Tremendous advances in neuroimaging methods and analytic techniques hold great promise in providing the rehabilitation clinician with a much greater understanding of brain pathology and its potential influence on rehabilitation outcome. This special issues of NeuroRehabilitation overviews the field. Contemporary neuroimaging methods are reviewed specifically in traumatic brain injury (TBI), anoxic brain injury (ABI) and stroke. Innovative methods combined with standard quantitative metrics and traditional clinical assessment provide the rehabilitation clinician with multiple methods to best understand the nature and extent on underlying neuropathology and how to use this information in guiding rehabilitation therapies and predicting outcome.

Case ReportsRecovery of assisted overground stepping in a patient with chronic motor complete spinal cord injury: a case report.
Clinical studies have shown that after incomplete spinal cord lesions at the thoracic level, patients can develop functional gait patterns through gait training. To date, however, training has been ineffective in producing gait in patients with clinically motor complete spinal cord lesions. ⋯ Even after a motor complete lesion with some preservation of sensory pathways, the spinal cord may be able to retain some of its locomotor function through intensive gait rehabilitation.

Relationship between the modified Rankin Scale and the Barthel Index in the process of functional recovery after stroke.
The modified Rankin Scale (mRS) and the Barthel Index (BI) are the most common clinimetrical instruments for measuring disability after stroke. This study investigated the relationship between the BI and the mRS at multiple time points after stroke. The BI, which is a widely used instrument for longitudinal follow-up post-stroke, was used as reference to determine the effect of time on the sensitivity of the mRS in differentiating functional recovery. ⋯ Maximum sensitivity of mRS in differentiating functional recovery is reached at six months post-stroke.

Detection of hemorrhagic and axonal pathology in mild traumatic brain injury using advanced MRI: implications for neurorehabilitation.
There is a need to more accurately diagnose milder traumatic brain injuries with increasing awareness of the high prevalence in both military and civilian populations. Magnetic resonance imaging methods may be capable of detecting a number of the pathoanatomical and pathophysiological consequences of focal and diffuse traumatic brain injury. Susceptibility-weighted imaging (SWI) detects heme iron and reveals even small venous microhemorrhages occurring in diffuse vascular injury. Diffusion tensor imaging (DTI) reveals axonal injury by detecting alterations in water flow in and around injured axons. The overarching hypothesis of this paper is that newer, advanced MR imaging generates sensitive biomarkers of regional brain injury which allows for correlation with clinical signs and symptoms. ⋯ Animal data gave important tissue correlations with imaging results. SWI and DTI are commercially available sequences that can improve the diagnostic and prognostic ability of the trauma clinician. These biomarkers of regional brain injury which are present in imaging shortly after acute injury and persist indefinitely can inform clinicians and researchers about not only injury severity but also which neurobehavioral systems were injured. Analogous to stroke rehabilitation, having an understanding of the distribution of brain injury should ultimately allow for development of more effective rehabilitation strategies and more efficient clinical interventional trials.
