Validation Of An Inertial-Measurement-Unit System For Calculating Hip And Knee Flexion Angles During Gait, Joonsun Park
Validation Of An Inertial-Measurement-Unit System For Calculating Hip And Knee Flexion Angles During Gait, Joonsun Park
Master's Theses
Technological advances regarding Inertial Measurements Units (IMUs) have positioned this type of sensor as an alternative for camera-based motion capture. This study introduces a new IMU based system (IMUsys) to measure hip and knee flexion angles. PURPOSE: To validate the use of a five-sensor IMUsys for the measurement of knee and hip flexion angles during gait in adults and pediatrics at two different time points. METHODS: Bilateral hip and knee flexion patterns (LH, RH, LK, and RK) of twenty-two healthy participants (12 adults and 10 pediatric) between the ages of 8 – 35 years were investigated. Participants …
The Symbiome Project: An Exploratory Investigation Of The Biological, Psychological, And Social Mechanisms That Contribute To The Transition From Acute To Chronic Musculoskeletal Pain, Joshua Y. Lee
Electronic Thesis and Dissertation Repository
This dissertation presents the initial findings of the SYMBIOME project; which attempts to combine the objective and subjective aspects of musculoskeletal pain to develop a prognostic clinical phenotype. Chapter 2 presents a moderator analysis of functional outcomes (pain interference and pain severity). Psychosocial moderators can affect the relationship between biomarkers and pain. For pain severity, TNF-α, TGF-β1, and CRP were moderated by employment status, pre-existing psychopathology, and sex. For pain interference, IL-1β, cortisol, TGF-β1, CRP, and IL-6 were moderated by pre-existing pain, peri-traumatic fear, region of injury, and peri-traumatic stress. Chapter 3 presents a latent growth curve analysis in determining …
