Therefore, the aim of this project is to create a standardized testing protocol to evaluate the functionality and usability of a prosthetic foot prototype during user testing.&#xd;
Methods: A prosthesis user was recruited to participate in a data collection using wireless insoles with imbedded force, pressure, accelerometer and angular rate sensors. Five different models of feet were tested. Information regarding the alignment of each foot were recording using a static alignment tool. User feedback and biomechanical data were recorded as participants completed a range of daily tasks and functional assessments including stair ascension and descension and variable speed walking.&#xd;
Results: Differences between the five prosthetic feet were identified, particularly with respect to range of motion and stiffness. Furthermore, user preferred alignment orientations of the feet may provide additional descriptors for differentiation.&#xd;
Conclusion: The use of the protocol allows for direct comparison and differentiation between different prototypes and competitor feet, which may provide useful information for the design of future prototype iterations, though more studies are needed.</dim:field>
<dim:field mdschema="dc" element="description" qualifier="abstract" lang="is">Inngangur: Erfitt hefur reynst að mæla mun á gervifótum með lífaflfræðilegum aðferðum, þrátt fyrir að notendur finni fyrir talsverðum mun á á þeim. Markmið verkefnisins er því að hanna staðlaða aðferð til að mæla notagildi og gagnsemi gervifótar í notendaprófun.&#xd;
Aðferð: Notandi gervifótar prófaði fimm gervifætur og var mæligögnum safnað með innleggi með skynjurum sem mældu krafta, þrýsting, hröðun og hornhraða. Upplýsingum um uppsetningu og stilling á fætinum var einnig safnað með sérsniðnu mælitæki. Upplýsingum frá notenda var safnað ásamt lífaflfræðilegum mæligögnum við venjulegt amstur, t.d ganga upp og niður stiga eða halla og göngu á mismunandi hraða. &#xd;
Niðurstöður: Mismunur greindist milli fimm tegunda gervifóta, sérstaklega m.t.t. hreyfisviðs og stifni. Einnig gefa upplýsingar um stillingar sem notendur kjósa viðbótarupplýsingar um mun á fótum. &#xd;
Ályktun: Stöðluð aðferð við prófanir á mismunandi frumgerðum og öðrum gervifótum gefur mikilvægar upplýsingar við hönnun og þróun á gervifótum.</dim:field>
