ABSTRACT: After 300 - 500 ms
of various movements, a significant rebound in beta rhythm power is observed.
This phenomenon is called Post-Movement Beta Rebound (PMBR). Previous studies
have been carried out in a single movement context in the exploration of its
functional significance, and few studies have been conducted in connected
movements. Therefore, this study used the cue-induced delayed task paradigm to
examine the PMBR change in the motor cortex of the 20 adults when they were moving under the single or connected movements condition. It was found on
right-hand movements that the PMBR of the first movement in a connected
condition was stronger than that of a single movement, and it was also observed
on both left- and right-hand movements that the PMBR of the first movement was
stronger than that of the last movement in a connected condition. The results
show that the PMBR after the connected movement was stronger than the no
movement connection, reflecting that PMBR plays an important role in the
preparation of subsequent movements.
