The vast majority of dogs with cervical disk herniation experience cervical pain and only mild motor deficits; therefore, not much is known about the factors that predict recovery in dogs with nonambulatory tetraparesis (NAT) secondary to cervical disk herniation. In this retrospective study, we tested the hypothesis that two previously reported prognostic factors, site of disk herniation and s...

To build an understanding of the neurobiology underpinning arm recovery in people with severe arm impairment due to stroke, we conducted a pooled individual data systematic review to: 1) characterize brain biomarkers; 2) determine relationship(s) between biomarkers and motor outcome; and 3) establish relationship(s) between biomarkers and motor recovery. Three electronic databases were searched...

BACKGROUND The study aims to assess the therapeutic benefits of motor imagery training in stroke patients with persistent motor weakness. There is evidence to suggest that mental rehearsal of movement can produce effects normally attributed to practising the actual movements. Imagining hand movements could stimulate the redistribution of brain activity, which accompanies recovery of hand functi...

The primary focus of rehabilitation for individuals with loss of upper limb movement as a result of acquired brain injury is the relearning of specific motor skills and daily tasks. This relearning is essential because the loss of upper limb movement often results in a reduced quality of life. Although rehabilitation strives to take advantage of neuroplastic processes during recovery, results o...

The relationship of the structural integrity of white matter tracts and cortical activity to motor functional outcomes in stroke patients is of particular interest in understanding mechanisms of brain structural and functional changes while recovering from stroke. This study aims to probe these underlying mechanisms using diffusion tensor imaging (DTI) and fMRI measures. We examined the structu...

Greater loss in structural integrity of the ipsilesional corticospinal tract (CST) is associated with poorer motor outcome in patients with hemiparetic stroke. Animal models of stroke have demonstrated that structural remodeling of white matter in the ipsilesional and contralesional hemispheres is associated with improved motor recovery. Accordingly, motor recovery in patients with stroke may r...

Previous studies on the mechanisms of motor recovery in patients with middle cerebral artery (MCA) infarct except for the studies on cortical peri-infarct reorganization after primary motor cortex infarct were reviewed. Eight studies were classified and reviewed by the following four motor recovery mechanisms: contribution of premotor cortex, subcortical peri-infarct reorganization, ipsilateral...

BACKGROUND AND PURPOSE The purpose of this study was to assess the effects of stroke involvement of primary and secondary hemispheric motor systems and corticofugal tracts on arm and hand recovery. METHODS Forty-one patients participating in an inpatient stroke rehabilitation database, admitted 17+/-2 (SEM) days after initial unilateral hemispheric ischemic stroke, with neuroimaging studies p...

Abstract—Among the therapeutic strategies under study to improve long-term outcome after stroke are drugs targeting events that underlie recovery. Drugs that enhance recovery are separate from those that promote neuroprotection or reperfusion in patients with stroke. Recovery-based drugs have distinct therapeutic targets that are related to plasticity and growth after stroke, and in general, im...
