Purpose:The present study was to examine the difference and severity of asymmetry in independently ambulating stroke survivors and to establish the association between gait asymmetry, velocity, and the motor function of lower extremity. Methods:The subjects used in this study were 43 subjects with hemiparesis being able to walk independently. Motor function of lower extremity was measured clinically with the Fugl Meyer-Lower /Extremity Assessment. Overground gait velocity and spatio-temporal parameters were collected by the GAITRite system. Results:Thirty(69.77%) patients showed statistically significant temporal asymmetry while 28(65.1%) exhibited statistically significant spatial asymmetry. One-way ANOVA results showed a main effect of temporal symmetry group(normative, mild, severe) for gait velocity(F=74.129), FM-L/E(F=17.270), swing-stance symmetry(F=66.869, F=13.485, respectively), spatio-temporal symmetry(F=13.166, F=31.800, respectively) 66, F=31.800, respectively). Gait velocity was negatively associated with temporal asymmetry(r=-.83), spatial asymmetry(r=-.60). Motor function of lower extremity was also associated with temporal asymmetry(r=-.58), and spatial asymmetry(r=-.50). Conclusion:The study attempted to establish the standard assessment of hemiparesis gait symmetry in light of the complex relationship with motor impairment and gait velocity. More future work will need to link the degree of gait asymmetry to clinically relevant outcomes to better establish the clinical significance of such observations.

Purpose : The purpose of this study is to examine the effect of different heel heights on gait deviation and balance. Method : Participants were 16 women majoring in physical therapy in Kyungbuk college, located in Yeong-ju, North Kyungsang Province. Balance and gait patterns were measured by Good Balance and GAIT Rite. Result : Statistically significant differences were found in swing right measured by Gait-rite, and also in Analyze End, Ant-post, Med-Lat, and gait ability score(p < .05) regarding dynamic balance ability. Conclusion : There was no statistically significant difference in gait ability between those who walked barefoot and highheeled. However, balance ability was different "between them". This shows that heel height can lead to decrease in gait ability. Further research should include more participants and use a wide range of heel heights.

Purpose : This study examines the effect of trunk stabilization program on the body balance, lung capacity, and muscular activity of the rectus abdominis and external oblique of healthy adults. Method : A survey was conducted for 20 students of K University located in the city of Y in Gyeongsangbuk-do Province of Korea. The trunk stabilization program consisted of a hollowing exercise, curl-up, bridging exercise, and birddog exercise. This was performed 14 times in total (7 times a week for two weeks). For analysis, good balance was used to measure both static and dynamic balancing ability. A peak flow meter was used to measure the maximum expiratory flow, and MP150 was used to measure muscular activity of the rectus abdominis and external oblique. Result : After the trunk stabilization program, the participants showed a difference in score and time taken to achieve static and dynamic balance, and muscular activity of the rectus abdominis and external oblique at a statistically significant level (p<0.05). However, no significant difference was observed in the left-to-right distance and front-to-back distance in a dynamic balance, and the lung capacity (p>0.05). Conclusion : The results showed that the trunk stabilization program was effective in enhancing both static and dynamic balancing ability and muscular activity. It also increased the lung capacity although the change was not at a statistically significant level.

Purpose:The purposes of this study were to find correlations among Fugl-Meyer Assessment Scale, walking velocity, walking asymmetry and balance ability. Methods:The study sample consisted of 50 stroke patients referred to the Department of Rehabilitation Medicine in the Sanggye Paik, Ilsan Paik, Seoul Paik, and Dobong Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed on Fugl-Meyer Assessment scale and walking velocity, walking asymmetry. The data were analyzed using independent t-test, ANOVA, and multiple regression. Results:The results revealed that upper extremity coordination, balance and pain items of Fugl-Meyer Assessment scale were significantly correlated with walking velocity and upper extremity and upper extremity motor and balance items of Fugl-Meyer Assessment scale were significantly correlated with walking asymmetry. Fugl-Meyer Assessment scale was not significantly correlated with Static Balance Index, Dynamic Balance Index and Weight Distribution Asymmetry Index. Their power of explanation regarding comfortable walking velocity and comfortable walking asymmetry were 60.3%, 42.5% respectively. Conclusion:These results showed that Fugl-Meyer Assessment scale is significantly correlated with walking velocity, asymmetry and not significantly correlated with balance ability. Therefore Fugl-Meyer Assessment scale is an appropriate assessment tool to predict walking ability of patients with stroke. Futher study about walking velocity and asymmetry by change of Fugl-Meyer Assessment scale is needed using a longitudinal study design.
