Influence of Pacing by Periodic Auditory Stimuli on Movement Continuation: Comparison with Self-regulated Periodic Movement.

Ito M, Kado N, Suzuki T, Ando H - J Phys Ther Sci (2013)

Bottom Line: Inter-onset intervals were 1,000, 2,000 and 5,000 ms.For the 1,000 and 5,000 ms tasks, there were significant differences in the mean inter-tap interval following auditory pacing compared with self-pacing.However, the consistency of periodic movement is mainly dependent on the inherent skill of the individual; thus, improvement of consistency based on pacing is unlikely.

ABSTRACT
[Purpose] The purpose of this study was to investigate the influence of external pacing with periodic auditory stimuli on the control of periodic movement. [Subjects and Methods] Eighteen healthy subjects performed self-paced, synchronization-continuation, and syncopation-continuation tapping. Inter-onset intervals were 1,000, 2,000 and 5,000 ms. The variability of inter-tap intervals was compared between the different pacing conditions and between self-paced tapping and each continuation phase. [Results] There were no significant differences in the mean and standard deviation of the inter-tap interval between pacing conditions. For the 1,000 and 5,000 ms tasks, there were significant differences in the mean inter-tap interval following auditory pacing compared with self-pacing. For the 2,000 ms syncopation condition and 5,000 ms task, there were significant differences from self-pacing in the standard deviation of the inter-tap interval following auditory pacing. [Conclusion] These results suggest that the accuracy of periodic movement with intervals of 1,000 and 5,000 ms can be improved by the use of auditory pacing. However, the consistency of periodic movement is mainly dependent on the inherent skill of the individual; thus, improvement of consistency based on pacing is unlikely.

Mentions: The ITI series of tasks 2 and 3 are shown in Fig.2. During the pacing phase, the ITI series of most subjects were close to thetarget duration; as the duration of the IOI increased, several subjects developed a wavy ITIseries. During the continuation phases using an IOI of 1,000 ms, one subject tended torespond with intervals longer than 1,000 ms. With an IOI of 2,000 and 5,000 ms, drifts fromthe target interval increased compared to that of the 1,000 ms IOI; this difference was moremarked for the syncopation condition.
