Purpose: The purpose of this study was to compare the effects of the FES-gait with augmented feedback training to the FES alone on the gait and functional performance in individuals with chronic stroke. Methods: This study used a pretest and posttest randomized control design. The subjects who signed the agreement were randomly divided into 12 experimental groups and 12 control groups. The experimental groups performed two types of augmented feedback training (knowledge of performance and knowledge of results) together with FES, and the control group performed FES on the TA and GM without augmented feedback and then walked for 30 minutes for 40 meters. Both the experimental groups and the control groups received training five times a week for four weeks. Results: The groups that received the FES with augmented feedback training significantly showed a greater improvement in single limb support (SLS) and gait velocity than the groups that received FES alone. In addition, timed up and go (TUG) test and six minute walk test (6MWT) showed a significant improvement in the groups that received FES with augmented feedback compared to the groups that received FES alone. Conclusion: Compared with the existing FES gait training, augmented feedback showed improvements in gait parameters, walking ability, and dynamic balance. The augmented feedback will be an important method that can provide motivation for motor learning to stroke patients.

Purpose: This study compared the walking ability of chronic stroke patients following either treadmill training with knowledge of the result (KR group) or treadmill training with knowledge of the performance (KP group). Methods: Nineteen patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a KR group (10 patients) and a KP group (9 patients). They received 30 minutes of neuro-developmental therapy and treadmill training 30 minutes, five times a week for three weeks. The gait parameters were measured before and after training using the Optogait system. Results: After the training periods, the KR group showed significant improvement in gait speed, cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait assessment compared to the KP group (p<0.05). Conclusion: The results showed that treadmill training with KR was more effective in improving the gait speed and cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait ability than the treadmill training with KP. Therefore, to improve the walking ability of stroke patients, it is necessary to consider treadmill training with KR. If it can be combined with conventional neurological physiotherapy, it would be an effective rehabilitation for stroke patients.

The purpose of this study was to determine the effect of gait initiation training on gait and center of pressure (CoP) during gait initiation in stroke patients. Twenty-three subjects were randomly assigned to either an experimental group (EG) or a control group (CG). The EG received gait initiation training with increased CoP posterior distances the maximum the rear on gait training. The CG received general gait training. Both groups received training three times a week over a period of four consecutive weeks. The figures for CoP distances the maximum the rear, CoP distances time the mover the maximum the rear, the Tinetti Performance-Oriented Mobility Assessment (POMA), and gait velocity were recorded both before and after the training sessions for both groups. The EG's results for CoP distances the maximum the rear, CoP distances time the mover the maximum the rear, and POMA improved after training (p<.05). In terms of the rate of change of CoP distances the maximum the rear, the EG demonstrated a significantly higher increase (p<.05) than did the CG. The results of this study suggest that increased CoP distances the maximum the rear affect the gait initiation and gait performance of stroke patients. Further studies with a larger sample size are necessary to verify the accuracy of the results of this study.

Purpose : Many researchers have attempted to identity the reliability used in clinical examination of balance and gait performance for individuals of hemiparetic stroke. The study aims to evaluate whether the reliabilities of three popular clinical measures of balance and gait performance was consistency regardless of applicate experience of those clinical measures compared with previous studies for persons with hemiparetic stroke. Methods : A total of three hemiparetic stroke populations and twenty-six physical therapists were recruited from Glory hospital, Inchen, Korea in this study. The three clinical measures, involving Berg balance test (BBT), dynamic gait index (DGI), and Tinetti performance-oriented mobility assessment (POMA), were assessed in two sessions that were seven days apart. Results : The POMA was showed a good intrarater and interrater reliabilities in people with hemiparetic stroke regardless of measure's experience in clinical field. However BBT and DGI were showed below moderate intrarater and interrater reliabilities. Conclusion : The POMA could be a reliable measure to evaluate functional postural stability and gait performance in hemiparetic stroke patients compared with other two clinical measures regardless of measure's experience of physical therapists.

Purpose: Walking in the dual-task condition is a critical skill for hemiplegic patients to live in real-life situations. The purpose of this study was to compare the effect of dual-task gait training and general gait training on gait parameters and cognitive function in patients with chronic stroke during dual-task walking. Methods: The study included 23 patients with chronic hemiparetic stroke who were randomly divided into experimental (dual-task gait training) and control (general walking training) groups. The 11 subjects in the experimental group and nine subjects in the control group received dual-task gait training (walking while handling a ball, crossing obstacles, picking up various objects, and problem solving simple cognitive tasks and general over-ground gait training, respectively, for 30 minutes per day 5 days per week for 4 weeks. Spatiotemporal parameters and cognitive tasks in the dual-task gait condition were measured. Statistical analysis of the changes between the pre- and post-intervention measurement variables was performed using ANCOVA. Results: In the gait condition under cognitive tasks, the changes pre- and post-intervention in gait velocity, stride length, double support limb, and step symmetry were significantly greater in the dual-task gait training group; however, the dual-task gait training group showed no significant improvement compared to the general gait training group in terms of the assessment of cognitive tasks. Conclusion: The findings suggest that dual-task gait training may be beneficial for walking ability in dual-task walking condition.

