How does Class IV laser therapy assist in pain modulation?

Class IV laser therapy plays a significant role in pain modulation primarily by increasing the release of endorphins and decreasing nociceptive signals. This process enhances the body's natural ability to manage pain and promote healing.

When Class IV lasers are applied to tissues, they stimulate photobiomodulation, which can trigger various biological responses. One of the key outcomes of this stimulation is the increased production and release of endorphins. Endorphins are neurotransmitters that act as natural pain relievers, helping to diminish the perception of pain experienced by the patient.

Additionally, Class IV laser therapy helps to reduce nociceptive signals, which are messages sent from injured tissues to the brain indicating pain. By modulating these signals, the therapy aids in alleviating discomfort and enhances overall pain management.

The other options do not accurately describe how Class IV laser therapy assists in pain modulation. Decreasing blood flow could potentially have a negative impact on recovery and healing. Improving skin texture is more related to cosmetic benefits rather than pain modulation. Focusing solely on muscle tissue overlooks the broader applications of Class IV laser therapy, which can benefit a wide range of tissues and conditions.
