Functional recovery following experimental nerve injury has been notoriously difficult to quantify precisely. The current gold standard in the rat sciatic nerve model involves analysis of footprints of the recovering animal, and computation of the sciatic function index (SFI). We performed transection injuries and measured recovery both by walking track analysis and by a newer, simpler, more qu...
OBJECTIVES The evolutionary pattern of spontaneous recovery from acute neglect was studied by assessing cognitive deficits and motor impairments. Detailed lesion reconstruction was also performed to correlate the presence of and recovery from neglect to neural substrates. METHODS A consecutive series of right brain-damaged (RBD) patients with and without neglect underwent weekly tests in the ...
Research documents that African American and Latinos who have experienced an acute stroke recover more slowly than Caucasians in the United States. This descriptive study examines (1) the variation in Caucasian, Puerto Rican, and African American motor function after stroke; (2) the association between caregiver attributes and motor recovery after stroke; and (3) the degree to which caregiver a...
We determined whether rehabilitation after cortical injury also drives dynamic dendritic and spine changes in functionally distinct subsets of neurons, resulting in functional recovery. Moreover, given known requirements for cholinergic systems in mediating complex forms of cortical plasticity, including skilled motor learning, we hypothesized that cholinergic systems are essential mediators of...
Partial injury to the corticospinal tract (CST) causes sprouting of intact axons at their targets, and this sprouting correlates with functional improvement. Electrical stimulation of motor cortex augments sprouting of intact CST axons and promotes functional recovery when applied soon after injury. We hypothesized that electrical stimulation of motor cortex in the intact hemisphere after chron...
[Purpose] Post-stroke motor recovery consists of both true recovery and compensatory movements. Although compensatory movements are learned more quickly early after stroke, the role of compensatory movement patterns in functional recovery is controversial. We investigated the role of compensatory movement patterns in the long-term functional motor recovery after stroke. [Subjects and Methods] M...
BACKGROUND Although the consequences of spinal cord injury (SCI) within the spinal cord and peripheral nervous system have been studied extensively, the influence of SCI on supraspinal structures during recovery remains largely unexplored. OBJECTIVE To assess temporal changes in cortical sensorimotor representations beginning in the subacute phase following SCI and determine if an association...
UNLABELLED Sectioned facial nerves can be repaired with grafting or end-to-end anastomosis. OBJECTIVE To discuss these repair procedures and what can be expected of them. METHOD Seven patients with sectioned facial nerves were included in the study. Four underwent grafting and three were offered end-to-end anastomosis. Facial nerve palsy was iatrogenic in five patients and was caused by bul...