PURPOSE: Robotic gait training is being used increasingly to improve the gross motor performance and gait speed. The present study examined the effectiveness of a novel end-effector type of robotic gait training (RGT) system on standing, walking, running, and jumping functions, as well as the gait speed in children with spastic cerebral palsy. METHODS: Eleven children with spastic cerebral palsy Gross Motor Function Classification System (GMFCS) levels I-III (6 males; age range, 15.09 ± 1.44 years) were examined. They underwent 24 sessions (30 minutes/sessions, one time/day, three days/week for eight consecutive weeks) of RGT. The Gross Motor Function Measure-88 D domain (GMFM D), and GMFM E were assessed with a pretest and posttest of RGT. The setting was a one-group pretest-posttest design. RESULTS: A comparison of the pre-test and post-test show that the outcomes in post-test of GMFM D (p < .01), GMFM E (p < .05), and 10MWT were improved significantly after RGT intervention. CONCLUSION: The present study provided the first evidence on the effects of an eight-weeks RGT intervention in participants with spastic CP. The outcomes of this clinical study showed that standing performance, locomotion function, and gait speed increased in after 24 sessions of the end-effector RGT system in children with spastic cerebral palsy.

Background: Gait analysis is an important measurement for health professionals to assess gait patterns related to functional limitations due to neurological or orthopedic conditions. The purpose of this study was to investigate the reliability of the newly developed portable gait analysis system (PGAS). Design: Cross-sectional design. Test-retest study. Methods: The PGAS study was based on a wearable sensor, and measurement of gait kinematic parameters, such as gait velocity, cadence, step length and stride length, and joint angle (hip, knee, and ankle) in stance and swing phases. The results were compared with a motion capture system (MCS). Twenty healthy individuals were applied to the MCS and PGAS simultaneously during gait performance. Results: The test-retest reliability of the PGAS showed good repeatability in gait parameters with mean intra-class correlation coefficients (ICCs) ranging from 0.840 to 0.992, and joint angles in stance and swing phase from 0.907 to 0.988. The acceptable test-retest ICC was observed for the gait parameters (0.809 to 0.961), and joint angles (0.800 to 0.977). Conclusion: The results of this study indicated that the developed PGAS showed good grades of repeatability for gait kinematic data along with acceptable ICCs compared with the results from the MCS. The gait kinematic parameters in healthy subjects can be used as standard values for adopting this PGAS.

Objective: This study was conducted to investigate the effects of resistant exercise on the gait performance of a patient with systemic lupus erythematosus (SLE) patient. Design: A case study. Methods: A 30-year-old male adult who had been diagnosed with systemic lupus erythmatosus (SLE) in April 2013, right middle cerebral artery infarction, and with left hemiplegia agreed to participate in this case study. Patient was unable to walk due to being affected with adynamia. Due to developing necrotizing vasculitis on the left lower extremity, patient underwent a myotomy on the left thigh. The patient was trained with a progressive resistant exercise program for 8 weeks. An intensity of 15 RM was used for the resistant exercises and the resistance level was increased progressively in order to improve the muscle power of the patient. Methods used to increase resistance included changing positions, providing mechanical resistance instead of manual resistance, transitioning from open kinetic chain to closed kinetic chain exercises, and changing the colors of the theraband to those with increase level of resistance. Outcome measures included the 5-repetition sit-to- stand test (5RSST), Timed Up & Go (TUG), and 10-meter walk test (10MWT). In addition, the GAITRite was used to assess the spatio-temporal gait variables, including gait speed, cadence, stride length of the left side, and double limb support pre and post-intervention. Results: The patient was able to perform sit-to- stand after two weeks of performing the resistant exercises. The patient was able to walk after 4 weeks, and the patient's overall gait performance had improved after 8 weeks. All of the variables had improved after each week. Conclusions: The results of this case study may be used to enhance future efforts to objectively evaluate resistant exercises during gait performance in persons affected by SLE.

Background: This study examined the effects of adding fibular repositioning taping (FRT) to ankle mobilization with movement taping (AMT) on the ankle range of motion (ROM), balance, and gait performance in patients with chronic stroke with limited ankle dorsiflexion. Methods: The participants were randomized into the control (n=15) and AMT+FRT groups (n=15). The control groups applied only non-elastic taping on the affected ankle, and the AMT+FRT groups also applied non-elastic taping to the inferior tibiofibular joint. Both groups performed treadmill walking for 10 minutes. The ankle dorsiflexion passive ROM, balance, gait velocity, and cadence were measured before and after the intervention. Results: Both groups showed a significant difference after the intervention in the dorsiflexion ROM (p<.01), balance (p<.01), and gait performance (p<.01). On the other hand, no significant difference was observed between the two groups (p>.05). Conclusion: AMT improved ankle dorsiflexion passive ROM, balance, gait velocity, and cadence in patients with chronic stroke, but there was no difference between the two groups. Therefore, the addition of FRT to AMT does not influence the ankle dorsiflexion ROM, balance, and gait performance in patients with chronic stroke.
