What Is Laser Therapy (LLLT)?
Low-level laser therapy (LLLT), also known as photobiomodulation, uses red and near-infrared light at specific wavelengths (typically 630–1000 nm) to penetrate tissue and stimulate biological processes at the cellular level. Unlike surgical lasers, LLLT does not cut or heat tissue — it delivers photonic energy that is absorbed by mitochondria (the cellular powerhouses), increasing ATP production and accelerating a wide range of healing and anti-inflammatory processes. It is painless, safe, and produces no radiation.
How Laser Therapy Reduces Pain and Inflammation
LLLT reduces pain through multiple mechanisms: it decreases levels of prostaglandins and cytokines that drive inflammation, modulates the activity of pain-sensitive C-fibres and A-delta nerve fibres, and promotes endorphin release. Increased ATP production in cells at the treatment site accelerates clearance of inflammatory metabolites and stimulates tissue repair. The anti-inflammatory effects are comparable to NSAID medication in some clinical studies, but without systemic side effects. Regular treatment progressively reduces both acute and chronic pain levels.
What to Expect During Treatment at Realign Rehab Clinic
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri applies the laser handpiece directly to the skin over the painful area using a systematic grid pattern to ensure even energy delivery. Both you and the treating therapist wear protective eyewear throughout. Sessions are quick — five to fifteen minutes depending on the treatment area — and completely painless. A typical course involves six to twelve sessions, and many patients notice reduced pain and improved mobility after the third or fourth session. LLLT combines well with manual therapy, exercise rehabilitation, and other electrotherapy modalities.
Benefits of Laser Therapy for Pain Relief
- Reduces acute and chronic inflammation at the cellular level
- Modulates pain pathways without oral medication
- Accelerates tissue repair in the treated area
- Fast, painless sessions compatible with ongoing rehabilitation exercise
Is Laser Therapy Safe?
LLLT has an excellent safety record and is approved for musculoskeletal use worldwide. The primary precaution is eye protection for both patient and therapist, which is always provided at Realign Rehab Clinic. It should not be applied over active malignancy, directly over the thyroid gland, or over the pregnant uterus. Photosensitive patients or those on photosensitising medication require individual assessment. Dr. Vaishali Suri reviews all precautions before every course of laser therapy.
Frequently Asked Questions
Does laser therapy hurt?
LLLT is completely painless. Most patients feel nothing at all during treatment, or occasionally a very mild warmth over the treatment site. There is no burning sensation, as the laser energy used in LLLT is far below the threshold required to heat tissue.
How many sessions of laser therapy will I need?
Six to twelve sessions is the standard course for most pain conditions, delivered three times per week initially. Chronic pain with significant central sensitisation may benefit from twelve to eighteen sessions. Dr. Vaishali Suri reassesses pain scores and tissue response at each visit.
Is laser therapy available in Faridabad?
Yes. Laser Therapy (LLLT) 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.
