Multi Motor Unit Analysis


Sanjeev Nandedkar, Ph.D.

With over 30 years of experience, Sanjeev is an award winning author, editor and reviewer, researcher, instrument design engineer, teacher, and clinical expert in the EMG field. He has delivered lectures, workshops and seminars in over 25 countries at universities, hospitals and EMG conferences. As an editor, Sanjeev started the “EMG on DVD” series. In collaboration with other clinicians, he developed Motor Unit Number Index (MUNIX) along with Multi-motor unit Analysis (MMA) and Turns & Amplitude (TA) methods available on Natus EMG systems. His primary research interest is in Automatic analysis of EMG signals, Modeling EMG signals and Technical aspects of EMG waveforms. Sanjeev is currently a Senior Consultant at Natus Neuro.

The needle EMG examination is usually performed using visual assessment of signals on the display and their sound on an audio monitor. Quantitative analysis of motor unit potentials (MUPs) is considered useful, but very time consuming. The Multi-MUP analysis (MMA) is a computer aided method of MUP analysis that can allow recording 20+ MUPs in less than 5 minutes. In this webinar, we will discuss the basic principles of MUP analysis and measurements. The MMA algorithm will be described with emphasis on entry of reference values and review of results.

Intended Audience:
DPs, technical and clinical support specialists, end-users, researchers. The method is available on all brands of Natus systems.
