Purpose : The purpose of present study was to determine effects of a task-oriented circuit training(TOCT) for lower limb on walking ability after stroke. Methods : Twenty one chronic stroke patients participated. Participants were randomly divided into either TOCT group or control group(11 experimental, 10 control). All of participants were in-patients at local rehabilitation centre and had been receiving a traditional rehabilitation program, five days a week. TOCT group have additionally undergone for four weeks, three days a week, the TOCT program but control group was not received any additional program except the traditional rehabilitation program. The 10 m walking test (10MWT), the 2 min walking test (2MWT), the step test (ST) and the figure-8 walking test (F8WT) to measure a walking ability were carried out twice before and after training. Results : After participation in the program, subjects of TOCT demonstrated a significant improvement in the scores of the 10MWT, 2MWT, the ST, the F8WT. The control group had no change on the any tests. After the training, the results to improve significantly in TOCT group compared to post-test of control group were the time of 10MWT and the time and the step of curved walking of F8WT. Conclusion : The present study suggests that the TOCT program may become a useful strategy for enhancing walking ability in the rehabilitation of stroke patients.

This study investigated changes in salivary cortisol, lactic acid, and heart rate along the route during walking exercise in a forest environment for the purpose of reducing stress. Walking exercise in a forest environment was conducted on a Hill Type (Distance: 800m, Average slope 25°, Altitude 112m) and Step Type (Distance: 800m, Average slope 25°, Altitude 114m) routes for 10 female college students in their 20s. The subjects were asked to walk at a speed of 60 bpm. The resulting changes in salivary cortisol, lactate, and average heart rate during exercise were compared and analyzed using Repeated Measurement two-way ANOVA, and the maximum heart rate during exercise and average heart rate at rest were compared and analyzed using paired t-test, and the following results were obtained. First, there was no significant difference in salivary cortisol depending on the type and period of the forest, but it tended to gradually decrease. Second, there was a significant difference in lactic acid depending on the type and period, and it was higher in Step Type. Third, there was a significant difference in the average heart rate during exercise, and it was higher in Step Type. Fourth, there was a significant difference in maximum heart rate during exercise, and it was higher in Step Type. Fifth, there was no significant difference in average heart rate during rest. In summary, walking exercise in a forest environment can be effective for stress reduction for female college students in their 20s, but it appears that forest routes should be selected according to physical strength level, and walking exercise in a forest environment for long periods of time is not recommended. For this purpose, it is suggested that it is appropriate to select the Hill Type route.

Purpose : This study investigated the validity of crosswalk signal time length with regards to elderly stroke patients. Methods : We recruited 60 elderly adults sixty years of age or older for our study. The participants were divided into three groups.Group A consisted of 20 healthy participants with no walking aids. Group B consisted of 20 stroke patients with no walking aids. Group C consisted of 20 stroke patients using a cane as a walking aid. We measured the walking times of participants for 7 m, 14 m and 21 m lengths. Results : Using an independent t test, there was a statistically significant difference in the walking times between Group A and Group B for all lengths. There was a statistically significant difference in the walking times between Group A and Group C for all lengths. There was no statistically significant difference in the walking times between Group B and Group C. There was a statistically significant difference between the three group when using ANOVA. Conclusion : From the results of this study, we infer that the signal times at crosswalks are inappropriate for elderly stroke participants who use a cane as a walking aid. Therefore further research should be conducted to determine the appropriate amount of additional time needed for the elderly to safely cross the street.

Objective: The purpose of this study is to analyze the effects of aquatic walking exercise on gait and balance parameters of elderly women. Method: 15 elderly people were recruited for this study (age: 73.20±5.19 yrs, height: 153.87±3.36 cm, mass: 60.33±5.73 kg). All variables were measured using Gaitview AFA-50. The variables were the heel contact time ratio, gait angle, and M/P change ratio for gait patterns and ENV, REC, RMS, Total Length, TLC, Sway velocity, and Length/ENV for balance abilities. A paired t-test and the Wilcoxon signed-rank test were carried out to verify the differences in the test scores after participating in the water walking program. The significance level for all statistical analyses was set to α=.05. Results: As for the changes in their walking function after the exercise, heel contact time ratio (p<.01) showed a statistical significance, while gait angle and M/P change ratio did not reveal statistically significant differences. In the test of balance ability on both feet and with eyes opened, statistical significance was found in ENV, REC, RMS, TLC (p<.01), and sway velocity (p<.05), while the test with eyes closed showed statistical significance in length/ENV as well as ENV, REC, RMS, sway velocity (p<.01) TLC, and total length (p<.05). As for the single-leg stance balance ability, ENV and REC revealed statistically significant differences. Conclusion: These results show that water walking is effective for improving the function of the ankle flexor muscles, providing stability to the ankle joint during walking and helping efficient walk. In addition, it is also expected to help prevent falls due to loss of balance by improving the stability of lower extremity muscles and trunk.

