Sural nerve conduction; Age related variation studies in our normal population.
Professional Med J Jan ;8(4):439-44.

Age related changes in nerve conduction studies are a well-established phenomenon. Few if any studies have been done in our population in this respect. Sural nerve conduction studies were carried out between June 1993 to May 1995. Eighty healthy individuals of all age groups, mean age 39.63 13.69 (range 17 to 75 years) who fulfilled the inclusion criteria was included in the study. Subjects included 51 males and 29 females with mean body mass index (EMI) 23.214.52 Kg/m2. The SNCV (Sural Nerve conduction velocity) and SNSAP (Sural nerve sensory action potentials) values of age group between 0-20 years in our population were 54.77 m/s and 14.65 V respectively as compared to 46.93.7 m/s and 18.4 6.4V correspondingly to western population. SNCV and SNSAP for age group between 21 and 40 years for our normal population was 51.21 m/s and 10.0 V respectively as compared to 46.2 3.7 m/s and 16.4 5.5 V for the western population. In the age group between 41 and 60 years of our population these values were 51.36 m/s and 6.79 V respectively vs. corresponding western values of 46.4 3.7 V and 13.6 7.5 V. Above 60 years SNCV and SN SAP was 48.19 m/s and 7.38 V among us whereas 45.5 3.1 m/s and 9.8 3.6 V in west. Our population seems to have higher conduction velocities but less potentials.
