Influence of Anthropometric Data, Shoulder Complex Muscle Strength, and Abdominal-lumbar Endurance in Closed Kinetic Chain Upper Extremity Stability Test

Influence of Anthropometric Data, Shoulder Complex Muscle Strength, and Abdominal-lumbar Endurance in Closed Kinetic Chain Upper Extremity Stability Test

A previous study of the Closed Kinetic Chain Upper Extremity Stability Test (EPOLTEST) in a population aged 18 to 25 years isolated 3 main factors influencing the CKCUEST score: upper extremity span, weight, and sex of the individual. A predictive equation for the CKCUEST score was thus established and to date has a capacity to determine the real score of approximately 51%.

The results of this first study show that a certain number of variables have not been studied.

The purpose of this study, EPOLTEST 2, is to take into account the variables already studied on a larger population (18-50 years old) and to add an assessment of shoulder muscle strength and abdominolumbar endurance.

Inclusion Criteria:

• Aged to 18 to 50 years
• Capacity to consent
• Who has signed the consent

Exclusion Criteria:

• Fracture history or upper limb luxation < 1 year
• Pain or discomfort that prevents the test from being performed
• History of abdominal surgery or hernia < 1 year
• Pregnant or nursing
• Refuse to participate
• Guardianship or protection of vulnerable adult
