Abstract :

Introduction: Smoking is the most common method of consuming tobacco which can lead to impairments in impulse conduction of sensory and motor nerves. Nerve conduction latency is an important parameter of sensory and motor nerve conduction studies. The present study was undertaken to assess nerve conduction latency in lower limbs in male smokers Objectives: To study nerve conduction latency in lower limbs in sensory (Sural) and motor (Peroneal) nerves in healthy male smokers and compå it with age, BMI matched non–smokers. Material and Methods: Study was carried out in 120 subjects belonging to age group 25–45 years. Sensory and motor nerve conduction latency was tested in Sural and Peroneal nerves respectively by standard method in apparently healthy male smokers, who were subdivided into mild, moderate and heavy smokers group (30 subjects/group) according to smoking index. Control group had 30 age & BMI matched non–smokers. Mean value of nerve conduction latency of different groups was compared statistically by one way Anova test and Bonferroni’s test. Results: The difference in mean values of nerve conduction latency (m/sec) in Sural (sensory) nerve of smokers was statistically significant among all the compared groups. The difference in mean values of nerve conduction latency (m/sec) in Peroneal (motor) nerve was statistically non–significant among all the compared groups. A significant correlation was observed between smoking index and Sural (sensory) nerve conduction latency. A non–significant correlation was observed between smoking index and peroneal nerve conduction latency. Conclusion: Smoking increases nerve conduction latency in sensory (Sural) nerve while it does not significantly affect nerve conduction latency in motor (Peroneal) nerve in lower limbs in apparently healthy smokers.
