Effects Of Physical Exertion And Alignment Alterations On Trans-Tibial Amputee Gait, And Concurrent Validity Of Prosthesis-Integrated Measurement Of Gait Kinetics, Goeran Fiedler
Theses and Dissertations
This study investigated the effects of slight changes in the alignment of the artificial limb of trans-tibial amputees on the walking pattern on the level of forces and moments, particularly when physical exertion levels increase. Two alignment conditions were assessed in ten trans-tibial amputees while walking with low and with "strong" levels of exertion. Two separate data collection methods were utilized simultaneously: a conventional motion analysis, and continuous recordings from prosthesis-integrated force sensors. While the former was used to compare bilateral leg symmetry across conditions, the latter allowed analyzing unilateral step variability within subjects. This paper presents both analyses in …
