Study Summary
In human gait there is a certain amount of variation between steps; some considered physiological and owed to variations in environment or posture, and some severe enough to be indicative of gait instabilities that may lead to stumbling and falling. In users of lower limb prosthetics, such gait instabilities are of especially great interest. The study investigates the correlation between socket alignment quality and gait step-by-step variability in users of trans-tibial-prosthetics. It is hypothesized that a clearly defined range of step-by-step variability exists, and that therefore step-by-step variability is suitable as an outcome variable for the assessment of socket alignment. A sample of ten persons with trans-tibial amputation will be recruited for this pilot study. Subjects will be asked to walk on different natural surfaces while the socket alignment is successively perturbed. Step-by-step variations in horizontal ground reaction forces and torsional moments will be measured and statistically compared.
Primary Outcome
Peak horizontal ground reaction force (Fx and Fy) as well as peak axial torsion moment (Mz) will be extracted for 10 consecutive intermediary steps for each testing condition. Total range in Newtons over the 10 step sample, as well as maximal difference between consecutive steps in Newtons and percent will be reported for statistical analysis.
