β-modulation range during the proprioceptive feedback condition. Modulation range for five healthy subjects (single blue dots and group results as boxplot) and for two stroke patients (black and red dots). This measure reflects the individual ability to modulate sensorimotor β-oscillations captured with the feedback electrodes. The β-modulation range is defined in the individual frequency bin of the event-related spectral perturbation (ERSP) with the largest difference between the motor imagery (MI) epoch (the minimum) and in the rest epoch (the maximum).
