Signal Processing

Abstract

As summarized in the previous chapter, many instruments have been developed to measure tremor using a variety of technologies. These instruments include accelerometers, gyroscopes, magnetometers, audio, video, tablets, lasers, motion capture systems, electromyograms, electromagnetic systems, microelectrode recordings, local field potentials, and many others. Each of these instruments produces one or more continuous signals that are obtained from one or more points in or on the body. No instrument has become accepted as a gold standard for quantifying tremor. All instruments have some disadvantages, and new instruments are continuing to be developed.
