The Effect of Progressive Relaxation Exercises on Sleep Quality

The data of this study will be collected between May 2022 and December 2022. The research will be carried out with a total of 60 (experimental group=30, control group=30) patients treated for heart failure, myocardial infarction and angina pectoris in the cardiology clinic of a university hospital.

The study was planned as a randomized controlled experiment. Patients meeting the research criteria will be randomly assigned to 30 experimental-30 control groups by randomization method.

Information Form, Richard's Campbell Sleep Scale and commercial ELISA kit will be used as data collection tools in the research.

• Progressive Relaxation Exercises (Behavioral): In the first part of this audio material, which consists of three parts; The definition of deep relaxation, its purpose and points to be considered during exercise are included. The second part, consisting of an average of thirty minutes, includes the explanation of relaxation exercises with verbal commands accompanied by the sound of the stream. In the last part, there is only relaxation music without any commands.

Primary outcomes

• sleep quality, [06.00 am the day before the progressive relaxation exercise]: Richard's Campbell Sleep Scale (RCS) consists of 6 items. In the scale, patients are asked to evaluate between 0 and 100 points for each item. The 6th item, which evaluates the noise level in the environment, is not included in the total score evaluation. The result is obtained by dividing the total score obtained from the scale by the number of questions, and "0-25" points indicate "very bad sleep" and "76-100" points indicate "very good sleep".
• melatonin and serotonin in urine [06.00 am the day before the progressive relaxation exercise]: In order to determine the levels of serotonin metabolite 5-hydroxyindolacetic acid (5-HIAA) and melatonin metabolite 6-sulphatoxymelatonin from patients in the experimental and control groups, urine samples will be taken between 23:00 at night and 07:00 in the morning at the end of the first and fourth day. On the 5th day, after the last urine taken in the morning is added, a urine sample will be taken into a sample container containing 10-15 ml of 6 M HCl and stored at -80 degrees for analysis in the biochemistry laboratory.

Secondary outcomes

• sleep quality, [06.00 am, after 3 consecutive days of progressive relaxation exercise]: Richard's Campbell Sleep Scale (RCS) consists of 6 items. In the scale, patients are asked to evaluate between 0 and 100 points for each item. The 6th item, which evaluates the noise level in the environment, is not included in the total score evaluation. The result is obtained by dividing the total score obtained from the scale by the number of questions, and "0-25" points indicate "very bad sleep" and "76-100" points indicate "very good sleep".
• melatonin and serotonin in urine [06.00 am the day after the progressive relaxation exercise]: In order to determine the levels of serotonin metabolite 5-hydroxyindolacetic acid (5-HIAA) and melatonin metabolite 6-sulphatoxymelatonin from patients in the experimental and control groups, urine samples will be taken between 23:00 at night and 07:00 in the morning at the end of the first and fourth day. On the 5th day, after the last urine taken in the morning is added, a urine sample will be taken into a sample container containing 10-15 ml of 6 M HCl and stored at -80 degrees for analysis in the biochemistry laboratory.
