Moreover, a series of exercises were conducted by each participant across multiple sessions. Exercises were measured and recorded based on 6 distinct biometric …

Musculoskeletal Adaptation Of Young And Older Adults In Response To Challenging Surface Conditions, Amy E. Holcomb, Nicholas L. Hunt, Amanda K. Ivy, Aidan G. Cormier, Tyler N. Brown, Clare K. Fitzpatrick

Mechanical and Biomedical Engineering Faculty Publications and Presentations

Over 36 million adults over 65 years of age experience accidental falls each year. The underlying neuromechanics (whole-body function) and driving forces behind accidental falls, as well as the effects of aging on the ability of the musculoskeletal system to adapt, are poorly understood. We evaluated differences in kinematics (lower extremity joint angles and range of motion), kinetics (ground reaction force), and electromyography (muscle co-contraction), due to changes in surface conditions during gait in 14 older adults with a history of falling and 14 young adults. We investigated the impact of challenging surfaces on musculoskeletal adaptation and compared the mechanisms …

Neuromotor Control Of The Hand During Smartphone Manipulation, Prasanna Kumar Acharya

LSU Doctoral Dissertations

The primary focus of this dissertation was to understand the motor control strategy used by our neuromuscular system for the multi-layered motor tasks involved during smartphone manipulation. To understand this control strategy, we recorded the kinematics and multi-muscle activation pattern of the right limb during smartphone manipulation, including grasping with/out tapping, movement conditions (MCOND), and arm heights.

In the first study (chapter 2), we examined the neuromuscular control strategy of the upper limb during grasping with/out tapping executed with a smartphone by evaluating muscle-activation patterns of the upper limb during different movement conditions (MCOND). There was a change in muscle …

A Reticulation Of Skin-Applied Strain Sensors For Motion Capture, Christopher A. Schroeck

ETD Archive

The purpose of this research is to develop a system of motion capture based on skin-applied strain sensors. These elastic sensors are of interest because they can be applied to the body without restricting motion and are well suited to operate in more practical environments, such as sports fields, gymnasiums, and outdoor areas. This combination is currently not available in the field of motion capture. The current issues with strain sensor motion capture technology is the accurate is not sufficient for motion analysis and axial rotation monitoring of joints is not available. This project will build and test a sensor …

The Decision, Implementation And Assessment Of A Credit-Bearing Activity Class By Faculty In Residence: A Case Study, Janet Callahan, Geoff Harrison, Michael Humphrey, Cala Sielaff, Melissa Wintrow

Materials Science and Engineering Faculty Publications and Presentations

This case study reports on a programmatic decision to require a credit-bearing course that was made by Faculty in Residence (FIR), including its implementation and results over a two-year period from 2010-2012. The focus is on FIR and on the impact of their decision upon the students enrolled in their Living Learning Communities (LLCs). The credit-bearing course was a Kinesiology Activities class taken by all seven LLCs at Boise State University. Anonymous feedback from students was obtained via end of semester surveys; results were used to improve the course. Survey feedback was analyzed to assess the value students perceived to …

Adapted Pool Cue, Cole Clark, Daniel Patterson, Michelle Cheung, Dylan Sauer

Mechanical Engineering

Our primary goal was to develop an adaptive device to allow a user with limited upper body mobility to more effectively play a game of pool. Within this goal it was important to design around the concept of a least restrictive environment, in order to provide the user with as close to a standard pool playing experience as possible. The device was designed to specifically meet the needs of John Lee, an Assistive Technology Specialist at Cal Poly's Disability Resource Center. Mr. Lee has muscular dystrophy, which limits his upper and lower body mobility and currently requires his use of …

Biomechanical Analysis Of Concealed Pack Load Influences On Terrorist Gait Signatures Derived From Gröbner Basis Theory, Sean S. Kohles, Anum Barki, Kimberly D. Kendricks, Ronald F. Tuttle

Biology Faculty Publications and Presentations

This project examines kinematic gait parameters as forensic predictors of the influence associated with individuals carrying concealed weighted packs up to 20% of their body weight. An initial inverse dynamics approach combined with computational algebra provided lower limb joint angles during the stance phase of gait as measured from 12 human subjects during normal walking. The following paper describes the additional biomechanical analysis of the joint angle data to produce kinetic and kinematic parameters further characterizing human motion. Results include the rotational velocities and accelerations of the hip, knee, and ankle as well as inertial moments and kinetic energies produced …

Skeletal Muscle Contraction Simulation: A Comparison In Modeling, Jonathan M. Ford

USF Tampa Graduate Theses and Dissertations

Computer generated three-dimensional (3-D) models are being used at increasing rates in the fields of entertainment, education, research, and engineering. One of the aspects of interest includes the behavior and function of the musculoskeletal system. One such tool used by engineers is the finite element method (FEM) to simulate the physics behind muscle mechanics. There are several ways to represent 3-D muscle geometry, namely a bulk, a central line of action and a spline model. The purpose of this study is to exmine how these three representations affect the overall outcome of muscle movement. This is examined in a series …

Adaptive Floor Hockey Device, Chris Gaul, Ricardo Gaytan, Matt Spaulding, Shannon Brant

Mechanical Engineering

Sean is a young boy living with ataxic cerebral palsy. Ataxic cerebral

palsy affects Sean’s balance and coordination, so he uses a walker to

increase his mobility. Sean would like to play Special Olympics Floor

Hockey but his walker prevents him from participating. The goal of this

Senior project was to develop a device to be attached to his previous

walker to allow Sean to play floor hockey in the least restrictive

environment possible. The Adaptive Floor Hockey Device is the product

we designed to satisfy this need.

A Robotic Neuro-Musculoskeletal Simulator For Spine Research, Robb W. Colbrunn

ETD Archive

An influential conceptual framework advanced by Panjabi represents the living spine as a complex neuromusculoskeletal system whose biomechanical functioning is rather finely dependent upon the interactions among and between three principal subsystems: the passive musculoskeletal subsystem (osteoligamentous spine plus passive mechanical contributions of the muscles), the active musculoskeletal subsystem (muscles and tendons), and the neural and feedback subsystem (neural control centers and feedback elements such as mechanoreceptors located in the soft tissues) [1]. The interplay between subsystems readily encourages "thought experiments" of how pathologic changes in one subsystem might influence another--for example, prompting one to speculate how painful arthritic changes …

Effect Of Loading Condition On Traction Coefficient Between Shoes And Artificial Turf Surfaces, Seth M. Kuhlman, Michelle B. Sabick, Ronald Pfeiffer, Benjamin Cooper, Jackie Forhan

Mechanical and Biomedical Engineering Faculty Publications and Presentations

Background. The interaction between a shoe and a turf surface is highly complex and difficult to characterize. Over the three decades since artificial turf was introduced, researchers have attempted to understand the traction caused by the interaction. However, some of the methodologies used for traction measurements have not capitalized on advances in currently available technology for testing and most testing conditions have not simulated realistic physiological loads.

Method of Approach. To assess the effect of test condition on traction results, the newly designed TurfBuster testing device was used to collect traction data on FieldTurf™ brand artificial turf under varying conditions. …
