Abstract

 Introduction: The PROPRIOCEPTION protects the joints injuries. It acts to increase the joint stability and during movements its critical role, inter-joint coordinator, becomes more prominent. As the force sense reproduction is one of the common methods to evaluate the PROPRIOCEPTION, its RELIABILITY is best to be evaluated. So the aim of this study was to investigate the RELIABILITY of evaluating the FORCE REPRODUCTION ERROR in dominant and non dominant sides of ELBOW extensor muscles in healthy young men.Materials and Methods: Twelve healthy young men aged between 18-30 years old were recruited for this study. They were all selected by simple convenient non probability sampling from students of rehabilitation faculty of Shahid Beheshti University of medical sciences in 1391. All participants read and signed the consent form. The intra-tester and inter-tester RELIABILITY were examined. The force meter was used to analyze the sense of FORCE REPRODUCTION ERROR in ELBOW extensor muscles. The specified percent (30%) of maximal isometric contraction was educated to subjects then asked them to reproduce the instructed force. The test was repeated just after two minutes and recorded in specific forms. The tests were measured randomly in dominant and non dominant. Relative RELIABILITY (ICC), absolute RELIABILITY (SEM) and, paired t-test were used in SPSS, version 16, to analyze the data.Results: The amounts of ICC for constant error, absolute error, and variable error in dominant (right) limb and non dominant (left) limb were in range from 0.76 to 0.94 which it shows a high RELIABILITY. The SEM measures were also in a range from 0.004 to 0.02.Conclusion: Based on the results of this study, it can be concluded that the method of evaluating the error of sense of force in both limbs of healthy young men has a high RELIABILITY. So it can be used as a reliable method in evaluating the FORCE REPRODUCTION ERROR.
