  • Background: The method of measuring the walking function of patients with chronic stroke differs depending on patients walking capability and environmental conditions. Objects: This study aimed to demonstrate the influences of walking capacity and environmental conditions on the results of short- and long-distance walk tests in patients with chronic stroke. Methods: Forty patients with chronic stroke volunteered for this study, and allocated to group-1 (<.4m/s, household walking, $n_1=13$), group-2 (.4~.8m/s, limited community ambulation, $n_2=16$), and group-3 (>.8m/s, community ambulation, $n_3=11$) according to their walking capacity. The 10-meter walk test (10MWT) and 6-min walk tests, (6MWT) were used to compare the short- and long-distance walk tests results, which were randomly performed under indoor and outdoor environmental conditions. Results: The comparison of the results obtained under the indoor and outdoor conditions revealed statistically significant differences between the groups in the 6MWT and 10MWT (p<.05). Post-hoc tests' results showed significant differences between groups-1 and -2 and between groups-1 and -3 in the 10MWT, and between group-1 and -3 in the 6MWT. Furthermore, in group-2 the 10MWT and 6MWT results significantly differed between the indoor and outdoor conditions, and the values measured under the indoor and outdoor conditions significantly differed between 10MWT and 6MWT (p<.05). Group-3 showed a significant difference in 10MWT results between the indoor and outdoor conditions (p<.05). Conclusion: These findings suggest that the results of the short- and long-distance walk tests may differ depending on the walking capacity of patients with chronic stroke and the environmental condition under which the measurement is made, and these effects were greatest for the patients with the limited community ambulation capacity.

  • Purpose : This study is designed to demonstrate the effects of circuit obstacle group gait training on walking ability and emotion in stroke patients. Methods : Twenty one patients with stroke were participated in this study. The subjects were divided into control group(n=10) and experimental group(n=11). Circuit obstacle group gait training consisted of walking around obstacles, walking over obstacles, walking up and down slopes and walking up and down stairs. Circuit obstacle group gait training was conducted five times per week, 1 hour per session, for 6 consecutive weeks. At pre-test and post-test, subjects were tested with 10 m walking test, timed up and go test, up and down 4 stairs test, depression and self esteem. Results : After 6 weeks of research, the experimental group showed statistically significant difference in all items when comparing prior to training and after training (p<.05), but the control group showed statistically significant difference in items other than depression and self esteem(p<.05). In the comparison between the two groups, the experimental group showed higher improvement than the control group in the 10 m walking test, timed up and go test, and up and down 4 stairs test, and there was statistically significant difference in decrease of degree in depression between the experimental group and control group(p<.05). Conclusion : This study have shown that circuit obstacle group gait training improves walking ability and emotion in stroke patients.

  • PURPOSE: This study compared two different techniques of treadmill gait training, and evaluated the outcomes on gait and respiratory function in patients with hemiplegic stroke. METHODS: This was a single-blinded, randomized, controlled, comparative study, enrolling a total of 21 stroke patients in a rehabilitation hospital. Subjects were randomly assigned to either the treadmill walking training group with gradual speed increase (GSI group, n = 10), or treadmill walking training group with random speed changing (RSC group, n = 11). All participants performed 60 min of comprehensive rehabilitation therapy (5 × / week for 6 weeks). In additional, each group received either GSI or RSC treadmill walking training for 20 min (5 × / week for 6 weeks, total 30 sessions). Gait and respiratory function were measured before and after the 6-week training. RESULTS: Both groups showed significant improvements in the 10-m walking test, 6-minute walking test, timed up and go test, forced vital capacity (FVC), forced expiratory volume in 1 second, and maximal voluntary ventilation after training (p < .05). The GSI group showed a significantly greater increase in the FVC than the RSC group (+14.8 L vs. +12.5 L, p < .05). CONCLUSION: Both training methods can be effective for improving the walking and respiratory functions of stroke patients. However, our results indicate that treadmill walking training with gradual speed increase might be a more effective method for improving the respiratory function (FVC) than treadmill walking training with random speed changing.

