“…Since proprioception originates from the activation of sensorimotor cortex [20], electroencephalogram (EEG) can also be used for proprioception analysis. In [21], the effects of ES on the senses of joint position and force were investigated, and significant coherence between proprioception and neural activities in the central nervous system was demonstrated using EEG power spectrum density (PSD) of bilateral sensorimotor cortex.…”

Objective. In recent years, the robot assisted (RA) rehabilitation training has been widely used to counteract defects of the manual one provided by physiotherapists. However, since the proprioception feedback provided by the robotic assistance or the manual methods is relatively weak for the paralyzed patients, their rehabilitation efficiency is still limited. In this study, a dynamic electrical stimulation (DES) based proprioception enhancement and the associated quantitative analysis methods have been proposed to overcome the limitation mentioned above. Approach. Firstly, the DES based proprioception enhancement method was proposed for the RA neural rehabilitation. In the method, the relationship between the surface electromyogram (sEMG) envelope of the specified muscle and the associated joint angles was constructed, and the electrical stimulation (ES) pulses for the certain joint angles were designed by consideration of the corresponding sEMG envelope, based on which the ES can be dynamically regulated during the rehabilitation training. Secondly, power spectral density, source estimation, and event-related desynchronization of electroencephalogram, were combinedly used to quantitatively analyze the proprioception from multiple perspectives, based on which more comprehensive and reliable analysis results can be obtained. Thirdly, four modes of rehabilitation training tasks, namely active, RA, DES-RA, and ES-only training, were designed for the comparison experiment and validation of the proposed DES based proprioception enhancement method. Main results. The results indicated that the activation of the sensorimotor cortex was significantly enhanced when the DES was added, and the cortex activation for the DES-RA training was similar to that for the active training. Meanwhile, relatively consistent results from the multiple perspectives were obtained, which validates the effectiveness and robustness of the proposed proprioception analysis method. Significance. The proposed methods have the potential to be applied in the practical rehabilitation training to improve the rehabilitation efficiency.

“…CKC is typically strong and can be detected in almost every individual ( Bourguignon et al, 2011. Both MEFs and CKC have an excellent inter-session reproducibility ( Mujunen et al, 2022 ;Piitulainen et al, 2018Piitulainen et al, , 2020. CKC strength is modulated by the degree of attention directed to the proprioceptive stimulus (Piitulainen et al, 2021), stimulus regularity, (Mujunen et al, 2021) extent (number of fingers) of stimulus and aging .…”

Proprioception refers to the ability to perceive the position and movement of body segments in space. The cortical aspects of the proprioceptive afference from the body can be investigated using corticokinematic coherence (CKC). CKC accurately quantifies the degree of coupling between cortical activity and limb kinematics, especially if precise proprioceptive stimulation of evoked movements are used. However, there is no evidence on how volitional muscle activation during the proprioceptive stimulation affects CKC strength. Twenty-five healthy volunteers (28.8 ± 7 yr, 11 females) participated the experiment that included electroencephalographic (EEG), electromyographic (EMG) and kinematic recordings. 2-Hz ankle-joint rotations were elicited through a movement actuator in two conditions: passive condition with relaxed ankle and active condition with constant 5-Nm plantar flexion exerted during the stimulation. In total, 6-min of data were recorded per condition. CKC strength was defined as the maximum coherence value among all the EEG channels at the 2-Hz-movement frequency for each condition separately. Both conditions resulted in significant CKC peaking at the Cz electrode over the foot area of the primary sensorimotor (SM1) cortex. Stronger CKC was found for the active (0.13 ± 0.14) than passive (0.03 ± 0.04) condition (P < 0.01). The results indicated that volitional activation of the muscles intensifies the neuronal proprioceptive processing in the SM1 cortex. This finding could be explained both by peripheral sensitization of the ankle joint proprioceptors and central modulation of the neuronal proprioceptive processing in the spinal and cortical levels.
