This study aimed to determine the effects of holding the patient's hand and using a stress ball during the Intrauterine Insemination procedure on pain, anxiety, comfort, and physiological parameters. This study will be conducted as a randomized controlled trial with a pre-test-post-test procedure in the IVF Unit of a Medical Faculty Hospital in Turkey. The study sample was planned to include 120 participants, 40 women each in the stress ball, hand-holding, and control groups. Data will be collected using the Personal Information Form, Visual Analog Scale, State Anxiety Inventory, and General Comfort Scale Short Form. In the Stress Ball Group, participants are given a colored silicone stress ball (5-7 cm diameter) 5 minutes before the procedure. During the procedure, they are instructed to squeeze the ball twice after counting to 10 and repeat this until the procedure is complete. In the Hand-Holding Group, the researcher holds one of the participant's hands during catheter insertion and removal. The researcher's fingers are closed but not interlocked and placed gently on the participant's hand without additional movements or gloves. In the Control Group, Participants receive no additional intervention beyond the standard routine procedures.

Infertility is a significant social and health issue, negatively affecting couples, particularly women's biological, physical, and psychosocial well-being. Assisted reproductive techniques are utilized to help couples with infertility achieve parenthood (Taşkın, 2023). Among these techniques, the Intrauterine Insemination (IUI) procedure can lead to pain, anxiety, discomfort, and trauma, both from the procedure itself and from the emotional impact of infertility. Pain associated with trauma and anxiety may trigger adverse effects, such as increased catecholamine levels, reduced heart rate, blood pressure, and lung vital capacity, due to the activation of the sympathetic nervous system (Yıldız Fındık and Soydaş Yeşilyurt, 2017; Vaajoki et al., 2012).

To alleviate acute pain and enhance comfort during IUI procedures, in addition to medical interventions, non-pharmacological methods with minimal side effects are also critical (Stewart and Cox-Davenport, 2015). One such approach is the attention distribution method, which enables brain receptors to shift focus away from painful stimuli, thereby reducing pain perception and improving control (Elmali and Balcı Akpinar, 2017). The use of stress balls as a non-pharmacological method of attention distribution is particularly noteworthy. Stress balls are accessible, cost-effective, and safe. Furthermore, their use offers a holistic approach, incorporating touch, healing, and therapeutic effects (Yanes et al., 2018). A review of the literature reveals various findings on the psychometric and vital sign changes-such as anxiety, stress, comfort, and compliance-associated with stress ball use during medical procedures, including colonoscopy, endoscopy, extracorporeal shock wave lithotripsy (ESWL), prostate biopsy, radiography, hemodialysis, intravenous (IV) procedures, and polymerase chain reaction (PCR) testing (Apaydin Cirik et al., 2023; Çakır and Evirgen, 2023; Özen et al., 2023; Karataş and Gezginci, 2023, 2022; Gezginci et al., 2018a; Karataş and Gezginci, 2018; Quan et al., 2016). Additionally, some studies highlight the therapeutic or healing benefits of touch in children and intensive care settings (Garrett and Riou, 2021). However, the specific effects of hand-holding and stress ball use on pain, anxiety, comfort, and physiological parameters during the IUI procedure have not yet been thoroughly investigated.
