Comparative Kinematic Gait Analysis In Adults With Multiple Disabilities, Lauren Rumbalski

Undergraduate Honors Thesis Projects

The purpose of this research is to identify abnormal gait parameters or patterns amongst young adults with multiple disabilities enrolled in a work transition program sponsored by a public-school system. Gait disorders are commonly seen in individuals with neurologic disorders, with significant research in children with autism. Gait disorders have been linked with fall and injury risk, with significant research in elderly populations. Gait analysis technology can be used to identify gait characteristics in populations that are abnormal or contribute to gait disorders. In an observational design, students from the transitional program promoted by Westerville City Schools, housed on Otterbein …

Biomechanical Analysis Of Ligament Modelling Techniques And Femoral Component Malrotation Following Tka, Liam A. Montgomery

Electronic Thesis and Dissertation Repository

Previous studies have demonstrated that satisfaction and revision rates following total knee arthroplasty (TKA) are lower than those of comparable surgeries such as total hip replacements. A leading cause for these revisions is joint instability which may be due to improper ligament balancing or poorly aligned surgical implants. One of the methods used to investigate biomechanical forces and kinematics is computational modelling of the post-operative TKA knee.

A unique knee model was used to investigate the biomechanical and kinematic effects of ligament model complexity, as well as the effects of simulating ligament wrapping versus ignoring ligament wrapping. We then used …

Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus

Electronic Thesis and Dissertation Repository

Tremor commonly affects the upper extremities in essential tremor (ET) and Parkinson disease (PD) patients where many experience functional disability and ultimately seek therapy. As ET and PD tremor features overlap and clinical assessment is challenging due to its highly complex nature, misdiagnosis is common resulting in unsuitable therapies and prognosis. Current treatment options for ET and PD tremor include pharmacotherapy, focal therapy with botulinum toxin type A (BoNT-A) injections, and surgical interventions which provide modest relief of tremor. However, such therapies are commonly associated with significant adverse events and lack long-term efficacy and tolerability. Hence lack of standardized, objective …

Determination Of The Functional Relationship Between Lumbar Lordosis And Pelvic Tilt, Casey Tyler Hebert

Theses and Dissertations (ETD)

Americans are undergoing spinal fusion surgery (SFS) at an ever increasing rate; in 2008 over 400,000 Americans underwent SFS with a national cost of approximately $33.9 billion. During SFS it is difficult for the surgeon to properly align the spine’s s-shape, as viewed from the patient’s side. Abnormal alignment of the spine then alters the position of the pelvis and hip joints, which may impact the function and hip contact patterns. Several studies have shown that patients with spinal pathology, such as arthritis, often have a coexisting hip pathology or subsequently develop hip pathology, and it is estimated that 18% …

Development And Application Of A Biorobotic Simulation Of Stance Phase Gait To Study Foot And Ankle Kinematics, Kelly N. Salb

Theses and Dissertations (ETD)

Ankle instantaneous axis of rotation (IAR) measurements represent a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a major role in ankle biomechanics, including influences on articular surfaces, bony motion, and formation of the arches, studies concerning the effects of joint loading are limited.

A novel testing protocol was developed to simulate in vivo mechanics of the foot-ankle complex during early stance phase gait in a human cadaveric model. Two studies were conducted. The first study was to assess …

Kinematic And Spatiotemporal Analysis Between Sprint Drills And Maximal Sprinting, Julianne Cappadona

PTHMS Undergraduate Publications

Purpose: To determine if any kinematic differences exist between two common sprint drills (A- and B-drills) and maximal sprinting. Methods: 12 collegiate sprinters (19.17±1.11 y/o) granted informed consent were filmed performing two 40-meter sprints, A-skips, and B-skips. Three-dimensional motion analysis tracked the coordinates of 24 reflective markers and resulting joint kinematics were computed. Results: Statistical analysis revealed that sprinting yielded a significantly lower maximum hip flexion (p=0.015) but a significantly higher minimum ankle angular velocity (p=0.012) and step rate (p=0.000) value than A-drills. When compared to B-drills, sprinting values were significantly lower in maximum hip flexion (p=0.047), minimum knee flexion …

The Use Of Motion Analysis Technology As An Alternative Means Of Assessing Spinal Deformity In Patients With Adolescent Idiopathic Scoliosis, Matthew J. Solomito

Master's Theses

Adolescent Idiopathic Scoliosis (AIS) is a three dimensional deformity of the spine that causes abnormal curvatures in the coronal and sagittal planes and abnormal vertebral rotations. The gold standard for diagnosing and tracking the progression of the deformity is through the use of repeated radiography and a patient can receive upwards of fifteen radiographic series over the course of treatment, which exposes this population to an increased risk of radiation-dependent complications.

This thesis presents the necessary calculations and the marker set required to make the motion capture technology a viable alternative to radiographs, in an effort to reduce the patient’s …

A Kinematics-Based Testing Protocol To Study The Mechanics Of The Human Lumbar Spine, Nephi A. Zufelt

Theses and Dissertations (ETD)

The objective of this work was to develop a new kinematics-based testing protocol to quantify the axial and shear force components and rotational moment properties of the human cadaveric lumbar motion segment unit (MSU) in response to specific kinematic inputs. Modern, non-fusion spinal devices claim to treat degenerative disc disease better than traditional fusion surgery. Though there have been many biomechanical studies completed on these devices, there is still a debate over their efficacy. Conventional testing methods provide insight into the rotational properties of the MSU but lack the sensitivity or capacity to quantify lumbar MSU’s mechanical properties including shear …
