The numerical pain scale was developed to assess the severity of pain. In this scale, the severity of the patient's pain is described with numerical values. Using numerical scales, pain severity is assessed by starting with "0" and grading up to "10". "0" indicates no pain, and "10" indicates unbearable pain. For the scale, the patient is asked to express the level of pain they feel at that moment with a number. The number expressed by the patient is accepted as the severity of the pain felt at that moment.

Fatigue Severity Scale (FSS): FSS is a scale consisting of nine items that evaluate the general effect of fatigue on daily activities. In the scale, individuals are asked to rate the fatigue they have felt throughout the past week from 1 to 7. Each section is scored between 1 (I completely disagree) and 7 (I completely agree). The total score is calculated by taking the average of the nine items. The cut-off value for pathological fatigue is determined as 4 and above. The lower the total score, the less fatigue there is.

Insomnia Severity Index: Developed to determine the degree of insomnia symptoms, this can be used in the clinical evaluation of insomnia. It is a five-point Likert-type scale consisting of seven items. Each item is scored between 0 and 4, and the total score varies between 0-28. A score between 0-7 on the scale indicates clinically insignificant insomnia, 8-14 indicates the lower threshold of insomnia, 15-21 indicates clinical insomnia (moderate severity), and 22-28 indicates clinical insomnia (severe).
