A new type of very low-power modulated laser: soft-tissue changes induced in osteoarthritic patients revealed by sonography

Patients with symptomatic osteoarthritis of the cervical spine were studied by ultrasound examination. The region of interest was the soft connective tissue layer above the right and the left superior trapezium that revealed a significant difference in thickness between the left and right side. The aching side was treated with a new type of very low-power, modulated laser for 3 min. Immediately after application, the sonographic examination revealed a significant symmetrization of the subcutaneous tissue.
