Abstract

Čovječji hod predstavlja kvazicikličke kretnje tijela koje se ponavljaju u koracima, a čiji rezultat je kretanje tijela prema naprijed. Pri tom se može promatrati samo jedan ciklus, uz pretpostavku da su svi ostali više-manje jednaki. Iako je to samo približno točno, to je razumna pretpostavka, jer i uz sve varijacije koje se mogu opaziti kod raznih osoba ili kod iste osobe uz promjene brzine hoda, dužine koraka, vrste obuće i slično, ipak postoje brojni zajednički elementi. Mjerenje i analiza ljudskog hoda pripadaju znanstvenim i stručnim područjima kineziologije, medicine te nekoliko tehničkih disciplina, a svoju praktičnu primjenu imaju u različitim područjima od kojih, među ostalim, treba istaknuti i računalnu animaciju. Možda je najvažnija primjena vrednovanja hoda u medicinsko-dijagnostičke svrhe za dijagnostiku patoloških oblika hoda, utvrđivanje otklona, praćenje učinaka terapije, odnosno vrednovanje rezultata liječenja.
U ovom je radu razvijen standardni mjerni protokol za biomehaničko i kineziološko vrednovanje hoda automatiziranim kliničkim sustavom, predstavljene su metode obrade i prikaza signala i podataka, te su kao rezultat prikazane normativne vrijednosti parametara kinetike i kinematike hoda zdravih muškaraca srednjih godina, koji mogu biti dobra podloga odgovarajućim mjerenjima patološkog hoda. Predložen je novi način prikaza rezultata mjerenja hoda upotrebom Manal-Stanhopeovog prikaza.

Abstract (english)

Under the term gait we consider quasi-cyclical movements of the human body repeated in steps resulting in movement of the body forwards. This may be observed for a single cycle, only assuming that all the cycles are sufficiently similar. Knowing it to be approximation, it is a sound assumption because with all variations that may be observed on various subjects or on the same subject differing the gait speed, step length, footwear etc. there are still numerous common elements observed. The measurement and analysis of the human gait are part of the scientific field of kinesiology, medicine and several technical fields, and have application in many aspects among which should be mentioned the computer-aided animation. Probably the most important application is in medical diagnostic for determination of the pathologic gait patterns, identification of deflection from the norm, monitoring the therapy effects, i.e. evaluation of treatment results.
This thesis develops a standard measuring protocol for biomechanical and kinesiological evaluation of gait using an automated clinical system; it shows data and signal processing methods and it yields normative values for kinetic and kinematic parameters of gait for healthy male adults, which may be used as a reference for corresponding measurements of pathologic gait. A new way of presenting measured data is proposed using the Manal-Stanhope display.
