Which class includes laser therapy and other light-based treatments?

• A. Cryotherapy
• B. Light therapy
• C. Electrotherapy
• D. Hydrotherapy

Answer: (B)

Light therapy uses specific wavelengths of light to influence tissue healing and pain, and laser therapy is a form of this approach. Other light-based modalities, such as LED or infrared therapies, are grouped together under the same class because they rely on light energy rather than cold, electricity, or water. This distinguishes them from cryotherapy, which involves cold application; electrotherapy, which uses electrical currents; and hydrotherapy, which uses water-based techniques. So the class that includes laser therapy and other light-based treatments is light therapy.
