Study of correlation of demographic and anthropometric parameters with nerve conduction velocity in upper limb

Abstract

Introduction: Nerve conduction studies (NCS) are primarily used to identify peripheral nervous system problems. Numerous anthropological and physiological factors influence nerve conduction velocity. Setting absolute criteria without accounting for these factors is said to produce false positive and false negative findings. The purpose of the current study was to evaluate how height affects nerve conduction velocity, particularly in relation to median nerve fibres in the Indian population.

Materials and Methods: In present cross-sectional prospective study 60 individuals of both sexes from all age group who voluntarily participated in study were enrolled. After obtaining demographic & anthropometric details in each participant, all were assessed for nerve conduction velocity of median motor & sensory nerve in both hands.

Observations and Results: Maximum cases i.e. 49 (81 %) amongst total participants were from age group 31 to 60 years. Males were 47 (78 %) & females were 13 (22 %). As the height increased descending trend was found in NCV values in motor fibres in both hands whereas ascending trend was observed in sensory fibres values.

Conclusion: To conclude, as baseline nerve conduction measurements are dependent on anthropometric factors, it is important to understand the effect of these various factors on the normal values for nerve conduction measurements to aid in identifying abnormal nerve conduction study results.
