IFT 

*IFT physiotherapy* = *Interferential Therapy*. It’s a non-invasive electrotherapy used a lot in clinics for pain relief and tissue healing.

How it works

An IFT machine sends 2 medium-frequency electrical currents, usually around 4000 Hz, that intersect inside your tissues. Where they cross, they create a low-frequency “beat” current, typically 0-250 Hz.

This low-frequency current:

1. *Blocks pain signals* via the gate control theory – it stimulates large nerve fibers to “close the gate” to pain.

2. *Triggers endorphin release*, your body’s natural painkillers.

3. *Boosts blood flow and reduces swelling* by causing vasodilation and muscle contractions.

Sessions usually last 10-20 mins and feel like a gentle tingling/buzzing.

What it’s used for

Clinics use IFT for both acute and chronic issues:

- *Musculoskeletal pain*: low back pain, neck pain, knee pain, tennis elbow, shoulder pain, arthritis, OA

- *Muscle spasms and stiffness*

- *Post-surgical and post-injury pain*

- *Edema/swelling management*

- *Neuralgia, sciatica, diabetic neuropathy*

Key benefits

- *Pain & inflammation reduction* without drugs

- *Better circulation* delivering oxygen/nutrients to tissues for faster healing

- *Muscle relaxation* and reduced spasm

- *Deep penetration* with more comfort than TENS, so it reaches deeper tissues

When to avoid it

Don’t use IFT over:

- Pacemakers/implanted devices, cancerous lesions, thrombophlebitis

- Pregnancy on abdomen/lower back, eyes, carotid sinus, open wounds

Also use caution if you’re on opioids/tramadol, as IFT may potentiate effects.

What to expect

The physiotherapist places adhesive electrodes around the painful area. You’ll feel a comfortable tingling. Intensity is adjusted to “strong but comfortable”. Many people notice relief and better mobility after a few sessions.

It’s usually part of a bigger rehab plan that includes exercise and manual therapy, not a standalone cure.
