Assessing The Repeatability Of Clinical Tests In People With And Without Flexion-Induced Neck Pain, Ashton Human Dec 2019

Assessing The Repeatability Of Clinical Tests In People With And Without Flexion-Induced Neck Pain, Ashton Human

Graduate Theses and Dissertations

The accessibility of mobile technology has improved productivity but can contribute to musculoskeletal disorders due to the posture associated with using such devices. Neck flexion, a posture assumed by smartphone users, has been shown as a risk factor for the development of clinical neck pain if sustained for prolonged periods. Determining the individuals who are naturally more predisposed to develop flexion-induced neck pain can aid in the prevention and treatment of musculoskeletal disorders. The purpose of this thesis is to assess the repeatability of clinical tests between trials over the course of two days in young adults who do and …

The Business Case For Industrial Safety: Revealing The Comprehensive Value Of Ergonomic Investments For Manufacturing Enterprises In Industry 4.0, Shane Stan Oct 2019

The Business Case For Industrial Safety: Revealing The Comprehensive Value Of Ergonomic Investments For Manufacturing Enterprises In Industry 4.0, Shane Stan

Honors Program: Senior Projects (Public)

How can today’s manufacturing enterprises construct, implement, and optimize modern safety initiatives in a manner that will present maximum return on investment and facilitate enterprise growth? Furthermore, how can these manufacturers assure individual ergonomic investments become part of a larger strategy to facilitate organizational change in safety? This work addresses these questions by placing industrial ergonomics in a business improvement context which comprehensively presents the financial returns and growth opportunities poised by modern safety initiatives. Additionally, to further strengthen the business case for industrial safety, an ergonomic action planning framework is established to guide the creation of holistic safety programs …

A Design For Affordances Framework For Product Packaging: Food Packaging Case Study, Ahmad Abdelhafiz Mumani, Richard T. Stone, Esraa Abdelall Jan 2019

A Design For Affordances Framework For Product Packaging: Food Packaging Case Study, Ahmad Abdelhafiz Mumani, Richard T. Stone, Esraa Abdelall

Journal of Applied Packaging Research

Since affordances provided by packaging features play a major role in facilitating user packaging interaction, it is important to integrate the concept of affordances into the packaging design process and to understand the interrelationships between packaging features and affordances. A framework is proposed for linking user requirements to packaging design features utilizing the concept of affordances. The framework is accomplished in two main steps; first, determine the affordances required to facilitate performing packaging-related tasks, and second, link these affordances to packaging features. Previous packaging usability studies were reviewed to elicit requirements in terms of affordance properties such as intuitiveness, responsiveness, …

Can Fitts' Throughput Be A Predictor Of Muscle Fatigue – A Study Based On Metacarpal Gloves?, Sachin Sah Jan 2019

Can Fitts' Throughput Be A Predictor Of Muscle Fatigue – A Study Based On Metacarpal Gloves?, Sachin Sah

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this study, Fitts’ throughput was used to estimate throughput for metacarpal gloves. Fitts’ throughput combines speed and accuracy during target transfer/movement tasks into a single performance index. It was hypothesized that the throughput will be affected by the glove condition and it will exhibit a relationship with the physiological response of hand muscles and perceived exertions. Fifteen healthy participants (10 males, 5 females) were recruited for data collection. Each participant performed a series of target transfer tasks using four glove conditions: (1) a pigskin leather (glove 1); (2) a synthetic fiber glove (glove 2); (3) a goat-grain leather glove …

Development Of A Task Analysis Tool To Estimate Shoulder Strain During A Lifting Task, Christopher Wayne Moore Jan 2019

Development Of A Task Analysis Tool To Estimate Shoulder Strain During A Lifting Task, Christopher Wayne Moore

Graduate Theses, Dissertations, and Problem Reports (ETD)

Musculoskeletal disorders of the shoulder have a huge impact on the workplace and employees. Due to the complexity and high mobility of the shoulder, developing a task analysis tool with a focus on the shoulder is difficult, and while there are some ergonomic analysis tools that do consider the shoulder to varying degrees in the analysis, none focus purely on the shoulder. Therefore, this research was undertaken in an attempt to develop a shoulder-based task analysis tool for the shoulder. However, since the scope of work involving the shoulder is so vast, the tool in this research focuses on unobstructed, …
