Electroacupuncture- Promotes Tissue Healing, Relieves Pain

Electroacupuncture releases reparative mesenchymal stem cells into the bloodstream that help in tissue repair.

Highlights

Acupuncture is an ancient Chinese medical practice of inserting needles into the skin at certain points to relieve pain and other conditions.
Electroacupuncture is a form of acupuncture that uses small electric current to stimulate the brain.
This stimulation facilitates the release of reparative stem cells into the bloodstream to promote tissue repair and relieve pain.

Electroacupuncture triggers a neurological mechanism that can help promote tissue repair and relieve injury-induced pain.

The study was led by researchers from the Indiana University School of Medicine.

Acupuncture Benefits Outcome in Carpal Tunnel Syndrome
Both peripheral and central neurophysiological changes in carpel tunnel syndrome may be halted or even reversed by electro-acupuncture interventions.

‘Electroacupuncture increases pain threshold for injury and produces a type of collagen that promotes tendon repair and anti-inflammatory cells that facilitate faster healing.’

The study describes how electroacupuncture stimulates the brain to facilitate the release of stem cells by stimulating the brain through small electrical current. It also adds new insight relating to the cells’ healing properties.

Electroacupuncture is a form of acupuncture that uses a small electrical current to augment the ancient Chinese medical practice of inserting fine needles into the skin at pre-determined points throughout the body.

For the study, a team of more than 40 scientists at institutions in the United States and South Korea was led by four senior authors including IU School of Medicine’s Maria B. Grant, MD, Marilyn Glick Professor of Ophthalmology.

Lose Weight With Psychological Acupuncture
A researcher at Gold Coast’s Bond University suggests that opting for a psychological acupuncture could help reduce food cravings and lose weight.

"This work is a classic example of the power of team science, where investigators in different institutions with specific expertise worked together to unravel the complexity of how electroacupuncture works to help the body respond to stressors," said Mervin C. Yoder, MD, co-corresponding author.

The researchers performed a series of lab tests involving humans, horses and rodents.

Acupuncture Improved Recovery in Women Who Have Undergone Mastectomy
Acupuncture in the hospital after mastectomy is not only feasible, but also appears to decrease patients' symptoms of pain, nausea, and anxiety.

They followed the effects of electroacupuncture from the point of stimulus of the needle all the way to the brain, resulting in the release of reparative mesenchymal stem cells (MSCs) into the bloodstream.

Within 9-22 minutes, depending on the species, electroacupuncture led to activation of the hypothalamus, the part of the brain that controls the nervous system and involuntary bodily functions such as heart rate and digestion.

Test Your Knowledge on Knee Pain
Knee pain is often a consequence of the erect posture of humans, due to which the knee joints have to take the weight of the body. It causes symptoms of discomfort and disability in people of all age groups. Knee joint replacement has revolutionized the treatment of several knee joint diseases that cause pain.

The stem cells were mobilized within two hours.

"The acupuncture stimulus we’re giving these animals has a rapid effect on neuroanatomical pathways that connect the stimulus point in the arm to responsive neurons in the spinal cord and into a region in the brain called the hypothalamus. In turn, the hypothalamus directs outgoing signals to stem cell niches resulting in their release," said Dr. Fletcher A. White, PhD, who is a neuroscientist at the Richard L. Roudebush VA Medical Center in Indianapolis.

The benefits of electroacupuncture treatments seen were:

increasing thresholds for injury-induced pain
increasing the presence of a type of collagen that promotes tendon repair and anti-inflammatory cells known to promote faster healing time

These findings could lead to development of new strategies for tissue repair and pain management related to injuries.

"We could potentially capture the MSCs from an individual’s blood following electroacupuncture and save the cells for future re-introduction in the patient post-surgery or to treat chronic pain due to an injury," Fletcher added.

The findings are published in the journal Stem Cells.
