The hamstring muscle group is a vital constituent to injury prevention and lower extremity rehabilitation. During closed chain activity, hamstring muscle fibers influence dynamic interaction between the pelvis, sacrum, femur and lower leg. The hamstring muscle group functions as a frontal and transverse plane stabilizer, influencing knee flexion deceleration and eccentric extension during forwa...

This paper consider optimization decision-making of closed-loop supply chain based on revenue sharing contract and prospect theory, and study the effect of lose aversion on the performance of closed-loop supply chain. We establish a decision-making model for the closed-loop supply chain which consists a loss averse retailer and a loss averse manufacturer. Through the analysis of this model unde...

Based on analyzing the difficulties of closed-loop supply chain operation management, considering the new environment as the economic society developing continuously and discussing the feasibility of virtual enterprise, an operation management mode for the closed-loop supply chain based on virtual enterprise is presented in this paper. The organization framework, the operational process, the dy...

[Purpose] The purpose of this study was to examine the effect of closed kinetic chain exercises performed by an unstable exercise group (UEG) and a stable exercise group (SEG) on the knee joint, proprioception, and functional scores of patients who underwent anterior cruciate ligament (ACL) reconstruction. [Subjects] Twenty-eight patients participated in this study. The exclusion criteria were ...

BACKGROUND The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) has been proposed as an option to assess upper limb function and stability; however, there are few studies that support the use of this test in adolescents. PURPOSE The purpose of the present study was to investigate the intersession reliability and agreement of three CKCUEST scores in adolescents and establish clini...

BACKGROUND The Close Kinetic Chain Upper Extremity Stability Test (CKCUES test) is a low cost shoulder functional test that could be considered as a complementary and objective clinical outcome for shoulder performance evaluation. However, its reliability was tested only in recreational athletes' males and there are no studies comparing scores between sedentary and active samples. The purpose w...
