Introduction: Proprioception is a fundamental part of the somatosensory system and is important in identifying proprioceptive deficits. The test for joint position remains the most widespread method of measuring proprioception, using various devices such as digital and isokinetic goniometer, electro goniometer, dynamometer, inclinometer and 3D systems to perform measurements. Most often, the joint position sense of the knee joint is assessed in the position of the open kinetic chain, but the assessment in the position of the closed kinetic chain is also recommended, as it is more functional. Purpose: The purpose of this thesis is to present the reliability of knee joint position sense measuring in a closed and open kinetic chain, based on a review of the literature. Methods: The literature was found in the PubMed database using various combinations of keywords in English and by individual search in the references of published sources. Results: Eight studies were included in the literature review in which authors examined the reliability of knee joint position sense measuring in a closed and/or open kinetic chain. Healthy individuals between the ages of 18 and 60 participated in the research. The research examined intra-examiner, inter-examiner and test-retest reliability. Measurements in the open as well as in the closed kinetic chain showed high reliability scores. Discussion and conclusion: In knee joint position sense measuring, the inclinometer proved to be the most reliable, affordable and practical compared to the dynamometer. Performing measurements in both closed and open kinetic chains showed reliability. In the closed kinetic chain, there is a greater activation of mechanoreceptors, while the open kinetic chain represents an isolated sense of the position of the knee joint.
