Interferential Therapy: Treatment, Procedure, Cost and Side Effects

What is the treatment?

Transcutaneous electrical nerve stimulation, Interferential current therapy

How is the treatment done?

Interferential therapy is a type of therapy which is very effective and is used in relieving pain by various physiotherapic clinics. This helps to accelerate the process of self healing and getting a patient’s body free from pain and regain healthy physical conditions. In this therapy, the interferential current is produced on the skin, of the affected body part of the patient, with the help of interferential device by expert physiotherapist. This interferential current penetrates into the skin and reaches the underlying living muscle tissue.

This therapy involves an orthopaedic physical therapy setting. Generally this treatment is not given to patients having any severe health conditions. In cases of chronic pain in neck, shoulder, knee joint and back pain this treatment gives temporary relief of the location. This therapy is given to patients for 15 minutes in a single session.

Physiotherapy treatment plays a vital role in management of pain and some more physical conditions. The basic principles of interferential therapy are to utilise strong physiological effect in low frequency of electrical stimulations to muscle tissues and nerves too.

It is also described as transcutaneous application which involves alternating frequency of electric current for therapeutic purposes. A difference of 100Hz in current is required for the therapy. A mid frequency electrical signal is used to treat muscular strains and spasm. An interferential current therapy device is a most commonly found electrotherapy machine in today’s physiotherapy applications.

Who is eligible for the treatment? (When is the treatment done?)

The treatment of inferential therapy is done to the localized body part that is affected by muscle pain. This therapy is done with the help of a device known as inferential current therapy device. This device consists of four electrodes and a current intensity regulator. This therapy is mainly given to persons having pain in neck, knee, shoulder and back.

In this therapy, on the allotted portion of the body part of the patient, a lubricant known as electrode gel is applied at first. Then the four electrodes are placed in clover leaf pattern right angle to each other. Two intensity of current is passed through it with a difference of 100Hz in current input. The current passes through the skin and reaches the respective part of the body. The input of the current to the muscle produces some sensation and this sensation helps in self healing of the pain.

Patients having any other problem related to pain like inflammation and swelling, if receives this therapy may achieve relief too. This therapy also helps in restoring lost movements and helps in improving it.

Interferential therapy also helps in stimulating natural body hormones which triggers certain organs and heals the pain faster. However, this therapy is considered to be an effective treatment by many expert physicians.

Who is not eligible for the treatment?

Patients suffering from pain in various body parts are generally eligible for the treatment. This therapy is also used in sports medical field, such as athletes, who gets sudden pain due to any heavy exercise or any accidental event are sometimes provided this therapy by expert physiotherapists and has proved to be helpful for quick recovery. Any individual, above 12 years of age, can go for this therapy, only if it is prescribed by an expert doctor.

Are there any side effects?

This treatment is not eligible for athletes during their endurance training, but it can be applicable only after their training events get over. During pregnancy this therapy is generally not given, as it may cause harm to the mother and child both. This therapy is not used in any muscle regaining strategy. Infants or children below 12 years of age are generally not eligible for this therapy. However doctors suggests this therapy mainly for localized muscle pain only.

What are the post-treatment guidelines?

The current therapy does not have any such side effects as seen in most of the cases. But in some critical cases, or in times of pregnancy, if a person receives this current therapy then it might be risky and can be harmful also. It can also cause severe damage and difficulties if taken during pregnancy. In case of athletes, during their endurance training, expert physician recommends not to go for this therapy as it may be less helpful to them during the event. Though the risk factor of this therapy is less but one should always be self conscious to avoid any sort of problems.

How long does it take to recover?

The interferential therapy does not follow any such rules and regulations or guidelines for the patients after the treatment is done. In case of patients having any other problem in their body, must follow all the rules and guidelines as prescribed by their concerned doctors. However as the treatment is concerned with only localized muscle pain so the patient generally requires rest and sufficient sleep for quick recovery. Though no such guideline is found to be recommended in normal cases but it will always be helpful if a person stays fully conscious about his/her health to avoid any small or big problem regarding physical condition.

What is the price of the treatment in India?

The interferential therapy being just a temporary pain relief therapy takes a time duration of seven days minimum to get a healthy result for a patient. However due to less effectiveness it can be given to a patient continuously for 21 day to a month, for severe cases, as required. If a patient is suffering from any other physical problems then the time durations varies according to other required treatments.

Are the results of the treatment permanent?

The cost of the treatment in India varies from places to places. The price range generally starts from Rs. 120/- to Rs. 650/- per session. Various clinics provide this therapy at various price ranges. Price of this therapy is low in hospitals than in physiotherapy specialized clinics, and it mainly depends on how expert is a physiotherapist.

What are the alternatives to the treatment?

