Purpose: The purpose of this study was to examine the effect of weight-bearing training with an elastic band during functional electrical stimulation (FES) on walking and balance functions in stroke patients. Methods: Twenty patients with chronic stroke were divided into an experimental group assigned to weight-bearing training with an elastic band during functional electrical stimulation (FES; n=10) and a control group assigned to weight-bearing training alone during FES (n=10). The patients in both groups attended physical therapy sessions five times a week for four consecutive weeks. The experimental group underwent weight-bearing training with an elastic band during FES five times a week for four weeks. The control group underwent weight-bearing training during FES. Balance parameters were measured before and after the intervention using the Balancia program. Moreover, all patients were evaluated using the Berg Balance Scale (BBS), the Time Up and Go Test (TUGT), and the Wisconsin Gait Scale (WGS) before and after each intervention. Results: The results showed that weight-bearing training with elastic bands during FES and weight-bearing training during FES had a significant effect on the affected side's weight-bearing ratio, BBS, TUGT, and WGS in both groups (p <0.05). Additionally, the results showed that the changes observed in the two groups indicate significant differences in path length, average speed, BBS score, TUGT time, and WGS score between the groups (p < 0.05). Conclusion: In patients with stroke, weight-bearing training with an elastic band during FES affected on walking and balance. Therefore, it is an optional intervention for the balance and walking ability of stroke patients.

Background: This study investigated the effect of robot-assisted arm training on muscle activity of arm and weight bearing in stroke patients. Methods: The study subjects were selected 20 stroke patients who met the selection criteria. 10 people in the robot-assisted arm training group and 10 people in the task-oriented arm training group were randomly assigned. The experimental group performed robot-assisted arm training, and the control group performed task-oriented arm training for 6 weeks, 5 days a week, 30 minutes a day. The measurement tools included surface electromyography and smart insole system. Data were analyzed using independent sample t-test and the paired sample t-test. Results: Comparing the muscle activity of arm within the group, the experimental group and the control group showed significant differences in muscle activity in the biceps brachii, triceps brachii, anterior deltoid, upper trapezius, middle trapezius, and lower trapezius. Comparing the muscle activity of arms between the groups, the experimental group showed significant difference in all muscle activity of arm compared to the control group. Comparing the weight bearing within the groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings and there were significant differences in anterior and posterior weight bearing. The control group showed significant difference only in the non-affected side weight bearing. Comparing the weight bearings between groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings compared to the control group. Conclusion: This study confirmed that robot-assisted arm training applied to stroke patients for 6 weeks significantly improved muscle activity of arm and weight bearing. Based on these results, it is considered that robot-assisted arm training can be a useful treatment in clinical practice to improve the kinematic variables in chronic stroke patients.

Purpose: This study examined the effects of the symmetrical scapular alignment on the weight bearing of hemiplegic patients in the standing position. Methods: PALM (PALpation Meter) test and Gaitview AFA-50 were used to measure the skeletal alignment of the scapula and the weight bearing loaded on the affected and unaffected sides before and after training. The data was analyzed using a paired t-test on the SPSS 12.0 program for descriptive statistics. A p value <0.05 was considered significant. Results: The mean difference in the scapular alignments on sup. & mid. & inf. area in the hemiplegic side before and after training was $0.93\pm0.50cm$ and $0.58\pm0.43cm$, respectively. There was a significant decrease after training rather than that before (p<0.05). The mean weight bearing on the foot area in the hemiplegic patients before and after training was $9.12\pm5.51N/cm^2$ and $4.36\pm4.11N/cm^2$, respectively,. There was a significant decrease after training rather than that before (p<0.05). The scapuar alignments and weight bearing data on the standing position were grouped around the average (to central point) in the distribution graph. Conclusion: These findings suggest that the symmetrical scapular alignment can serve as an effective means of improving the weight bearing ability of hemiplegic patients.

