What Is Laser Therapy (LLLT)?
Low-level laser therapy (LLLT) uses targeted red and near-infrared light to stimulate cellular energy production and healing processes in injured tissue. The light energy is absorbed by mitochondria within cells, increasing ATP output and activating signalling pathways that reduce inflammation, promote tissue repair, and enhance muscle recovery. It is widely used in professional sports medicine to speed return to training after muscle strains, ligament sprains, tendon injuries, and contusions.
How Laser Therapy Treats Sports Injuries and Aids Muscle Recovery
Sports injuries generate acute inflammation that, if uncontrolled, can prolong healing and increase scar tissue formation. LLLT modulates the inflammatory cytokine cascade, reducing excess inflammation while preserving the pro-healing aspects needed for repair. In muscle injuries specifically, LLLT reduces satellite cell death, improves myofibre regeneration, and decreases oxidative stress in damaged tissue — all of which shorten recovery time and improve the quality of repaired tissue. Evidence supports its use in hamstring strains, calf tears, quadriceps contusions, and rotator cuff tears.
What to Expect During Treatment at Realign Rehab Clinic
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri will assess the injury, identify the tissue involved, and select the appropriate wavelength and dose parameters. The laser handpiece is applied directly to the skin over the injured area in a systematic grid. Treatment is painless and takes five to fifteen minutes depending on the size of the injury. In the acute phase (first 24–72 hours), LLLT is ideal because it provides biological benefit without compression, movement, or heat that could aggravate the injury. It is combined with progressive rehabilitation exercise as the injury moves into the subacute and remodelling phases.
Benefits of Laser Therapy for Sports Injuries
- Reduces acute post-injury inflammation and pain rapidly
- Accelerates muscle and tendon fibre repair for faster return to sport
- Reduces the risk of excessive scar tissue formation
- Safe to use from day one post-injury, when many other treatments cannot be applied
Is Laser Therapy Safe?
LLLT is safe for athletes at all levels of competition and is approved for clinical use without restrictions on athletic performance. The only consistent precaution is protective eyewear for both patient and therapist. It should not be used over suspected fracture sites before imaging, over active malignancy, or over the thyroid gland. Dr. Vaishali Suri screens all patients before commencing laser therapy and adjusts protocols based on injury type and healing stage.
Frequently Asked Questions
Does laser therapy hurt?
Laser therapy is painless. Athletes in acute pain are sometimes apprehensive about any treatment touching the injured area, but LLLT can be applied with no pressure — the handpiece is held lightly against or above the skin. There is no heat, vibration, or discomfort during treatment.
How many sessions of laser therapy will I need?
Acute sports injuries typically need six to eight sessions delivered intensively (daily or every other day) in the first two weeks. Subacute and chronic sports injuries may require eight to twelve sessions. Dr. Vaishali Suri integrates LLLT into the overall rehabilitation timeline to maximise tissue quality at each stage.
