What Is IFT (Interferential Therapy)?
Interferential therapy uses two slightly different medium-frequency electrical currents that cross each other inside the tissue, creating a therapeutic low-frequency interference signal deep in the body. Unlike TENS, which acts at the skin surface, IFT penetrates several centimetres into muscle and joint tissue. The result is strong pain relief, muscle relaxation, and improved circulation without discomfort at the skin electrode sites.
How IFT Treats Back Pain and Muscle Spasm
Back pain is frequently perpetuated by protective muscle guarding — involuntary spasm in the erector spinae and deep paraspinal muscles. IFT's deep alternating current stimulates sensory nerve fibres to block pain signals (gate control mechanism) while simultaneously causing the spasming muscle to fatigue and relax. It also promotes local blood flow, removing the metabolic waste products that sustain muscle pain and stiffness.
What to Expect During Treatment at Realign Rehab Clinic
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri positions four electrodes around the painful area of your back. The machine delivers a mild, comfortable tingling or buzzing sensation. A session typically lasts 20–30 minutes, and most patients feel significant relief during or immediately after the first session. For acute back pain, six to eight sessions may be sufficient; chronic cases may benefit from a longer programme combined with manual therapy and exercise rehabilitation.
Benefits of IFT for Back Pain
- Deep tissue pain relief without medication
- Rapid reduction of protective muscle spasm
- Improves local circulation and accelerates tissue healing
- Comfortable and non-invasive, suitable for acute and chronic back pain
Is IFT Therapy Safe?
IFT is one of the safest electrotherapy modalities used in physiotherapy. It is not suitable for patients with cardiac pacemakers, implanted electrical devices, active malignancy in the treatment area, or open wounds under the electrode sites. It should be avoided during pregnancy over the lumbar or abdominal region. Dr. Vaishali Suri screens all patients before each treatment course.
Frequently Asked Questions
Does IFT therapy hurt?
IFT is generally very comfortable. Most patients describe a gentle tingling or buzzing sensation that can be adjusted in intensity. Unlike some electrical therapies, IFT does not cause skin discomfort because the medium-frequency carrier current passes through surface tissue easily.
How many sessions of IFT therapy will I need?
Acute back pain often responds within four to six sessions. Chronic or recurrent back pain typically requires eight to twelve sessions as part of a broader rehabilitation plan including exercise and manual therapy.
