Disease relevance of Ulnar Nerve


High impact information on Ulnar Nerve

  • The motor neurones that lie in the dorsolateral columns of spinal segments C7 and C8 and supply the flexor muscles of the forepaw were axotomized by cutting and removing part of the median and ulnar nerves above the elbow [6].
  • Aminoguanidine (but not aspirin) inhibited a diabetes-induced defect in ulnar nerve conduction velocity, but neither agent was found to influence kidney structure or albumen excretion [7].
  • We compared the amplitude of spinal N13, brainstem P14, parietal N20 and P27 and frontal N30 SEPs obtained by stimulating the median and ulnar nerves simultaneously (MU), the amplitude value being obtained from the arithmetic sum of the SEPs elicited by stimulating the same nerves separately (M + U) [8].
  • Amplitudes of spinal N13 and brainstem P14 potentials following stimulation of the ulnar nerve ipsilateral to the deafferented median nerve were greater than those following stimulation of the contralateral ulnar nerve [9].
  • Changes in synaptic strength and unmasking inputs secondary to disconnection of the normally dominant inputs to the 'median nerve' cortex may be the mechanisms underlying ulnar nerve SEP changes [9].

Associations of Ulnar Nerve with chemical compounds

  • Tungsten microelectrodes were inserted percutaneously into motor fascicles of the ulnar nerve of 5 subjects, which was then blocked distally with local anaesthetic [24].
  • On the other occasion, adductor pollicis twitch force was measured during transcutaneous supramaximal ulnar nerve stimulation and arterialized venous blood gas determinations were obtained before, during, and after CO2 breathing [25].
  • METHODS: Train-of-four stimulation was applied every 12 s to both ulnar nerves and adductor pollicis twitch tension was measured in anesthetized participants given 30 micrograms/kg vecuronium [26].
  • While monitoring the thenar EMG response to ulnar nerve stimulation, the authors gave either 105, 150, 210, or 300 micrograms/kg of atracurium to 60 patients [27].
  • After inhalational induction of anesthesia and tracheal intubation, MAC was determined in each patient by observing the motor response to a 10-s, 50-Hz, 80-mA transcutaneous electric tetanic stimulus to the ulnar nerve at varying concentrations of either halothane or enflurane [28].

Gene context of Ulnar Nerve

  • METHODS: First dorsal interosseous twitch and tetanic contractions evoked by single and 10-Hz ulnar nerve stimulation were recorded with a force transducer in 15 patients with genetically confirmed DM1 and 15 control subjects [29].
  • The purpose of this study was to examine whether the use of tactile assessment of the response of the adductor pollicis to supramaximal TOF stimulation of the ulnar nerve at the wrist during anaesthesia affected the incidence of PORC [30].
  • Polygraphic electromyograph recordings in patients with entrapment of the ulnar nerve at the elbow have demonstrated long-duration bursts of co-contraction in antagonistic muscles, similar to those observed in focal dystonia [31].
  • CONCLUSION: Carpal tunnel syndrome can be distinguished from hand-arm vibration syndrome if all factors--anatomical, associated physiological and medical conditions, work exposure history, and ulnar nerve involvement--are evaluated [32].
  • Percutaneous, supramaximal twitch stimulation of the median and ulnar nerves was used in combination with temporary ischaemia of the forearm to characterize the summed ATPase activity [33].
