Facial paralysis, also known as peripheral facial paralysis (PFP), is a condition characterised by the acute onset of unilateral weakness of the facial muscles. It is the most common facial nerve disorder, affecting 11.5 to 53.3 per 100,000 persons annually. Patients may experience numbness and paralysis on one side of the face, and symptoms such as drooping of the mouth, drooling, and the inability to frown. The acute onset of this disease can lead to long-term poor outcomes and difficult-to-eliminate sequelae if left untreated. As such, it is important to explore treatment options for PFP. One such option is electro-acupuncture, which combines ancient acupuncture therapy with modern science. This article will discuss the efficacy of electro-acupuncture in treating facial paralysis and explore whether it is a viable treatment option.

Electro-acupuncture for peripheral facial paralysis
Peripheral facial paralysis (PFP) is a condition characterised by the acute onset of unilateral weakness of the facial muscles. It results in functional disorder and social dysfunction, with symptoms such as numbness and paralysis of the face, drooping of the corners of the mouth, and drooling. It is the most common facial nerve disorder, affecting 11.5 to 53.3 per 100,000 persons annually across multiple populations.
Electro-acupuncture (EA) is a treatment that combines manual acupuncture (MA) with electric stimulation. In China, many studies have claimed that EA has an exact curative effect for PFP. EA can regulate the relationship between endothelin secreted by vascular endothelial cells and microcirculation, thereby regulating vasoconstriction or hemodynamics, and ultimately treating PFP. It can also speed up the facial nerve's conduction speed, promote the expression of nerve growth factor protein, and play a role in nerve regeneration and repair after injury.
Randomised controlled trials have been conducted to compare EA with other treatments for PFP. One such trial randomly divided 132 patients with Bell's palsy into electro-acupuncture, manual acupuncture, non-acupuncture, and medicine control groups. The patients in each group were given oral administrations of prednisone, mecobalamin, and fursutiamine until complete recovery. The recovery rate of facial function and the time it takes to restore facial function were key parts of the study.
EA has been widely used in the treatment of PFP. However, the results of clinical studies on its efficacy and safety have been inconsistent. It is difficult to list intuitive evidence of its effectiveness besides evaluation using neurological function scales and a few electrophysiologic data. More intuitive and reliable detection techniques, such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves, are needed to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after applying EA.

Manual acupuncture vs. electro-acupuncture
Manual acupuncture and electro-acupuncture are two commonly used acupuncture interventions. Electro-acupuncture is a modern variation of acupuncture that uses electricity to enhance the benefits of this traditional therapeutic treatment. It is a modified form that uses two needles that can be as far apart as the head and the feet. A small electrode is attached to the needles, and a small amount of electricity runs through the electrode, giving off a slight vibration or soft hum during treatment.
Electro-acupuncture is believed to help increase blood flow, which may help relieve pain. It also warms the muscles and may help with poor circulation and potential blockages. It can also be used to treat chronic stress, as studies have shown that this type of therapy can help reduce long-term chronic stress through stimulation.
Electro-acupuncture is also more accurate than manual acupuncture. It allows for more accurate and uniformly regulated stimulation than can be achieved with manual stimulation alone. It can also cover larger areas of the body than traditional acupuncture.
A series of studies conducted in rats compared the analgesic effect induced by manual acupuncture, electro-acupuncture, and TENS. The analgesic effect of electro-acupuncture was found to be greater than that of manual acupuncture, while electro-acupuncture and TENS produced similar analgesic effects.
However, electro-acupuncture is a fairly new treatment, so there isn't much evidence to support its effectiveness for different uses. It also has some risks associated with it due to the electricity component. Certain individuals, such as those with a history of cardiovascular disease, seizures, or mood disorders, are not recommended to try this therapy.

