  • In this paper, we have developed a portable acceleration measurement system to measure acceleration signals during walking and a gait analysis algorithm which can evaluate gait regularity and symmetry and estimate gait parameters automatically. Portable acceleration measurement system consists of a biaxial accelerometer, amplifiers, lowpass filter with cut-off frequency of 16Hz, one-chip microcontroller, EEPROM and RF(TX/RX) module. The algerian includes FFT analysis, filter processing and detection of main peaks. In order to develop the algorithm, eight hemiplegic patients for training set and the other eight hemiplegic patients for test set are participated in the experiment. Acceleration signals during 10m walking were measured at 60 samples/sec from a biaxial accelerometer mounted between L3 and L4 intervertebral area. The algorithm, detected foot contacts and classified right/left steps, and then calculated gait parameters based on these informations. Compared with video data and analysis by manual, algorithm showed good performance in detection of foot contacts and classification of right/left steps in test set perfectly. In the future, with improving the reliability and ability of the algerian so that calculate more gait Parameters accurately, this system and algerian could be used to evaluate improvement of walking ability in hemiplegic patients in clinical practice.

  • Dyke-Davidoff-Masson Syndrome (DDMS) is a rare condition characterized by asymmetry of cerebral hemispheric growth with atrophy on one side, ipsilateral compensatory osseous hypertrophy, and contralateral hemiparesis. We experienced a 17 month-old male who presented with left focal clonic or tonic-clonic seizures accompanied by left hemiparesis and developmental delay. Brain MRIs demonstrated progressive atrophy of the right cerebral hemisphere with dilatation of the lateral ventricle, expansion of the ipsilateral frontal sinus with calvarial thickening, and elevation of the petrous pyramid and orbital roof. Brain SPECT showed a decreased volume of the right hemisphere with reduced blood flow. We therefore report a case of DDMS with a review of the literature.

  • The purpose of this study is to evaluate the effects of Action-observational training program on gait and balance of patients with hemiplegia. Subjects of this study, among the patients who received the diagnosis cerebral vascular accident, for patients total of 4 people have agreed to research. Experimental group 2 people, control group 2 people, was a total of 4 people. Group-specific arbitration method, was applied to Action-observational training program(experimental group) and general Task-oriented training program(control group). Each training courses 30 minutes for 4 weeks, examined the changes in 10 Meter Walk Test(10MWT), gait speed, Berg Balance Scale(BBS) and time up and go(TUG) ability to examine a total of 4-week course effectively. The intervention were compared by measuring before and after. There were significant improvements in the subscales of the gait and balance test of those who practiced with the Action-observational training program, while the control group showed no significant changes. Therefore, Action-observational training program is effective in improvement of to improve the gait and balance in patients with hemiplegia.
