About this study
Official title: Trapezius Muscle Activity During Wall-Slide Exercise: Natural Vs Corrected Head Posture
The goal of this observational study is to investigate the effect of head posture on trapezius muscle activity and ratios during wall slide exercise. The main question the study aims to answer is:
•How does the trapezius muscle activity change during wall slide exercise when performed with a natural head posture and the corrected head posture? The participants performed wall slide exercise with their natural head posture and the corrected posture. For both interventions, muscle activity of the lower, middle and upper trapezius was measured with surface electromyography(EMG) Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the exercise.
Read the detailed description
Healthy individuals between the ages of 18 and 35 who have not had any pain in the upper extremity for the last 6 weeks, have musculoskeletal system pathologies of the upper extremity and/or any surgery were included in the study. Individuals who have had pain in the shoulder area for the last 6 weeks, had shoulder injury and/or shoulder surgery, have neurological, rheumatological or systemic diseases and body mass index (BMI) greater than 30 kg/m2 were excluded. Participants were asked to perform wall-slide exercise with both natural head posture and corrected head posture, separately. During the wall-slide exercise, muscle activations of upper trapezius (UT), middle trapezius (MT) and lower trapezius (LT) were measured with surface EMG Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the exercise.

Surface Electromyography Noraxon MiniDTS systemDevice
Trapezius muscle activities of 19 healthy individuals were measured with surface EMG Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the wall slide exercise under different head posture conditions: natural head posture and corrected head posture.

Clinical summary

The goal of this observational study is to investigate the effect of head posture on trapezius muscle activity and ratios during wall slide exercise. The main question the study aims to answer is:
•How does the trapezius muscle activity change during wall slide exercise when performed with a natural head posture and the corrected head posture? The participants performed wall slide exercise with their natural head posture and the corrected posture. For both interventions, muscle activity of the lower, middle and upper trapezius was measured with surface electromyography(EMG) Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the exercise.
Detailed description
Healthy individuals between the ages of 18 and 35 who have not had any pain in the upper extremity for the last 6 weeks, have musculoskeletal system pathologies of the upper extremity and/or any surgery were included in the study. Individuals who have had pain in the shoulder area for the last 6 weeks, had shoulder injury and/or shoulder surgery, have neurological, rheumatological or systemic diseases and body mass index (BMI) greater than 30 kg/m2 were excluded.

Questions about this trial
What is this clinical trial studying?
An observational study of Trapezius Muscle Atrophy, run by Ankara Yildirim Beyazıt University at 1 site in Turkey (Türkiye).
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 3 inclusion and 4 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 12 Mar 2025. 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 Turkey (Türkiye). 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?
Trapezius muscle activity (time frame: Baseline). 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 NCT06872957, which also lists 6 linked publications.
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 12 Mar 2025.
