Tremoranalysis by ultrasound



Tremoranalysis by ultrasound



Aktuelle Neurologie 30(3): 131-135, April



Tremor is an often disabling socially stigmatizing and therefore isolating symptom of very different origins. It is treated after a classification which mainly depends on its frequency. Measuring of frequency can be done by EMG (polymyography) or accelerometry. Both methods are time-consuming labor tests. We describe a simple bedside method for measuring visible, unvisible or latent tremors frequency and amplitude with ultrasound. Our experiences and some examples are described. Sensitivity and specifity of ultrasound is comparable to EMG and accelerometry, but is in contrast easily and quickly done. It provides exact data of an important and still not completely understood phenomenon, which usually is estimated only by eye.
