What Do Upper-Extremity Physical Performance Tests Measure? Insights From a Descriptive Electromyographical Study.

ABSTRACT:

Background

Physical performance tests (PPTs) require athletes to complete a physical activity essential to their sports performance. Evaluating associated electromyographical requirements enables clinicians to select appropriate tests for their athletes' specific needs.

Hypothesis

Shoulder muscle activity differs between tests.

Study design

Descriptive laboratory study.

Level of evidence

Level 4.

Methods

Thirty asymptomatic overhead athletes (17 women, 13 men; mean age, 20.3 ± 1.7 years) performed 4 upper-extremity PPTs: Y-balance test-upper quarter (YBT-UQ), closed kinetic chain upper extremity stability test (CKCUEST), upper limb rotation test (ULRT), and shoulder endurance test (SET). Surface electromyography, expressed as a percentage of the maximal
