Study summary

This randomized controlled trial evaluates the effect of acupressure application on nurses' sleep quality and daytime sleepiness providing care in surgical clinics. This study hypothesizes that acupressure improves sleep quality and reduces daytime sleepiness.

Read the detailed description

Methods: In the study, 60 nurses were randomly assigned to acupressure and placebo acupressure groups. To the acupressure group (n = 30), an average of 10 minutes will be applied to the Shen Men, the 7th acupoint (HT7) of the heart meridian located between the ulna and pisiform bones, on the radial side of the flexor carpi ulnaris tendon, and the Sanyinjia points on the splenic meridian (SP6) located on the inner side of the lower leg, four fingers above the ankle and behind the tibia. In the placebo acupressure group (n = 30), the points 1.5 cm away from the HT7 and SP6 points (four points in total) will be applied for an average of 10 minutes. The primary outcome of the research is the effect of acupressure on the sleep quality of nurses. The secondary outcome of the study is to determine the effect of acupressure on daytime sleepiness. The outcomes will be collected before and four weeks after the acupressure and placebo acupressure administration.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Acupressure Group

    The experimental group will be given acupressure on their own, three times a week for four weeks, one hour before going to bed at night.

    Other: Acupressure

  • Other
    Placebo Acupressure Group

    The control group will be given plasebo acupressure on their own, three times a week for four weeks, one hour before going to bed at night.

    Other: Plasebo acupressure

Interventions

  • OtherAcupressure

    The experimental group will start with HT7 points and continue with SP6 points. The application will be carried out by determining the priority order of the points with the draw. Attention will be paid to the intensity and duration of the pressure deemed appropriate. Since the individuals' responses will differ, the stiffness and pressure will be adjusted according to the individual's sensitivity not to cause tissue damage. Before starting the application, around the area to be pressed for 20-30 seconds will be gently rubbed with palm. With the gentle rubbing of the surrounding tissue, the tension and tissue sensitivity in warming, relaxing and preparatory will be reduced, and the tissue will be relieved. After, the point determined will be pressed manually for 2 minutes.

    Also known as: Acupress

  • OtherPlasebo acupressure

    In the control group, the application will start with the points 1.5 cm around the HT7 and SP6 points. The application process will continue in the same way with acupressure group and the pressure intensity will be less.

What researchers measure

Primary outcomes

  1. Sleep quality evaluated using the Pittsburgh Quality Sleep Index

    The total scale score is in the range of 0 (minimum) -21 (maximum), and the high total Pittsburgh Quality Sleep Index (PSQI) score indicates that sleep quality is low. A total PSQI score between 0-4 indicates good sleep quality, while between 5-21 shows that sleep quality is low.

    Time frame: Change from before implementation and 4th week of practice.

Secondary outcomes

  1. Daytime sleepiness evaluated using the Epworth Sleepiness Scale

    This scale, which is a four-point Likert type, aims to evaluate the probability of sleepiness during the individual's daily life between 0-3 points. The scale score is in the range of 0 (minimum) -24 (maximum), and a total Epworth Sleepiness Scale score of 11 or above indicates excessive daytime sleepiness.

    Time frame: Change from before implementation and 4th week of practice

Ran from Mar 2021 to primary completion in Apr 2021, 0 months.

Of 1,211 non-industry interventional studies with no phase under Sleep Initiation and Maintenance Disorders, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 35. This study's 0 months is below that.

Counting every sponsor, half of 1,289 studies reached it within 15 months; a quarter within 6 and three quarters within 34.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 8, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
