Comparable neural and behavioural performance in dominant and non-dominant hands during grasping tasks.

ABSTRACT: Hand dominance has long been associated with differences in neural control and motor performance, with the dominant hand typically exhibiting better coordination in reaching tasks. However, the extent to which this dominance influences performance in finger force control remains unclear. This study aimed to examine the behavioural and neural features of the dominant and non-dominant hands during grasping and lifting tasks in healthy young adults, focusing on the synergy index, EEG band power, and EEG-EMG coherence as key measures. Twenty right-handed adults participated in this study. Participants engaged in an experimental task where they grasped a handle for the initial 5 s, followed by lifting and holding it for an additional 5 s. There were two task conditions: fixed (thumb platform se
