Comparative Study Clinical TrialAn electroencephalographic study of imagined movement.
Determine the generator sources for actual and imagined (simulated) movements of fingers and toes. ⋯ (1) The motor networks underlying the generation of actual and imagined movements are different. (2) Imagined movements lack a primary motor area source, but involve medial and ipsilateral structures. (3) The effectiveness of imagined movements in rehabilitation may stem from activation of premotor or supplementary motor areas.

Implanted functional electrical stimulation hand system in adolescents with spinal injuries: an evaluation.
To study the utility and functional benefits of an implanted functional electrical stimulation (FES) system for hand grasp and release in adolescents with tetraplegia secondary to spinal cord injuries. ⋯ For five adolescents with tetraplegia, the combination of FES and surgical reconstruction provided active palmar and lateral grasp and release. Laboratory-based assessments demonstrated that the FES system increased pinch force, improved the manipulation of objects, and typically increased independence in six standard ADL as compared to pre-FES hand function. The study also showed that the five adolescents generally preferred FES for most of the ADL tested. Data on the benefits of the implanted FES hand system outside of the laboratory are needed to understand the full potential of FES.

Case ReportsAcute low back pain secondary to retroperitoneal hemorrhage in an elderly man.
Acute low back pain is a common complaint heard in the emergency room and in a physiatrist's practice. It is important to rule out occult pathology in patients with an atypical presentation. In the case presented here, the patient was elderly, developed back pain without preceding trauma or lifting, had a history of easy bruisability, had a large ecchymosis, and had worsening back pain with bedrest. ⋯ He was diagnosed with acquired hemophilia secondary to factor VIII inhibitors. This has implications for physicians who treat patients with acute low back pain. They must be alert to potentially life-threatening causes of low back pain.
