Investigating Cortical Changes In Cervical Spondylotic Myelopathy Using Functional Magnetic Resonance Imaging, Proton Magnetic Resonance Spectroscopy And Diffusion Tensor Imaging, Izabela Kowalczyk

Electronic Thesis and Dissertation Repository

Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in older adults. CSM can present abruptly with severe symptoms of neurological impairment or insidiously with a slow stepwise deterioration. There is no current imaging modality or biomarker that can help predict which patient will successfully respond to conservative versus surgical treatment. The goal of this thesis was to follow CSM patients longitudinally to assess how brain function, metabolism, and structure correlate to clinical outcomes in the context of recovering neurological function following surgery.

Chapter 1 of this thesis will provide a detailed literature review of the …

Resting State Functional Magnetic Resonance And Diffusion Tensor Imaging Of Hemiplegic Cerebral Palsy Patients Treated With Constraint-Induced Movement Therapy: Predictors And Clinically Correlated Evidence Of Neuroplasticity, Kathryn Y. Manning

Electronic Thesis and Dissertation Repository

Hemiplegic cerebral palsy is characterized by unilateral upper limb impairment and patients often compensate by performing most tasks with their unaffected arm. Constraint-induced movement therapy (CIMT) directly combats this learned non-use by casting the unaffected arm and forcing the patient to repetitively practice skills with the hemiplegic limb. Subjects with hemiplegic cerebral palsy were recruited from Holland Bloorview Kids Rehabilitation Hospital, Thames Valley Children’s Centre and McMaster Children’s Hospital. MRI acquisitions and clinical evaluations were collected at baseline, 1 and 6-months later. The case group participated in a CIMT camp after baseline evaluations and was compared to an untreated control …
