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 (IMU_sys) to measure hip and knee flexion angles. PURPOSE: To validate the use of a five-sensor IMU_sys 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 …

Outcomes Of Formalized Physical Therapy Vs. Self-Directed Home Exercise, Thomas Lee, Daniel Bowles

Phase 1

Introduction: After a formal microdiscectomy or 1-2 level anterior cervical discectomy and fusion (ACDF) there exists a lack of consensus on effectiveness of postoperative formal physical therapy (PT) rehabilitation efficacy. We seek to determine whether home PT is equivalent to standard PT using patient reported outcomes measures (PROMs) after the aforementioned operations.

Methods: This study is a prospective single center cohort study. The inclusion criteria is patients undergoing a microdiscectomy or ACDF operation excluding patients under 18, infection, trauma, tumor, or revision. Outcomes are measured using PROMs specific for each operation.

Results: Preliminary data suggests that post-operative …

Comparison Of Home Therapy Vs Formal Outpatient Physical Therapy In Post-Operative Management Of Two-Incision Distal Bicep Tendon Repair, Joseph Botros, John Horneff Iii, Md, Thomas Harper, Brent Page

Phase 1

Background: Distal bicep tendon tears are a relatively uncommon injury, affecting 1.2/ 100,000 persons per year; they can also cause substantial loss in supination and flexion strength. The most common treatment is a double incision distal bicep tendon repair, which involves surgical reinsertion of the bicep tendon onto the radial tuberosity. Following surgery, physicians have traditionally recommended the patient undergo 5-12 weeks of formal outpatient physical therapy. This can be a significant cost and time burden to the patient. Therefore, some physicians have instead opted for home physical therapy, in which the patient is given instructions on exercises to complete …

Knee Joint Loading Following Anterior Cruciate Ligament Reconstruction: Link To Patient Reported Outcomes And A Novel Method To Monitor With Wearable Sensors, Alex Spencer

Theses and Dissertations--Kinesiology and Health Promotion

Recovery from anterior cruciate ligament reconstruction (ACLR) commonly results in undesirable physical and patient-reported outcomes (PROs). Identification of modifiable factors such as knee contact force (KCF) early in rehabilitation that can improve these outcomes is important due to the rapid decrease in function, quality of life, and joint health in this population. Additionally, if noninvasive measurement of KCFs outside of a traditional laboratory were possible, clinicians could optimize patient treatment with personalized care. Therefore, there are two primary aims to this thesis: 1) quantify the link between KCF and PROs which measure pain, ability to perform activities of daily living, …
