Acupuncture Without the Myths: Research, Evidence and Risks
đż Acupuncture Without the Myths
What does research investigate about acupuncture, which mechanisms are being studied, what do studies examine and where are the limits of this method?
What do we know about acupuncture?
Acupuncture is sometimes described in two extremes: either as an almost universal method or as something with no meaningful role at all. Research is more complex. Acupuncture has been studied in relation to a range of health concerns, and findings vary depending on the condition, study design and population examined.
Pain and nausea
Research frequently examines some forms of chronic pain, headaches and selected forms of nausea.
Nervous system
Studies investigate areas such as nerve stimulation, local tissue responses and the processing of sensory signals within the nervous system.
It does not replace healthcare
Acupuncture should not be a reason to delay necessary medical assessment, diagnosis or recommended treatment.
đż What is acupuncture?
In traditional needle acupuncture, a practitioner inserts very thin, sterile and usually single-use needles into selected areas of the body.
The exact procedure, duration and number of sessions may vary depending on the technique used, the practitioner and the individual situation.
Qi and meridians
Traditional Chinese medicine describes acupuncture using concepts such as qi and meridians. These concepts form part of its traditional theoretical framework.
Nerve and tissue stimulation
Modern research investigates possible relationships with the nervous system, local tissue responses and the processing of sensory signals.
đŹ What is studied in acupuncture research?
Acupuncture research does not focus only on the precise location of traditional points. Researchers also examine other factors that may form part of the overall procedure.
Nerve-ending stimulation
Local tissue responses
Sensory signal processing
Biological responses
Muscle and tissue responses
Relaxation during the procedure
Practitioner interaction
Expectations
When evaluating any complementary method, it is important to distinguish between a reported change in symptoms and treatment of the underlying cause of a health problem.
đ§ Why is acupuncture studied in relation to pain?
Pain perception is a complex process involving peripheral nerves, the spinal cord and the brain. Researchers therefore investigate whether and how mechanical stimulation may relate to the processing of these sensory signals.
Studies examine responses to mechanical stimulation of the skin and underlying structures.
Research examines the processing of sensory signals within the nervous system.
Studies also examine how sensory signals are processed and perceived in the brain.
Research also examines other biological responses that may be associated with mechanical stimulation.
đ Which health concerns are studied in acupuncture research?
Acupuncture research covers a range of health concerns. Studies frequently focus on some forms of pain and selected forms of nausea.
- chronic lower back pain,
- chronic neck pain,
- symptoms associated with knee osteoarthritis,
- some types of migraine and headache,
- some postoperative symptoms,
- selected forms of chronic pain,
- some forms of nausea.
Findings cannot automatically be transferred from one health concern to another, nor should the same response be expected in every person.
Information about acupuncture research is not a recommendation for treating a particular health condition. If you have health concerns, discuss appropriate care with a healthcare professional.
đ Why do researchers also study the âwrongâ acupuncture point?
Traditional acupuncture places considerable importance on the precise selection of points. Research studies, however, may also compare traditional acupuncture with superficial stimulation or stimulation outside traditionally defined points.
| Research comparison | What researchers may examine |
|---|---|
| Comparison with usual care or no procedure | Studies may examine differences between groups receiving different approaches. |
| Comparison with control acupuncture | Researchers can examine the possible role of the precise location of traditional points. |
| Superficial or other mechanical stimulation | Research may attempt to distinguish the role of mechanical stimulation from other components of the procedure. |
| Expectations and practitioner interaction | Studies may also examine nonspecific components of the overall experience. |
No. Pain and other subjective symptoms involve complex processing within the nervous system and can be influenced by multiple factors.
This is one reason researchers try to separate the different components of a procedure when interpreting study results.
âïž A change in symptoms is not the same as removing the cause
When evaluating acupuncture, it is important to distinguish between a change in reported symptoms and treatment of the underlying cause of a health problem.
What can studies measure?
Research may measure changes in reported symptoms, everyday functioning or other predefined outcomes.
Diagnosis still matters
A change in symptoms does not by itself establish whether the underlying cause of a health problem has been addressed. Medical assessment may be needed to determine the cause.
It should not be used as a reason to stop or delay medical assessment, prescribed medication, surgery or other treatment recommended by a healthcare professional.
