A non-invasive physical therapy method in which low-level laser light (LLLT) is applied to the skin without producing heat, supporting cellular-level pain control and tissue healing processes.
Indication
- Soft tissue inflammations such as tendinitis, bursitis, and epicondylitis
- Adjunctive treatment of chronic neck and low back pain
- Pain management associated with knee osteoarthritis
- Symptom control in entrapment neuropathies such as carpal tunnel syndrome
- Recovery period after musculoskeletal injuries
- Support for skin wound healing (in limited indications)
Preparation
- The skin in the treatment area should be clean and free of moisturizer
- Appropriate laser safety goggles must be worn during treatment
- Tattoos, permanent makeup, or pigment in the treatment area should be reported to the physiotherapist
- Use of photosensitizing medications (some antibiotics, retinoids) is reviewed
- Open wounds, bleeding, tumors, or pregnancy must be reported to the physician
How it's performed
- The patient is positioned for treatment, and both patient and operator wear protective goggles
- The laser device tip is placed in contact with the painful area or held at a short distance
- Wavelength, dose, and duration are adjusted by the physiotherapist according to the diagnosis
- The device is applied to one point for a few minutes, then moved to nearby points
- Total session time is generally 5-15 minutes
- The application is performed without producing a sensation of heat or stinging
Post-procedure
- Changes in pain intensity are evaluated after several sessions
- Generally 2-3 sessions per week are applied, totaling 8-15 sessions
- Benefit is enhanced when combined with an exercise program
- If response is inadequate, the diagnosis and treatment plan are reviewed
- Lifestyle and exercise habits are important for long-term durability
Risks
- LLLT is not sufficient on its own; it is applied together with exercise and other modalities
- It is not applied over tumor regions, open epiphyseal plates, or the abdomen during pregnancy
- Direct exposure to the eyes can cause serious eye injury; goggles are mandatory
- Photosensitizing medications can alter the effect; the physician must be informed
- The level of evidence varies by indication; benefit may be limited for some conditions
FAQ
Is laser therapy painful?
Low-level laser therapy (LLLT) does not produce noticeable heat on the skin and is usually not felt. Mild warmth or tingling may be perceived; this is normal.
Can it damage or burn the skin?
Therapeutic (low-level) laser applied with the correct parameters does not cause burns or skin damage. It is different from the cutting or local-heating lasers used in aesthetic procedures.
After how many sessions are results seen?
An average of 8-15 sessions is recommended; initial changes are usually noticed after 4-6 sessions. The response is individual and is influenced by adherence to exercise.
Is it applied during pregnancy?
It is not recommended over areas close to the uterus such as the abdomen and lower back during pregnancy. Even for distant areas, the decision is always made after physician evaluation.
