Objective: Kinesio tape has been applied to the ankle to improve balance and gait. Stroke patients show abnormal gait patterns due to foot drop. This study aimed to determine the effects of ankle balance taping which to support the ankle joint on balance and gait in patients with chronic stroke. Design: A randomized controlled trial. Methods: Twenty-four chronic stroke patients were selected and randomized into experimental group (n=12) and control group (n=12). The experimental group applied kinesio taping three times a week for three weeks, and the control group applied placebo taping for the same amount of time. To evaluate the effectiveness of the treatment, the subjects' walking ability, static balance, and dynamic balance were assessed before and after the experiment. Gait speed and spatiotemporal gait ability were measured to examine walking ability, postural sway velocity and velocity moment for static balance, and Timed-Up and Go test and Berg Balance Scale were conducted to check dynamic balance. Results: The experimental group showed a significant increase in walking ability, static balance, and dynamic balance in the within-group pre-post difference (p<0.05). In the between-group comparison, the experimental group had a significant difference in walking ability than the control group (p<0.05). Conclusions: Ankle balance taping can help improve gait, and this study can be used as a basis for future studies of ankle balance taping.

This study aimed to investigate the relationship between physical characteristics and walking ability in the elderly population. Subjects were 77 elderly (38 men and 39 women) who are capable of walking independently with and without walking aids. Correlation and stepwise multiple linear regression analyses were used to analyze the relationship between physical characteristics (age, gender, height, weight, body mass index, muscle mass, waist/hip ratio, heart rate, vital capacity, flexibility, maximum oxygen consumption, one-leg standing time, and strength of knee flexor and extensor) and walking velocity of subjects. Age, height, vital capacity, one-leg standing time, and strength of knee flexor and extensor showed significant correlations with walking velocity of subjects (p<.05). Further, the strength of knee flexor explained 27% of the variance, and up to 32% of the walking velocity could be explained when the strength of knee extensor were added to the model. The findings suggest that walking velocity of elderly depends on the strength of lower limb's strength and a variety of physical characteristics.

This paper deals with ZMP trajectory generation in multi step walking of IWR-III(Inha Walking Robot) Biped Walking Robot. Biped walking is realized by combining 6-types of pre-defined steps and the actual ZMP can be used as a stability index of a robot. For the good tracking of actual ZMP, desired ZMP trajectory is generated during the whole walking time not for each step. Trajectory generation is performed considering velocities and accelerations of given via points using 5-th order polynomial interpolation method. As a result, balancing joints have a more smooth and continuous motion and actual ZMP has a better tracking ability. Numerical simulator is done by MATLAB to guarantee the walking of a robot satisfying the ZMP stability.

Background: This study was conducted to investigate the effects of pressure belt during proprioceptive neuromuscular facilitation sprinter pattern training using a Thera-band on leg muscle strength and gait in stroke patients with stroke. Methods: Nine patients with stroke underwent training five times a week for four weeks, and changes in the muscle strength and walking ability of the paralyzed leg before and after training were measured. Muscle strength was measured using a Digital muscle tester, and walking ability was measured using a G-WAKER and the timed up and go (TUG) test. Results: Results showed that the quadriceps, hamstring, tibialis anterior, gastrocnemius, cadence, stride length, and stance phase significantly increased (p<.05). The swing phase, gait cycle duration, and TUG test results significantly decreased (p<.05). Conclusion: This study demonstrated that a pressure belt is a very useful tool for improving muscle strength and walking ability in patients with stroke.

Purpose: This study aimed to determine how inclined-treadmill walking training with rhythmic auditory stimulation affects balance and gait in stroke patients. Methods: Ten chronic stroke patients, admitted to B hospital in Gangwon-do between August and October 2015, were trained 5 times per week for 4 weeks; each session lasted 30 minutes. To assess balance and gait before and after the training, the timed up and go (TUG) test, Berg balance scale (BBS), six minute walking test (6MWT), and three-dimensional spatiotemporal gait ability were used to measure the relevant variables. The data were analyzed using the paired t-test, and the statistical significance level was 0.05. Results: There were significant differences in the TUG, BBS, 6MWT, gait speed, cadence, single limb support (SLS), and symmetric index (SI) before and after training (p < 0.05). Conclusion: The results showed that the inclined-treadmill walking training with rhythmic auditory stimulation was effective at improving the balance and walking ability of stroke patients. Hearing training, using one of the basic procedures of proprioceptive neuromuscular stimulation, is considered to be an important aspect.

