Design outcomes

Primary

Measure	Time frame
Visual analogue scale (VAS). Timepoint: Before starting the intervention and in every 10 laser therapy sessions. Method of measurement: In this way, Scale = 0 is considered for lack of sensitivity and Scale = 10 is considered as normal sensitivity and the patient is asked to choose a number between 0 and 10.;Two-point discrimination test. Timepoint: Before starting the intervention and in every 10 laser therapy sessions. Method of measurement: Static two-point discrimination test is performed by two objects on the skin, which can be used to measure the distance between two points. These objects should be blunt and non-sharp and have the ability to stimulate pain receptors. The closest distance that the patient can distinguish two points from one point is recorded.	—
