Laser therapy: scientific basis and clinical role

Area of Science:

• Biomedical optics
• Photomedicine
• Cellular biophysics

Background:

• Laser irradiation can destroy tissue at high intensities.
• Low-intensity laser radiation can alter cellular function without significant heating.
• This phenomenon forms the basis for conservative treatment of musculoskeletal, neurological, and soft tissue conditions globally.

Purpose of the Study:

• To review the 25-year history and scientific basis of laser therapy.
• To discuss clinical applications and reasons for limited US acceptance.
• To provide an overview of current research and its impact on future US clinical practice.

Main Methods:

• Literature review of studies on laser therapy.
• Analysis of historical data and scientific evidence.
• Examination of clinical case studies and research findings.

Main Results:

• Laser therapy has a 25-year history with a defined scientific basis.
• It is used globally for various conditions, but acceptance in the US is limited.
• Current research indicates a growing role for laser therapy in US clinical practice.

Conclusions:

• Low-intensity laser therapy offers a non-destructive method for cellular function alteration.
• Understanding its history, applications, and scientific basis is crucial.
• Ongoing research is expected to increase the adoption of laser therapy in the US.
