PURPOSE It seems that there is an association between the anterior cruciate ligament (ACL) and stability of the knee. This study aimed to evaluate the balance condition of the injured and non-injured sides of the coper and non-coper ACL-D (deficient) subjects during single and bilateral standing conditions. METHODS This case-control study was carried out on 10 coper and 5 non-coper ACL-D knee...

objectives: the aim of the present study was to compare the performance of the vertical jump task and the level of disability between the coper and non-coper athletes with an anterior cruciate ligament-minus knee. methods: thirty-four professional male athletes with isolated complete anterior cruciate ligament-tear (age 20-29 years and 6-12 months time past injury) were recruited in this study....

Purpose: It is essential to maintain dynamic stability during walking to perform daily tasks independently. The present study aimed at comparing the spatiotemporal parameters and the values of the vertical ground reaction force (vGRF) as well as determining the time to reach them in ankle-sprain coper and healthy athletes during the stance phase of gait. Methods: A total of 28 female universit...

This paper deals with computer generation of numerical functional formulas describing results of scientific experiments (measurements). It describes the methodology for generating functional physical laws called COPER (Kokar 1985a). This method generates only so called "meaningful functions", i.e., such that fulfill some syntactic conditions. In the case of physical laws these conditions are de...

OBJECTIVE The study aimed to explore latent profiles of coping in Chinese women newly diagnosed with breast cancer and examine the differences of psychological distress, demographic, and medical characteristics across profiles. METHODS Latent profile analysis was used to identify 3 classes of copers based on data from 618 Chinese women newly diagnosed with breast cancer who completed question...

Ankle sprain is one of the most commonly damaged lower extremities. More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (Coper people) and do not suffer from chronic ankle instability. The aim of this study was to compare EMG activity of the selected involved muscles in balance control strategies in athletes with c...

TO THE EDITOR: We would like to point out inaccuracies in the interpretation and application of our work in a recent article by Melynk et al. (2007) that reported on changes in stretch reflex excitability after anterior cruciate ligament (ACL) rupture. Subjects were divided into two groups (“coper” and “noncoper”) based on responses to four questions about the subjective symptom of knee giving ...

Compressive phase retrieval is the problem of recovering a structured vector x ∈ C from its phaseless linear measurements. A compression algorithm aims to represent structured signals with as few bits as possible. As a result of extensive research devoted to compression algorithms, in many signal classes, compression algorithms are capable of employing sophisticated structures in signals and co...
