Chair Rise Kinetics And Correlates Of Performance In Young And Older Males, Tyler Smith

Symposium of Student Scholars

Purpose: To compare chair rise kinetics in young (YM) and older (OM) males, and determine correlates of chair rise performance. METHODS: YM (n=15, age =20.7±2.2 yrs) and OM (n=15, age=71.6±3.9yrs) performed three trials of a single chair rise as quickly as possible on a force plate and the vertical ground reaction force (VGRF) signal was analyzed. Peak VGRF (PF), as well as peak (100 ms rolling average), early (minimum VGRF to 50% PF), late (50% PF to PF), and overall (minimum VGRF to PF) rate of force development (RFD; Δforce/Δtime) were calculated based on phases of the task. Power and …

Efficacy Of The Opensim Simulator As A Tool To Detect Changes In Gait: A Peripheral Artery Disease Model, Cody Anderson, Hafiz Rahman, Irakis Pipinos, Jason Johanning, Sara Myers

UNO Student Research and Creative Activity Fair

INTRODUCTION

Peripheral Artery Disease (PAD) is characterized by atherosclerotic plaques in the leg arteries. A common treatment for PAD is supervised exercise training [1]. However, gait is not fully restored following supervised exercise training (SET). Musculoskeletal simulation may provide insight into how muscle activation changes following SET contributed to persistent gait alterations.

METHODS

Kinematic and kinetic data from overground walking of patients with PAD (n=12), before and after a 6-month exercise intervention, was used as input for musculoskeletal modeling (OpenSim). The subjects in our sample were subdivided based on the location of ischemic muscle pain, as reported on the San …