Objective: The purpose of this study was to investigate the effect of treadmill exercise on the posture and walking speed of chronic stroke survivors with an ankle-foot orthosis. Design: Randomized controlled trial. Methods: Twenty-four chronic persons with chronic stroke admitted to Bobath Memorial Hospital in Seongnam city were divided into two groups by random blind method. Treadmill exercise with an elastic ankle-foot orthosis was performed in the experimental group and treadmill exercise was performed in the control group. The experiment was carried out for 6 weeks, and the experiment was carried out three times a week for 20 minutes per session. To measure the effect, static balance was measured using the MTD system before and after training, and the Berg Balance Scale (BBS) was used to measure functional balance. Results: There was a statistically significant difference between the 2 groups in the BBS measurement results for confirming the functional balance (p<0.05). Also, there was a significant difference between the 2 groups in single limb support time, step time and step length (p<0.05). Conclusions: In this study, it was found that treadmill exercise with an elastic ankle-foot orthosis in persons with chronic stroke was effective in maintaining functional balance, walking ability, step length, and step time. Therefore, it is necessary to use a flexible ankle-foot orthosis with proper treadmill exercise as a method of improving balance and walking speed of chronic stroke survivors.

Purpose: Backward walking has shown positive effects on gait recovery in rehabilitation patients. It is increasingly used as an aerobic training method in rehabilitation populations, inducing more sensory and motor stimulation than forward walking. Therefore, the purpose of this study is to investigate the effects of visual stimulation during backward walking. Methods: Twenty-seven healthy adults with a visual acuity of 0.8 or higher participated in the study. To compare the effects of visual stimulation during various walking conditions among healthy individuals, the participants randomly selected cards numbered one to six and walked a distance of 10 meters. Walking ability was measured using Optogait. Results: Statistically significant differences were observed in speed, stride, and percentages of single support and contact phase during backward walking. Within eyes-closed conditions during backward walking, significant differences were found in percentages of single support, terminal stance, and contact phase. Moreover, the percentage of terminal swing significantly differed during backward walking with head turn conditions. Conclusion: Gait parameters such as speed, stride, and percentages of single support and contact phase were higher during backward walking than forward walking. These results indicate that backward walking involves multiple sensory systems and varying conditions.

PURPOSE: The purpose of this study was to determine the effect of action observation with observation type on the limits of stability and dynamic gait ability in stroke patients. METHODS: The 20 stroke patients who participated in this study were randomly divided into two experimental groups who underwent training three times a week for 4 weeks. Their balance was tested as the limit of stability with Biorescue. Their Dynamic gait ability was tested with the Dynamic Gait Index (DGI) before the intervention, and after 4 weeks. Independent and paired t-tests were used to analyze the results. RESULTS: The results confirmed the limit of stability on the moving areas of the paralyzed and non-paralyzed sides. The limit of stability and dynamic gait index measurements confirmed that the moving area showed a significant difference after the intervention in the whole movement observation group (p<.05), but the partial movement observation group showed no significant difference (p>.05). A significant difference was also noted for the comparison between the both groups after the interventions (p<.05). The functional walking ability showed a significant difference when compared to the ability before the intervention, as determined by the changes in scores obtained for the dynamic gait index (p<.05). CONCLUSION: Interventions utilizing whole movement confirm that training improves stability and functional walking ability in stroke patients with disabilities in balance and walking ability.

This study examined the gait ability and foot pressure after backward walking training in hemiplegia patients after stroke to provide evidence for the application of backward walking to the rehabilitation of those patients. Twenty hemiplegia patients hospitalized at one rehabilitation hospital were enrolled in this study, which was conducted from 23 April to 18 May, 2012. The subjects were randomized into either the experimental group or control group. The control group received general physical therapy for 30 minutes and the experimental group received 20 minutes of physical therapy and 10 minutes of backwards walking training five times a week for four weeks. The gait ability and foot pressure of both feet were measured quantitatively and compared. The results showed the weight bearing (entire foot, anterior and posterior of foot) of the paralyzed foot during the stance phase showed a significant difference (p<.05). The difference in the foot pressure of right and left feet was more significant in the experimental group than that of the control group (p<.05). Therefore, this study confirmed that backward walking training in a rehabilitation program would be helpful for improving the gait ability of hemiplegia patients after stroke.
