The protocol phases start one day before the patient's surgery and end on the first day of mobilization after surgery. The investigator explains the protocol steps to the patient before surgery and the patient is mobilized within the first 24 hours after surgery. Perform the protocol 4 times a day and more as tolerated. Mobilization protocol: Level 1: Patient is informed about mobilization and readiness is reinforced. Level 2: Passive and active ROM movements in bed should be performed at least 3 times a day. Level 3: Head of bed >60 degrees when the patient is sitting in bed. Duration target: 10-15 minutes. Level 4: Patient is seated on the edge of the bed. Duration target: 10-15 minutes. Level 5: The patient is helped to stand up. Level 6: First mobilization is achieved by allowing the patient to take 10-15 steps. The patient can mobilize at least 4 times a day.

No intervention was made to the control group, only data were collected at the same time as the study group.The patients in the control group was mobilized by the researchers according to the routine clinical mobilization practice.

The "Trait Anxiety Inventory (STAI FORM TX-2, SDS)" allows the individual to express how he or she generally feels. the emotions and behaviors expressed in the scale items are according to their degrees; It is marked as (1) Almost Never, (2) Sometimes, (3) Often, and (4) Almost Always. 0-19 points from the scale mean no anxiety, 20-39 points mean mild, 40-59 points mean moderate, 60-79 points mean severe anxiety, and individuals with a score of 60 and above need professional help.

The Tampa Kinesiophobia Scale (TKS) was used to evaluate the patients' fear of moving. The scale consists of 17 items and has a Likert type feature. Scale items are used in the form of 4-point Likert scoring (1=Strongly disagree, 2=Disagree, 3=Agree, 4=Completely agree) and the total score ranges from 17-68. A high score from the scale indicates a high fear of movement. It is recommended to use the total score obtained from the scale in studies. It was stated that the test-retest reliability was 0.81.

The State-Anxiety scale consists of twenty statements that evaluate how respondents' feel about anxiety "right now, at this moment" through four scales: one (not at all), two (somewhat), three (moderately so), and four (very much so). A rating of four indicates the presence of a high level anxiety and one indicates the absence of a high level anxiety. The anxiety level was found by calculation of scores, The range of scores is from 20-80, the higher the score indicating greater anxiety.

Patients' symptoms related to the first mobilization (pain, dizziness, nausea, blackout, anxiety, stress, fear of damaging the surgery site, fear of falling, inability to walk/movement, walking distance on the first day, walking distance at the end of the first day, total walking at the end of the first day) distance, total mobilization per day, orthostatic intolerance, orthostatic hypotension) will be scored using a Numerical Comparison Scale from 0-10. This form will be used before and after mobilization on the day of the first mobilization of the patients.
