[Swing-through gait from the perspective of biomechanics and kinesiology. Critical analysis of the current state of knowledge and the idea behind the research].

The study defines the idea behind the research project which analyzes the swing-through gait from the biomechanical and kinesiological perspective. In the preliminary phase, the authors performed a synthetic analysis of the state of knowledge, created a description of the general kinematic structure of the swing-through gait as a form of locomotion with the use of crutches, proposed definitions. The problem was described with the use of time characteristics of vertical and horizontal anterior-posterior as well as lateral components of ground reaction forces, measured from under the supporting limb and the crutches. Presenting the idea behind the research project, the authors defined in detail the purpose of the study, the assumptions, research methodology--including a description of methods used and the measurement channels which consisted of: 2 AMTI force platforms integrated into a measurement walkway, a set of 6 optoelectronic cameras of the BTS System as well as a multichannel kinesiologic electromyography performed with the use of the NORAXON System. All phases of the research were characterized, presenting the research protocol in its entirety. The research will be conducted in the Laboratory of the Department of Biomechanics of USPS in Poznan, which possesses the ISO 9001:2008 quality management system certificate.
