The researcher, a second-degree Reiki therapist, performed the Reiki therapy. Patients were told to lie comfortably on their backs after they were informed about the therapy. Each of the 7 Reiki hand positions was applied sequentially. Each of the hand positions took 2-3 minutes, requiring 30-40 minutes in total.

Routine maintenance will be applied

Reiki is applied touching the energy centers of the body (chakras). There are seven main and many small chakras on a body. Chakras are located on the front and back sides of the body in a vertical line that runs along the middle of the body in humans. A complete Reiki therapy includes all the chakras and organs.

It is a 22-item scale that measures four subscales: behavior (6 items), affect (5 items), sensory (5 items), and cognition/mood (6 items). Each item has 11 response categories on a 0-10 metric with verbal descriptors anchoring the endpoints. Each subscale is scored individually and then aggregated together for an overall score, with higher scores reflecting more fatigue.

The PSQI is a valid and consistent survey comprising of 19 questions to assess quality and amount of sleep and the existence of a sleep disorder and its level in the previous month. The scale was adapted into the Turkish language by Agargün et al. (1996). The scale consists of seven components that assess patients subjective sleep quality, sleep delay, use of sleeping medication and disfunction in daily activities. Each item scores in the range 0-3 points and the total score of the seven components gives the total PSQI score. The total score has a value between 0-21 and a high total score demonstrates a poor quality of sleep. A total PSQI score which is ≤5 indicates "good sleep", and a score which is >5 indicates "poor sleep"
