Examinations of the motor conduction time between the motor cortex and the Erb point in patients suffering from tumors of the central nervous system.
The cortical latency and the motor conduction time between the motor cortex and the Erb point were investigated in 85 patients with intracranial and in 9 patients with space-occupying spinal tumors. Electrophysiological examinations revealed pathological changes in 19% of intracranial events, and in 100% of cases of spinal tumors. In these latter cases close correlation was registered between the motor evoked potentials and the clinical symptoms of the patients.
