Objective:

Present information regarding the evidential basis of acupuncture.

General Key Points:

  • Evidence exists regarding the applications and effectiveness of acupuncture.
  • While most studies have been performed on humans or experimental animals, a handful of papers on veterinary patients have been published.

Overview of the Issue

In 1997, the National Institutes of Health issued a consensus statement of acupuncture, reflecting the assessment by a nonadvocate, non-Federal panel of experts of the medical knowledge available at the time. According to the Consensus Statement, “[P]romising results have emerged, for example, showing efficacy of acupuncture in adult postoperative and chemotherapy nausea and vomiting and in postoperative dental pain. There are other situations, such as addiction, stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, low back pain, carpal tunnel syndrome, and asthma, in which acupuncture may be useful as an adjunct treatment or an acceptable alternative or be included in a comprehensive management program. Further research is likely to uncover additional areas where acupuncture interventions will be useful.”

Since 1997, hundreds more studies have been published on acupuncture. The outcomes of some of this research is presented below.

Additional Detail

One form of acupuncture, known as “PENS” (percutaneous electrical nerve stimulation) approaches pain treatment from a decidedly neuroanatomic perspective, treating the patient’s pain pattern along dermatomal, myotomal, and sclerotomal trajectories. PENS differs from electroacupuncture by having a certain needle placement, lead pattern, and electrical frequencies generated.1 Research on PENS has focused on headache2,3, diabetic neuropathic pain4, postherpetic neuralgia5, sciatica6, low back pain7,8, and pain secondary to bony metastasis9.

Other research on acupuncture for pain appears in the following table.

  • Low back pain: Acupuncture dry needling are useful for chronic low back pain.10-13
  • Knee osteoarthritis: Acupuncture improves pain and function in patients with knee osteoarthritis.14
  • Chronic visceral hyperalgesia: EA effectively treats visceral pain in rats subjected to colorectal distention, as an irritable bowel syndrome model15
  • Peri-operative analgesia: Acupuncture helped stabilize pulse rate and blood pressure during maxillofacial surgery.16
  • Lateral epicondyle pain: Acupuncture provides short-term relief for lateral epicondyle pain.17
  • Chronic orofacial pain: Acupuncture provides significant short term relief for patients with chronic orofacial pain.18
  • Migraine: Ear acupuncture can abort migraines.19,20

Acupuncture helps many conditions in addition to pain. See below for research regarding reproductive conditions.

  • Erectile Dysfunction: The use of acupuncture as a mono-therapeutic modality in ED, did not influence the profile of the stress and sex hormones, but did improve the quality of erection and restored the sexual activity with an overall effect of 39%.21
  • Labor induction: Acupuncture at points LI 4 and SP 6 supported cervical ripening at term and can shorten the time interval between the EDC and the actual time of delivery.22; Transcutaneous electrical stimulation at acupuncture points caused a significant increase in frequency and strength of uterine contractions in women.23
  • Labor pain management: Acupuncture may provide adjunctive pain relief during labor.24
  • Pain control during oocyte retrieval: EA without pre-medication provides pain relief during oocyte retrieval.25

A 2004 review article on the therapeutic roles of acupuncture in functional gastrointestinal disorders compiled several studies, and came up with the following list:26

  • Dysphagia–TENS helped reduce lower esophageal sphincter (LES) resting pressure, improved esophageal peristalsis and LES relaxation, and increased plasma vasoactive intestinal peptide (VIP)–an inhibitory neurotransmitter responsible for LES relaxation.
  • Non-cardiac chest pain–TENS effectively treated visceral heart pain in severe angina pectoris, as well as chest pain from esophageal origin.
  • Nausea and vomiting–Several randomized-controlled trials have provided evidence that acupuncture treats nausea and vomiting in various conditions, including post-operative, chemotherapy, pregnancy, and motion sickness. Animal models using ferrets and dogs show similar benefits; the effect appears to be mediated through the vagus nerve.
  • Gastric acidity–EA helps reduce acid secretion in both humans and animals.
  • Functional dyspepsia–Acupuncture effectively reduces dyspeptic symptoms, especially epigastric pain.
  • Antroduodenal dysmotility–acupuncture increases antroduodenal motility in cases of hypomotility, and may inhibit it in cases of hypermotility.
  • Gastric emptying–acupuncture accelerates gastric emptying in a canine model.
  • Gastric dysrhythmia–acupuncture reduces arrhythmia and increases normal gastric slow waves.
  • Post-operative ileus–three RCTs suggest that acupuncture increases GI motility in patients after abdominal surgeries, as evidenced by shortened time to first bowel sound, flatus passage, and excretion.
  • Irritable bowel syndrome–acupuncture improves rectal sensation; lowered sensory threshold to rectal distention is a hallmark of IBS.
  • Constipation–acupuncture helps children with constipation.