  • The purpose of this study was to examine the effects of hip joint mobilization (HJM) on walking ability, balance ability, and the joint range of motion in stroke patients to minimize the problems of the musculoskeletal system in patients with central nervous system diseases. All volunteers were randomly assigned to the HJM group ($n_1=14$) and the general neurodevelopment therapy (NDT) group ($n_2=16$). The HJM procedure involved applying Maitland mobilization techniques (distraction, lateral gliding, inferior gliding, and anterior gliding) by grade 3 to both hip joint. The mobilization process included mobilization and NDT for 15 min/day, 3 days a week for 4 weeks. The outcome measures were evaluated, including the hip joint passive range of motion (ROM) test and femur head anterior glide test (FHAG) using prone figure four test, dynamic and static balance abilities [timed up and go (TUG) test and center of pressure (COP) analysis], and walking ability [10-meter walking test (10MWT) and 6-min walking test (6MWT)]. Both the groups showed significant post-training differences in the hip joint ROM (FHAG and degree of hip extension) and 10MWT. The post-training improvements in the TUG test were significantly greater in patients of the HJM group than in the NDT group; however, there were no post-training improvements in COP in both groups. Patients in the HJM group showed post-training improvement in the 6MWT; however, statistically significant differences were not observed. Patients in the NDT group showed post-training improvements in the 6MWT. These results suggest that HJM improves hip joint ROM, dynamic balance ability, and walking speed in stroke patients. However, further studies are required to evaluate the long-term therapeutic efficacy of HJM in stroke patients.

  • There are many types of walking exercise. We have choice the way according to the walking exercise purpose. Nordic walking(NW) is one of walking types with nordic poles. Also, power walking(PW) has motion of large swing the arm in walking, and dumbbell walking(DW) way is walking with 3-pound dumbbell. This study compared the physiological response(heart rate, energy expenditure) of general walking(GW) to another types(nordic, power, and 3-pound hand weights walking way). Seven apparently male health volunteers between the ages 19 and 24 years participated. Each complete a treadmill test. The tests were assigned randomly, as submaximal walking trials on separate days. Each walking trial was conducted on a level treadmill, for 40 minutes(3-5mile/hour 5min warm-up, 6mile/hour speed for 15min walking and 7mile/hour speed for 15min Jogging exercise, and 5-3mile/hour cool down 5min), at an same pace. Heart rate in beats per minute(bpm), and energy expenditure in kcal per minute(kcal/min) were recorded each minute. Results between trials were compared using repeated measures analysis of variance and Tukey's post hoc tests. In slow walking, it was found that walking with 3-pound hand weight way resulted in and average of ($127.8{\pm}8.27bpm$) the highest score HR, Caloric expenditure($85.4{\pm}14.51kcal/min$), responses compared to regular walking way($117.4{\pm}7.27bpm$ and $70.4{\pm}10.99kcal/min$). Nordic walking way($121.4{\pm}11.74bpm$, and $77.0{\pm}16.83kcal/min$) is second, power walking way($118.5{\pm}9.98bpm$, and $68.7{\pm}20.62kcal/min$) is next. In fast walking, it was found that walking way with 3-pound hand weight resulted in and average of ($160.1{\pm}8.72bpm$) the highest score HR, caloric expenditure($126.1{\pm}13.86kcal/min$), responses compared to regular walking way($148.4{\pm}11.94bpm$, and $109.0{\pm}4.70kcal/min$). Nordic walking way($156.7{\pm}10.82bpm$, and $113.5{\pm}14.51kcal/min$) is second, power walking way($149.7{\pm}12.56bpm$, and $109.2{\pm}17.64kcal/min$) is next. Thus, it is the unavoidable conclusion that, comparing with general walking, 3-pound hand weight walking, nordic walking, and power walking methods have the advantage of high exercise intensity and energy expenditure to meet the purpose of performers without the problem. Furthermore, 3-pound hand weight walking ways were proved to be a useful aerobic exercise method as whole body that achieves high-energy efficiency. To this extent, 3-pound hand weight walking ways can be recommended as a continuous and regulative aerobic exercise for some people.

