Clinical Trial Summary

Cervical myelopathy (CM), a chronically compressive spinal cord lesion, is the most common cause of non-traumatic paraparesis/quadriparesis among the elderly. Hong Kong is facing a heavy social economic burden from CM with the rapidly aging population. Surgical decompression is considered as the mainstay of the treatment for CM patients to relieve their symptoms and signs. Yet the surgical outcome is not always satisfactory. There is a pressing need for understanding the exact mechanism of surgical decompression on the recovery of myelopathic cord in order to improve the prognosis of CM patients in near future.This project will evaluate neuronal activities and axon regeneration by longitudinally monitoring at time zero, 3 and 6 month after the surgery in CM patients using UTE, BOLD-fMRI and DTI, and to investigate the relationship of preoperative neuronal activities of myelopathic cord with axon regeneration.


Clinical Trial Description

This study aims to monitor the structural and functional changes of chronically compressed spinal cords longitudinally after surgical decompression in vivo. Three kinds of MRI techniques will be used in this study. These are (1) axial T1-weighted (T1WI) and T2-weighted imaging (T2WI), UTE MRI, (2) BOLD-based fMRI, and (3) diffusion tensor imaging (DTI). To quantitatively investigate the structural deficits, T1/T2 MRIs will delineate the gross morphology of the spinal cord, CSF, and surrounding anatomical structures, while DTI will quantify the fiber orientation and integrity within the spinal cord. BOLD-based functional MRIs will assess the local hemodynamic changes and neuron activities in response to the motor or sensory stimulation along the C3 to C8 spinal nerve levels. The MRI evaluations will be applied to the same cervical myelopathy (CM) patient before surgery and 3 and 6 months post-surgery, when clinical recovery reaches a plateau9. Clinical examination will include neurological evaluation, Japanese Orthopaedic Association (JOA) scoring assessment, and clinical electrophysiological evaluation. ;
