Case Reports
Hardware failure and spinal pseudoarthrosis causing autonomic dysreflexia: a report of two cases.
Case report. ⋯ Owing to the failure of spine-stabilizing hardware, sitting upright may cause an afferent stimulus that triggers the onset and worsening of symptoms associated with autonomic dysreflexia. Therefore, in contrast to current acute treatment regimes, lying down may be preferred to sitting upright (to decrease blood pressure) as a means to relieve the afferent stimulus. Surgical correction and hardware replacement alleviated the symptoms in these two patients.

Case Reports
Control of a neuroprosthesis for grasping using off-line classification of electrocorticographic signals: case study.
Proof of concept study to control a neuroprosthesis for grasping using identification of arm movements from ECoG signals. ⋯ The feasibility of using ECoG signals as a control strategy for a neuroprosthesis for grasping was shown.

Case Reports
Traumatic spinal-cord herniation associated with pseudomeningocele after lower-thoracic nerve-root avulsion.
Traumatic spinal-cord herniation after nerve root avulsion is rare. We report on the first patient with spinal-cord herniation associated with pseudomeningocele in the lower conus medullaris region after nerve avulsion. ⋯ This is the first report of spinal cord herniation after nerve root avulsion in the conus medullaris region. CISS imaging is highly useful for the demonstration of spinal cord herniation, syringomyelia and pseudomeningocele. To restore neurological function in patients with progressive symptoms, we recommend surgical treatment.
