The Effect of Therapeutic Touch on Sleep, Comfort, and Physiological Parameters in Intensive Care Patients: A Randomized, Placebo-Controlled Study

Intensive care units are critical clinical areas where patients in life-threatening conditions receive care under advanced technology and continuous monitoring. In this environment, patients' sleep patterns and comfort levels are frequently disrupted, which can negatively affect physiological stability and the recovery process. The aim of this thesis proposal is to examine the effects of therapeutic touch applied to intensive care patients on sleep quality, comfort level, and physiological parameters. The research is planned as a randomized experimental study with intervention, placebo, and control groups. The study will be conducted in the Coronary Intensive Care Unit of Fırat University Hospital between April 2026 and January 2027, and a total of 90 patients meeting the research criteria will be randomized into intervention (n=30), placebo (n=30), and control (n=30) groups. The research materials consist of the Patient Identification Form, VAS-Comfort Scale, Sleep Scale, and measurements of physiological parameters (heart rate, blood pressure, body temperature, respiratory rate, oxygen saturation). The intervention group will receive therapeutic touch, the placebo group will receive superficial contact, and the control group will receive routine care. The applications will be performed daily at 8:00 PM, and comfort scale and physiological parameters will be measured before and 30 minutes after the application. Sleep quality, as an outcome variable occurring throughout the night, will be assessed the following day using the Sleep Scale. This process will be repeated for 3 days. The obtained data will be analyzed using appropriate statistical methods. In addition to descriptive statistics, One-Way Analysis of Variance (ANOVA) will be used for intergroup comparisons, and Repeated Measures ANOVA will be used to evaluate changes over time. In case of a significant difference, Bonferroni corrected post-hoc tests will be applied. If parametric assumptions are not met, appropriate non-parametric tests will be preferred. The significance level will be accepted as p<0.05. This study aims to contribute to the development of evidence-based practices in nursing care by revealing the effects of therapeutic touch on sleep quality, comfort level, and physiological parameters of intensive care patients.
