Perilesional reorg.nization of motor function in stroke patients

引用

Neural Reg.neration Research 2010年第21期5卷 1668-1672页

作者： Sung.Ho jang Department of Phy.ical Medicine and Rehabilitation College of Medicine Yeungnam University

Perilesional reorg.nization is an important recovery.mechanism for stroke patients because it y.elds g.od motor outcomes. However, perilesional reorg.nization remains poorly.understood. The scientific basis for stroke rehabilitation can be established when detailed mechanisms of recovery.are clarified. In addition, studies at the subcortical level remain in the early.stag.s. Therefore, the present study.sug.ested that additional investig.tions should focus on perilesional reorg.nization at the subcortical level, identify.ng.the critical period for this mechanism and determining.treatment strateg.es and modalities to facilitate development. The present study.reviews literature focused on perilesional reorg.nization in stroke patients with reg.rd to demonstration, clinical characteristics, and rehabilitative aspects, as well as previous studies of perilesional reorg.nization at cortical and subcortical levels.

Adaptive Parallel Computation for Blind Source Separation with Sy.tolic Architecture

引用

Intellig.nt Information Manag.ment 2010年第1期2卷 46-52页

作者： H. JEONg.y. KIM H. J. jang 不详

The purpose of Blind Source Separation (BSS) is to obtain separated sources from convolutive mixture inputs. Among.the various available BSS methods, Independent Component Analy.is (ICA) is one of the representative methods. Its key.idea is to repetitively.update and calculate the measures. However, dealing.with the measures obtained from multi-array.sensors causes obstacles for real-time use. In order to solve this problem, it is necessary.to convert the software implementation of BSS alg.rithm into the hardware architecture. Throug. the use of hardware architecture, the BSS alg.rithm can efficiently.work within a relatively.short time. In this study. we investig.te a practical method using.a parallel alg.rithm and architecture for hardware use in a blind source separation. We desig. a feedback network for real-time speech sig.al processing. The network is composed of forward and updates alg.rithms. The architecture of the network is sy.tolic and therefore it is suitable for parallel processing. We only.have to add and connect modules for scaling. This paper covers the process from the sy.tolic desig. of BSS to the hardware implementation using.Xilinx FPg.s. The simulation results of our proposed implementation are also represented in the experimental section. In that section, our architecture returns satisfy.ng.results with robust qualities.

Medial reorg.nization of motor function in corona radiata following.middle cerebral artery.infarction A case report

引用

Neural Reg.neration Research 2009年第9期4卷 668-671页

作者： Sung.Ho jang Department of Phy.ical Medicine & Rehabilitation Yeungnam University College of Medicine

Peri-lesional reorg.nization is one of the motor recovery.mechanisms following.stroke. A 23-y.ar-old female who presented with complete paraly.is of the rig.t extremities at the onset of infarct in the left middle cerebral artery.territory.was included. She slowly.recovered some function, and could extend the affected knee with resistance after 9 months. Diffusion tensor tractog.aphy. functional MRI, and transcranial mag.etic stimulation testing.were performed at 7 y.ars after onset. Results showed that diffusion tensor tractog.aphy.of the affected （left） hemisphere passed throug. the medial corona radiata at, or around, the wall of the lateral ventricle. The contralateral primary.sensorimotor cortex was activated during.affected knee movements. The motor-evoked potential, which was obtained from the affected leg. exhibited corticospinal tract characteristics. Results indicated that motor function of the affected leg.recovered via the corticospinal tract, which descended throug. the corona radiata medial to the infarct. The motor function of the affected leg.was reorg.nized to the medial corona radiata following.infarct to the middle cerebral artery.territory.

Isolated corticospinal tract in a patient with intracerebral hemorrhag. A diffusion tensor tractog.aphy.and transcranial mag.etic stimulation study

引用

Neural Reg.neration Research 2011年第7期6卷 558-560页

作者： Sung.Ho jang Department of Phy.ical Medicine and Rehabilitation College of Medicine Yeungnam University

Diffusion tensor tractog.aphy.allows visualization of the corticospinal tract （CST） in three dimensions. Transcranial mag.etic stimulation offers a unique advantag. in that it can disting.ish between the corticospinal tract and the non-CST by.analy.ing.the characteristics of a motor-evoked potential. A 15 y.ar-old female showed rig.t hemiparesis, due to intracerebral hemorrhag. in the left corona radiata, and the posterior limb of the internal capsule. Diffusion tensor tractog.aphy.revealed that the tracts of both hemispheres orig.nated from the precentral g.0}us, and descended throug. the known CST pathway. Specifically. the tract of the affected hemisphere descended throug. an isolated area in the leukomalactic lesion at the posterior limb level. In addition, the characteristics of the motor-evoked potential obtained from the rig.t hand when stimulating.the hot spot of the left motor cortex corresponded to a CST. In conclusion, we report on a patient with intracerebral hemorrhag. who showed an isolated CST in a leukomalactic lesion. This result sug.ests the importance of saving.the adjacent area or penumbra around a hematoma after an intracerebral hemorrhag..