The interferential therapy is mainly used for localized muscle pain and is a temporary treatment for pain relief. However there is no such commitment of permanent recovery given to patients. The therapy is given just for a temporary healing of the affected area.

Do You Need Therapy?

Masters In Clinical Psychology

Do You Need Therapy?

Most of us face struggles at some point in our lives. These struggles may include stress at work, difficulty with a romantic partner, or problems with a family member. Alternatively, struggles may include emotional symptoms such as depression or anxiety, behavioral problems such as having difficulty throwing useless items away or drinking alcohol too often, and cognitive symptoms such as repetitive upsetting thoughts or uncontrolled worry. Sometimes, life's struggles can be eased by taking better care of yourself, and perhaps talking about the issues with a supportive friend or family member.

But there may be times when these steps don't resolve the issue. When this happens, it makes sense to consider seeking the help of a qualified licensed psychologist. How do you know if therapy is needed?

Two general guidelines can be helpful when considering whether you or someone you love could benefit from therapy. First, is the problem distressing? And second, is it interfering with some aspect of life?

When thinking about distress, here are some issues to consider:

  • Do you or someone close to you spend some amount of time every week thinking about the problem?
  • Is the problem embarrassing, to the point that you want to hide from others?
  • Over the past few months, has the problem reduced your quality of life?

When thinking about interference, some other issues may deserve consideration:

  • Does the problem take up considerable time (e.g., more than an hour per day)?
  • Have you curtailed your work or educational ambitions because of the problem?
  • Are you rearranging your lifestyle to accommodate the problem?

A “yes” response to any of these questions suggests that you might wish to consider seeking professional help. Remember that sometimes a problem might be less upsetting to you than it is to the people around you. This does not automatically mean that you are in the know and your friends or family are over-reacting to you. Rather, this situation suggests that you may wish to think about why the people who care about you are upset.

Clearly, the decision to enter into therapy is a very personal one. Numerous advances have been made in the treatment of psychological disorders in the past decade and many therapies have been shown scientifically to be helpful. As you think about whether therapy might be helpful to you, remember that many psychological problems have been shown to be treatable using short-term therapy approaches.

Learning more about different approaches to therapy might also help you to discern if one of them sounds like a good fit with your personality and approach to life. Given the range of therapeutic options that are available, you don't need to continue to struggle with a problem that is upsetting and/or getting in the way of other parts of your life. Help is available.

Popular Questions & Answers

Im 40 year old, facing back problems, will thermal therapy like crocin bed massager help me?

Erasmus Mundus Master in Adapted Physical Activity, MPT, BPTh/BPT
Physiotherapist, Chennai
This is a general low back ache and for this you can follow these measures: one keep a pillow right under the knee while sleeping, next is you can keep ice in the painful area for about 5--10 minutes, if pain still persists you can stretch your body by twisting the waist on both sides how we used to do in the school drill similarly you can try which will help you relax as well will reduce the pain. It looks like you are anaemic. If you have back pain after you sit for long hours then it is due to your haemoglobin levels as it is important to check that. Anaemia always leads to the symptoms of being tired and also having back / leg pain though there may not be any pathological reasons for back pain. Back pain / Sciatica: If you have low back pain and sciatica you can undergo intermittent pelvic traction where in your half of your body weight will be added in the electronic traction so that that would help you to reduce the pain, along with Interferential therapy stimulations which would help you to get relieved from the radiating pain. Apply ice for the pain to get subsided immediately. If you cannot go immediately for the physiotherapy treatment. Ice can be kept in the low back where you have back pain. It is suggestible to wear Lumbo sacral belt which would help you to build the abdominal muscle tone which itself would make you feel better. You can also wear MCR chappals which would help you to have less weight falling in the painful back.

Dermatologist, Bangalore
Acne is a common skin condition affecting teenagers as well as adults. Severity varies from person to person so does treatment. Patient may have comedones commonly called black heads and white heads, papules also called bumps, pus filled lesions, nodules and cysts. Patients may have any combination of these. So only we suggest donot self medicate as it is difficult for anyone other than dermatologist to tell what treatment protocol you need. Treatment of pimple marks and scars also needs specialized approach. Consult a qualified dermatologist.

PRP Therapy And Prolozone Therapy
Good evening friends.

