PURPOSE: To evaluate the effect of weight shift training with Hula Hoop on weight shift change and gait in stroke patients. METHODS: Ten stroke patients were enrolled in this study, and randomly divided into 2 groups. The study group underwent weight shift training with Hula Hoop, while the control group received general physical therapy that included weight shift training. All the studies were performed over a period of 4 weeks. Before and after the intervention, plantar pressure and performance in the 10 m walk test (10MWT) were assessed. Wilcoxon signed ranks test was used to compare the change from before to after the intervention in each group. The differences between the study and control groups were analyzed by using the Mann-Whitney test. RESULTS: After 4 weeks of intervention, the change in weight shift and performance in the 10MWT from before to after the experiment showed no statistical significance (p>.05). In addition, the comparison between the groups showed no significance in terms of weight-shift change, and performance in the 10MWT (p>.05). CONCLUSION: Although the difference was not statistically significant, the degree of improvement was similar to that attained with the conventional exercise treatment related to weight- shift training. During the course of the treatment, the patients received feedback through repeated training by themselves. Weight-shift training with Hula Hoop would be effective in improving the walking ability and weight-shifting on the paralyzed side of stroke patients. In the future, the effectiveness of this training would need to be validated.

The purpose of this study is to systematically determine an optimal percentile cut-off in histogram analysis for calculating the mean parameters obtained from a non-Gaussian continuous-time random-walk (CTRW) diffusion model for differentiating individual glioma grades. This retrospective study included 90 patients with histopathologically proven gliomas (42 grade II, 19 grade III, and 29 grade IV). We performed diffusion-weighted imaging using 17 b-values (0-4000 s/mm²) at 3T, and analyzed the images with the CTRW model to produce an anomalous diffusion coefficient (D_m) along with temporal (𝛼) and spatial (𝛽) diffusion heterogeneity parameters. Given the tumor ROIs, we created a histogram of each parameter; computed the P-values (using a Student's t-test) for the statistical differences in the mean D_m, 𝛼, or 𝛽 for differentiating grade II vs. grade III gliomas and grade III vs. grade IV gliomas at different percentiles (1% to 100%); and selected the highest percentile with P < 0.05 as the optimal percentile. We used the mean parameter values calculated from the optimal percentile cut-offs to do a receiver operating characteristic (ROC) analysis based on individual parameters or their combinations. We compared the results with those obtained by averaging data over the entire region of interest (i.e., 100th percentile). We found the optimal percentiles for D_m, 𝛼, and 𝛽 to be 68%, 75%, and 100% for differentiating grade II vs. III and 58%, 19%, and 100% for differentiating grade III vs. IV gliomas, respectively. The optimal percentile cut-offs outperformed the entire-ROI-based analysis in sensitivity (0.761 vs. 0.690), specificity (0.578 vs. 0.526), accuracy (0.704 vs. 0.639), and AUC (0.671 vs. 0.599) for grade II vs. III differentiations and in sensitivity (0.789 vs. 0.578) and AUC (0.637 vs. 0.620) for grade III vs. IV differentiations, respectively. Percentile-based histogram analysis, coupled with the multi-parametric approach enabled by the CTRW diffusion model using high b-values, can improve glioma grading.

Background: This study analyzed the reliability of smart guides for gait analysis in patients with stroke. Design: Cross-sectional study. Methods: The participants of the study were 30 patients with stroke who could walk more than 10 m and had an MMSE-K test score of ≥24. Prior to the experiment, the subjects or their guardians entered their demographic characteristics including gender, age, height, weight into the prepared computer. The experiment was conducted in a quiet, comfortable, and independent location, and the patient was reminded of the equipment description, precautions, and safety rules for walking. A smart insole was inserted into the shoes of the patients and the shoes were put on before the patients walked three times on the 5-m gait analysis system mat installed in the laboratory. Results: The reliability of the equipment was compared with that of the gait analysis system, and the results of this study are as follows: among the gait analysis items, velocity had an ICC=0.982, the cadence had an ICC=0.905, the swing phase on the side of the gait cycle had an ICC=0.893, the swing phase on the side of the gait had an ICC=0.839, that on the non-affected side had an ICC=0.939, single support on the affected side had an ICC=0.812, and support on the non-affected side had an ICC=0.767. Conclusion: The results of this study indicate no statistical difference between the smart insole and the gait analysis system. Therefore, it is believed that real-time gait analysis through smart insole measurement could help patients in rehabilitation.

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.

