The development of rhythm regularity, neuromuscular strategies, and movement smoothness during repetitive reaching in typically developing children

INTRODUCTION: This study examined the development of paced coordinated reaching characterized by the successful entrainment of the movement to an external pacer, synchronous muscle activations and movement smoothness. METHODS: Thirty children, 5-10 years of age, and ten adults were instructed to repeatedly reach for and move an object from a lower shelf to an upper shelf in time to a metronome. Surface electromyography data were recorded. …
