Activation of sensorimotor integration processes with a brain-computer interface

A BCI-controlled hand exoskeleton activates neuroplasticity mechanisms, promoting motor learning. The contribution of perception to this phenomenon is understudied. aim study was assess the impact sensorimotor integration on effectiveness neurorehabilitation based learning a opening movement by stroke patients using BCI and investigate effect ideomotor training spasticity in paretic hand. conducted 58 (median age: 63 (22; 83) years) with traumatic brain injury, ischemic (76%) or hemorrhagic (24%) preceding 2 (1.0; 12.0) months. received 15 (12; 21) sessions BMI-controlled exoskeleton. Hand function assessed before after rehabilitation Fugl–Meyer, ARAT, Frenchay, FIM, Rivermead, Ashworth scales. An increase muscle strength observed 40% during flexion extension radiocarpal joint 29% abduction adduction joint. Muscle simultaneously increased (p < 0.004). Ideomotor ineffective for reducing because no statistically significant reduction tone detected. Improved performance positively correlated improvements daily activities. Motor robotic orthosis kinesthetic receptors, restores sensation improves fine skills through better integration.
