Impact of a Cueing Device on Upper Extremity Muscle Strength in Swimmers
A study testing External Cueing Device and Exercise in people with Healthy Volunteers Only, run by University of South Alabama at 1 site in United States.
Trial summary
The goal of this study is to find out if a tool called an external cueing device (ECD) can help young swimmers improve their shoulder function. An ECD is a tool that limits arm movement and gives the swimmer a target to focus on while doing exercises. Read more about this study

About this study
Official title: Impact of a Cueing Device on Upper Extremity Muscle Strength in Swimmers: A 6-Week Training Protocol Using Scapular Stabilization Exercises.
The goal of this study is to find out if a tool called an external cueing device (ECD) can help young swimmers improve their shoulder function. An ECD is a tool that limits arm movement and gives the swimmer a target to focus on while doing exercises. The main questions this study will answer are:
- Does using an ECD during certain exercises improve muscle strength?
- Does using an ECD while exercising help with shoulder stability?
Participants will:
- Test their shoulder muscle strength and stability at the beginning of the study.
- Complete 8 exercises as part of their regular dry-land training program for 6 weeks.
- Repeat the same tests after 3 weeks and again at the end of the study.
- Conditions
- Healthy Volunteers Only
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
External Cueing DeviceDevice

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in isometric muscle torque production at 180 degrees shoulder abduction
Handheld dynamometer assessment of force production times lever arm distance (Newton.meters) of prone shoulder elevation in 180 degrees of abduction completed at baseline, after 3 and 6 weeks of the training program.
Measured: Baseline, 3 weeks, 6 weeks.
Change from baseline in isometric muscle torque production at 135 degrees shoulder abduction
Handheld dynamometer assessment of force production times lever arm distance (Newton.meters) of prone shoulder elevation in 135 degrees of abduction completed at baseline, after 3 and 6 weeks of the training program.
Measured: Baseline, 3 weeks, 6 weeks.
Change from baseline in isometric muscle torque production at 90 degrees shoulder abduction
Handheld dynamometer assessment of force production times lever arm distance (Newton.meters) of prone shoulder elevation in 90 degrees of abduction completed at baseline, after 3 and 6 weeks of the training program.
Measured: Baseline, 3 weeks, 6 weeks.
Change from baseline in modified Athletic Shoulder Test at 180 degrees shoulder abduction
Maximum isometric force production with lying prone into a handheld dynamometer at a given lever arm distance results in muscle torque (Newton.meters) reading. This portion of the test is conducted at 180 degrees of abduction.
Measured: Baseline, 3 weeks, 6 weeks.
Change from baseline in modified Athletic Shoulder Test at 135 degrees shoulder abduction
Maximum isometric force production with lying prone into a handheld dynamometer at a given lever arm distance results in muscle torque (Newton.meters) reading. This portion of the test is conducted at 135 degrees of abduction.
Measured: Baseline, 3 weeks, 6 weeks.
Change from baseline in modified Athletic Shoulder Test at 90 degrees shoulder abduction
Maximum isometric force production with lying prone into a handheld dynamometer at a given lever arm distance results in muscle torque (Newton.meters) reading. This portion of the test is conducted at 90 degrees of abduction.
Measured: Baseline, 3 weeks, 6 weeks.
Closed Kinetic Chain Upper Extremity Stability Test Power Score
Two strips of tape are placed 36 inches apart. Participants assume a push up position (male) or pushup on knees (Female) and are instructed to reach across and touch the opposing hand alternating arms. Maximum number of touches in 15 seconds is recorded. Normalization is made by multiplying the raw touch score by 0.68 x Subject weight in Kg (representing the mass on the head arms and trunk) and dividing by the 15 seconds. Higher number indicates increased shoulder stability.
Measured: Baseline, 6 weeks.

Closed Kinetic Chain Upper Extremity Stability Test Raw Touch Score
Two strips of tape are placed 36 inches apart. Participants assume a push up position (male) or pushup on knees (Female) and are instructed to reach across and touch the opposing hand alternating arms. Maximum number of touches in 15 seconds is recorded. Higher number of touches indicates increased shoulder stability

Closed Kinetic Chain Upper Extremity Stability Test Touch Score
Two strips of tape are placed 36 inches apart. Participants assume a push up position (male) or pushup on knees (Female) and are instructed to reach across and touch the opposing hand alternating arms. Maximum number of touches in 15 seconds is recorded. Touches are adjusted for subject height by dividing raw touch by subject height (in inches based on prior literature). Higher number of touches indicates increased shoulder stability
Measured: Baseline, 6 weeks.

Distance from floor to wrist crease, measured in cm.
Measured: Baseline, 3 weeks, 6 weeks.

Questions about this trial
What is this clinical trial studying?
A study testing External Cueing Device and Exercise in people with Healthy Volunteers Only, run by University of South Alabama at 1 site in United States.
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 5 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 13 Apr 2026. 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 United States. 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?
Change from baseline in isometric muscle torque production at 180 degrees shoulder abduction (time frame: Baseline, 3 weeks, 6 weeks.). The study lists 7 primary outcomes in all. 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 NCT06923930, which also lists 2 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 13 Apr 2026.
