About this study
Official title: Effects of ShoulderSphere Exercises on Shoulder Stabilization, Strength, Proprioception, and Endurance in Young Adults
This study evaluated the effects of ShoulderSphere exercises on shoulder stability, muscle strength, proprioception, endurance, and functional performance in young adults.
ShoulderSphere is an exercise device that provides dynamic and multi-directional resistance during shoulder movements. The study compared an 8-week ShoulderSphere-based exercise program with a conventional shoulder stabilization exercise program based on selected Thrower's Ten exercises.

Young adults without current shoulder symptoms were included in the study. Participants were assigned to one of two exercise groups. Shoulder stability, functional upper-extremity performance, shoulder proprioception, and isokinetic muscle strength and endurance were assessed before and after the 8-week intervention.
The aim of the study was to determine whether ShoulderSphere exercises produced different effects compared with conventional shoulder stabilization exercises in young adults.
Read the detailed description
This study was designed as a controlled pretest-posttest intervention study in young adults. The purpose was to compare the effects of an 8-week ShoulderSphere-based exercise program with a conventional shoulder stabilization exercise program based on selected Thrower's Ten exercises.
Participants were young adults between 18 and 40 years of age who did not have current shoulder pain or clinical shoulder symptoms. Participants were assigned to either the ShoulderSphere exercise group or the conventional exercise group.
The ShoulderSphere group performed exercises using the ShoulderSphere device, which provides dynamic resistance and requires continuous control of shoulder movement. The conventional exercise group performed selected shoulder stabilization exercises based on the Thrower's Ten program. Both interventions were applied for 8 weeks.
Outcome assessments were performed before and after the intervention period. Shoulder stability was assessed using the Closed Kinetic Chain Upper Extremity Stability Test. Functional upper-extremity performance was assessed using the seated single-arm medicine ball throw test. Shoulder proprioception was assessed using an active joint position sense test. Isokinetic shoulder muscle strength and endurance were assessed using an isokinetic dynamometer.
The main purpose of the study was to examine whether ShoulderSphere exercises had different effects from conventional shoulder stabilization exercises on shoulder stability, strength, proprioception, endurance, and functional performance in young adults.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ShoulderSphere-Based Exercise ProgramBehavioural
Participants performed an 8-week shoulder exercise program using the ShoulderSphere device. The program aimed to improve shoulder stability, proprioception, muscle strength, endurance, and functional upper-extremity performance through dynamic and multi-directional shoulder control exercises.
Conventional Shoulder Stabilization Exercise ProgramBehavioural
Also called Thrower's Ten-Based Exercises
Participants performed an 8-week conventional shoulder stabilization exercise program based on selected Thrower's Ten exercises. The program aimed to improve shoulder stability, proprioception, muscle strength, endurance, and functional upper-extremity performance.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in shoulder stability from baseline to 8 weeks
Shoulder stability was assessed using the Closed Kinetic Chain Upper Extremity Stability Test. The number of touches completed during the test was recorded before and after the 8-week intervention period.
Measured: Baseline and 8 weeks
Secondary outcomes (4)
Change in functional upper-extremity performance from baseline to 8 weeks
Functional upper-extremity performance was assessed using the seated single-arm medicine ball throw test. The throwing distance was recorded before and after the 8-week intervention period.
Measured: Baseline and 8 weeks
Change in shoulder proprioception from baseline to 8 weeks
Shoulder proprioception was assessed using an active joint position sense test for internal and external rotation. Absolute error values were recorded before and after the 8-week intervention period.
Measured: Baseline and 8 weeks
Change in isokinetic shoulder muscle strength from baseline to 8 weeks
Isokinetic shoulder muscle strength was assessed using an isokinetic dynamometer during internal and external rotation. Measurements were performed before and after the 8-week intervention period.
Measured: Baseline and 8 weeks
Change in isokinetic shoulder muscle endurance from baseline to 8 weeks
Isokinetic shoulder muscle endurance was assessed using an isokinetic dynamometer during repeated shoulder internal and external rotation movements. Measurements were performed before and after the 8-week intervention period.
Measured: Baseline and 8 weeks

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?
Change in shoulder stability from baseline to 8 weeks (time frame: Baseline and 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 11 Jun 2026.