đŹ What do scientific studies examine?
Acupuncture is studied in relation to a range of health concerns. Findings can vary depending on the population studied, the specific health concern, the technique used and the type of comparison.
Research can also be methodologically challenging because the overall procedure includes several factors, such as mechanical stimulation, the setting, practitioner interaction and expectations.
Some studies compare acupuncture with usual care.
Findings may also be compared with a group that does not receive the procedure.
Research may use superficial stimulation or stimulation outside traditionally defined points.
Studies may also compare acupuncture with other non-pharmacological approaches.
Findings relating to one health concern cannot automatically be applied to another. A result from one study also does not mean that every individual will experience the same outcome.
â ïž What does acupuncture not replace?
Acupuncture should not be a reason to delay necessary medical assessment, diagnosis or recommended treatment.
- new or rapidly worsening symptoms,
- acute health problems,
- serious infections,
- cancer,
- serious neurological symptoms,
- conditions requiring urgent medical care.
If you have a health condition, discuss the use of complementary approaches with a healthcare professional, particularly if you are already receiving treatment.
đĄïž What should you consider before acupuncture?
Acupuncture involves inserting needles into the skin, so hygiene, appropriate technique and the use of sterile single-use needles are important.
Reactions may include tenderness at the needle site, minor bleeding, bruising, tiredness or dizziness.
Incorrect or unhygienic technique can carry risks such as infection or injury. Needle insertion in the chest area can also carry a risk of pneumothorax.
- blood-clotting disorders,
- medication that affects blood clotting,
- pregnancy,
- significantly weakened immunity,
- skin infection or injury at the intended needle site,
- implanted electrical devices when considering electroacupuncture.
âš Acupuncture techniques and related methods
These approaches differ in the type of stimulation, invasiveness and the amount of research available.
Traditional needle acupuncture
Uses very thin needles inserted into selected areas of the body.
Electroacupuncture
This technique applies a low-level electrical stimulus through acupuncture needles. Suitability should be considered individually.
Laser acupuncture
Light stimulation is applied to selected areas instead of inserting a needle. It is a different technique from traditional needle acupuncture.
Moxibustion
A traditional method that uses heat near selected areas of the body. Care is required because of the risk of burns.
Acupressure
Acupressure does not use needles. Mechanical pressure is applied to selected areas.
đ©ââïž What should you look for in a practitioner?
Because needle acupuncture is an invasive procedure, hygiene, technique and practitioner training are important.
Training and experience
Hygiene procedures
Sterile single-use needles
Willingness to work alongside healthcare professionals
Be cautious of claims that acupuncture can replace necessary medical diagnosis or treatment for a serious health condition.
đ©ș When should you seek medical care?
Medical assessment is important for new, unexplained or worsening symptoms.
- new or worsening pain,
- unexplained weight loss,
- persistent fever,
- significant weakness,
- changes in sensation or movement,
- unexplained bleeding,
- shortness of breath,
- chest pain.
Seek urgent medical help for sudden severe chest pain, severe difficulty breathing, loss of consciousness or possible signs of a stroke.
â Frequently asked questions about acupuncture
What health concerns are commonly studied in acupuncture research?
Research frequently examines some forms of chronic pain, headaches and selected forms of nausea. Findings vary depending on the specific health concern.
Is acupuncture a placebo?
Research examines different components of the procedure, including stimulation itself, the setting, expectations and practitioner interaction. Different control methods are used to investigate the contribution of these factors.
How long does an acupuncture session take?
The duration can vary depending on the technique, practitioner and individual situation.
Is acupuncture safe?
Because needle acupuncture is an invasive procedure, hygiene, appropriate technique and sterile single-use needles are important. In some situations, suitability should be discussed with a healthcare professional beforehand.
Can acupuncture replace medication or other treatment?
Acupuncture should not be a reason to stop or delay medical assessment or treatment recommended by a healthcare professional.
đż Acupuncture without the extremes
Acupuncture is studied in relation to a range of health concerns. Common research areas include some forms of pain and selected forms of nausea.
Research findings are not the same for every health concern or every individual. When interpreting studies, it is important to consider exactly what was investigated and what acupuncture was compared with.
Acupuncture is best considered as a complementary approach rather than a replacement for necessary medical assessment, diagnosis or treatment.
