About FSN

Fu’s Subcutaneous Needling (FSN) is a modern acupuncture technique, which was invented by Dr Zhong-hua Fu, a Chinese doctor, in 1996. This technique uses a modified acupuncture needle FSN Trocar Acupuncture Needle to stimulate subcutaneous areas where nearby trigger points, taut or tightenedmuscles (TMs), in order to treat musculo-skeletal conditions as well as many other medical conditions, for instanceavascular necrosis (AVN), AMD, Parkinson’s disease, etc. With the characters of much less pain of the patient and instant effect of pain relieving, the patients quite often describe the FSN as “magic needle”.” unbelievable effects”.

more info about FSN

FSN Trocar Acupuncture

The FSN needle is a modified trocar needle and has been patented in China. There are three parts to the needle: soft casting tube, or canulae; protecting sheath, and solid needle. The solid needle is 31 mm in length and 1 mm in diameter. Each needle is individually packaged and sterilized with ethylene oxide gas.This Trocar Acupuncture has been patent in China in 1999. It also has passed CE Marking requirement (Shanghai International Holding Corp GmbH Eiffestrase 80. D-20537, Hamburg, Germany)

What are the difference between TA and FSN

Traditional Acupuncture (TA) is to use fine needles inserting at the specific points of meridians in the body for therapeutic or preventative purposes.

TA involves by inserting needles to penetrating skin, subcutaneous and muscular tissues and then stimulating the points.  Patients will experience different feelings such, Chinese medicine called “De Qi”, as heaviness, tingling, mild soreness, etc.Once needles are put in, patients will stay still for around 30mins for the effect. 

FSN is originated from Traditional Chinese Acupuncture and developing on basic medical science. 

FSN’s needle only reach to subcutaneous tissue.This technique has much less pain and less sensation on the patients.Instead of staying still, the movements for the strained muscles are involved while manipulating needle, which can produce an incredible pain-relieving effect instantly.

Dr Zhonghua Fu

Dr Zhonghua Fu read his bachelor degree in medicine at Nanjing University of Traditional Chinese Medicine(NJUCM) in 1990. He then obtained his master’s degree at NJUCM in 1999. His dissertation was on acupuncture techniques. 

 

He worked at No1 Military University of Medicine and Hospital as a clinician, lecturer, and then  professor from 1994 to 2006. It was from there he found that stimulating subcutaneous level with acupuncture needles have more healing effect, and invented Fu’s Subcutaneous Needling technique in 1996. 

 

Dr. Fu did his another postgraduate degree in biology at Nanjing University, and obtained his PhD in 2007, then he set up FSN Acupuncture Institute, the clinical, research and training centre in Nanjing, China.

 

Over the last 20 years, Dr. Zhonghua Fu has showed his great talent, interest and enthusiasm in modern acupuncture field, and gained a large number of research results on studying of the effect and scientific mechanism of FSN acupuncture. He has been making his effort to bridge acupuncture and modern conventional medicine. He has made a great deal of research findings including “Tight Muscle Theory” and obtained many patents for treatment appliances including FSN acupuncture needle and its accessory device. He has published over 10 works in medicine and 50 papers in medical journals and lectured in China and abroad.

 

At the present, Dr. Fu is the head of Nanjing FSN Institute; professor of Nanjing University of TCM; Guest Professor of Guangzhou University of Chinese Medicine; Acupuncture consultant of Beijing University of Chinese Medicine; Chairman of FSN Academic Committee of Clinical Department in Association of Acupuncture-Moxibustion of China; Chairman of FSN Committee of World Federation of Chinese Medicine Society. 

 

Dr. Fu currently reside in Nanjing, China with his wife and daughter.

Clinical research team

During last 15 years, FSN has attracted over thousands Chinese doctors and clinicians. A clinical research team has been set up. These young scholars and researchers are located all over China. They either run private practice or working at state owned hospitals. 

Most of them run FSN practice exclusively which enabled them to collect clinical data and gaining accurate information of clinical effectiveness rate to certain conditions. When a disorder or condition is tested by these practitioners, and an 80-90% of effectiveness rate or instant symptoms relieving are all agreed by these clinicians, then they claim that FSN can treat this disorder or condition. 

What can FSN help?

