P60. Direct and long term influence of cardiovascular training on cognition in subacute stroke patients
Rehabilitation of cognitive deficits has been voted ‘#1 research priority’ for patients suffering from stroke (Saunders et al., 2014). Aerobic fitness training may modulate cognitive performance either by enhancing neuroplasticity or by increasing brain oxygenation. The majority of studies in this area have focused on motor function; its effect o n cognitive performance is not well understood yet. The current study therefore aims to evaluate the influence of aerobic fitness intervention on cognitive functions in subacute stroke patients, and tries to elucidate the mechanisms underlying this effect.

Visual Rehabilitation Training Alters Attentional Networks in Hemianopia: an fMRI study
Post-geniculate damage of the visual system leads to homonymous hemianopia which affects about 30% or more of all cases of stroke or brain trauma (Pambakian et al. , 1997). Hemianopia greatly reduces quality of life, affecting reading, driving and spatial navigating of patients (Das et al. , 2010). Several strategies for visual field restoration have been introduced (for review see Sabel et al. (2011)). For example, Kasten et al. (1998) showed that patients trained with light detection tasks in areas of residual vision (ARV) had significantly enlarged visual fields.

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 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).

O204 Simultaneous bi-hemispheric repetitive transcranial magnetic stimulation for upper limb motor recovery in chronic stroke: A double blind placebo controlled study
repetitive transcranial magnetic stimulation (rTMS) is a promising intervention for the treatment of post-stroke motor deficits. Since the crucial role of non-primary motor cortices and contralesional brain areas is emerging for motor recovery in chronic stroke; we assessed safety and efficacy of bilateral rTMS over the motor areas associated to physical training (PT) on upper extremity (UE) motor function.

S185 The effect of bilateral arm training on motor areas excitability in chronic stroke patients
Physical therapy exercises that do not enhance motor areas neuroplasticity lead to motor impairment especially at the upper extremity (UE) in the chronic stroke patients. The aim of this study was to assess the effect of using bilateral arm training on motor areas excitability (neuroplasticity) in the chronic stroke patients.

EP 10. Home-based motor imagery training in chronic stroke supported by neurofeedback: A feasibility study
Chronic hemiparesis of an upper limp following stroke has been related to an over-involvement of the ipsilateral hemisphere that inhibits use of the affected limb. Interventions helping to shift back this altered lateralization have been suggested to positively affect upper limp functional recovery. One such intervention is the combination of motor imagery (MI) supported by EEG neurofeedback. However, cortical reorganization requires highly intensive practice. In this feasibility study this was achieved by implementing a mobile EEG neurofeedback system.

EP 2. Pyramidal tract FA predicts motor outcome in subacute stroke patients after a three week period of arm ability training for ADL-relevant hand motor tests
Outcome prediction after motor stroke for the acute to subacute phase can be consulted for individual therapy modification. For the outcome of severely impaired patients the intactness of the pyramidal tract descending from the lesioned hemisphere (ipsilesional; i) has been described as an important parameter for upper limb strength as a measure of motor outcome (Stinear et al., 2012). In addition, in chronic stroke fractional anisotrophy (FA) of the pyramidal tract is predictive for hand motor impairment in strength (Lindenberg et al., 2010).

EP 121. Motor sequence learning in patients with limb apraxia – The effects of long-term training
Recent studies show that limb apraxia is often not recognized as a higher motor impairment in patients suffering from a stroke. Because it is adversely affecting every-day life and personal independence, a successful rehabilitation of apraxia is critical for personal well-being (Cappa et al., 2005; Dovern et al., 2012). Yet, evidence of an effective treatment approach with long-lasting effects and generalization to untrained actions is still missing (Binkofski and Klann, 2013; Dovern et al., 2011).

ID 306 – Mirror-box training in healthy subjects and a patient with hemiparesis
Mirror therapy (MT) is an approach of neurorehabilitation improving motor functions after stroke. MT represents a mental process by which an individual rehearses a given motor action by reflecting movements of the non-paretic side in a mirror as if it were the affected side. Although a number of small-scale research studies have shown encouraging results, there is no clear consensus about the effectiveness of the therapy. The aim of this study is to investigate objective changes in EEG after MT.

Transcranial direct current stimulation in patients with chronic hand motor impairment after stroke
This study investigated the combined effects of anodal tDCS and intensive motor training (MT) vs. sham stimulation with MT (control intervention) on grip strength, motor performance and functional use of the affected arm.A total of 14 patients were randomly assigned to active stimulation treatment or a control intervention in a double-blinded, sham-controlled, parallel design. Each group received intensive MT for 45min/day, 5days/week, for 2weeks, preceded by 20min of 2mA anodal tDCS over the ipsilesional M1 vs.

P153. Correlation of cortical inhibition and motor performance after mental training with the hand in patients after stroke
This study explored if mental practice targeting the hand modulates cortical excitability and improves function of the affected hand. Transcranial Magnetic Stimulation (TMS) was used to measure changes in the duration of the cortical Silent Period (cSP) and to analyze the amplitudes of motor evoked potentials (MEPs).
