Researchers conclude that music electroacupuncture causes improved behavioral changes and benefits to neuronal structures in the hippocampus. In a laboratory experiment on depressive rats, music electroacupuncture outperformed fluoxetine (Prozac) for regulating monoamine neurotransmitter levels. Based on the findings, researchers (Cao et al.) conclude that music electroacupuncture demonstrates effectiveness for the treatment of depression.

In a separate investigation (Tang et al.), two types of acupuncture are found to successfully regulate behavioral changes. Based on the findings, the researchers note that music electroacupuncture and standard pulsed electroacupuncture, may assist in the prevention of Alzheimer Disease. In a controlled experiment, laboratory rats receiving electroacupuncture had decreased latency times, improved swimming distances, and significant reductions of β-amyloid protein levels. β-amyloid (Aβ) proteins are the main constituents of amyloid plaques occurring in Alzheimer disease patients’ brains. The researchers noted that music electroacupuncture and standard electroacupuncture improved “learning and memorizing abilities.” Overall, music electroacupuncture outperformed standard electroacupuncture. 

Music electroacupuncture differs from standard electroacupuncture by switching frequencies and waveforms in rhythmic patterns instead of a consistent pulse. Choices of electroacupuncture settings are based on five musical notations (Gong, Shang, Jue, Zhi, Yu). Each setting corresponds to Traditional Chinese Medicine principles of the Five Elements (wood, fire, earth, metal, water) and their corresponding organ systems (liver/gallbladder, heart/small intestine, spleen/stomach, lung/large intestine, kidney/bladder). The settings are adjusted for different diagnosis of each patient.

The Healthcare Medicine Institute (HealthCMi) has not had a chance to test the music electroacupuncture device yet however, we recently tested the ITO ES-160 electroacupuncture device and confirmed its efficaciousness for the alleviation of pain using the sweep mode. Sweep mode involves a gradual increase and decrease of pulse frequencies over time. The adding of subtle gradations between frequency changes in sweep mode demonstrated significant clinical advantages for the treatment of several pain conditions. While the ES-160 has standard intermittent modes, it shows the sweep mode is an important addition.

The laboratory research finds that music electroacupuncture and conventional pulsed electroacupuncture are effective in treating depression in rats. Researchers (Tang et al.) from Beijing University of Chinese Medicine determined, through a protocolized investigation, that both types of electroacupuncture produced positive outcomes in depressed rat models, but music electroacupuncture produced the highest rate of positive outcomes across various metrics. Given the prevalence of depression in society, this research includes important subjective and objective findings.

In this laboratory study, rats receiving electroacupuncture (either music or conventional) displayed higher horizontal activity, vertical activity, sugar consumption, body mass, and expression of serotonin (5-HT), dopamine (DA), and norepinephrine (NE) in the frontal lobe and hippocampus. Additionally, rats treated with music electroacupuncture reported having a higher 5-HT expression than those treated with conventional electroacupuncture. Overall, music and conventional pulsed electroacupuncture demonstrated antidepressant effects in rats, however, music electroacupuncture demonstrated a greater regulatory effect on monoamine neurotransmitters than conventional pulsed electroacupuncture and fluoxetine.

The experiment involved several controlled variables. A total of 50 depression model rats were divided into 5 equal groups of 10 as follows:

  • Control group: Rats were grouped together. Unlimited supply of water and food was provided. Did not receive any stimulation.
  • Model group: Rats were isolated. Received 21 days of chronic unpredictable mild stress stimulation.
  • Fluoxetine group: Rats were isolated. Fluoxetine was diluted with saline to a density of 2 mg/ml. For each rat, 10 ml of diluted fluoxetine was administered per kg of body mass. Medication was administered once per day, one hour before chronic unpredictable mild stress stimulation.
  • Standard pulsed electroacupuncture group: Rats were isolated. Treatment was administered one hour prior to chronic unpredictable mild stress stimulation.
  • Music electroacupuncture: Rats were isolated. Treatment was administered one hour prior to chronic unpredictable mild stress stimulation.

The acupuncture point prescription included standard filiform needle stimulation of acupoints Yintang (MHN3) and Baihui (GV20). For each acupoint in the standard pulsed electroacupuncture group, a filiform acupuncture needle was connected to an electroacupuncture device and was inserted horizontally. The tip of the needle was pointed posteriorly for Baihui and downwards for Yintang. The electrical frequency was set to 2/100 Hz and the intensity was set to 1 mA. The needles were retained for 20 minutes. One 20 minute acupuncture session was conducted per day for a total of 21 days.

For the music electroacupuncture group, acupoint selection and treatment of acupoints was identical to that of the pulsed electroacupuncture group. However, instead of a conventional electroacupuncture device, the needles were connected to a music electroacupuncture device. Voltage was set to 2 V and intensity to 1 mA, until the needle tip was vibrating slightly but did not cause the rat to squeak. An antidepressant music electroacupuncture setting was chosen. The needles were retained for 20 minutes while an acupuncture session was conducted per day for a total of 21 days.

The Tang et al. laboratory experiment demonstrated significant improvements in behavioral and objective results, including improvements in serotonin (5-HT), dopamine (DA), and norepinephrine (NE) levels determined by radioimmunoassay in depression model rats. Additional testing with human subjects is required, including large sample size meta-analyses, to determine the overall efficaciousness of music electroacupuncture for the treatment of depression. The Healthcare Medicine Institute plans on taking a closer look at this innovative approach to electroacupuncture.
