What is the primary reason for using laser therapy in treating arthritis?

Using laser therapy for treating arthritis primarily serves to relieve pain and reduce inflammation. This therapy employs specific wavelengths of light that interact with the body's tissues, promoting healing and alleviating symptoms associated with arthritis. The laser's energy penetrates the tissues, leading to increased blood circulation in the affected areas, which can help decrease swelling and stiffness that are commonly associated with arthritic conditions.

Pain relief is a crucial aspect of managing arthritis, as it significantly impacts a patient's quality of life. By targeting pain pathways and promoting cellular repair processes, laser therapy helps patients regain mobility and function, making it an effective treatment strategy in the management of arthritis.

The other options do not align with the therapeutic goals of laser therapy in this context. For instance, enhancing stiffness, increasing swelling, or immobilizing joints aren't desirable outcomes in arthritis treatment, where the focus is typically on pain relief, restoring function, and minimizing inflammation.
