EP 4. Recruitment of premotor cortices in subacute stroke patients – A longitudinal fMRI study
In order to investigate changes in functional representation of hand movement after stroke we used functional magnetic resonance imaging (fMRI) during an active motor task of the affected hand before and after a three week comprehensive motor training.

P 69 Assessing the relation between brain structure and function during motor imagery in stroke patients and controls using EEG and MRI
Motor imagery (MI) training, in particular in combination with EEG-based neurofeedback (MI-NF), has been suggested as a potential add-on therapy for rehabilitation of upper limb motor impairments after stroke. Most MI-NF implementations are based on the event-related desynchronization (ERD) in the 8 –30Hz frequency range that is typically observed over sensorimotor areas during motor execution and imagination. The amplitude and consistency of the ERD depends, among other things, on brain structure and function during motor imagery (e.g., Halder et al., 2013; Zich et al., 2015).

P 181. Impact of offline transcranial direct current stimulation on consolidation of motor sequence learning in healthy elderly subjects
Conclusions: Offline application of anodal tDCS over M1 post training improves consolidation of motor sequence learning in elderly subjects until at least 22h post training. Further studies are needed to investigate the potential benefit of offline-tDCS in motor learning in healthy elderly and stroke patients.

S14-4. Possibility of a useful intervention of exercise induced by muscle fatigue to change excitabilities of corticospinal and cortico-cortical tracts for functional recovery in neurorehabilitation
Motor learning and synaptic plasticity in the cortex are enhanced by interventions that reduce the effectiveness of GABAergic intracortical inhibition. The disinhibition of SICI by muscle fatigue could enhance synaptic plasticity and improve the consolidation of motor learning. We found that the corticospinal excitability and SICI decrease after exhaustive muscle contraction or muscle fatigue. It seems possible that decreased SICI can enhance synaptic plasticity if motor learning or skill training is combined with muscle fatigue. Interestingly, fatigue in muscles on the opposite side of the body or in lower limb muscles re...

IS 39. Enhanced visuo-spatial and language learning with tDCS
Efficacy and effectiveness of training in conditions like chronic post-stroke aphasia or neglect, or neurodegenerative disorders like mild cognitive impairment (MCI) and Alzheimer’s disease, remain moderate only. Thus, novel strategies to enhance training success and overall behavioural outcome are urgently needed. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation tool that is now being widely used in neuroscientific and clinical research in humans, modulating cortical excitability by application of weak electrical currents in the form of direct current brain polarization.In a series of st...

B-11. Application of EEG-based brain computer interface to movement and sensory disorders
To examine the effect of the EEG-based brain computer interface (BCI) training for patients with stroke, writer ’s cramp and neuropathic pain. Method: Using the EEG recorded with Ag/AgCl electrodes placed at C3 and C4, as designated according to the International 10/20 system, we gave real time visual feedback to the patients with PC monitor which is placed in front of them. Participants were required to im agine the affected wrist extending in stroke and neuropathic pain patients. Patients with writer’s cramp were requested to relax their wrist flexor while extending their wrist.

P 105. Efficacy of Anodal transcranial direct current stimulation in rehabilitation of motor hand function in chronic incomplete spinal cord injury may depend on sensory impairment: A pilot study
Introduction: Impairment of motor function in Spinal cord injury (SCI) is associated with reduction in the excitability of motor cortical (M1) representations to muscles (), while recovery is associated with representational plasticity (). Noninvasive brain stimulation (NBS) such as anodal transcranial direct current stimulation (atDCS) increases M1 excitability, and has beneficial effects on retention of motor skill training in both the healthy and chronic stroke survivor (). However, sensory impairment may independently predict limits of recovery of functional independence ().Objective: This pilot study included incomple...

One step backwards, two steps ahead: Amplifying movement errors to improve walking post-stroke
Treatments to rehabilitate walking following nervous system damage tend to focus on correcting or minimizing movement errors. For instance, treadmill training – a well-studied and widely-used form of locomotor therapy – is often accompanied by assistance from a therapist, or sometimes a robot, to guide leg movement towards an “ideal” trajectory (reviewed in ; ). For optimal outcomes, it may be important to introduce some variability in the path of the guided movement (). Nonetheless, these types of treatments emphasize the correction of abnormal gait kinematics and kinetics. Treadmill training has been shown to imp...

Changes in diffusion tensor tractographic findings associated with constraint-induced movement therapy in young children with cerebral palsy
Constraint-induced movement therapy (CIMT) involves the application of constraint applied to the unimpaired upper limb coupled with intensive training of unimanual skills in the hemiplegic arm (Hoare et al., 2007). CIMT has been studied extensively and found to be effective in the treatment of adult hemiparetic stroke (Sirtori et al., 2009). Several randomized clinical trials performed on children with cerebral palsy (CP) also demonstrated immediate gain in the frequency of use and improved movement efficacy of the impaired upper limb (Deppe et al., 2013; Hoare et al., 2007; Rostami and Malamiri, 2012).

Timing of motor cortical stimulation during planar robotic training differentially impacts neuroplasticity in older adults
Neurorehabilitation efforts have focused on intense structured interventions to promote neuroplasticity because stroke is a leading cause of long-term disability world-wide. Robotic rehabilitation devices assist massed practice of upper extremity movement at high repetition rates (Lo et al., 2010; Conroy et al., 2011). They can also be used to change the learning environment, e.g., provide assistance or resistance to the motor task or train new mappings for movement to environmental effect (Krebs et al., 1998; Stein et al., 2004; MacClellan et al., 2005).
