How Can Creativity Transform the Way We Move?

A group of twenty‑four professional dancers tested the link between imagination and movement. Each dancer created two short choreographies: one inspired by a mental image, the other by a narrated story. To record the motions, an inertial sensor—a tiny box that captures every body displacement—was used. The data revealed that when dancers were guided by a narrative, they took more risks, stretched their gestures, and occupied more space than when they followed an image. In practice, the story pushed the body to explore new directions, move with greater breadth, and try bolder moves. This result suggests that creativity is not just an idea in the head, but can concretely change how we move. Moreover, inertial technology proved useful for measuring not only speed or acceleration, but also the artistic nuances of a performance. In the future, such sensors could help choreographers better understand how different sources of inspiration affect the body, opening new paths for dance and human‑movement research.

The study falls within the field of neurocognition of movement, where episodic representations—visual or narrative—are considered mental models that guide motor execution. The inertial sensors used (3‑axis accelerometers and gyroscopes) recorded data at 100 Hz, allowing a three‑dimensional reconstruction of body segments. Analysis employed motor variability metrics such as movement amplitude (range of motion), movement volume (space occupied), and risk‑taking index (deviation from the expected trajectory). Results show a significant statistical difference (p < 0.01) between the two conditions, with narrative increasing all cited parameters. From a neurophysiological perspective, narrative activates a broader cortical network, including the dorsolateral prefrontal cortex and precuneus, regions linked to complex mental scenario generation and motor planning. This broader involvement may explain the observed increase in expressive freedom. Moreover, inertial technology proved sensitive to subtle changes in body dynamics, surpassing traditional optical‑marker methods, especially in uncontrolled environments. Practical implications include real‑time feedback for choreographers and therapists, enabling modulation of creativity through targeted cognitive stimuli. In summary, the research highlights how creativity, mediated by different mental representations, can reshape motor structure, opening new avenues for rehabilitation, artistic training, and understanding of cognitive‑motor processes.
