Purpose: Many studies have attempted to elucidate the motor recovery mechanisms of stroke. In the current study, we report on a patient with infarction who showed recovery of an injured corticospinal tract (CST), using diffusion tensor imaging (DTI). Methods: A 20-year-old male presented with severe paralysis of the left extremities following an infarction in the right corona radiate and basal ganglia. The patient showed good motor recovery as much as being able to manipulate object using his left hand and could walk independently on stairs at 9 months after onset. Results: At 1 month after onset, the right CST showed decreased fiber volume due to the partial injury at the level of the corona radiate, and no (motor evoked potential) MEP was evoked from the right hemisphere. By contrast, the results at 9 months showed increased fiber volume of the right CST and the amplitude of MEP had improved to normal range on TMS. Conclusion: These results suggest that the severely injured right CST and MEP amplitude had been recovered during 9 months. Therefore, this result has important implications for brain plasticity and brain rehabilitation in patients with infarction.

Purpose: We studied the correlation between BBS (Berg Balance Scale), Functional Reach Test (FRT), Timed-Up & Go test (TUG), Stability Index (STI), MBI (Modified Barthel Index), and Fall History. Methods: We recruited 20 stroke patients from the Gang Dong Gu Health Care Center in Seoul, Korea. All subjects could walk with or without an assisting device. Subjects first completed a questionnaire pertaining to their fall history and Activity of Daily Living (MBI), and then were evaluated with BBS, TUG, FRT, and STI. We used the Tetrax posturography system that calculates a STI based on fluctuations in vertical ground reaction forces. The data were analyzed using a Pearson Correlation Coefficient. Results: The BBS and FRT (p<0.05) and MBI (p<0.01) showed a significant positive correlation. BBS negatively correlated with STI and TUG (p<0.01). Fall history and BBS, TUG, MBI, FR, STI did not correlate. Conclusion: The BBS helps predict weight shifting, walking, and ADL, but is not good for predicting fall risk. So, we need to study about factors that affect falling.

Purpose: This study examined that effect of a change in balance index on ankle Kinesio taping, muscle strength exercises and taping after muscle strength exercises in 30 healthy adult subjects. Methods: The Sway Index of the left, right, front and back on stable, toes up and linear were compared using a Balance System, a balance experimental instrument. Results: The pre and post experimental balance index regarding stable, toes up, and linear were taken for the Kinesio taping group, lower extremities muscle strengthening group, and muscle strengthening with the Kinesio taping group. Statistically significant decreases were observed in all variables except for the left and right pre and post experiment results under stable conditions. Conclusion: The balance index of exercise with taping was lower than that of exercise only. There is a need for objective research on the long-term applications and post-exercise. The body balance appears to be influenced by ankle stabilization using taping.

Purpose: The purpose of this study was to investigate the effects of sexual abuse prevention education program linked to elementary physical and psychological development on sexual knowledge and attitude. Methods: The participants were the elementary school students of fifth and sixth grades in S city, South Korea (experimental, comparison, and control group=96, 96, and 74, respectively). The experimental group received sexual abuse prevention education linked physical and psychological development, 6 sessions (3 sessions are physical and psychological development educations and 3 other sessions are sexual abuse prevention educations). The comparison group received sexual abuse prevention educations, 3 sessions (the same curriculum of the experimental group). The control group didn't receive any sexual education. The data were analyzed by $x^2$ test and t-test, and ANOVA using the SPSS program. Results: The experimental group showed significantly better sexual knowledge and attitude than the comparison and control group. Conclusion: Sexual abuse prevention education program linked physical and psychological development is required for elementary school students, to improve the sexual knowledge and attitude.

Purpose: This study was conducted to define factors influencing health-related quality of life (HRQOL) in women undergraduates. Independent variables of physical activity, attitude to eating, satisfaction with body shape, stress and self-esteem were used to predict HRQOL. Method: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Participants were 245 women undergraduates who were recruited from July to September 2012. Result: The mean for the physical component summary (PCS) of HRQOL was 73.89, and for the mental component summary (MCS) was 68.45. There were significant correlations between attitude to eating, satisfaction with body shape, stress, self-esteem and the two components of HRQOL. The groups with minimal or health enhancing activity were significantly higher in PCS and MCS than the inactivity group. Stepwise multiple regression analysis indicated that 35% of the variance in PCS was significantly accounted for by self-esteem, perceived stress, attitude to eating, and physical activity, and 45% of the variance in MCS was significantly accounted for by perceived stress, self-esteem, attitude to eating, and satisfaction with body shape. Conclusion: The results indicate that these factors influencing HRQOL should be considered when developing programs to improve HRQOL for women undergraduates.

