Energy spectrum obtained via the Fourier Transform of the left (affected) and right (unaffected) hand performing the task “pick up small objects and place in bin” of subject 1. It can be observed that the energy associated to the dominant frequency of the affected hand was much lower than that of the unaffected hand. We used both the dominant frequency and the energy associated to it as features. The SM parameter of the unaffected side was almost twice as high as that of the affected side.
