The sentence; “Pain was evaluated by visual analog scale (VAS) and Likert scale.” In the Abstract should be replaced by; “Pain was evaluated by visual analog scale (VAS).”

The second sentence; “Patients were treated for 4 min at each point, producing energy of approximately 40 J/cm2 using a 850 nm gallium-aluminum-arsenide laser” in the Materials and methods is incomplete. The correct sentence is; “Patients were treated for 4 min at each side, producing total energy of approximately 40 J (43.2 J) for both sides of the paraspinal tissues using a 850 nm gallium-aluminum-arsenide laser.”
