Interferential Therapy (IFT) in Indirapuram

Interferential therapy uses two medium-frequency currents that cross inside the tissue to produce a low-frequency effect deeper than a standard TENS unit reaches. It's a pain-relief tool. It works best as a way to calm symptoms enough for you to do the treatment that actually changes things.

How IFT works

Four electrodes are placed around the painful area in a crossing pattern. Two currents of slightly different frequencies meet in the tissue, and where they overlap they produce a beat frequency that stimulates sensory nerves. The skin feels a comfortable tingling rather than the sharper sensation of low-frequency current.

The main effect is on pain signalling. Stimulating large sensory nerve fibres reduces how strongly pain messages get through at the spinal cord, and some settings may encourage the body's own pain-relieving chemicals. Relief usually lasts from a few hours to a day.

What it's used for

IFT is most useful when pain is high enough to stop you exercising or moving normally. Acute back and neck pain, flare-ups of arthritis, and painful tendons are typical. It gives a window of reduced pain in which exercise and mobility work can be done more comfortably.

It isn't a cure for structural problems, and research doesn't support using it on its own for long-term results. We use it for a limited number of sessions and reduce it as your active programme takes over.

Who shouldn't have IFT

We don't use it over a pregnant abdomen or pelvis, near a pacemaker or other implanted electronic device, over active cancer, over areas of deep vein thrombosis, over broken or infected skin, or where sensation is significantly reduced. Tell us about any implants or medical conditions before treatment.

Medical note

This page is general information, not a diagnosis. Treatment is planned after an in-person assessment by a physiotherapist, and we refer you to a doctor where symptoms need medical review first. If you have sudden weakness, loss of bladder or bowel control, chest pain or severe unexplained pain, seek emergency care.

Frequently asked questions

Does IFT hurt?

No. It feels like a strong but comfortable tingling or buzzing. The intensity is adjusted to your comfort.

How long is a session?

Usually 10 to 20 minutes, as part of a longer session that includes exercise or manual therapy.

Is IFT better than TENS?

It reaches deeper and is more comfortable at higher intensities, but for pain relief the two are broadly similar. TENS has the advantage of being usable at home.

What is Interferential Therapy (IFT)?

Interferential therapy (IFT) is an electrotherapy that uses two medium-frequency currents crossing in the tissue to produce deep, comfortable pain relief.

Who can benefit from Interferential Therapy (IFT)?

People with back, neck, knee or shoulder pain that is stopping them moving or exercising normally.

What conditions can Interferential Therapy (IFT) help with?

It commonly helps with lumbar spondylosis, cervical spondylosis, disc bulge, knee osteoarthritis, shoulder impingement and plantar fasciitis. Arthritis flares and painful tendons are also common uses.

What are the benefits of Interferential Therapy (IFT)?

Drug-free pain relief that lasts hours to a day, making exercise and movement easier.

How does Interferential Therapy (IFT) work?

The crossing currents stimulate sensory nerves deep in the tissue, which reduces how strongly pain signals travel to the brain.

What happens during an Interferential Therapy (IFT) assessment?

We check where pain is, skin sensation, and screen for implants, pregnancy and other contraindications.

What happens during an Interferential Therapy (IFT) session?

The area is positioned comfortably, Interferential Therapy (IFT) is applied for about 10 to 20 minutes within a longer session, and it is usually followed by exercise such as pelvic tilts and quadriceps sets, because it works best as part of an active plan.

What treatments are used with Interferential Therapy (IFT)?

It is usually combined with TENS therapy, ultrasound therapy, manual therapy and heat therapy (thermotherapy), depending on your assessment and how you respond.

What exercises are commonly used with Interferential Therapy (IFT)?

Common exercises include pelvic tilts, quadriceps sets, passive, assisted and active range of motion and isometric exercises. They start at a comfortable level and are progressed as you improve.

How long does an Interferential Therapy (IFT) session take?

A session usually takes 10 to 20 minutes within a longer session.

How many Interferential Therapy (IFT) sessions might be needed?

Usually a few sessions while pain is high, reducing as exercise takes over.

How often should Interferential Therapy (IFT) sessions be scheduled?

Two to three times a week during painful phases.

Can Interferential Therapy (IFT) help reduce pain?

Yes. Pain relief is its main purpose.

Can Interferential Therapy (IFT) improve mobility?

Indirectly, by reducing pain enough to move.

Can Interferential Therapy (IFT) improve strength and flexibility?

No. Exercise builds strength. Strength and flexibility come from the exercises your physiotherapist sets alongside it.

Can Interferential Therapy (IFT) be provided at home?

Yes. Our therapists carry portable IFT units for home visits. We visit homes across Indirapuram, Vaishali, Vasundhara, Noida and Ghaziabad; see home visit physiotherapy.

Is Interferential Therapy (IFT) suitable after surgery or injury?

Yes, for post-operative pain, avoiding metal implants in the current path.

Is Interferential Therapy (IFT) suitable for older adults or children?

Yes for older adults; rarely needed in children.

What precautions should be considered with Interferential Therapy (IFT)?

Not used over a pregnant abdomen, with pacemakers, over cancer, DVT, broken skin or areas without sensation.

When should I consult a physiotherapist about Interferential Therapy (IFT)?

When pain is high enough to stop you moving or exercising. You can book an assessment at our Indirapuram clinic or ask for a home visit.
