Diffusion tensor imaging (DTI) using a combination of direct anisotropy measurements provided a more anatomically accurate morphological representation of the human spinal cord than traditional anisotropy indices. Furthermore, the use of a fuzzy logic algorithm to segment regions of gray and white matter within the spinal cord based on these anisotropy measurements allowed for morphometric analyses...
We identified torque response of flexion reflex associated with hip angle and angular velocity in 6 subjects with chronic SCI and developed two dimensional dynamic model with three segments, thigh, shank and foot. Influences of stimulation parameters such as amplitude, frequency and duration time of pulse train for producing swing motion of lower limb were investigated with response surface method...
Following spinal cord injury (SCI), morphological changes in the spinal cord are observed at the clinically diagnosed level of injury, as well as at segmental levels above and below the injury site due to axonal degeneration. In order to quantify the extent of morphological changes, a three dimensional segmentation of the spinal cord was constructed using magnetic resonance images (MRI) of the cervical...
