BACKGROUNDF wave is an important electrodiagnostic parameter which assesses conduction through both proximal and distal segments of nerve. It may vary between different population due to difference in physiological variables like height, arm length and temperature. So a normative reference data is to be created for using this parameter with sensitivity and specificity and to improve the diagnostic capacity. AIMAim of this study was to derive normal reference value for F wave minimal latency in healthy people in Malabar region and to find out the effect of height on F wave minimal latency.Financial or Other, Competing Interest: None.