This study is research for effect of the involved lower limb weight bearing training on symmetrical weight supporting rate improvement by practicing involved lower limb weight bearing training of three weeks period to improve standing equilibrium problem with asymmetric weight supporting rate of hemiplegia. In result of the study, it has shown that P-value incase of involved supporting rate is lower than level of significance $\alpha$<.05 and mean improvement rate of experienced group is higher in comparison with controlled group and experienced group. In changing quantity of involved maximum supporting rate, P-value is .26 and higher than level of significance $\alpha$<.05, and so it did not show significant difference statistically. But in case of experienced group between pre and post-test, involved side supporting rate and involved side maximum supporting rate showed significant improvement in all. In comparison of relative characteristic training effect difference, it was shown that train-learning effect on case of 40-60 years old, hemorrhagic patient and standard body bun of patient is valuable, which showed significant improvement in case of paralytic side and disease period, it did not show significant difference on excercise learning effect in two above cases. In the above result, we can say that continuous weight bearing training on the involved lower limb for three weeks period help improve the involved side supporting rate of hemiplegia. Accordingly, the weight bearing training on the involved lower limb is training method that patient can easily train with simple guidance of therapists, without being special expensive equipment. Furthermore it can be helpful to establish home therapeutic plan for hemiplegia through education of a patron.

Weight bearing training on the involved leg is impotant for ambulation and activities of daily living in ambulatory hemiplegic patients. Traditionally, physical therapists have relied on exercise therapy and subjective evaluation. The goal for this study was to measure lower extremity weight distribution in standing with ten hemiplegic pations(M:8, F:2) and to determine the traing effect on symmetrical standing posture using a "Limloader". The Limloader is a machine designed for training symmetrical weight bearing posture. The results showed that the ability to keep the center of gravity within the limits for balance was improved significantly but the ability to adjust weight bearing on the involved leg was not (p<0.05). This study demostrated that hemiplegics can improved their symmetrical weight bearing ability using sensory biofeedback.

The purpose of this study was to investigate the effects of a task-oriented approach on weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement in 18 chronic stroke patients. Both groups were received neurodevelopmental treatment for 30 min/day and then the experimental group ($n_1$=9) followed additional a task-oriented approach (sit-to stand training with controlled environment) and the control group ($n_2$=9) followed a passive range of motion exercise for 15 min/day, five days/week, for four weeks. Weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement were measured before and after four weeks of training. There was significantly improved weight-bearing distribution of the paretic leg during sit-to-stand movement in the experimental group compared with that of the control group after four weeks of training (p<.05). But electromyographic activities of the quadriceps and the tibialis anterior of the paretic leg were not significantly different (p>.05). Thus, it is necessary to apply a task-oriented approach to improve the weight-bearing distribution of the paretic leg during sit-to-stand movement in chronic stroke patients.

The objective of this study was to identify the effects of weight-transfer training on the weight bearing distribution and gait patterns of hemiplegic patients through visual and auditory feedback using a limb load monitor. The subjects of this study were 18 hemiplegic patients who had been hospitalized or were visited out-patient department of the Rehabilitation Hospital, College of Medicine, Yonsei University, from January 5, 1995 through March 15, 1995. Pre-and post-training changes in gait patterns were measured using ink foot prints as well as by recording weight bearing distribution using a limb load monitor. The data were analyzed by the repeated measure one-way ANOVA and paired t-test. The finding were as follows: 1. Prior to the training, 18 subjects bore more weight on the sound leg(61.6 %) than on the affected leg(38.4 %). 2. Posterior to the training, the average percentage of weight bearing on the affected leg increased significantly from 38.4 % prior to training; to 46.0 % immediately after training; 45.7 % after a 30 second delay; and 45.3 % after a 60 second 3. The difference in gait patterns between pre- and post- training was statistically significant, with an increase in gait velocity to 3.65 cm/sec post-training; an increase in stride length to 5.37 cm on the affected side; 4.77 cm on the sound side; and a narrowing of the base of support to 1.19 cm. In conclusion, hemiplegic weight-transfer training using visual and auditory feedback with a limb load monitor was found to be enhancing symmetrical standing posture, and simultaneously improve gait patterns.
