Neurophysiological observations were made on normal subjects and on 57 patients who had had injuries to the spinal cord. The amplitude of the muscle compound action potential (M response) recorded from triceps surae in response to supramaximal stimulation of the tibial nerve was reduced in the patients indicating that there are changes in motor units below the level of a spinal lesion in man. I...

OBJECTIVE To evaluate the spasticity and electrophysiologic effects of applying extracorporeal shock wave therapy (ESWT) to the gastrocnemius by studying F wave and H-reflex. METHOD Ten healthy adults and 10 hemiplegic stroke patients with ankle plantarflexor spasticity received one session of ESWT on the medial head of the gastrocnemius. The modified Ashworth scale (MAS), tibial nerve conduc...

Purpose: To explore whether stimulation of C-fibers in tibial nerves can induce bladder inhibition by optogenetic transdermal illumination. Methods: Ten rats were injected with AAV2/6-hSyn-ChR2(H134R)-EYFP into the nerves. Transurethral cystometry was performed 4 weeks after virus injection. Illumination (473-nm blue light at 100 mW) fiber positioned above right hind paw near ankle. The transmi...

OBJECTIVE This study compared nerve regeneration in Wistar rats, using epineural neurorrhaphy with a gap of 1.0 mm and without a gap, both wrapped with jugular vein tubes. Motor neurons in the spinal cord between L3 and S1 were used for the count, marked by exposure of the tibial nerve to Fluoro-Gold (FG). METHOD The tibial nerves on both sides were cut and sutured, with a gap on one side and...

Electroneurography measures the speed of action potential after nerve stimulation. The aim this study was to evaluate motor conduction velocity in tibial surface stimulation healthy dogs, correlate obtained data by biological factors, and compare these results with published findings utilizing needle electrodes. performed 11 clinically dogs without anaesthesia. There were significant correlatio...

BACKGROUND Postoperative regional anesthesia hastens recovery and reduces the length of hospital stay of orthopedic surgical patients. This study was designed to assess the impact of pre-incisional continuous femoral block on postoperative conditions (POC) of tibial osteotomy and total knee arthroplasty patients. METHODS After insertion of a femoral catheter under peripheral nerve stimulation...
