About this study
Official title: Effect of Reiki Applied After Coronary Angiography on Pain and Comfort Level: A Randomized Single-blind Placebo-controlled Study
Coronary angiography is an invasive imaging technique that directly visualizes the anatomical structure of the coronary arteries and is considered the gold standard for diagnosing significant coronary artery disease. In the post-coronary angiography period, alleviating pain and enhancing patient comfort are important goals of clinical care. Reiki is an energy-based complementary therapy aimed at supporting the body's natural healing processes and promoting relaxation. Among non-pharmacological interventions, Reiki-a practice rooted in Traditional Chinese Medicine and meaning universal life energy-is a safe, cost-effective, and easily applicable method. Studies have shown that Reiki is effective in reducing pain, anxiety, fear, and stress, as well as in improving comfort and holistic well-being. This study was designed to examine the effects of Reiki therapy administered after coronary angiography on patients' levels of pain and comfort.
Read the detailed description
This study is a randomized, single-blind, placebo-controlled trial designed to evaluate the effect of Reiki therapy on pain and comfort levels in patients undergoing coronary angiography. Participants are randomly assigned to one of three groups: Reiki intervention, sham Reiki, or control group.
The Reiki intervention is administered by a trained practitioner for approximately 21-30 minutes following the procedure, focusing on standard energy points. The sham Reiki group receives a similar procedure without therapeutic intent, while the control group receives standard care only.
Pain levels are assessed using the Visual Analog Scale (VAS), and comfort levels are measured using the General Comfort Scale Short Form. Measurements are conducted at baseline and at specified intervals following the intervention.
The study aims to provide evidence regarding the effectiveness of Reiki as a complementary, non-pharmacological intervention in post-procedural nursing care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ReikiBehavioural
Reiki therapy applied by trained practitioner for 30 minutes.
Sham reikiBehavioural
Sham Reiki applied by same practitioner, mimicking Reiki without actual energy technique.
| Study group | Role | What they receive |
|---|---|---|
| Reiki | Experimental | Participants receive a 30-minute Reiki session by a trained practitioner after coronary angiography. Pain and comfort are assessed at four time points. Receives: Behavioral: Reiki |
| Sham reiki | Placebo comparator | Participants receive a 30-minute sham Reiki session mimicking Reiki hand positions without actual energy intervention. Pain and comfort are assessed at the same time points. Receives: Behavioral: Sham reiki |
| Control | No intervention | Participants receive standard post-angiography care without any Reiki or sham intervention. Pain and comfort are assessed at the same time points. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain level
Pain intensity measured using Visual Analog Scale (VAS, 0-10) via face-to-face interviews at the specified time points.
Measured: Baseline (before intervention), 30 minutes after intervention, 2 hours after intervention, and prior to first mobilization (within 24 hours).
Secondary outcomes (1)
Comfort level
Comfort level was assessed using the "General Comfort Scale Short Form" through face-to-face interviews at the same locations.
Measured: Baseline (before intervention), 30 minutes after intervention, 2 hours after intervention, and prior to first mobilization (within 24 hours).
