Аннотация:Biomechanics of military crawl locomotion is poorly covered in scientific literature so far. This locomotion consists of phylogenetically old and well-automated motions, which human beings acquire at an early stage of their ontogeny and could be described as a type of quadripedal automatic locomotion [,]. Thus, crawl locomotion may be used as a testing procedure which allows detecting not only obvious, but also hidden locomotor dysfunctions. Therefore the aim of the studies was to investigate the biomechanics of crawling among healthy adult participants. Eight healthy adults aged 15-31 (4 women and 4 men) were examined by means of a 3D kinematic analysis with Optitrack optical motion-capture system. The obtained data feature the kinematics of this locomotion. Progressive and propulsive motions are characterized as normal; additional right-left side motions - with high degree of reciprocity. It was found that variability of the left-side motions is obviously lower than that of the right side. The given normative data may be used as a standard to estimate the test results for patients with various theologies.