This is Dr. Nilay Shah. I run a medical tourism company, called as positive medical services. It s a medical tourism company, which provides one stop solution for many medical problems. The unique part of us, we are different as compared to modern medicine. We are into tolerant therapies. Various alternative therapies which I practised like chelation, ozone, PRP, prolozone, Vitamin C, etc. today we are going to talk about PRP therapy and prolozone therapy. Both of these therapies are very useful in ligament test and tender problems. PRP. That is the first thing about which we are going to talk about. The word itself, PRP stands for Platelet Rich Plasma, Platelet Rich Plasma means its plasma which is rich in platelet. That means that is very useful in producing growth factors, which are produced naturally in the body. The way we do is we draw a certain amount of blood from the patient s vein, now this drug is taken into centrifugation machine. And we Centrifuge it. The moment we centrifuge it, there is a layer which is separated out, which is full of platelets. This layer, we take it in a syringe. And we inject at the place where there is a ligament tear or a tendon problem. Now how does it work? It works by producing growth factors, as I said earlier. These growth factors help in natural rebuilding or tissue repair. Most of the patients which we get for PRP are patients who are asked to go for arthroscopy or surgery. This is a natural way. Where our own tissue is helping it to rebuild again without any surgery or any other invasive procedures. And the best part is since you are using your own blood so there is no question of any side effects. Now, the next thing we are gonna talk about is Prolozone. Prolozone is very much similar to PRP, but the only difference is we are using a polorofent. Polorofrent is something like an irritant which produces a second inflammation to already a tissue which is already injured or damaged. Polorofrent and ozone, when we combine these together it is called as prolozone. Again the mechanism is very such similar to PRP. Whereby we are helping the tissue to get it repaired. The only difference is, in PRP what we were doing is we were using our own tissue for the repair, but here we are using prolofent, giving a second inflammation which is already injured and thereby giving it a second healing. Now, both this PRP and prolozone are very useful. In major cases where patients comes in a lot of pain, they don t want to go for a surgery, they are diabetic and there are certain complications for a surgery. This is the easiest and the safest way for getting the tissue repaired as compared to the convention medicine where you go for an arthroscopy or a tissue repair through a surgery. And since these therapies don t have any side effects as compared to convention medicine, people have been opting for it. And there is one of the major reason, throughout the world these therapies are getting popular. I hope I have been quite informative in explaining you guys PRP and proozone therapy. For more information. If you all at wich to contact me, you can contact me through Lybrate.

Thank you very much.

Panchakarma Therapies
Hi, I am Dr Sowmya Nair and I am an Ayurvedic physician with more than 13 years of experience in Ayurvedic treatments. I am specialised in Ayurvedic therapies. So, today I am going to speak about Panchakarma therapies.

In Ayurveda, Ayur means "life" and veda means "science". IN Ayurveda, we are treating patients according to the doshas i.e. vaat, pitt and cough. If a person has any imbalance between the vaat, pitt and cough then they will suffer from diseases. In order to balance the doshas, we are doing Panchaklarma therapies.

Panchakarma means 5 karmas. It is the main treatment in Ayurveda. Panch means "five" and karma means "treatment". There are

Rakta moksha
These are the main treatments in Ayurveda. With these therapies, our body will be healthy and it helps in maintaining all the doshas- vaat, pitt and cough.

For problems like- sinusitis, chronic sinusitis, psoriasis, we do Vamana therapy.
Virechana is a loose motion therapy. In the pitta problems also we do Virechana therapy.
Nasya is the main treatment for the sinusitis, allergic rhinitis related problems.
Basti is the main treatment. It cures all the vada related diseases. LIfestyle diseases liek spondylitis, cervical spondylitis, lumbar spondylitis, slip disc cases, multiple psoriasis. In this, we are giving medicated decoction and medicated oil through anal route.
The last is the Rakta moksha. It is a blood ducting. It is a Kerala therapy and it is a Leech therapy. Leech therapy is very good for all pitt dosh related problem and skin related problems.
Nowadays the slip disc and osteoarthritis are very common. In osteoarthritis, there is degenerative changes in bones. If it affects your neck, it is called cervical spondylitis. If it affects your back, it is called Lumbar spondylitis. If it affects your knees, it is called ankylosing spondylitis. Osteoarthritis of knees are very common now a days.

How to prevent Osteoarthritis of knees?

Maintain your diet. Avoid eating junk food and oily food in order to maintain your body weight.
Do regular exercises. Do walk and yoga asanas to help preventing Osteoarthritis.
Maintain the right postures.
If slip disc affect the neck, you will have pain and numbness. If it affects the cervical, you will get cervical pain, neck stiffness, neck pain. If it affects the Lumbar region, then you will have difficulty in movements and pain in both the legs. For such problems, we have excellent treatment in Ayurveda.


In Osteoarthritis problems, we are doing janu basti, janu pichu, abhyangam, elakiri, podikizhi. All these treatments are very good to cure Osteoarthritis.

If it is cervical disc related problem, then we give greeva basti, greeva picchu, nasyam are very good for this problem.

We treat Lumbar disc related problem with Kadi basti, kadi picchu, abhyangam.

These are the main treatments for all the diseases.
