The purpose of this study was to determine the effects of weight shift training with joint mobilization on the ankle joint passive range of motion (PROM), balance capacity and gait velocity in hemiplegic patients. Fourteen subjects were randomly assigned to either the experimental group (EG) or the control group (CG), with seven subjects in each group. The EG received weight shift training with joint mobilization in the paretic leg's subtalar joint in order to increase ankle dorsiflexion. The CG received general physical therapy training. Both groups received training five times a week over a period of two consecutive weeks. The figures for PROM of ankle dorsiflexion on the paretic leg, the functional reach test (FRT), the timed up and go (TUG) test, and gait velocity were recorded both before and after the training sessions for both groups. The EG's results in gait velocity, the FRT and the TUG test improved after training (p<.05). The PROM of ankle dorsiflexion improved both in the EG and the CG (p<.05), the EG demonstrated a significantly higher increase (p<.05) than that of the CG. The results of this study suggest that increased joint mobilization positively affects balance and gait velocity of hemiplegic patients. Further studies with a greater sample size are necessary in order further prove the accuracy of the results of this study.

The purpose of this study was to determine the effectiveness of sit-to-stand training on unstable surfaces in individuals with stroke. Nineteen subjects with chronic stroke were divided into two groups: an experimental group (10 subjects) and a control group (9 subjects). They received 30 minutes of Neuro-developmental therapy (NDT) treatment, and sit-to-stand exercise for 15 minutes three times a week for four weeks. During the sit-to-stand training, the experimental group performed on an unstable AIREX balance pad, but the control group performed on a stable surface. Balance ability and weight-bearing distribution during quiet standing were measured before and after training period using the 7-item Berg balance scale-3P (BBS-3P) and the Five-times-sit-to-stand test (FTSST). In addition, the muscle strength of the knee extensor was evaluated before and after the training period. The results were as follows: 1) The weight-bearing distribution forward of the affected leg, increased significantly in the experimental group after the four-week intervention (p<.05), 2) The 7-item BBS-3P and FTSST increased significantly in the experimental group after the four-week intervention (p<.05), 3) The knee extensor muscle strength in both groups increased significantly after the four-week intervention (p<.05). In conclusion, the results of this study did not show that the sit-to-stand training on an unstable surface was more effective than on a stable surface. However, the results suggested that sit-to-stand training is effective in the balance training of stroke patients.

The Interest in disease prevention and rehabilitation is increasing depending on increase of patients with spinal. This is being developed using the spine stabilization device is being studied. So far studies have only evaluated the effect on trunk stabilization exercises but analysis of human movement patterns for active movement and passive movement did not. We assessed the muscle activity of trunk and leg muscle during passive and active tilt mode on eight tilt directions at tilt angle of $30^{\circ}$ using 3-D dynamic postural balance training system. We performed experimental study on the muscular activities of trunk muscle about rectus abdominis, external obliques, latissimus dorsi, erector spinae, and leg muscle about rectus femoris, Biceps femoris, Tibialis Anterior, gastrocnemius. As a result, muscle activation was different depending on the direction of movement and pattern. The results indicate that various patterns of spinal stabilization exercise system could be applied to an effective training of chronic low back pain patients.

Purpose: This study aimed to determine the effects of sensory feedback training of the ankle with visuoperceptual stimulation on static balance and gait functions in patients with chronic post-stroke hemiparesis. Methods: This study included 16 patients with chronic post-stroke hemiparesis. The subjects were randomly assigned toeither the experimental group (EG) or the control group (CG), with 8 subjects in each group. All the subjects received a routine physical therapy. The EG subjects received a 30-min sensory feedback training for the foot and ankle with visuoperceptual stimulation by using Tetrax Portable Multiple System. This training was conducted 3 times a week for 4 weeks. The scores of balance ability, timed up and go (TUG), and dynamic gait index (DGI) were assessed before and after the intervention. Results: In the EG, the scores of static balance, TUG, and DGI obtained afterthe intervention significantly differed from those obtained before the intervention (p<0.05). Further, in the EG, a significant difference was noted in the rate of change of all the variables when compared with those of the CG (p<0.05). However, in the CG, post-intervention score were only significantly different for DGI. Conclusion: Our findings indicate that the sensory feedback training with visuoperceptual stimulation improves balance and gait functions of patients with chronic post-stroke hemiparesis. Further studies are needed to generalize the results of this study.

