IMPACT OF ANTHROPMETRIC MEASURES ON SURAL NERVE CONDUCTION IN HEALTHY SUBJECTS
AbstractBackground: Nerve conduction studies are an invaluable aid to investigate and quantify thephysiological activity of peripheral nerves. These include measurement of sensory and motorconduction velocities and latencies of peripheral nerves. These nerve conduction parameters maybe affected by anthropometric factors like age, sex, height, weight and BMI. In this observationalstudy the impact of these anthropometric parameters was measured on sensory nerve conductionvelocity (SNCV) and sensory latency (SNSL) of sural nerve. Method: Sural nerve conductionstudies were conducted in EMG room of Neurology section of Medical Unit 1 at Sir Ganga RamHospital, Lahore on Electromyograph by Nihon Kohden MEB-5304K. Results: After followingstrict exclusion criteria by careful history and physical examination 25 normal healthy subjectsrecruited from local population by random sampling technique. The age range was 40-70 yearswith mean age 47.2±9.23 years. Gender distribution was 60% females and 40% males. The meanSNCV was found to be 53.16±5.68 meter per second (m/sec) and mean SNSL was 2.81±0.45milliseconds (msec). Conclusion: It was found that the mean sural nerve conduction velocity washigher and the mean sensory latency was shorter in healthy subjects than that of the Western races.Moreover, the SNCV decreases and SNSL increases significantly with age.Key words: Nerve conduction studies, sensory nerve conduction velocity (SNCV), sensorylatency, Sural nerve.
