Focal conduction block in compression neuropathy of the proximal sciatic nerve.
Direct percutaneous stimulation of the proximal sciatic nerve with a high voltage electrical stimulator was given to a patient with acute sciatic compression neuropathy. Results clearly showed a focal conduction block at the sciatic notch, which could not be precisely localised and quantified by conventional electrodiagnostic methods.
متن کاملConduction block in acute motor axonal neuropathy.
Guillain-Barré syndrome is divided into two major subtypes, acute inflammatory demyelinating polyneuropathy and acute motor axonal neuropathy. The characteristic electrophysiological features of acute motor axonal neuropathy are reduced amplitude or absence of distal compound muscle action potentials indicating axonal degeneration. In contrast, autopsy study results show early nodal changes in ...
متن کاملProximal Sciatic Nerve Intraneural Ganglion Cyst
Intraneural ganglion cysts are nonneoplastic, mucinous cysts within the epineurium of peripheral nerves which usually involve the peroneal nerve at the knee. A 37-year-old female presented with progressive left buttock and posterior thigh pain. Magnetic resonance imaging revealed a sciatic nerve mass at the sacral notch which was subsequently revealed to be an intraneural ganglion cyst. An intr...
متن کاملFacial nerve conduction in diabetic neuropathy.
Diabetes mellitus (DM) has a severe influence on the nervous system and it is more likely to occur on the nerves of the upper and lower extremities than on the cranial nerves. According to the statistics, the incidence of cranial nerve involvement ranges anywhere from 3% to 14%. The aim of this study is to perform facial nerve conduction studies in diabetic patients with peripheral neuropathy, ...
متن کاملEntrapment of the proximal sciatic nerve by the hamstring tendons.
The purpose of this study was to evaluate the results of operative treatment of entrapment of the sciatic nerve by tight fibrous structures associated with the hamstring tendons close to their proximal insertion. We retrospectively evaluated the results of 22 operations performed in 16 patients (6 bilateral operations), on average six years postoperatively. There was complete relief in 11 cases...
