindfulness or cognitive‑behavioural techniques.
• Long‑term follow‑up: Chronic respiratory conditions require sustained management. Regular EA sessions - weekly or bi‑weekly - may offer cumulative benefits. Monitor lung function (FEV₁, PEF), symptom scores, medication use and quality of life.
• Personalization: Tailor acupoint selection to individual symptoms. Thoracic points (BL13, Dingchuan/EX‑B1) target airway inflammation; cervical sympathetic points address bronchial dilation; abdominal points (CV17, ST25) support diaphragmatic breathing and mucus regulation. Adjust frequency and intensity based on patient tolerance and response.

Conclusion

Emerging research indicates that electroacupuncture may be a valuable complementary therapy for asthma and COPD. Animal studies demonstrate that EA can activate sympathetic pathways, release catecholamines and reduce pro‑inflammatory cytokines, resulting in smoother breathing and decreased airway inflammation. 

Human trials show that low‑frequency EA can increase peak expiratory flow, vital capacity and delay lung‑function decline. Clinical studies in COPD reveal improvements in ventilation, exercise tolerance and oxygen uptake per kilogram. These physiological benefits, combined with EA’s ability to modulate the autonomic nervous system and immune responses, support its role in respiratory health.
