Routine Plaster intervention will be applied to the control group. No action will be taken.

During the plaster intervention process, the experimental group will squeeze the stress ball.

The child and parents will be taken to the procedure room for the casting procedure. The plastering process in children takes an average of 10-15 minutes. In the experimental group, the stress ball selected by the child will be started 1-2 minutes before the casting process and will be watched for an average of 10 minutes. If the procedure is prolonged, the time for squeezing and playing with the stress ball will be extended.

In this form, there are questions about the child's age, gender, weight, age of the mother and father, presence of long-term illness, previous hospitalization status and reason, previous surgery status, presence of medication on continuous use, analgesic intake in the last 6 hours.

The CFS, which was first used in 2003, is a scale with proven validity and reliability developed to assess the child's fear/anxiety and its level. The scale includes five different facial expressions, with no fear/anxiety at one end and very intense fear/anxiety at the other end, and is evaluated on a 0-4 point scale. 0: no fear/anxiety, 4: extreme fear and anxiety.

The CAS-D is shaped like a thermometer with a bulb at the bottom and horizontal lines with intervals going upwards. It is intended for children aged 4-10 years. The scale instructs children to "Imagine that all your anxious or angry feelings are at the bulb or bottom of the thermometer". Following the data collection, two members of the research team review and score the child's CAS-D scores. The score can range from 0 to 10.
