Acupuncture has been practiced for centuries as part of traditional medicine and is now also being studied through modern scientific research. It has been explored as a complementary approach for several conditions, particularly certain types of pain, nausea, and other symptoms.
But how might acupuncture actually work?
Modern research suggests that acupuncture may involve several interactions between the nervous system, brain, muscles, and the body’s natural pain-regulation processes. In this blog, let’s explore both the traditional understanding of acupuncture and what current science tells us.
Traditional Understanding: The Concept of Qi
Traditional Chinese Medicine (TCM) explains acupuncture through the concept of Qi, often described as vital energy that flows through pathways known as meridians.
According to this traditional framework, an imbalance or disruption in Qi may contribute to illness or discomfort. Acupuncture involves stimulating specific points with fine needles with the aim of restoring balance.
The concept of Qi is part of the traditional medical framework and does not have a direct equivalent that can be measured scientifically.
Modern researchers therefore focus on physiological changes that may occur when acupuncture points and surrounding tissues are stimulated.
What Does Modern Science Say About Acupuncture?
Research suggests that acupuncture may affect several systems in the body. Its effects are likely not explained by a single mechanism but by a combination of neurological and physiological responses.
1. Effects on the Nervous System
One of the most widely studied areas is the relationship between acupuncture and the nervous system.
When an acupuncture needle stimulates tissues, sensory nerves can send signals to the spinal cord and brain. These signals may influence how the nervous system processes pain.
Pain Modulation
The nervous system constantly receives signals from different parts of the body. Acupuncture stimulation may influence these signals and modify how pain is perceived and processed.
This is one reason acupuncture has been investigated for conditions involving chronic pain.
Release of Natural Pain-Regulating Chemicals
Research suggests that acupuncture may influence the release of naturally occurring substances involved in pain regulation, including endorphins and other neurochemical messengers.
These substances may contribute to changes in pain perception and relaxation.
Autonomic Nervous System
Acupuncture may also influence the autonomic nervous system, which helps regulate functions such as heart rate, digestion, and the body’s stress response.
Some studies suggest that acupuncture may encourage relaxation and reduce aspects of the body’s stress response.
2. Possible Effects on Inflammation
Inflammation plays an important role in many health conditions.
Research has investigated whether acupuncture can influence inflammatory and immune-related processes. Some studies suggest that acupuncture stimulation may affect certain inflammatory mediators and pathways involved in the body’s immune response.
However, the effects can vary depending on the condition, treatment method, and individual.
Acupuncture should therefore not be considered a replacement for medical treatment of an inflammatory disease.
3. Effects on the Brain
Modern technologies such as functional brain imaging have allowed researchers to investigate what happens in the brain during acupuncture stimulation.
Studies have reported changes in areas of the brain involved in:
- Pain processing
- Sensory perception
- Emotional regulation
- Stress responses
- Movement and motor control
These findings suggest that acupuncture may influence the way the brain receives and interprets sensory and pain signals.
4. Muscle and Connective-Tissue Effects
Acupuncture stimulation may also affect tissues around the needle.
Depending on the technique and location, stimulation may influence:
- Muscle tension
- Local blood flow
- Sensory nerve activity
- Connective-tissue responses
These effects may contribute to improved comfort and relaxation in some people experiencing muscle tension or certain types of musculoskeletal pain.
Why Do People Respond Differently to Acupuncture?
Not everyone experiences acupuncture in the same way.
The response may depend on several factors, including:
- The underlying condition
- Duration and severity of symptoms
- Overall health
- Treatment frequency
- Individual nervous-system responses
- Expectations and experiences with treatment
This individual variability is one of the reasons researchers continue to study acupuncture.
What Does the Research Tell Us?
Acupuncture has been studied extensively, particularly for pain-related conditions. Some research suggests that it can provide meaningful benefits for certain conditions, while results are less consistent for others.
It is important to understand that acupuncture is not a guaranteed cure and does not work equally well for everyone.
Research into exactly how acupuncture works is still developing, and more high-quality studies are needed to understand its mechanisms for different conditions.
Understanding the Limitations of Acupuncture Research
Studying acupuncture can be challenging.
Difficulty With Blinding
In clinical research, participants and practitioners are sometimes difficult to fully blind to acupuncture treatment because the procedure involves physical stimulation.
Different Treatment Approaches
Acupuncture treatments can differ in terms of:
- Points selected
- Needle techniques
- Number of sessions
- Treatment frequency
This can make it difficult to compare results across different studies.
Individual Differences
People respond differently to acupuncture, making it challenging to predict exactly who will benefit and by how much.
Acupuncture: Traditional Practice Meets Modern Research
Acupuncture has a long history within traditional medicine, where its effects are explained through concepts such as Qi and meridians.
Modern science approaches acupuncture differently, investigating its potential effects on the nervous system, brain, pain-processing pathways, muscles, connective tissues, and inflammatory responses.
Although researchers are still working to understand all of its mechanisms, evidence suggests that acupuncture may be a useful complementary treatment for certain health conditions.
