Chaotic properties of rhythmic forearm movement

Reveals the chaotic properties of voluntary single-arm and both-arm movements in various conditions of motion frequency and modes (single-arm mode, in-phase mode and anti-phase mode). Chaotic analyses of rhythmic forearm movements were performed, and it was confirmed that the chaotic characteristics represented by the correlation dimension and the largest Lyapunov exponents were included in the rhythmic forearm movements. Furthermore, it was clarified that there was a difference in the values of the Lyapunov exponents and the fractal dimensions between the right and left forearms, and consequently, the left forearm movement was more complex than the right forearm movement
