The aim of this study is to generate normative database of nerve conduction parameters (NCP) for the common peroneal nerve (CPN) from the tibialis anterior (TA) muscle. A total of 70 healthy male and female subjects, 13-66 years of age, without risk factor for neuropathy were tested. Digital NCV/EMG machine was used to analyze the components of compound motor action potential (CMAP) that are amplitude, distal latency (DL), and conduction velocity (CV). Study was performed at 320C room temperature. Limb Temperature was controlled by hot water bag when needed.  The CPN Motor studies gave DL of 3.01 ms, Amplitude of 3.84 mv and CV of 56.26 m/sec from TA.  In our study, no significant difference was seen in NCP between right and left sides, Moreover, no correlation was observed between age and NCP. This study will be helpful for our locality in establishing normative database of NCP of common peroneal nerve while recording from TA. Minimum and maximum of normal were obtained, and 25%, 50% and 75% percentile were calculated. For proposing normative value, these measurements are suitable way for Electrophysiological evaluation of the Motor CPN, which can be used as reference by the other neurophysiology labs while dealing with this nerve.
