When patients are admitted to the Orthopedics and Traumatology Clinic for arthroplasty and agree to participate in the study, they will be informed about the research process and written informed consent will be obtained. The Descriptive Information Form, Numeric Rating Scale (NRS), The Fear of Falling Scale, and the State-Trait Anxiety Inventory (STAI) will be administered through face-to-face interviews by the researcher. After the pre-tests are completed, patients will be randomly assigned to the intervention and control groups.
In the preoperative period, upon admission to the clinic, patients in the intervention group will receive progressive muscle relaxation exercises (PMRE). To enhance concentration and minimize the impact of ambient noise, patients will listen to the exercises using headphones.
On the first postoperative day, the patient will be revisited by the researcher. After the physician explains that the patient will be mobilized, the State-Trait Anxiety Inventory will be administered, and the patient's pain and fear of falling will be evaluated. PMRE will then be performed, followed by the patient's first mobilization. One hour after mobilization, fear of falling, state-trait anxiety, and pain will be reassessed. The PMRE sessions, lasting approximately 30 minutes, will be guided with slow and rhythmic instructions, delivered in a soft tone of voice and accompanied by music.
For patients in the control group, the administration of the questionnaires will be conducted in the same manner as in the intervention group. Upon admission to the clinic, the Descriptive Information Form, Numeric Rating Scale (NRS), The Fear of Falling Scale, and the State-Trait Anxiety Inventory will be completed through face-to-face interviews. On the first postoperative day, the patient will be revisited by the researcher, and after the physician explains that the patient will be mobilized, the State-Trait Anxiety Inventory will be administered again, and the patient's pain and fear of falling will be evaluated. The patient's first mobilization will then be carried out. One hour after mobilization, fear of falling, state-trait anxiety, and pain will be reassessed.
Pain assessment will begin from the second postoperative hour. Pain intensity will be evaluated every 2 hours for the first 8 hours and then every 4 hours thereafter. After the final assessments of the control group are completed, PMRE will be administered by the researcher.
