20.500.12556/RUL-187090 Izdelava in testiranje karbonskega vložka za čevelj po transmetatarzalni amputaciji diplomsko delo Developing and testing of carbon shoe insole following transmetatarsal amputation diploma work Uvod: Stopalo je kompleksna anatomska struktura, ključnega pomena za gibanje in stojo. Sestavlja ga niz 26 v obok povezanih kosti, ki skupaj z mišicami in vezmi omogočajo statiko in dinamiko, prav tako pa omogočajo prenašanje in razporeditev sil, ki nastajajo pri hoji. Stopalo vsebuje tri stopalne loke, ki so sposobni shranjevanja dela energije. Shranjeno energijo sprostijo v fazi odriva in s tem pomagajo pri energetsko bolj učinkovitem gibanju. Ta sistem se poruši pri transmetatarzalni amputaciji stopala. Čeprav je hoja še zmeraj mogoča, je ta tipično nesimetrična, koraki pa so krajši. Del funkcije lahko povrnemo z različnimi protetičnimi rešitvami, med drugim individualno izdelanimi in prilagojenimi ortopedskimi čevlji, silikonskimi protezami in karbonskimi vložki. Karbonu njegove mehanske lastnosti omogočajo določeno stopnjo shranjevanja energije, zato ga lahko uporabljamo kot vrsta vzmeti, ki lajša gibanje in izboljšuje funkcijo odriva pri hoji. Namen: Namen tega diplomskega dela je izdelati individualno prilagojen karbonski vložek za osebo s transmetatarzalno amputacijo stopala ter oceniti vpliv vložka na biomehaniko hoje. Prav tako je bila narejena primerjava izdelanega karbonskega vložka z drugimi pripomočki, ki jih preiskovanec uporablja, ter na podlagi rezultatov oceniti uporabnost karbonskega vložka. Metode dela: Metode dela so zajemale pregled literature ter praktično izdelavo in testiranje individualno izdelanega karbonskega vložka. Prav tako je bila narejena analiza hoje s silikonsko protezo in ortopedskimi čevlji z vgrajenim karbonom. Rezultati: Med rezultati testiranj posameznih pripomočkov ni bilo večjih razlik v časovno–prostorskih parametrih hoje. Največje razlike so se pojavljale pri meritvah, povezanih z gibom pronacije in moči. Pri drugih parametrih so bile razlike manj izrazite. Razprava in zaključek: Rezultati so pokazali, da karbonski vložek ni bistveno vplival na časovno–prostorske parametre pri hoji na krajše razdalje, je pa zmanjšal obseg in hitrost giba pronacije v fazi osrednje opore ter spremenil porazdelitev največjih obremenitev med stopali. Ugotovitve kažejo, da karbonski vložek predstavlja učinkovito rešitev za osebe s transmetatarzalno amputacijo stopala in ima dober potencial za nadaljnje raziskave. Introduction: The foot is a complex anatomical structure, crucial for movement and stance. It consists of 26 bones connected in an arch, which together with muscles and ligaments provide both static and dynamic mobility, as well as transmit and distribute the forces, generated during walking. The foot contains three plantar arches, capable of storing some of the energy. The energy is released during the push-off phase, contributing to more efficient movement. This system is disrupted by a transmetatarsal foot amputation. Although walking is still possible, it typically becomes asymmetric with shorter steps. Part of the lost function can be restored using various prosthetic solutions, such as custom-made orthopaedic shoes, silicone prostheses and carbon insoles. Because of its mechanical properties, carbon can store a certain amount of energy and act like a sort of spring, facilitating movement and improving the push-off function during walking. Purpose: The aim of this thesis was to design a custom carbon shoe insole for a person with a transmetatarsal foot amputation and to assess its impact on gait biomechanics. The carbon insole was also compared with other aids that the test subject currently uses, in order to evaluate its usability and effectiveness. Methods: Methods included a literature review and the practical manufacturing and testing of the custom carbon insole. A gait analysis was preformed using accelerometers with the subject’s silicone prosthesis and with shoes, which had an integrated carbon fiber element. Results: The results showed no significant differences in the spatio-temporal parameters of gait among the devices tested. The largest differences were found in measurements related to pronation range and velocity, as well as in the generated power. Differences in other parameters were less pronounced. Discussion and conclusion: The findings indicate that the carbon insole did not significantly affect the spatio-temporal parameters during short-distance walking, but it did reduce the magnitude and rate of pronation during mid-stance and altered the distribution of peak pressures between the feet. These results suggest that the individually designed carbon insole can be an effective solution for individuals with a transmetatarsal foot amputation and has good potential for further research. diplomska dela ortotika in protetika biomehanika karbonski vložki parcialna amputacija pospeškomeri transmetatarzalna amputacija diploma theses orthotics and prosthetics biomechanics carbon insoles partial foot amputation accelerometers transmetatarsal amputation true false false [U.
