Nerve fibre velocity and refractory period distributions in nerve trunks.
With the use of a double stimulus technique, nerve fibre velocity range measurements were performed over a single conduction distance in 13 normal subjects and over two conduction distances in another 12 normal subjects. The velocity ranges were found to be dependent upon the conduction distance, owing to unknown refractory period delays. Refractory period values were calculated for the 12 subj...
متن کاملSolitary tumours of peripheral nerve trunks.
Primary solitary tumours of the peripheral nerve trunks are relatively infrequent. Three such tumours have been treated at Hammersmith Hospital during the last four years, but a search of the hospital records for the period 1939-1950 has not shown any similar cases. (Solitary tumours of the auditory nerve and spinal nerve roots are not included in this report.) In these three patients the tumou...
متن کاملDecompression of peripheral nerve trunks in leprosy to prevent the development and progression of deformities
Peripheral nerve involvement results in deformities formation in leprosy. High doses of (40-60 mg) steroids along with the anti-leprosy drugs is preferred even though the 70-75% cases develop deformity with the above treatment. 772 ulnar nerves, 120 median nerves and 108 posterior tibial nerves not responding to above medical treatment in 12 weeks, were undertaken for external and internal nerv...
متن کاملUsing Eggshell Membrane as Nerve Guide Channels in Peripheral Nerve Regeneration
Objective(s): The aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (ESM) tube conduit in comparison with autograft. Materials and Methods: Thirty adult male rats (250-300 g) were randomized into (1) ESM conduit, (2) autograft, and (3) sham surgery groups. The eggs submerged in 5% acetic acid. The decalcifying membranes were cut into four pie...
متن کاملMapping of Small Nerve Trunks and Branches Using Adaptive Flexible Electrodes
Selective stimulation is delivered to the sciatic nerve using different paris of contacts on a split-ring electrode, while simulatneous recordings are acquired by the neural ribbon electrodes on three different branches. Two hook electrodes are also implanted in the muscle to monitor the activated muscle responses. It shows that the high precision implantation of electrodes, increases the effic...
