EFFECT OF AGE, GENDER AND BODY MASS INDEX ON TIBIAL AND PERONEAL MOTOR NERVE CONDUCTION STUDY VARIABLES

Introduction: Different variables of Nerve Conduction Study (NCS) show changes to different extent in various pathological states. However, certain physiological factors may affect them too. Aims and objectives: This cross sectional study aimed to evaluate the role of age, gender and BMI upon these variables in the tibial and peroneal nerves. Materials and methods: 51 healthy subjects were chosen according to exclusion and inclusion criteria. Reference limits were derived from the obtained data as Mean±2SD. p<0.05 was considered statistically significant. The Degree of Coefficient of Correlation was graded into low (0.29 ≥ absolute value r ≥ 0.1), moderate (0.49 ≥ absolute value r ≥ 0.3) and substantial (absolute value of r ≥ 0.5). Results: No sex-wise correlation was seen with the NCS Parameters of Tibial and Peroneal Nerves, whereas age showed deteriorating correlation (p value <0.05). Also, no substantial correlation was seen, except between Height and Weight of the subject, with the Distal Motor Latency of the Peroneal Nerve.
