Patients will be given written and oral consent by explaining the purpose of the study. Patients with fistula and non-grafted arms will be asked to fill out data collection forms at the first interview. Patients will then be asked to squeeze the stress ball 15 minutes before the start of hemodialysis treatment and for 15 minutes during hemodialysis treatment. This treatment will be performed during (nine) hemodialysis treatments. After the last session, data collection forms will be filled out again.

Use of stress Ball

1) place a stress ball in one hand (which hand will be left to the patients' wishes.) 2.squeeze the ball in your hand for 2-3 seconds after receiving it and then loosen it.

3.perform this application for a total of 30 minutes before and during hemodialysis treatment.

No intervention will be given to the control group other than standard treatment. Data collection forms will be completed before the first dialysis session and after the eighth session.

Before the first dialysis session and after the ninth session, the individual Introduction form, the Visual Analog scale (VAS) for stress level, the Beck anxiety scale and the hemodialysis comfort scale will be filled out.

The use of the stress ball by the experimental group patients will be reminded by a hemodialysis nurse who was not involved in the study.

Developed by Beck et al. (1988). The Cronbach alpha coefficient of the original scale is .93. The Turkish version of the Beck anxiety scale was prepared by Ulusoy et al. (1998). The scale consists of 21 items and two sub-dimensions.

BAO provides quadruple lycert-type measurement. The lowest possible score on the scale is 0 and the highest score is 63. Those who answered "never" to the scale questions received 0 points, those who answered "it did not affect much at a light level" received 1 points, those who answered "it was not pleasant, but I was able to endure" received 2 points, and those who answered "on a serious level, I was very hard to endure" received 3 points. The total score on the scale indicates

The General comfort scale developed by Kolcaba and the comfort scales developed specific to certain situations after it is a scale of the five likert type, which was validated and trusted by Şahin-Orak and his colleagues in 2017, consists of 9 items and 2 sub-dimensions. At least 3.00 and at most 15.00 points can be taken from the relaxation sub-dimension; at least 7.00 and at most 30.00 points can be taken from the overcoming sub-dimension. The lowest score from HDKO is 9, the highest score is 45. As the score gets closer to 45, the comfort level incre
