title: [The study of afferentation in arthrogryposis].
abstract: The electroneurograms of the tibial and median nerve in children with arthrogryposis have been performed; excitability curves which characterizes the function of the nerves were recorded. Afferent conduction velocity in 30 examined nerves showed statistically significant slowing down. An amplitude of evoked potentials in the tibial and median nerves was decreased but the difference compared to the control group was not statistically significant. Histograms based on electroneurography indicate existence of two groups of results, that might reflect neurogenic and/or myogenic origin of arthrogryposis. Excitability curve has been moved upwards and to the right in one point only, characterizing the tibial nerve function; in 5 remaining points the differences with controls were not significant. All-over results indicate subclinical afferentation impairment within lower extremities in children with arthrogryposis.