The table below includes additional studies on gastrointestinal effects.

  • Effects of acupuncture on intestinal motility: The frequency of intestinal motility stimulated by ST 36 increased during acupuncture stimulation and after stimulation. The frequency of intestinal motility stimulated by BL 27 decreased during the acupuncture and after stimulation.27; Acupuncture at ST 36 induced dual effects, either stimulatory or inhibitory, on gastric motility. The stimulatory effects are mediated in part via vagal efferent and opioid pathways.28; Electroacupuncture (EA) at ST 36 promoted gastric myoelectric activity, which was regulated by the vagus.29
  • Treatment of liver damage: Acupuncture at ST 36 and LR 3 did not prevent acute liver injury but may be effective in treating liver injury induced by carbon tetrachloride in rats.30
  • Gastric acid secretion: Acupuncture performed led to significant reduction in gastric acid secretion.31
  • Acupuncture for GI endoscopy: Acupuncture produced effects similar to conventional premedication.32

Acupuncture can influence cardiopulmonary function as shown in the following table.

  • Safety and efficacy in respiratory problems: “Current published evidence reveals no reason to withhold acupuncture as a safe and potentially effective treatment in patients with bronchial asthma and chronic obstructive lung disease.”33
  • Postextubation laryngospasm: Acupuncture with bloodletting at LU 11 may prevent and treat laryngospasm occurring after tracheal extubation in children.34
  • Modification of cardiovascular function in dogs by acupuncture: Acupuncture at Jen Chung (GV 26) in dogs under halothane anesthesia produces sympathomimetic-like effects on the cardiovascular system. This response can be inhibited by pretreatment with propranolol and to a lesser extent with phentolamine. Severe hypotension and cardiac arrest produced by hypoxia in dogs under halothane anesthesia can be reversed by acupuncture ST 9, a sympathomimetic-like effect. Acupuncture at ST 36 results in a parasympathomimetic-like effect on the cardiovascular system which can be inhibited by atropine. A parasympatholytic-like effect resembling that produced by atropine can be obtained in dogs with sinus arrhythmia by acupuncture at LI 5.35
  • Reversal by acupuncture of cardiovascular depression induced with morphine during halothane anaesthesia in dogs: The depressant effect of morphine on cardiac output, heart rate and mean arterial pressure in dogs under halothane anaesthesia appeared to be reversed by acupuncture by electrocautery at Jen Chung (GV 26).36
  • Cardiovascular beneficial effects of electroacupuncture at PC 6 acupoint in anesthetized open-chest dog: Mean arterial pressure, end-diastolic volume, heart rate, stroke volume, cardiac output, and end-systolic pressure gradually decreased by 5 to 10% over 1.5 h without PC 6 EA. PC 6 EA at 40 Hz, however, increased these cardiovascular variables by 10 to 15%, especially end-systolic elastance (Ees) by 40% (p<0.05) over 15 to 60 min. After PC 6 EA was stopped at 1 h, these facilitated cardiovascular variables decreased below the pre-EA level.37
  • Pressor effect of electroacupuncture on hemorrhagic hypotension: PC 6 EA inhibited a hemorrhage-induced increase in plasma catecholamines. This study demonstrated a scientific basis for the therapeutic efficacy of acupuncture in the treatment of hemorrhagic hypotension and shock.38
  • Cardiovascular and endocrine effects of acupuncture in hypertensive patients: Acupuncture decreased blood pressure in hypertensive patients at least in part from a decrease in renin secretion.39
  • Decreased heart rate by acupuncture stimulation in humans via facilitation of cardiac vagal activity and suppression of cardiac sympathetic nerve: Acupuncture at PC 4 decreased heart rate as a result of a reciprocal coordination of an increase in cardiac vagal activity and a decrease in cardiac sympathetic activity.40
  • Reversal of reflex-induced myocardial ischemia by median nerve stimulation: a feline model of electroacupuncture: PC 6 stimulation (over the median nerve) diminished regional myocardial ischemia triggered by a sympathetically mediated increase in cardiac oxygen demand.41
  • Acupuncture in angina pectoris: Both genuine and sham acupuncture have a specific effect on some angina pectoris patients in addition to the effect of pharmacological therapy.42
  • Acupuncture inhibits sympathetic activation during mental stress in advanced heart failure patients: Acute acupuncture attenuates sympathoexcitation during mental stress in advanced HF patients.43

Because acupuncture works by stimulating nerve fibers, it can help restore neurologic function for a number of conditions, as shown in the following table.