Effectiveness of electro-acupuncture for acute facial paralysis
Peripheral facial paralysis (PFP), also known as facial paralysis, is a condition characterised by the acute onset of unilateral weakness of the facial muscles. It is the most common facial nerve disorder, affecting 11.5 to 53.3 per 100,000 persons annually across multiple populations. Patients may experience numbness and paralysis on one side of the face, and symptoms such as drooping of the mouth, drooling, and the inability to frown or knit their brows. The acute onset of this disease may lead to long-term sequelae if left untreated.
Electro-acupuncture (EA) is a treatment that combines manual acupuncture with electric stimulation. In China, many studies have claimed that EA has curative effects for PFP. EA can regulate the relationship between endothelin secreted by vascular endothelial cells and microcirculation, thereby regulating vasoconstriction or hemodynamics, ultimately treating PFP. It can also speed up the facial nerve’s conduction speed, promote the expression of nerve growth factor protein, and enhance facial nutrition.
Several studies have explored the effectiveness of EA in treating PFP. A study protocol published in 2015 aimed to use more intuitive and reliable detection techniques such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after applying EA. A total of 132 patients with Bell’s palsy were randomly divided into electro-acupuncture, manual acupuncture, non-acupuncture, and medicine control groups. However, the results of clinical studies on the efficacy and safety of EA for PFP have been inconsistent.
EA has been found to be potentially effective in shortening the disease course and reducing the occurrence of sequelae when applied at an early stage. Clinical studies have suggested that EA can reduce facial nerve edema, a common pathological feature in the acute phase of PFP.

Electro-acupuncture for facial nerve regeneration
Peripheral facial paralysis (PFP), or facial paralysis, is a condition characterised by the acute onset of unilateral weakness of the facial muscles. It is the most common facial nerve disorder, affecting 11.5 to 53.3 per 100,000 persons annually across multiple populations. The acute onset of this disease often results in sequelae that are challenging to eliminate without proper treatment.
Electro-acupuncture (EA) is a treatment that combines manual acupuncture with electric stimulation, providing a stable and continuous stimulus quantity. EA has been widely used in the treatment of intractable facial paralysis, and studies have found that it can play a role in nerve regeneration and repair after injury by promoting the growth of facial nerve axons. EA can also speed up the facial nerve's conduction speed and promote the expression of nerve growth factor protein.
Several studies have explored the status of EA among other treatments for PFP, with randomised controlled trials comparing EA with other treatments. These studies have observed and quantified the differences in outcomes through risk ratios and standardised mean differences, with 95% confidence intervals recorded.
One study protocol aims to use more intuitive and reliable detection techniques, such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves, to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after applying EA. This study will also verify the effectiveness of EA by combining neurological function scales.
EA has shown potential in treating PFP and promoting nerve regeneration, but further research and clinical trials are needed to establish its effectiveness and safety conclusively.

Electro-acupuncture for facial nerve paralysis
Peripheral facial paralysis (PFP), also known as facial paralysis, is a condition characterised by the acute onset of unilateral weakness of facial muscles. It is the most common facial nerve disorder, affecting 11.5 to 53.3 per 100,000 persons annually across multiple populations. The acute onset of this disease often leaves sequelae that are challenging to eliminate without proper treatment. Patients may experience numbness and paralysis on the affected side of the face, along with symptoms such as drooping mouth corners, drooling, and the inability to frown or knit their brows.
Electro-acupuncture is a treatment that combines manual acupuncture with electric stimulation, providing a stable and continuous stimulus quantity. It has been widely used in the treatment of intractable facial paralysis, and studies have explored its efficacy in this context. According to Traditional Chinese Medicine (TCM) theory, PFP is caused by a deficiency of vital qi, empty venation, and the invasion of pathogenic factors into the facial meridians, resulting in a loss of nourishment, blockage of qi, and muscle relaxation. The treatment principle involves dispersing pathogenic factors and regulating qi and blood by stimulating specific acupoints closely related to the facial nerve.
Electro-acupuncture has been found to regulate the relationship between endothelin secreted by vascular endothelial cells and microcirculation, thereby treating PFP by regulating vasoconstriction or hemodynamics. It can also speed up the facial nerve's conduction speed and promote the expression of nerve growth factor protein and brain-derived neurotrophic factor protein, enhancing facial nutrition and nerve regeneration after injury.
Several studies have been conducted to evaluate the effectiveness of electro-acupuncture in treating facial paralysis. These include randomised controlled trials, systematic reviews, and meta-analyses. However, the results of clinical studies on the efficacy and safety of electro-acupuncture for facial paralysis have been inconsistent. While some patients have obtained benefits or completely recovered, it is challenging to provide intuitive evidence beyond neurological function scales and electrophysiologic data. More recent studies aim to use more intuitive and reliable detection techniques, such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves, to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after electro-acupuncture treatment.