Purpose: This study was to explore the effects of trunk exercise using PNF combined with treadmill training on balance and walking ability in patients with Parkinson's disease. Methods: This study included 16 patients with Parkinson's disease. Participants were randomly assigned to 2 groups: an experimental group (n=8) and a control group (n=8). All participants underwent treadmill training for 30 minutes. In addition, the experimental group (trunk exercise using PNF) and control group (conventional training) participated in a 30-minute exercise program. Both groups performed the training 5 times per week for 4 weeks. Disease severity (determined using the unified Parkinson's disease rating scale motor subscale, UPDRS-3), balance (determined using the Berg balance scale, BBS), walking speed (determined using the 10-meter walking test, 10MWT), and walking endurance (determined using the 6-minute walking test, 6MWT) were measured at baseline and after 4 weeks. Results: Pre- to post-intervention improvement was noted on all outcome measures for both groups (p<0.05). Post-intervention, there was a significant improvement in the experimental group as compared to the control group for the following measured outcomes (p<0.05): UPDRS-3 (p=0.03; 95% CI, -5.52 to -0.24), BBS (p=0.04; 95% CI, 0.59 to 6.45), 10MWT (p=0.01; 95% CI, -2.19 to -0.42), and 6MWT (p=0.04; 95% CI, 1.81 to 96.72) Conclusion: The results of this study revealed that trunk exercise using PNF plus treadmill training improves balance and walking ability as compared to conventional training plus treadmill training in patients with Parkinson's disease.

Purpose: The purpose of this study was to investigate the effects of coordinative locomotor training (CLT) on the foot pressure and balance of patients with scoliosis. Methods: This was a single-case A-B-A study involving two patients with scoliosis. The study was designed to perform repeated measurements as follows: 5 times at baseline (A), 10 times during intervention (B), and 5 times after intervention (A). The study period was 5 weeks, and the CLT program was divided into warm up, CLT program, and cool down stages, at 50 min per stage. For the primary outcome measure, Gait View AFA-50 was used to determine the foot pressure and balance ability. For the secondary outcome measure, the SRS-22 questionnaire was used to assess the quality of life of the patients with scoliosis. Descriptive statistics and visual analysis using graphs were used to compare the rates of change. Results: The results of this study showed that the foot pressure and balance ability of the two subjects improved during the intervention period and remained improved even during the baseline period. However, their quality of life did not change after the intervention. Conclusion: CLT may have a positive effect on foot pressure and balance ability in patients with scoliosis. Also, this body function improvement may have positive effects on the performance of daily activities which employ the upright position.

Purpose: Balance and walking ability are important elements of functional independence for people with stroke and are major goals in rehabilitation. These abilities require trunk performance, but most chronic stroke patients reach a plateau in their rehabilitation. Therefore, the purpose of this study was to investigate the effects of a self-training trunk program to improve balance and walking ability in people with stroke, and to suggest such a self-training program for integrated rehabilitation of people with stroke. Methods: The study recruited 7 people with stroke. The subjects performed trunk training for 30 min per day, 6 days per week, for 3 weeks. Participants were measured on the Trunk Impairment Scale (TIS), the Berg Balance Scale (BBS), the Korean Activities-specific Balance Confidence (K-ABC) scale, the Falls Efficacy Scale (FES), the Functional Gait Assessment (FGA), the 6 Minute Walk Test (6MWT) and a gait analysis to measure the training effects. Statistical analysis used the Wilcoxon signed-rank test as a non-parametric statistical test. Results: TIS was not significantly different after the self-training trunk program, but BBS (p>0.05), K-ABC, and FES were significantly improved after the training program (p<0.05). Furthermore, the 6MWT, stride/height %, and one-leg stance were significantly improved after the training program (p<0.05), but cadence, stance, and swing duration were not significantly different after the training (p>0.05). Conclusion: These results suggest that a self-training trunk program should be integrated into stroke rehabilitation to improve balance and walking ability, and further research is needed to develop the program to be more effective for chronic stroke patients.
