In our study, Visual Analog Scale(VAS) will be used to measure subjectively perceived pain. The Visual Analogue Scale (VAS) is a horizontal line of 0-10 cm denoting the absence of pain at one end and the most severe pain possible at the other. The subjects will be asked to mark the pain they have experienced in the last 3 days on the VAS.
Pain Disability Questionnaire (PDQ) will be used to measure pain-related disability. The Pain Disability Questionnaire (PDQ) is a seven-item scale aiming to determine the functional losses related to the musculoskeletal system suffered by the patient due to pain. From the patient, by giving 0 to 10 points to all questions; are asked to rate the impact on daily living activities, including family-home responsibilities, leisure activities, occupation, social activities, sexuality, and self-care. The total score ranges from 0 to 70. If the result is over 40 points, it means high disability.
A Digital Pressure Algometer will be used to evaluate the pressure pain threshold. Pressure pain threshold is the amount of pressure at which pressure perception is first perceived as painful. It is applied until the participant states the point where the pressure is perceived as painful for the first time by saying 'stop'. The average of the two measurements is taken. The pressure pain threshold will be evaluated at the points in the pectoral muscle region, the lateral trunk side, and the upper trapezius muscle.
Semmes Weinstein Monofilaments will be used. The mechanical sensing threshold and the mechanical pain threshold will be measured. The mechanical sensing threshold is the point at which the stimulus is first felt. The mechanical pain threshold is the point at which the stimulus is first felt painful. It will be applied to the inner side of the upper arm, the lateral trunk side and the quadriceps muscle.
The Pain Catastrophizing Scale (PCS) will be used to measure pain-related catastrophication. This scale is a 14-item scale developed to examine catastrophic factors such as rumination, magnification, and weakness that are effective in the mechanism of pain. PCS scores range from 0 to 52 points. It is understood that the higher the score, the higher the catastrophization.
Psychological Symptoms will be measured using the Depression Anxiety-Stress Scale-21(DASS-21). This scale measures the level of depression, anxiety and stress. It consists of 21 items and seven items in each subscale.
Functional Assesment of Cancer Treatment (FACT-B+4) Scale Coster et al. to evaluate the effects of arm morbidity on quality of life after breast cancer surgery. It consists of 42 items and 6 subscales: physical well-being, social/family well-being, emotional well-being, functional well-being, breast cancer and arm.
