Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev Jan 2015

Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev

Graduate Theses and Dissertations

Muscular strength and power generating ability decline with advancing age. Older adults adapt their lower limb motor patterns to cope with these declines in muscle function. When mechanical demands approach limits of lower limb muscular capacity, motor patterns must be adapted to produce a desired movement. The term “motor pattern” is used to broadly represent the kinematic and kinetic profile of a person accomplishing a given task. Generally, these adaptations involve higher reliance on stronger proximal muscles to compensate for limitations or weakness of distal muscles. Three studies were conducted to examine factors affecting differences between older and young adults ...


Loading Of The Lower Extremity And Low Back When Using Wedge Orthotics During Walking And Stair Negotiation, Tami Janssen Jan 2013

Loading Of The Lower Extremity And Low Back When Using Wedge Orthotics During Walking And Stair Negotiation, Tami Janssen

Graduate Theses and Dissertations

ABSTRACT

Wedge orthotics are commonly prescribed for patients with hyperpronation and/or low back pain to improve lower limb alignment and to reduce pain. The purpose of this study was to examine the kinetic effects of medial and lateral wedge orthotics during walking and stair negotiation. Twenty-two healthy young adults participated in the study. Each participant wore no wedge (W0) as a baseline and lateral and medial wedge orthotics at 3 degrees and 7 degrees bilaterally (L3, L7, M3, M7) during walking, stair ascent, and stair descent. Ankle, knee, and hip joint moments were calculated using inverse dynamics during the ...


Medial Longitudinal Arch Mechanics Before And After A Prolonged Run, Elizabeth Rose Hageman Jan 2010

Medial Longitudinal Arch Mechanics Before And After A Prolonged Run, Elizabeth Rose Hageman

Graduate Theses and Dissertations

Collapse and reformation of the medial longitudinal arch during gait is controlled passively and actively. If either tissue group fatigues over the duration of a run, the change in arch mechanics may increase risk of running injuries. However, a 3-dimensional kinematic analysis of the medial longitudinal arch after a prolonged run has not been performed. Additionally, rarely has arch collapse been quantified for walking and running in the same study. PURPOSE: To compare arch mechanics before and after a 45 minute run and to compare walking and running arch deformation. METHODS: Thirty runners performed barefoot walking and running trials before ...