Objective: This study was conducted to investigate the effect of heel-raise-lower exercise on spasticity, strength, and gait speed after the application of tapingin patients with stroke. Design: Randomized controlled study Methods: The participants were randomly divided into the heel raise-lower exercise+taping (HREx+T) group and the heel raise-lower exercise (HREx) group, with 20 participants assigned to each group. Both groups performed heel lifting exercise 100 times a day 5 times a week for 6 weeks. HREx+T group additionally applied taping to the plantar flexor muscles. The spasticity of the ankle plantar flexors was measured using the composite spasticity score. A handheld dynamometer and a 10-m walk test were used to measure plantar flexor strength and gait speed, respectively. Results: Spasticity was significantly more improved in the HREx+T group than in the HREx group (p<0.05). Similarly, plantar flexor strength was significantly more improved in the HREx+T group than in the HREx group (p<0.05). Moreover, participants assigned to the HREx+T group showed significantly greater improvement in gait speed than those in the HREx group(p<0.05). Conclusions: Thus, heel-raise-lower training combined with taping may be used to improve the spasticity, muscle strength and gait speed in stroke patients.

This study examines the effects of different environments on the application of hemiplegia patients circuit balance training. Group 1 performed circuit balance training without any auditory intervention Group 2 performed training in noiseless environments and Group 3 performed training in white noise environments. First, among lower extremity muscular strength evaluation items, maximum activity time(MAT) was not significantly different(p>.05). Maximum muscle strength(MMS) increased significantly in Group 3(p<.01), there was no significant difference in MMS among the groups. Average muscle strength(AMS) indexes also significantly increased in Group 3(p<.01), there was no significant difference in AMS among the groups. Second, among balancing ability evaluation items, Berg's balance scale(BBS) scores significantly increased in all groups(p<.05), BBS scores were significantly difference among the groups. Based on the results, Group 1, 2 and Group 1, 3 showed significant increases (p<.05). Functional reach test(FRT) values significantly increased in Group 2, 3(p<.05), and there was no significant difference in FRT values among the groups. Timed up and go(TUG) test values significantly decreased in Group 2, 3(p<.05), and there was no significant difference in TUG test values among the groups. Third, among walking speed evaluation items, the time required to walk 10m significantly decreased in all groups(p<.05), and there was no significant difference in the values among the groups. Average walking speeds showed significant increases in Group 1, 3(p<.05), and there was no significant difference in the values among the groups. Based on the results of this study, noise environments should be improved by either considering auditory interventions and noiseless environments, or by ensuring that white noise environments facilitate the enhancement of balancing ability.

Objective: The present study was to investigate the discrimination capacity of the Performance Oriented Mobility Assessment-Gait Scale (POMA-GS), for predicting falls in stroke survivors. Design: Retrospective cohort study. Methods: Data including the characteristics and number of falls of 52 chronic stroke patients from a rehabilitation center were collected. The number of falls each subject had experienced in the previous year were investigated through interviews. The subjects were divided into two groups depending on the number of falls: if falls occurred twice or more on the basis of the time of study after stroke, they were defined as the falls group and if there was no fall experience or one fall, they were defined as the non-falls group. The subjects were examined with the POMA-GS, and physical functions were examined using by the One Leg Stand Test (OLST), Sit to Stand Test (SST), 10-m Walk Test, Lower Extremity in Fugl-Meyer assessment (FM-LE), and Trunk Impairment Scale (TIS). The validity of POMA-GS for falls prediction was analyzed. Results: In the POMA-GS, which predicts falls in stroke survivors, the cut-off value was 8.5 (sensitivity 72%; specificity 65%) and the area under the curve was 0.75 (95% confidence interval: 0.60-0.90, p<0.007). There was a significant difference in the OLST, SST, FM-LE, and TIS between the subjects with POMA-GS >8.5 and the subjects with POMA-GS ${\leq}8.5$. Conclusions: The POMA-GS could be a useful tool in predicting falls in stroke survivors, as its discrimination capacity and predictive validity is proven satisfactory.

Background: Most Pilates programs for older adults have been based on mat Pilates, and there has been limited research on Pilates with mini-balls. Therefore, this study aims to compare the effects of Pilates with mini-balls and mat Pilates interventions on strength, total body endurance, flexibility, and dynamic equilibrium to determine the differences. Methods: The elderly aged 65 or older living in Gyeongsan, Daegu, were divided into two groups, and the experimental group (n=10) conducted a Pilates exercise program using mini balls for 12 weeks, and the control group (n=10) conducted a mat Pilates exercise program for 12 weeks without mini balls. Strength, endurance, flexibility, and dynamic equlibrium were measured as a pre-test, and post-test was performed in the same way after 12 weeks of application. Results: Comparing the mini-ball Pilates group to the mat Pilates group, there was a significant difference (p<.05) in the 'chair sit and reach' after the intervention. In the within-group comparison, there was a significant increase (p<.05) in 'arm curl right', '30-second chair stand', '2-minute walk', 'back scratch', 'chair sit and reach', and '2.44m up and go' in the experimental group using the mini-ball Pilates program. Mat Pilates program significantly increased the within-group comparisons in '30-second chair stand' and 'chair sit and reach' (p<.05). Conclusion: It is suggested that mini-ball Pilates has a positive effect on the senior fitness and will be a good exercise method for using it as an exercise program for the elderly in the future.
