Nerve conduction study (NCS) assesses peripheral nerve functions and is indicated in nerve or/and muscle disorders. This retrospective NCS done in Neurophysiology lab of BPKIHS, aimed to explore the pattern of neurological disorders, demographic and electrophysiological profile of patientsâ€™ referred for NCS. Demographic profiles, provisional clinical and electrophysiological diagnoses of 475 patientsâ€™ recorded from Nov 2006 to Aug 2010 were analyzed using descriptive statistics. Pearson’s Chi-squared test was used to find correlation between clinical and electrophysiological diagnoses. Age of the patientsâ€™ ranged from 2.5 to 88 (41.5Â±18.6) years. Middle age (36-60 years; n=203, 42.73%) group was the most commonly referred. Males (n=284, 59.8%) were referred more with tingling sensation (n=71, 17.88%) as the commonest complaint followed by weakness of extremities (n=64, 16.12%). Maximum cases were electro-diagnosed as neuropathy (n=314, 66.1%), chronic axonal type (n=169, 53.82%) being the most common followed by carpel tunnel syndrome. Mixed nerves (n=186, 60.8%) were most commonly involved followed by motor (n=74, 24.18%), and sensory nerves (n=46, 15.03%). A significant correlation (p< 0.01) was seen between clinical and electrophysiological diagnoses. This study showed different pattern of neurological disorders and confirmed the correlation of electrophysiological diagnoses with provisional clinical diagnoses.
