“…By reanalysing the same data, we could also show that the magnitude of the TRPNS -30 effect was the same as it would have been if we had timed the stimulus with respect to the PN CNV (TRPNS CNV ). Indeed, this is not so surprising because several previous studies show that, in cue-guided paradigms similar to the one employed in the present study, the PN CNV occurs just before the EMG onset (Mrachacz-Kersting et al 2012;Jochumsen et al 2015;Martínez-Expósito et al 2017). In this sense, it has been previously suggested that the motor potential observed in the EEG in planned movements is associated with the point at which CSE starts to raise just before EMG onset (Chen et al 1998).…”

We compare the effects on corticospinal excitability of repeatedly delivering peripheral nerve stimulation at three time points (−30 ms, 0 ms, +50 ms) relative to muscle onset in a cue-guided task. r Plastic changes in excitability are only observed when stimuli are delivered immediately before the time when muscles activate, while stimuli delivered at muscle onset or shortly later (0, +50 ms) have no effect. r Plastic effects are abolished if there is ongoing volitional electromyogram activity in the muscles prior to the onset of the phasic contraction. r The plastic effects induced by timing peripheral stimulation relative to electromyographic markers of muscle activation are as effective as those that occur if stimulation is timed relative to electroencephalographic markers of motor cortical activation. We provide a simple alternative protocol to induce plasticity in people in whom electroencephalogram recording is difficult.

“…Moreover, no interventions so far have tested BMI platforms decoding pre-movement BP and ERD patterns online in patients with brain damage due to a stroke. While BP detections online in healthy subjects doing ankle dorsiflexions have demonstrated to be reliable for BMI approaches, BPs in upper-limb movements (Hadsund et al, 2016 ; Martínez-Expósito et al, 2017 ), and specially in stroke patients (Daly et al, 2006 ) present particularities that make them less reliable for BMI applications, which may limit their usability in BMIs. Recently, it was demonstrated that an appropriate combination of BP- and ERD-based classifiers could lead to reliable and low-latency estimation of stroke patients' upper-limb motor intentions (Ibáñez et al, 2014a , b ).…”

Low Latency Estimation of Motor Intentions to Assist Reaching Movements along Multiple Sessions in Chronic Stroke Patients: A Feasibility Study

et al. 2017

Background: The association between motor-related cortical activity and peripheral stimulation with temporal precision has been proposed as a possible intervention to facilitate cortico-muscular pathways and thereby improve motor rehabilitation after stroke. Previous studies with patients have provided evidence of the possibility to implement brain-machine interface platforms able to decode motor intentions and use this information to trigger afferent stimulation and movement assistance. This study tests the use a low-latency movement intention detector to drive functional electrical stimulation assisting upper-limb reaching movements of patients with stroke.Methods: An eight-sessions intervention on the paretic arm was tested on four chronic stroke patients along 1 month. Patients' intentions to initiate reaching movements were decoded from electroencephalographic signals and used to trigger functional electrical stimulation that in turn assisted patients to do the task. The analysis of the patients' ability to interact with the intervention platform, the assessment of changes in patients' clinical scales and of the system usability and the kinematic analysis of the reaching movements before and after the intervention period were carried to study the potential impact of the intervention.Results: On average 66.3 ± 15.7% of trials (resting intervals followed by self-initiated movements) were correctly classified with the decoder of motor intentions. The average detection latency (with respect to the movement onsets estimated with gyroscopes) was 112 ± 278 ms. The Fügl-Meyer index upper extremity increased 11.5 ± 5.5 points with the intervention. The stroke impact scale also increased. In line with changes in clinical scales, kinematics of reaching movements showed a trend toward lower compensatory mechanisms. Patients' assessment of the therapy reflected their acceptance of the proposed intervention protocol.Conclusions: According to results obtained here with a small sample of patients, Brain-Machine Interfaces providing low-latency support to upper-limb reaching movements in patients with stroke are a reliable and usable solution for motor rehabilitation interventions with potential functional benefits.

“…Within the 59 studies included, 53 studies used an observational design, while six used an experimental paradigm. Of the observational research, 25 studies utilized a single group, cross-sectional, multiple condition protocol, where two or more movements were compared in the same participants ( Jung, 1982 ; Yazawa et al, 1997 ; Bayliss and Ballard, 2000 ; Do Nascimento et al, 2005 ; Jacobs et al, 2011 ; Welke et al, 2011 ; Fromer et al, 2012 ; Zaepffel and Brochier, 2012 ; Kourtis et al, 2013 ; Bulea et al, 2014 ; Jiang et al, 2015 ; Euler et al, 2016 ; Koester and Schack, 2016 ; Varghese et al, 2016 ; Martinez-Exposito et al, 2017 ; Peters et al, 2018 ; Schwarz et al, 2018 ; Nann et al, 2019 ; Berchicci et al, 2020 ; Braquet et al, 2020 ; Chaisaen et al, 2020 ; Reiser et al, 2020 ; Tomyta and Seki, 2020 ; Jochumsen and Niazi, 2020b ; Schwarz et al, 2020b ).

“…Of the observational research, eight studies compared differences between simple and complex movements (e.g., ankle dorsiflexion compared with forward stepping, 1-ball versus 2-ball juggling, large-target versus small-target throwing) ( Vidailhet et al, 1993 , 1995 ; Yazawa et al, 1997 ; Fromer et al, 2012 ; Berchicci et al, 2017 ; Martinez-Exposito et al, 2017 ; Rashid et al, 2018 ; Tomyta and Seki, 2020 ). In six of these eight studies, MRCP amplitudes were significantly larger in more complex movement tasks ( Vidailhet et al, 1993 , 1995 ; Yazawa et al, 1997 ; Fromer et al, 2012 ; Berchicci et al, 2017 ; Tomyta and Seki, 2020 ).…”

Electroencephalographic Recording of the Movement-Related Cortical Potential in Ecologically Valid Movements: A Scoping Review

et al. 2021

View full text Add to dashboard Cite

The movement-related cortical potential (MRCP) is a brain signal that can be recorded using surface electroencephalography (EEG) and represents the cortical processes involved in movement preparation. The MRCP has been widely researched in simple, single-joint movements, however, these movements often lack ecological validity. Ecological validity refers to the generalizability of the findings to real-world situations, such as neurological rehabilitation. This scoping review aimed to synthesize the research evidence investigating the MRCP in ecologically valid movement tasks. A search of six electronic databases identified 102 studies that investigated the MRCP during multi-joint movements; 59 of these studies investigated ecologically valid movement tasks and were included in the review. The included studies investigated 15 different movement tasks that were applicable to everyday situations, but these were largely carried out in healthy populations. The synthesized findings suggest that the recording and analysis of MRCP signals is possible in ecologically valid movements, however the characteristics of the signal appear to vary across different movement tasks (i.e., those with greater complexity, increased cognitive load, or a secondary motor task) and different populations (i.e., expert performers, people with Parkinson’s Disease, and older adults). The scarcity of research in clinical populations highlights the need for further research in people with neurological and age-related conditions to progress our understanding of the MRCPs characteristics and to determine its potential as a measure of neurological recovery and intervention efficacy. MRCP-based neuromodulatory interventions applied during ecologically valid movements were only represented in one study in this review as these have been largely delivered during simple joint movements. No studies were identified that used ecologically valid movements to control BCI-driven external devices; this may reflect the technical challenges associated with accurately classifying functional movements from MRCPs. Future research investigating MRCP-based interventions should use movement tasks that are functionally relevant to everyday situations. This will facilitate the application of this knowledge into the rehabilitation setting.
