Examining the Effectiveness of Multiwave Locked System Laser Treatment in Chronic Low Back Pain

Numerical Pain Rating Scale: Ratings from 0 to 10 range from no pain to the highest pain level imaginable. Studies show that a 2-point change in the evaluation made with this scale indicates a clinically significant change beyond the limits of measurement error.Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'.

The Roland-Morris Disability Questionnaire: This survey contains 24 questions about the impact of low back pain on a person's functionality. The yes answer given by the people is evaluated as 1 point, the no answer is evaluated as 0 points, and a total score between 0 and 24 is received.The score ranges from 0 (no disability) to 24 (max. disability) depending on the questionnaire used.

Esthesiometer: Measurements will be taken by moving horizontally from the midline where the spinous process of the 3rd lumbar vertebra is located to the dominant part of the person. The evaluation will start from the position where the distance between two points is 0 mm, and the distance will be increased until the person can distinguish between two points. Around this determined threshold, 5 increasing and decreasing evaluations will be made and the average of the evaluation will be taken.

MicroFET 2: Measurements will be taken 5 centimeters to the right and left of the spinous processes of the 3rd and 5th Lumbal vertebrae, which will be marked before. Two more points (on the tibialis anterior muscle of the right and left legs, 5 centimeters lateral to the tuberosity tibia) will be marked and used for control. The probe will be applied perpendicular to the skin, and the pressure will be gradually increased, starting from the point where no pressure is applied at first. At the point when the feeling of pressure turns into pain, participants will be instructed to call this point. This value will be recorded during the application, and after waiting the required time, additional measurements will be taken to calculate the pressure pain threshold.

SF 12: The SF-12 health survey is a self-reported outcome measure designed for use among the general population. It is a 12-item short-form health survey that assesses the same eight health domains as the SF-36 Health Survey. Each health domain score contributes to the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Scores above 50 indicate a better-than-average health-related quality of life, while scores below 50 suggest below-average health.

Pittsburgh Sleep Quality Index: 19 out of 24 questions are self-answered questions. While other questions include questions to get information from a roommate or bed partner, some questions in the index are included in the scoring. There are 7 components and the total score varies between 0 and 21. If the total PSQI score is below 5, sleep quality is considered good, and if it is above 5, sleep quality is considered poor.

Numerical Rating Scale: Participants will score their satisfaction between 0 and 10, with higher scores indicating a higher level of satisfaction.
