Motor development depends on forming specific connections between the corticospinal tract (CST) and the spinal cord. Blocking CST activity in kittens during the critical period for establishing connections with spinal motor circuits results in permanent impairments in connectivity and function. The changes in connections are consistent with the hypothesis that the inactive tract is less competi...

OBJECTIVES Direct injury to the corticospinal tract (CST) is a major factor defining motor impairment after stroke. Diffusion tensor imaging (DTI) tractography allows definition of the CST. We sought to determine whether DTI-based assessment of the degree of CST damage correlates with motor impairment at each phase of ischemic stroke. METHODS We evaluated patients at the acute (3-7 days), sub...

Information Richness Theory (IRT) has enjoyed acceptance by information systems researchers throughout the last decade, but recent unfavorable empirical evidence has precipitated a shift away from it and a search for a new theory. Because of this shift, a new definition of communication richness is needed to succeed the IRT definition. Since its inception, IS research on communication richness ...

BACKGROUND Traumatic spinal cord injury (SCI) leads to disruption of axons and macroscopic tissue loss. Using diffusion tensor imaging (DTI), we assessed degeneration of the corticospinal tract (CST) in the cervical cord above a traumatic lesion and explored its relationship with cervical atrophy, remote axonal changes within the cranial CST and upper limb function. METHODS Nine cervical inju...

BACKGROUND Reorganization of the corticospinal tract (CST) can occur in unilateral spastic cerebral palsy (USCP). The affected hand can be controlled via (1) typical contralateral projections from the lesioned hemisphere, (2) ipsilateral projections from the nonlesioned hemisphere, and (3) a combination of contralateral and ipsilateral projections (ie, bilateral). Intensive bimanual therapy and...

Changes in the distribution of the proton magnetic resonance spectroscopy (MRS) observed metabolites N-acetyl aspartate (NAA), total-choline (Cho), and total-creatine (Cre) in the entire intracranial corticospinal tract (CST) including the primary motor cortex were evaluated in patients with amyotrophic lateral sclerosis (ALS). The study included 38 sporadic definite-ALS subjects and 70 age-mat...

The current study compares outcomes of modified cartilage shield tympanoplasty (CST) with temporalis fascia tympanoplasty in type I procedures in Indian patients. Graft uptake rates are better with the CST technique and hearing results are almost equivalent with both techniques except at 8000 Hz where improvement in hearing was found better with the use of temporalis fascia alone. The CST techn...

Objectives: Complementary and alternative medicine methods (CAM) are now used for a wide range of disorders. Craniosacral therapy (CST) is one of CAM methods in which manual maneuvers with light forces are used for different aspects of health. In the present research, the effects of CST were studied for reducing symptoms of attention deficit and hyperactivity disorder (ADHD). Methods: Twenty...

The Circuit Switched Tree (CST) has been shown to be an important interconnect for dynamically reconfigurable architectures, on which several problems have extremely fast solutions. A vital component of communicating through the CST is the configuration of its switches. In this paper, we present configuration algorithms for two classes of CST communications: oriented, well-nested sets and multi...

PURPOSE The purpose of this study was to determine whether eyes with center-involved diabetic macular edema, treated with focal/grid photocoagulation, in which there is a reduction in central subfield thickness (CST) measured with optical coherence tomography after 16 weeks, will continue to improve if retreatment is deferred. METHODS This is a prospective, multicenter, observational, single-...
