Abstract
This work presents the results of a controlled study with the aim to quantify the effect of emotional stress on physiologic tremor. A paced auditory addition test is utilized to induce emotional stress. The tremor is measured by means of a wearable activity sensor (GENEA), were empirical mode decomposition is used to extract the tremor signal. An autoregressive model and the fractal dimension of the signal are used to construct tremor features. The result of an ANOVA test provides evidence that the stress condition increases the tremor strength compared to the control. The observed changes of the spectral properties indicate that emotional stress affects intentional tremor. These findings support the usage of wearable activity sensors for the investigation of stress-related tremor changes and the evaluation of emotional context.
