Background: Needle electromyography (EMG) is the study of electrical activity of muscle¹. It localizes lesion, either to nerve, muscle or neuromuscular junction. We aimed to obtain a preliminary normative EMG data for our local population.

Methods: We investigated twenty (m=10, f=10) healthy adults of age 17–50 years using convenient sampling and based on inclusion and exclusion criteria. Digital Nihon Kohden machine (NM–420S, H636, Japan) and needle electrodes were used to evaluate six muscles in all limbs. Anthropometric, motor unit action potential (MUAP) amplitude and MUAP duration recorded were analyzed using descriptive statistics.

Results: The mean duration of APB, ADM, FDI, EDC, TA, and EDB were 6.24±1.71, 5.9±1.6, 6.20±1.71, 7.9±1.73, 10.82±1.81, and 9.12±1.98 ms respectively.

Conclusion: Similar differences in normative values have been reported. This study provided a preliminary normative data for our local population, so that the inferences made on further are objective and valid.
