What Is IFT (Interferential Therapy)?
Interferential therapy is an advanced form of electrical stimulation used in physiotherapy to treat pain and accelerate tissue healing. Two medium-frequency currents intersect within the body to produce a lower-frequency therapeutic effect that can penetrate deep muscle tissue without causing discomfort at the skin. It is widely used in sports rehabilitation, post-injury recovery, and pre-competition preparation to maintain muscle health.
How IFT Aids Muscle Recovery and Sports Injuries
After a muscle strain or overuse injury, the affected fibres become inflamed, fill with metabolic waste products, and enter protective spasm. IFT increases local blood flow to deliver oxygen and nutrients, activates lymphatic drainage to clear waste, and produces rhythmic electrical stimulation that reduces spasm and restores normal motor recruitment patterns. The combined effect accelerates the transition from the inflammatory phase to the tissue-remodelling phase of healing.
What to Expect During Treatment at Realign Rehab Clinic
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri applies the four IFT electrodes over the injured muscle group. The frequency and sweep pattern are selected based on whether the goal is pain relief, muscle re-education, or oedema reduction. Sessions run for 20–30 minutes and are often combined with manual therapy, ultrasound, or targeted exercise. For an acute sports injury, IFT may begin as early as 24–48 hours after the incident. Athletes typically receive three to five sessions per week in the early recovery phase.
Benefits of IFT for Muscle Recovery
- Accelerates clearance of metabolic waste from injured muscle tissue
- Reduces pain and protective spasm to allow earlier active rehabilitation
- Stimulates muscle re-education after injury-related inhibition
- Suitable for a wide range of sports injuries including strains, contusions, and overuse conditions
Is IFT Therapy Safe?
IFT has an excellent safety profile and is routinely used with competitive athletes. It should not be applied directly over acute haematomas in the first 24 hours as it may increase bleeding. Patients with pacemakers, implanted stimulators, or active skin infections at electrode sites should not receive IFT. All patients at Realign Rehab Clinic are screened by Dr. Vaishali Suri before treatment commences.
Frequently Asked Questions
Does IFT therapy hurt?
IFT is not painful. Athletes describe it as a deep buzzing or pulsing sensation that can feel quite pleasant, particularly over fatigued or overworked muscles. The intensity is fully adjustable and kept within a comfortable range throughout the session.
How many sessions of IFT therapy will I need?
Acute sports injuries typically need four to eight sessions, depending on severity. Athletes returning from competition or heavy training loads benefit from maintenance IFT alongside their exercise programme to manage fatigue and prevent re-injury.
Is IFT therapy available in Faridabad?
Yes. IFT (Interferential Therapy) is available at Realign Rehab Clinic, NIT-5 Faridabad. Dr. Vaishali Suri uses this technique as part of a comprehensive physiotherapy programme. Call +91 9818185589 to book.
