Description

Methods for Biomechanical Analysis of Amputee Gait and Activities of Daily Living / John Deckert, Omid Jahanian MS, Liana Hawi, Alyssa Schnorenberg MS, and Brooke Slavens PhD, / / Correctly identifying the proper alignment and components of an amputee’s prosthesis is incredibly important for the prosthetist. Even slight changes in the alignment of an amputee’s prosthesis can change the person’s overall biomechanics and thus their kinematics during ambulation. While current methods are based on observation alone, we propose methods using quantitative motion analysis. Data acquisition and processing methods can be applied to calculate the amputee’s joint dynamics in order to facilitate human movement. This project will investigate the biomechanics of amputee mobility during various activities of daily living. The subjects will undergo motion analysis (with a 14 camera Vicon system; using a Plug-in-Gait model and 39 retro-reflective markers) during a variety of mobility tasks including self-selected gait, ascension and descension of stairs, walking with a backpack, ramp inclined and declined planes, sit-to-stand, and stand-to-sit activities. Data from the motion analysis will be processed using Vicon Nexus 2.1 software for labeling, filling gaps in the data, and filtering the kinematic trajectories. Vicon Plug-in-Gait model will be used to calculate lower and upper extremity joint angles, joint forces, and joint moments. This data will be used to identify variations in the joint parameters and spatiotemporal gait parameters (speed and cadence). Impact of this work extends to all amputees for improved rehabilitation treatment through quantitative assessment of activities of daily living. Ultimately, this work will assist prosthetists in the care of their patients. /
