Sham Acupuncture

Sham acupuncture is not an inert placebo

Many Randomised Controlled Trials use ‘sham acupuncture’ as a pill-equivalent placebo.  Sham acupuncture can involve needling at non-acupuncture points.  This is not the same as taking an inactive pill; it is not an inert placebo!  Consequently, these trials often show that the difference between sham and ‘real’ acupuncture is not always significant (negative outcome). But in some trials where usual care is investigated against sham and ‘real’ acupuncture, both types of acupuncture perform better than usual care (positive outcome). This means those research trials using sham acupuncture will sometimes report ‘real’ acupuncture is not effective, yet often trials of acupuncture versus ‘usual care’ or some other intervention, will give a positive outcome. 

Traditional Methods

Often Not
Tested

Another problem is that many research trials often do not use Traditional Medicine treatment methods and ‘under treat’, instead they are testing ‘Medical’ or ‘Western’ Acupuncture, which is different to Traditional Chinese Medicine Acupuncture. The equivalent mistake would be using for example, insulin (used for diabetes) to treat a headache, rather than a painkiller and saying the insulin did help the headache (not surprisingly!). 

The dose is important and is often inadequate compared to clinical practice (especially in China where it is used in hospitals, often daily).  So the equivalent would be having a severe headache and taking a pinch of paracetamol and expecting it to dull your headache pain.

Quality of Research

Lack of funds

There is not any money in researching acupuncture unlike medications, so good quality research studies are limited due to underfunding.

With these limitations in mind, I’ve selected some research studies which I’ve referenced on this website and used more generally to inform my work as an acupuncturist.

Benefits

The following effects of acupuncture have been proposed:

  • Modulating endocrine and neuroendocrine
  • Increasing blood flow to the uterus and ovaries
  • Modulating cytokines
  • Modulating endogenous regulatory systems, including sympathetic nervous system – this regulates fertility hormones.
  • Reducing stress, anxiety and depression

Acupuncture improves IVF chances.

  • Increases number of follicles and retrieved eggs, thickness of endometrial lining and implantation success.
  • Acupuncture increases the odds of clinical pregnancy (65% compared with controlled groups).
  • Acupuncture is associated with 13% more births (61%) than IVF only (48%) or acupuncture only on day of embryo transfer (51%).

Benefits

  • Acupuncture decreases levels of male hormones or androgens, leading to less acne and hirsutism.
  • Menstrual frequency is increased.
  • Blood sugar and insulin levels are decreased, so controls hyperglcaemia.
  • Reduces cortisol levels
  • Lowers sympathetic nerve activity “flight or fight”
  • Increases blood flow to the ovaries.
  • Benefits are superior to exercise alone.

Benefits

The studies for acupuncture and acupressure are limited and most tend to be done during labour.

  • Acupuncture may increase satisfaction with pain management and reduce use of drug analgesia.
  • Acupressure may reduce pain intensity.
  • Acupressure probably reduces the need for caesarean section.

Benefits

Research shows acupuncture influences neurochemical modulation and secretion, especially beta-endorphins, which has wide ranging therapeutic impacts in particular mood, sleep and vasomotor symptoms.  It reduces cortisol which then influences abdominal obesity, cognition and osteoporosis.

  • Reduces the frequency and severity of hot flushes.
  • Improves in sleep quality.
  • Warm acupuncture increases bone mineral density of the femur and lumbar spine and electroacupuncture relieves osteoporosis pain. Thought to be due to reducing cortisol levels which increases post menopause. Also increases serum oestrdiol.
  • Has some positive effects on improving cognitive scores.