PURPOSE: This study was conducted to analyze the effects of carrying weight on the gait of elderly women using a walking-assistant vehicle (WAV) as the weight increased. METHODS: A total of 30 elderly women living in the local community were included as subjects and instructed to walk 50 m using a WAV loaded with sandbags corresponding to 0%, 5%, 10%, or 15% of their mean weight. The subjects' gait was analyzed using a gait analyzer to measure stride length, step length, step width, and gait time. RESULTS: Stride and step lengths were longest when carrying 5% of their weight and shortest when carrying 15% of their mean body weight. Step width and gait time were lowest when carrying weights corresponding to 5% and highest for 15% of their mean body weight. When observing gait with a WAV, the gait time was greatly affected by weights, with carrying weight equivalent to 5% of the body weight positively affected the gait with a WAV, whereas carrying weights of >15% resulted in slower gait speed. CONCLUSION: When walking with a WAV, an appropriate carrying weight of approximately 5% of the body weight stabilizes gait, while a weight of 15% leads decreased gait efficiency. Therefore, when using a WAV during outdoor activities, elderly women should add some weight to the WAV; however, the carrying weight should be <15% of the body weight.

The purpose of this study is to elucidate the mechanical characteristics of lower extremity joint movements at different walking speeds in obese people and suggest the very suitable exercise for obese person's own body weight and basic data for clinical application leading to medical treatment of obesity. This experimental subjects are all males between the ages of 20 and 30, who are classified into two groups according to Body Mass Index(BMI): one group is 15 people with normal body weight and the other 15 obese people. Walking speed is analysed at 3 different speeds ($1.5^m/s$, $1.8^m/s$, $2.1^m/s$) which is increased by $0.3^m/s$ from the standard speed of $1.5^m/s$. We calculated joint moments of lower extremity during stance phase through video recording and platform force measurement.Two-way ANOVA(Analysis of Variance, Mix) is applied to get the difference of moments according to walking speeds between normal and obese groups. Pearson's Correlation Analysis is applied to look into correlation between walking speeds and joint moments in both groups. Significance level of each experiment is set as ${\alpha}=.05$. As walking speed increases maximum ankle plantar flexion moment in the stance phase is smaller in obese group than in normal group, which is suggestive of weak toe push-off during terminal stance in obese group, and the highest maximum ankle plantar flexion moment in obese group during the middle speed walking($1.8^m/s.$). Maximum ankle dorsal flexion moment in obese group is relatively higher than in normal group and this is regarded as a kind of compensatory mechanism to decrease the impact on ankle when heel contacts the floor. Maximum knee flexion and extension moments are both higher in normal group with an increase tendency proportional to walking speed and maximum hip flexion and extension moments higher in obese group. In summary, maximum ankle plantar flexion moment between groups(p<.025), maximum knee moment not in flexion but in extension(p<.001) within each group according to increasing walking speed, and maximum hip flexion and extension moment(p<.001 and p<.004, respectively according to increasing walking speed are statistically significant but knee and hip moments between groups are not. Pearson correlation are different: high correlation coefficients in maximum knee flexion and extension moments, in maximum hip extension moment but not hip flexion, and in maximum ankle dorsal flexion moment but not ankle plantar flexion, in each group. We suspect that equilibrium imbalance develops when the subject increases walking speed and the time is around which he takes his foot off the floor.

본 연구는 고령자에 대한 보행속도 및 인지-반응을 포함한 보행특성에 관한 기초자료를 조사하였으며, 이를 토대로 보행 신호시간을 산정하였다. 현장조사는 스탑워치를 이용하여 보행자의 실제 횡단시간을 조사하였고, 구두조사로 연령을 조사하여 일반인과 고령자그룹으로 구분하였다. 자료를 분석한 결과 일반인의 평균보행속도는 1.29m/s, 노인은 1.13m/s로 일반지역의 기준인 1.0m/s 보다 높게 나타났다. 또한 하위 15th percentile속도를 살펴보면 일반인은 1.01m/s, 노인은 0.85m/s로 분석되어 노인의 경우 일반지역 기준보다 낮은 보행속도를 가지며 보호구역 기준인 0.8m/s 보다는 높은 속도가 나타났다. 하지만 지팡이나 휠체어를 사용하는 노인의 경우 하위 15th percentile속도가 0.73m/s로 나타나 현재 보호구역 기준보다 낮은 보행속도를 가진 것으로 분석되었다. 본 연구결과는 향후 노인의 보행환경을 개선하는데 적용할 수 있고, 장기적으로는 교통약자의 이동성 증진에 기여할 것으로 판단된다.
