Impact of Stress Balls on Cannulation Pain in Hemodialysis: A Randomized Study

The intervention in this study involves the use of stress balls provided to participants in the intervention group. These are specially designed medium-firm silicone balls intended for squeezing with the hand opposite the one receiving cannulation during hemodialysis sessions. The primary objective of this intervention is to offer a simple, non-pharmacological method to potentially alleviate the pain associated with the cannulation process. Participants are instructed to use the stress ball for a period of three minutes before the start of cannulation. This activity is hypothesized to focus the participant's attention and possibly reduce the perception of pain, contributing to a more comfortable and less distressing cannulation experience.
