Mobile (cellular) phone use and driving: a critical review of research methodology.

Studies have examined possible effects of concurrent mobile phone use on driving performance. Although interference is often apparent, determining the implications of such findings for 'real world' driving is problematic. This paper considers some relevant methodological issues including the definition of procedures and terms, operationalization of task elements, sampling of task components, and the provision of experimental controls.

Spastic hemiplegia in a quadriplegic patient: treatment with phenol nerve block.

A quadriplegic patient with a C6 lesion had a stroke with aphasia and right hemiplegia 20 years after his cervical cord injury. The combination of hemiplegia and quadriplegia created unusual rehabilitation problems, the most disabling of which was a painful flexion contracture of the right elbow that prevented any useful right arm function. A sequence of phenol nerve blocks produced almost complete resolution of this contracture and was a key factor in his successful return to independent living.