  • Purpose: The purpose of this study was to determine whether walking exercise improved physical function in elderly people using meta-analysis. Methods: Medical and nursing literature databases were searched to identify the studies on the effectiveness of walking exercise on physical function. In the databases, there were 16 articles reporting 21 interventions. Overall effect sizes for three outcome variables, elders' physical function in lower limb muscle endurance, whole body endurance and upper body flexibility, were calculated. Effects of study characteristics on outcome variables were analyzed. Results: The meta-analysis showed that walking exercise generally had positive effects on CST (chair stand test), 6MW (6 min walking), and SRT (standing or sitting reach test) with overall weighted effect sizes of 1.06, 0.41 and 0.29 respectively. This study also showed that the chronic disease status of the elders, intervention methods, and type of residence had different effects on CST, 6MW and SRT. Conclusion: The results indicate that walking exercise improves physical function in elders. Walking exercise which can be done at any time and any location is indeed a very effective exercise for elderly people.

  • The study aimed to compare the effect of the treadmill walking training combined with obstacle-crossing (TWT-OC) and treadmill walking training (TWT) on the walking function of patients with chronic stroke. 29 subjects volunteered to participate in this study; they were randomly assigned to either TWT-OC group (15 subjects) or TWT group (14 subjects). Subjects from the TWT-OC group underwent a treadmill walking combined with obstacles-crossing for 30 minutes daily, three days a week for four weeks, whereas subjects from the TWT group received only a treadmill walking. The 10 m walk test (10MWT), 6-min walk test (6MWT), berg balance scale (BBS), timed up and go test (TUG), activities-specific balance confidence-Korean version (ABC-K), and walking ability questionnaire (WAQ) were measured before and after the 4-week training. The TWT-OC group showed significantly better functional mobility of walking and balance measured by 6MWT (p<.01), BBS (p<.01), and TUG scores (p<.05) when compared with those of the TWT group. Further, within-group comparison showed significant improvement in all variables (p<.01) except for 10MWT. These findings suggest that the TWT-OC and TWT may be helpful for improving the walking function of patients with chronic stroke, and the TWT-OC has probably more favorable outcomes for chronic stroke, however, further trials with wider range of subjects are warranted for generalization and clinical relevance.

  • This study is the quasi-experimental study on the gait training rehabilitation. The purpose of this study is to prepare the baseline data for most suitable of gait while we were scrutinizing how the walking characters, functional walking ability, gait quality of stroke patients were affected by the gait on BWSTT (Body Weight Supported Treadmill Training) through the change of treadmill velocity and body weight support. To accomplish this purpose, this study used thirty subjects, more than 3 months post stroke, for rehabilitation who were divided between two gait training groups they received the neurophysiological physical therapy. For 6 weeks, 5 times a week for 15 minutes per session, the BWSTT group participated in 30 sessions structured speed-dependent treadmill training with 30% body weight supported, and the ratio of body weight support was gradually decreased as the patients advanced the capability of more self-support. The OGT(Over Ground Training) group received the same quantity of equal sessions like BWSTT. Firstly, we measured the absolute improvement of walking velocity (m/s), capacity(min/m) and cadence(steps/min) among walking characters. Secondly, we measured the functional walking ability such as Functional Ambulatory Category(FAC, score out of 5), Modified Motor Assesment Scale(MMAS, score out of 6) and Gait Quality Chart(score out of 41). Data analysis was performed with using SPSS 10.0 win program. The descriptive analysis was used to obtain average and standard deviation. The independent t-test and the paired t-test were used to compare both the groups about pre and post training test. Treatment effects were established by pre and post assessment. Subjects tolerated the training well without side-effects. Therefore, the results of this study were as follows; 1. There was a more significant difference from the improvement of walking velocity(0.09m/s), endurance(4.53min/m), cadence(4.20steps/min), FAC(0.26score), MMAS(0.33 score) and hip joint and pelvic of gait quality(0.39 score) ever before in the BWSTT group(p<.05). 2. There was a more significant increase from the walking velocity(0.01m/s) in the OGT group(p<.05). 3. There was a more statistical significant increase from comparing the average of walking velocity in both groups ever before(0.42m/s in BWSTT group and 0.31m/s in OGT group)(p<.05). There was a statistical significant difference from the average of cadence in both groups(61.87step/min in BWSTT group and 3.60steps/min in OGT group)(p<.05). As we can see from above, the findings suggest that BWSTT may be more effective than the OGT for improving some gait parameters such as gait velocity and cadency. This conclusion also suggest that BWSTT is more effective for the improvement of gait of stroke patients.
