What Is TENS Therapy?
Transcutaneous Electrical Nerve Stimulation (TENS) delivers low-level electrical pulses via electrode pads placed on the skin. These pulses stimulate sensory nerve fibres, which compete with and override pain signals travelling to the brain — a mechanism known as the gate control theory of pain. At higher intensities, TENS also triggers the release of endorphins, the body's natural pain-killing chemicals. It is portable, drug-free, and can be used in a clinic or at home with a prescribed device.
How TENS Treats Chronic Pain and Nerve Pain
Chronic pain conditions involve sensitised pain pathways that continue to fire long after tissue damage has healed. Nerve pain (neuropathic pain) from compressed, damaged, or irritated nerves adds a burning, shooting, or electric quality. TENS specifically targets these sensitised pathways by producing a constant barrage of non-painful sensory input that effectively drowns out the pain signals. Regular TENS use can also reduce central sensitisation over time, lowering baseline pain levels progressively.
What to Expect During Treatment at Realign Rehab Clinic
Dr. Vaishali Suri at Realign Rehab Clinic, NIT-5 Faridabad, will identify the most effective electrode placement for your specific pain pattern and set the device parameters (frequency, pulse width, intensity) for your condition. Clinical sessions last 30–45 minutes. For conditions like fibromyalgia, post-herpetic neuralgia, or chronic regional pain, Dr. Vaishali Suri may also teach you to use a home TENS unit so you can continue treatment independently between clinic visits for maximum benefit.
Benefits of TENS for Chronic Pain
- Drug-free pain relief with no systemic side effects
- Reduces reliance on oral analgesics and anti-inflammatory medication
- Can be used continuously throughout the day for persistent pain
- Empowers patients to self-manage pain at home with minimal risk
Is TENS Therapy Safe?
TENS is one of the safest pain-relief tools available. It should not be used over the carotid sinuses (neck), across the chest in patients with heart conditions, over broken skin, or in patients with epilepsy. It is not suitable during pregnancy over the abdomen or lower back. Patients with pacemakers or implanted electrical devices must not use TENS without medical clearance. Dr. Vaishali Suri ensures all contraindications are checked before prescribing TENS.
Frequently Asked Questions
Does TENS therapy hurt?
TENS should not be painful. The sensation is a gentle tingling, buzzing, or tapping that is adjusted to a comfortable level. If stinging or burning occurs, the electrodes need repositioning or the intensity needs reducing. Most patients find TENS relaxing and look forward to sessions.
How many sessions of TENS therapy will I need?
Chronic pain management typically involves eight to twelve clinic sessions, with ongoing home use of a TENS device prescribed by Dr. Vaishali Suri. Some patients benefit from maintenance clinic top-ups monthly or quarterly alongside their exercise programme.
