Riassunto (Inglese)
Human movement is the result of cooperation between the brain, spinal cord and muscles. In particular, the spinal cord plays a central role in motor control through the activation of spinal motor neurons, which are responsible for muscle innervation. It is essential to understand the organization of spinal motor networks and their role in movement control.
In this thesis, spinal maps were reconstructed from EMG signals acquired from 22 healthy subjects under various motor conditions (stairs, ramps, treadmill and level ground). The signals were pre-processed, segmented on the gait cycle, and finally the spinal maps were reconstructed from an innervation matrix (Kendall map). The maps were then reconstructed in both normalized and non-normalized forms. The results show consistent patterns of spinal activation across the different tasks, with variation in intensity. Furthermore, the inter-subject analysis revealed good consistency compared to the average, despite some differences in motor strategy. These results suggest that spinal maps may represent a useful and robust tool for understanding motor control and supporting future applications in neuromodulation.
