Electrodiagnostic evaluation consists of Nerve Conduction Studies (NCSs) and needle Electromyography (EMG), is an essential component of clinical practice. It provides both valuable quantitative and qualitative insight into neuromuscular function which aid to diagnosis. Sometimes it differentiate between closely mimic disease which cannot be ensured by clinical signs and traditional investigations. Though it is an important tool but very few studies is noticed which revealed the pattern of disease based on NCS and EMG.Therefore, the current study aimed to evaluate the pattern of disease profile based on electrophysiological study in an electro-diagnostic lab in a tertiary care hospital. Methods: This hospital based descriptive cross-sectional study was conducted at the Electrodiagnostic Lab in the department of Neurology in Dhaka Medical College Hospital, for six months period following approval of this protocol. People who were attending in electro-diagnostic lab for performing electrophysiological studies due to any reason were approached for inclusion of the study. Informed written consent were taken from each patients. Detailed history and clinical examination were taken from each participants. Moreover, the findings of neurophysiological reports were included into the data collection form. After collection, data were edited manually and prepared for data entry and analysis weredone by using SPSS 23. Results: Among 100 patients, 55% were males and 45% were females. Mean age was 44.97±13.39 years and prevalent (34%) age group 41-50 years. About 42% lived in urban areas and 58% were in rural area.Among all, 31% had their disease for 2-6 months, 18% had for 7-12 months, another 18% had <1month and 15% participants had disease for >1year. About 63% were diagnosed as peripheral neuropathy, 8% had muscle disease, 12% had other diseases and 17% patients had normal neurophysiologic study.NCS findings revealed that 26% cases had Peripheral nerve entrapment and 28% cases had Polyneuropathy. Among the Peripheral nerve entrapment, Carpal tunnel syndrome was the most common diagnosis (20%), and GBS is the most common among polyneuropathy cases. During EMG, total 8 patients were found to have muscle disease. Six patients had muscle disease and 2 patients had neuromuscular junction disorder. Conclusion: This finding provides a pattern of diagnosis of an electro diagnostic lab. However, larger study is needed to get the actual prevalence of disease.
