To date, there have been no studies evaluating any biomechanical metrics of this test. Understanding key kinetic parameters is important to evaluate the performance requirements of the test and its potential utility as a functional shoulder performance test. The objective of this study was to evaluate the rate of force development (RFD), maximal force (MF), and the time to maximal force (TMF) during the CKCUES Test. Fifteen subjects performed the test which required them to reach from hand to hand while maintaining a pushup position within a specific time period. Vertical Ground Reaction Force (VGRF) was obtained using a forceplate. Based on VGRF, RFD, TMF and MF force were calculated. Results indicate that there were no differences in the RFD, TMF and MF between analyzed touches. Thus, for this population, these kinetic variables were consistent all over the 15 seconds of test performance.

Objective Alteration of scapular position and motion is called scapular dyskinesis. Scapular dyskinesis is a common clinical problem. Strength of shoulder girdle muscles is important in shoulder motions and stability, so their weakness may lead to scapular dyskinesis. The aim of this study was to compare the maximum voluntary isometric force of shoulder girdle movements in subjects with and wit...
