Physical Workload Identify in Chest Compression Position Using Surface Electromyogram
A study testing chest compression with kneeling position and chest compression with standing position in people with Cardiopulmonary Resuscitation and Cardiac Arrest, run by Hanyang University at 1 site in South Korea.
Trial summary
The chest compression depth decreases over time after starting continuous chest compression due to the rescuers' fatigue. The investigators hypothesized that the frequency parameters from surface electromyogram from each muscle during chest compression may reflect the muscle fatigue of the rescuers.

About this study
The chest compression depth decreases over time after starting continuous chest compression due to the rescuers' fatigue.
The investigators hypothesized that the frequency parameters from surface electromyogram from each muscle during chest compression may reflect the muscle fatigue of the rescuers.
Then investigators can identify which of the body are mainly used and get tired by continuous chest compression using surface electromyogram.
- Conditions
- Cardiopulmonary Resuscitation, Cardiac Arrest
- Being tested
- chest compression with kneeling position, chest compression with standing position

What is being measured
The primary outcome is the main question the study is designed to answer.
median frequency of electromyogram
median frequency of electromyogram in 16 muscles during chest compression
The muscles are flexor carpi radialis, extensor carpi radialis, biceps brachii, triceps brachii, deltoideus, erector spinae (cervical area), trapezius, rhomboid, erector spinae (thoracic area), erector spinae (lumbar), obliquus externus abdominis, rectus abdominis, pectoralis, quadriceps femoris, biceps femoris, gastrocnemius. On the dominant side of the rescuers, we will attach sixteen electrodes on these muscles.
Measured: two weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The chest compression depth decreases over time after starting continuous chest compression due to the rescuers' fatigue.
The investigators hypothesized that the frequency parameters from surface electromyogram from each muscle during chest compression may reflect the muscle fatigue of the rescuers.
Then investigators can identify which of the body are mainly used and get tired by continuous chest compression using surface electromyogram.

Questions about this trial
What is this clinical trial studying?
A study testing chest compression with kneeling position and chest compression with standing position in people with Cardiopulmonary Resuscitation and Cardiac Arrest, run by Hanyang University at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
median frequency of electromyogram (time frame: two weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02088879, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2014.