  • Stroke in humans: Acupuncture focally increased CBF in stroke patients especially in the hypoperfused zone surrounding the ischemic lesion, and in the ipsilateral or contralateral sensorimotor area.44; Humans suffering from stroke are more likely to remain independent and in their own homes one year following their stroke if they have received acupuncture.45
  • Parkinson’s Disease in humans: Post-acupuncture improvement in the sleep and rest category (p=0.03) but no improvement in the categories of ambulation, mobility, body and movement, social interaction, communication, alertness behavior, emotional behavior, eating, work, home management, or recreation and pastimes. No adverse effects reported.46
  • Spinal cord injuries in humans: The use of concomitant auricular and electrical acupuncture therapies, when implemented early in acute spinal cord injury, can contribute to significant neurologic and functional recoveries.47
  • Wobbler syndrome in dogs: Some improvement noted in dogs with wobbler syndrome. No adverse effects observed with acupuncture. The use of this technique is proposed for large-scale clinical trials.”48
  • Peripheral nerve injury: Acupuncture facilitates recovery of peripheral nerves, including the median nerve49,50 and radial nerve51.
  • Epilepsy: Ear-point stimulation can potentially effectively treat epilepsy.52

Neuromodulation of sacral and other peripheral nerve function helps improve voiding dysfunction, as shown below.

  • Bladder activity: Acupuncture stimulation to the sacral segment affects both the bladder activity and sleep-arousal system.53
  • Neurogenic bladder in spinal cord injuries (SCI): Acupuncture may be beneficial in the management of neurogenic bladder of SCI, and the earlier the patient received electro-acupuncture therapy, the sooner the bladder balanced.54
  • Incontinence:  The study included 15 elderly women who were treated with manual acupuncture 12 times; almost all outcome measurements were significantly improved even at follow-up 3 months after the last treatment.55
  • Detrusor hyperreflexia incontinence: Acupuncture may represent another valuable therapeutic alternative to the treatment of urinary incontinence caused by detrusor hyperreflexia.56
  • Detrusor instability: 77% of patients with idiopathic detrusor instability were symptomatically cured.57
  • Urinary tract infection: Acupuncture may be a worthwhile alternative in the prevention of recurring lower UTI in women.58,59
  • Recurrent cystitis: The long-term outcome of acupuncture at the SP 6 point for women with frequency, urgency and dysuria was positive, but that the effect was temporary and repeated acupuncture was necessary to maintain beneficial effects.60
  • Renal colic: Acupuncture may be a good alternative for the treatment of renal colic.61
  • Nocturnal enuresis in children: Acupuncture can be useful for childhood nocturnal enuresis when combined with other treatment, including other forms of acupuncture.62

Certain skin conditions respond to acupuncture, as shown below.

  • Canine otitis externa: Acupuncture significantly improved recovery time, pain control, and rate of resolution of secretions.63
  • Neurogenic pruritus: Acupuncture appeared to be effective in alleviating the distressing symptom of itching in patients presenting with neurogenic pruritus.64
  • Atopic dermatitis: Acupuncture eased the effects of withdrawal from steroids in patients with long-standing atopic dermatitis.65

Acupuncture affects immunity, and can influence blood composition, as shown below.

  • Connections between the immune system and the autonomic nervous system: Acupuncture tended to normalize the pattern of leukocytes.66
  • Enhancement of splenic interferon-gamma, interleukin-2, and NK cytotoxicity by S36 acupoint acupuncture in rats.: Electro-acupuncture stimulation of ST 36 acupoint enhanced splenic NK cytotoxicity and that IL-2 and IFN-gamma may function, at least in part, in the regulation of NK cell activity in this system.67
  • Effects on Sepsis: Acupuncture enhanced survival, re-established neutrophil migration, and reduced the number of bacteria in the focus of experimental infection in rats.68
  • Antioxidant status of erythrocytes: Acupuncture improved the antioxidant status of erythrocytes.69

Summary

The evidential basis of acupuncture is increasing in magnitude, making an evidence-based acupuncture practice viable.
