Closed Kinetic Chain Upper Extremity Stability Test

Last Updated

October 29, 2015

Purpose

The Closed Kinetic Chain Upper Extremity Stability Test is a low-cost performance test that provides quantitative data (scores) for an upper extremity task in closed kinetic chain with no need for high technology to be realized in sportive or clinical settings. It can help to determine deficits in closed kinetic chain upper extremity functional performance.

Diagnosis/Conditions

Sports & Musculoskeletal Injuries

Mixed Populations

Patients assume the push-up position, with hands set 36 inches apart, and are scored based on the number of times the patient is able to pick one hand up and swing it across their hand stance and touch the supporting hand in a 15 second period.
Females can perform the test in a modified (kneeling) push up position.

Considerations

Goldbeck & Davies, 2000
- Contraindications to perform the test include elderly age and patients with wrist/ elbow pathologies or posterior instabilities of the shoulder.
Hegedus, 2014
- Reproducibility, validity, and responsiveness are not established. Caution should be exercised in the clinical interpretation of CKCUEST in relationship to risk assessment or as a stand-alone diagnostic tool for upper extremity sports-related injury.
Roush, 2007
- Patients with comorbidities of the upper extremities may have difficulty performing the task. The older geriatric population may be unable to perform the test, and patients who are at risk of fracture may have an increased risk due to the force of impact.

Tucci, 2014
- Some healthy subjects reported pain after the test even with no pain reported before the test, thus clinicians should have care when the test is considered in the initial evaluation of a subject with shoulder injury.

Cut-Off Scores

Athletes (Hegedus, 2014)

In a small, single-center trial, a cut score of <=24 discriminated between non-injured and injured collegiate baseball players with upper extremity sport-related injury. However, this cut score has poor diagnostic utility (sensitivity=0.72, specificity=0.69, positive likelihood ratio=2.3, negative likelihood ratio=0.39).
