What Is TENS Therapy?
Transcutaneous Electrical Nerve Stimulation (TENS) applies mild electrical pulses through electrode pads on the skin to modify the way pain signals are processed by the nervous system. Two well-established mechanisms are involved: the gate control effect (sensory stimulation blocking pain signals at the spinal cord level) and endorphin release (natural opioid production triggered by specific TENS frequencies). The therapy requires no medication, no needles, and has no systemic side effects.
How TENS Treats Back Pain and Sciatica
Back pain — whether from disc prolapse, facet joint irritation, or muscle strain — generates pain signals that travel up the spinal cord to the brain. Sciatica adds radiating nerve pain down one or both legs. TENS electrodes placed on the lower back or along the sciatic nerve distribution produce strong sensory input that interrupts this pain transmission. High-frequency TENS (80–100 Hz) gives rapid relief through gate control, while low-frequency TENS (1–5 Hz) promotes endorphin release for longer-lasting analgesia. Dr. Vaishali Suri selects the peak parameters for each patient's presentation.
What to Expect During Treatment at Realign Rehab Clinic
- Consultation — Dr. Vaishali Suri reviews your diagnosis and confirms this technology is appropriate
- Area preparation — the treatment site is cleaned and gel or coupling medium applied
- Parameter setting — frequency, intensity, and duration are calibrated for your specific condition
- Treatment delivery — the device is applied and you guide feedback on comfort throughout
- Post-treatment check — immediate response assessed; soreness and redness are normal
- Home advice — activity guidance and what to expect over the next 24–48 hours
- Follow-up plan — number of sessions and progress markers agreed before you leave
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri positions electrodes over the painful lumbar region, alongside the spine, or over the buttock and thigh in sciatica cases. The device is switched on and the intensity gradually increased until you feel a strong but comfortable tingling. Sessions last 30–45 minutes. TENS is often combined with manual therapy, spinal mobilisation, or core stability exercises to address the underlying cause of the back pain alongside symptom relief.
Benefits of TENS for Back Pain and Sciatica
- Immediate pain relief that allows earlier movement and rehabilitation
- Reduces the need for NSAID or opioid medication
- Safe for use in the presence of disc pathology and nerve irritation
- Can be continued at home with a prescribed portable unit between clinic visits
Is TENS Therapy Safe?
TENS is safe for most adults with back pain and sciatica. It should be avoided over the abdomen or lower back during pregnancy, in patients with epilepsy, or in those with implanted spinal cord stimulators or pacemakers. Electrode placement directly over the spine is avoided. Dr. Vaishali Suri reviews every patient's medical history before prescribing TENS.
Frequently Asked Questions
Does TENS therapy hurt?
TENS should feel comfortable throughout. The tingling sensation in the back or down the leg can initially feel unfamiliar but is not painful. The intensity is kept below the motor threshold (the point at which muscles start to twitch) for pure pain-relief TENS. Any discomfort should be reported immediately to Dr. Vaishali Suri for electrode repositioning.
How many sessions of TENS therapy will I need?
Most patients with back pain see improvement after four to eight clinic sessions. Sciatica related to disc compression may require a longer programme alongside nerve mobilisation techniques. Home TENS use is often recommended for pain management between clinic appointments.
Is TENS therapy available in Faridabad?
Yes. TENS Therapy is available at Realign Rehab Clinic, NIT-5 Faridabad. Dr. Vaishali Suri uses this technique as part of a thorough physiotherapy programme. Call +91 9818185589 to book.