There was no significant difference in the CADR (Clean Air Delivery Rate) between physical aerosols, NaCl and smoke, and biological aerosols, airborne MS2 virus and P. fluorescens, which implicate that the hybrid-type of air purifier, applying the unipolar ion emission and the radiant catalytic ionization, imposed identical reduction effect on both physical aerosol and bioaerosol. Ventilation decreases the efficiency of air cleaning by unipolar ionization because high ventilation diminishes the particle concentration reduction effect. The particle removal efficiency decreases with increase in the chamber volume because of the augmented ion diffusion and higher ion wall loss rate. Particle size affects the efficiency of air ionization. The efficiency is high for particles with very small diameter because reduction of charge increases with particle size. If there is no increasing supply of ions, the efficiency of air cleaning by unipolar ionization increases with respect to initial concentration of particles because of the large space charge effect at high particle concentration and amplified electric field.

Purpose: The purpose of this study was to compare the effects of the FES-gait with augmented feedback training to the FES alone on the gait and functional performance in individuals with chronic stroke. Methods: This study used a pretest and posttest randomized control design. The subjects who signed the agreement were randomly divided into 12 experimental groups and 12 control groups. The experimental groups performed two types of augmented feedback training (knowledge of performance and knowledge of results) together with FES, and the control group performed FES on the TA and GM without augmented feedback and then walked for 30 minutes for 40 meters. Both the experimental groups and the control groups received training five times a week for four weeks. Results: The groups that received the FES with augmented feedback training significantly showed a greater improvement in single limb support (SLS) and gait velocity than the groups that received FES alone. In addition, timed up and go (TUG) test and six minute walk test (6MWT) showed a significant improvement in the groups that received FES with augmented feedback compared to the groups that received FES alone. Conclusion: Compared with the existing FES gait training, augmented feedback showed improvements in gait parameters, walking ability, and dynamic balance. The augmented feedback will be an important method that can provide motivation for motor learning to stroke patients.

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a valid and widely used instrument for the assessment of osteoarthritis patients. In this study, data was obtained from the out-patients with painful osteoarthritis of the knee. One hundred-three out-patients were interviewed by physical therapists. In an exploratory way, a Korean version of the KWOMAC was analyzed for unidimensionality, item separation, and item difficulty using the Winsteps programs. Ninety-five patients with osteoarthritis of the knee over 65 years were analyzed for Rash analysis. In the analysis several functional items poorly fit to the model. These items included "heavy domestic duties" and "standing". In the pain domain, one item ("at night while in bed") did not fit the model. In the stiffness domain one item ("after sitting, lying, or resting later in the day") did not fit the model. Although 4 items from the 3 domains (pain, stiffness, function domain) do not fit well, the KWOMAC domains were confirmed by Rasch analysis. Thus the KWOMAC needs to be further examined before it can be used to properly determine the health status of the elderly with OA.

Thirty healthy adults aged 20 to 29 with no history of musculoskeletal or neurogenic disorder volunteered for this study. The contract-relax with agonist contration(CRAC) was applied to the right hamstring muscles with the subject in the supine position. Each hamstring group was stretched on three sucessive days with several repetitions of the technique lasting 1min, 3min, and 5min. respectively. Hamstring extensibility at the knee(ROM) was measured before and after stretching using on electronic digital inclinometer(EDI). The results, namely the increase in ROM, were analysed using one-way repeated ANOVA at p<0.05. The differences were not significant. Possible factors influencing the results are excessive sensitibility of the measuring instrument, the psychological and physical status of the subjects, and the level of muscle fatigue. The mean increases in ROM were 3.0 at 1min., 2.6 at 3min, and 2.1 at 5min. Inclusion of a control group would have further defined the effects of the stretching technique.