Generally speaking, FSN can help all the conditions which traditional acupuncture helps, but more effective and quicker response than traditional acupuncture. Particularly, FSN has a very positive result for variouspain relief, and high success rate for some other conditions.In FSN practice, it is trained to improve the most painful conditions and complaint on the spot, therefore, FSN is more effective. That is why some of patients call this “Big needle, but Magic needle”.

Is FSN safe?

Absolutely! 

FSN is much safer than traditional acupuncture and other new needling techniques, for the simple reason that it does not reach the muscles or penetrate the deep fascia layers, but only stops at the subcutaneous layers. 

FSN treats the afflicted area or organ by stimulating its healthy counterpart, thus making it undoubtedly not only safer than traditional acupuncture but also much less painful and sensitive, since there is very few nerve endings in subcutaneous layer. 

However, one should also remember that FSN, like all the other needling techniques, may sometimes have some temporary minor adverse effects, such as a couple of drops of blood where the needle perforates the skin or, in rare occurrences, a short bout of dizziness.

Does FSN painful?

Not really! 

Although FSN needle is slight thicker than conventional acupuncture needle, as it is inserted by an applicator, the insertion is almost painless. In addition, as FSN only use one or two needles, plus patients requested no sensation (de-qi), while convention acupuncture uses 10-20 needles and requesting patients have sore or heaviness sensations. That is why some children would choose FSN rather than conventional acupuncture.

Why Stimulate the subcutaneous layer?

  • This is to do with its special structure and composition, subcutaneous layer is unique! It is a sort of connective tissue proper, including adipose tissue and loose connective tissue.  Because adipose tissue is an inert tissue which doesn’t respond to the surrounding environment change, the effect of FSN acupuncture is fully from loose connective tissue which contains the flowing special cells and interstitium:
  • Fibroblast: generating fibre, responding to infection or trauma and regenerating fibres for repairing and renewing tissues. 
  • Macrophage:phagocytizing, removing pathogenic substances and cell residues; secreting cytokine; adjusting immune response.  
  • Mast Cell: participating anaphylactic reaction.
  • Plasma Cell: from activated B cell, and can generate immunoglobulin and cytokine, participating in humoral immunoresponse.
  • Leukocyte (white blood cell): Having ability of phagocytosis. Some of them also secrete interleukin (IL), IFN, TNF and participate in adjusting the immune response.
  • MSC: mainly stays in subcutaneous layer, once activated, it can adjust immune response and participate in the process of inflammatory reaction, restoration and regeneration. 
  • Adipocyte: storing fat.
  • Interstitium is described as the largest “organ” which consists fibre (collagenous, elastic and reticular fibres) and ground substance in human body, covers the whole body and connects every organ and tissue. This dynamic, wide spread, fluid-filled space is a pathway for disease spreading such as cancer metastasis, and importantly, immune substances also have to traffic into this pace, interact and pass through when inflammatory conditions occur.

 

Therefore, the stimulation in subcutaneous connective tissue from FSN needle might activate the cells above and interstitium (collagenous fibre),  and cause the local or whole body immunoresponse including inflammatory, repair and regeneration reaction through interstitium, and this would result the body recovery from the damages and illnesses.

How does FSN work

FSN needle is a presterilizeddisposable solid stainless-steel needle imbedded partially with a casing tube (cannula). The needle is accurately delivered into subcutaneous layer by an applicator device. Once the needle is in subcutaneous layer, the tip of needle is withdrawn and rest into the casing tube, then the manipulation of a horizontal swiping from side to side is performed.

Combined with the designated movement of the tightened muscles and continues needle manipulation, after few minutes, the tightened muscles should have been relaxed and original complaint, such pain will be reduced or disappeared.

Let’s take foot heel pain as an example, in conventional medical term a heel pain is described by doctors as “Plantar fasciitis”, which means inflammation of your plantar fascia. Normally you may be prescribed by anti-inflammatory medicine (NSAIDs) or steroids injection on the painful spot. While on FSN, we may check the muscles tensions around calf or leg, normally we will be able to find tightened muscles around Gastrocnemius or Soleus muscles. Then, a FSN needle is inserted at between skin and muscles, i.e. subcutaneous level, of calf or above external malleolus, followed by some manipulations conducted by practitioner and yourself. After few munities treatment, you are required to test the pain by press and walk on foot for few steps, you may be able to find the degree of pain has changed.

Fu’s Subcutaneous Needling Association of Europe (FSNAE) was established in January 2018 in the UK.The purpose of FSNAE is to have a platform to discuss and explore the FSN.
