Sensory nerve action potentials in patients with peripheral nerve lesions.
In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...
متن کاملSensory transduction in peripheral nerve axons elicits ectopic action potentials.
Sensory properties of unmyelinated axons in the isolated rat sciatic nerve have been revealed previously by measuring stimulated neuropeptide release in response to noxious stimuli. In addition, axonal sensitization by inflammatory mediators has been demonstrated and shown to depend on the heat- and proton-activated ion channel transient receptor potential vanilloid receptor-1. It was unclear w...
متن کاملSensory conduction in medial plantar nerve: normal values, clinical applications, and a comparison with the sural and upper limb sensory nerve action potentials in peripheral neuropathy.
A method for recording the medial plantar sensory nerve action potential at the ankle with surface electrodes is described. Normal values in 69 control subjects are given and compared with the sural sensory nerve action potential in the same limb in the same subjects. Clinical applications were studied in 33 patients. The procedure may be applied in the diagnosis of L4-5 nerve plexus or root le...
متن کاملThe effects of axotomy on the conduction of action potentials in peripheral sensory and motor nerve fibres.
Medial gastrocnemius and sural nerves in one hindlimb of the cat were transected and prevented from regenerating. After periods ranging from 29-273 days, compound action potentials were recorded from axotomised and contralateral control nerves. The amplitude and integrated area of action potentials decreased and conduction velocity slowed following axotomy. The area under compound action potent...
متن کامل"amplitudes of sural and radial sensory nerve action potentials in orthodromic and antridromic studeis in children"
several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...
