Power Testing: Closed Kinetic Chain Upper Extremity Test (CKCUET)

The Closed Kinetic Chain Upper Extremity Test (CKCUET) is a functional performance test used to assess an individual's upper extremity strength and stability. The test involves performing a series of weight-bearing exercises that mimic functional activities of daily living.

To perform the Closed Kinetic Chain Upper Extremity Test (CKCUET), follow these steps:

1. Instruct the client to adopt a pushup position off the long edge of the original MAT.
2. Once set, instruct the commence reaching medially across their body, touching the ride markers on the MAT on either side of their hands, as quickly as they can.
3. Ensure the client maintains a neutral spine and that they avoid shifting their weight heavily throughout this test.
4. The number of repetitions completed or the time taken to complete the test can be recorded as the score.

There is limited normative data available for the Closed Kinetic Chain Upper Extremity Test (CKCUET), as it is a relatively new test and has not been studied extensively in different populations. However, some research studies have provided reference values for the test based on the population being tested.

One study by Bottoni et al. (2003) assessed the CKCUET in a group of U.S. Military cadets. They reported mean scores of 32 repetitions for men and 21 repetitions for women over a 15-second test period.

Another study by Aspegren et al. (2007) assessed the CKCUET in a group of male handball players. They reported mean scores of 29 repetitions over a 15-second test period.
