Objectives:
The trial aimed to compare the pain perceived by women during intrauterine device (IUD) insertion, with or without virtual reality (VR) therapy. Furthermore, anxiety during the insertions, pain after the insertions, and satisfaction with the insertions were compared.
Methods:
The trial was designed as a prospective, bi-centric, randomized, open-label interventional trial. All adult women that chose an IUD during a contraceptive consultation, and who provided informed consent were eligible. Women under legal guardianship, not affiliated to a national social security system, and with pre-existing dizziness, severe facial wounds, or epilepsy were not eligible. Eligible women were randomly allocated either standard care without VR therapy (Control group) or with VR therapy (Experimental group). Pain, anxiety, and satisfaction were measured using a 10-cm numerical scale.
Results:
Between September 2020 and April 2022, 100 women were randomized: 50 to each group. The mean pain scores during IUD insertion were 5.4 cm in the Control group versus 5.1 cm in the Experimental group (p = 0.54). Mean anxiety during insertion were 4.8 cm in the Control group versus 4.2 cm in the Experimental group (p = 0.13). While mean pain perceived after insertions were 2.4 cm in the Control Group and 2.4 cm in the Experimental group (p = 0.98). Mean satisfaction with the insertions was 9.6 cm in both groups (p = 0.87). Anxiety before IUD insertion, as well as anticipated pain, were significantly correlated with pain perceived during insertions.
Conclusions:
VR therapy performed during the procedure did not alleviate perceived pain in women undergoing IUD insertions.
