The Japanese rTMS experience – Present and future
Fig. 8 coil, which is popular now, was invented by Prof. Ueno in 1988 and spread globally. The rTMS machines were developed in Europe and imported to Japan from 2001 and spread over Japan. The clinical treatments with rTMS have been mainly used for Parkinson’s syndrome, neuropathic pain, depression and rehabilitation after stroke. rTMS of left dorsolateral prefrontal cortex (Neuronetics Inc) for depression is already used in Japanese private clinic, and will be approved by Japanese government in the near future.

rTMS and disorders of the motor system
Recent guidelines of the IFCN (Lefaucheur et al., 2014) on the therapeutic use of rTMS list the are variety of diseases. Here the focus will be laid on movement disorders, stroke and ALS.No recommendation for the antiparkinsonian effect can be made for high frequency (HF) or low frequency (LF) rTMS of the hand representation in M1 and for HF rTMS of the SMA. Only a possible antiparkinsonian effect of HF rTMS of bilateral (multiple) sites in M1 (Level C) emerged from this meta-analysis. A probable antidepressant effect of HF rTMS of the left DLPFC in Parkinson’s disease (Level B) emerged from the literature analysis.

ID 452 – Sympathetic skin response in stroke patients
Sympathetic dysfunction could lead to life-threatening complications. The aim of this study was to investigate the relationship between the size, location, nature of the lesion, and the sympathetic skin response (SSR).Thirty patients with stroke and 30 healthy subjects were included in this study. All patients were investigated by using brain imaging and clinical scales. SSRs were elicited on four extremities in both groups. Latency and amplitude values of the responses were measured. In the patient group, SSR were analyzed both in the early (in the first month) and the late stages (one month later first recording) of the patients.

ID 366 – Cerebral venous thrombosis (CVT) in a female patient with severe obstructive sleep apnea (OSAS): Case presentation
Obstructive sleep apnea syndrome is reported to be a risk factor for arterial ischemic stroke, however, relationship between OSAS and cerebral venous thrombosis (CVT) remains uncertain.

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.

ID 100 – Chronic post stroke central pain: Increased success rate of chronic epidural motor cortex stimulation using somatotopic, navigated repetitive TMS for patient selection and implant placement
The outcome at group level of neuromodulation for central pain using stimulation of motor cortices is limited, though for some, there are large effects. Thus, there is a need for selection of patients.

ID 12 – Cortical recovery from primary motor cortex (stroke) infarction evaluated at chronic stage

ID 394 – Polarity independent suppression of long-term associative plasticity in the human SMA–M1 network by simultaneous tDCS
Excitability and connectivity of the supplementary motor area (SMA) and primary motor cortex (M1) are important for motor rehabilitation after stroke. Previously, we demonstrated that paired associative stimulation of SMA and M1 (SMA–M1-PAS) by dual coil transcranial magnetic stimulation (TMS) may induce STDP-like plasticity in this network. Here, we tested the influence of transcranial direct current stimulation (tDCS) on SMA–M1 plasticity.

ID 430 – The value of the P300 event related potential in the ischemic stroke
So far, only little is known about the impact of stroke on Event Related Potentials. The aim of this prospective study was to follow-up P300 latencies and choice reaction time in stroke patients and evaluate their changes over a prospective 1-year follow-up period.

ID 297 – Changes in finger tapping-related desynchronization during motor stroke recovery
Complex mechanisms underlying stroke recovery and modulations of associated brain activities are still far to be well elucidated. Here we investigated the potential effects of motor stroke recovery on finger tapping-related (FTR) brain dynamics by using high-power EEG with 128 channels and 2048Hz sampling rate. A follow-up study was carried out on six patients with ischemic stroke. Patients were instructed to perform finger tapping with their right or left index finger at a pace determined by a visual cue.
