Aim: To study and analyze the fasciculations in multiple sites clinically, by EMG and by ultrasound. Find the usefulness of neuro ultrasound in identifying fasiculations both occult and manifest. Materials and Methods : Patients who are admitted with fasciculations with neurological illness in RGGGH. Patients with age group between 18yrs to 70 yrs. Totally 30 patients were examined. The duration of study was between December 2012 to Decmber 2013 Assessment by detailed history, neurological examination by standard proforma and criteria, EMG by standardized protocol (AAN), ultrasound examination of muscle using transducer of 7.5 MHZ for 30 seconds in multiple sites were studied. Correlation of EMG, Ultrasound and clinical examination were done Results and observation : In our study of 30 patients EMG was compared with ultrasonography in the detection of fasciculations. The correlation coefficient between EMG and USG was 0.024.High degree of correlation was found between the EMG detection of fasciculations and Ultrasound detection of fasciculations which was statistically significant with a p value of <0.005. USG detected more percent of fasciculations when compared to EMG. USG is noninvasive and fasciculation can be easily detected. USG can detect occult fasciculation which is difficult to detect by EMG. Different examination by EMG to search for occult fasciculations is difficult since patient may experience pain and technically difficult. But USG can be judiciously used to detect occult fasciculations. Conclusion : Neuromuscular ultrasound is a useful technique in neurology especially in confirmation of fasciculations in both clinical and subclinical. The utility of neuromuscular ultrasound in detecting occult fasciculations enables diagnostic accuracy of anterior horn cell disease. It is comparable to needle EMG in detecting fasciculations . Neuromuscular ultrasound is a non invasive, painless tool in the evaluation of fasciculations.
