Background: The advantages of robotic therapy have recently been attempted several times in the rehabilitation of total hip arthroplasty (THA) patients. Therefore, this study also aims to report a case of how robot therapy affects the function of THA patients due to developmental dysplasia of the hip (DDH). Design: Case Study. Method: This study used the A-B-A' design. Period A is before robotic therapy, period B is robotic therapy, and period A' is after robotic therapy. The subjects performed physical therapy and occupational therapy for five days each during the baseline period A and A'. In intervention period B, robotic therapy was performed for five days along with the baseline intervention. This study was conducted for a total of fifteen days. The subjects' sit to stand (STS), timed up and go (TUG), and 10 metre walk (10MW) were evaluated. Result:: STS and TUG were significantly improved in periods B and A' compared to period A (p<0.05), and STS was significantly improved in period A' compared to period B (p<0.05). 10MW showed no significant improvement in periods B and A' compared to period A. Conclusions: This study confirmed that robot therapy was an effective intervention in improving the function of women in their 30s who underwent THA due to DDH. In the future, a study comparing the control group should be performed.

Background: The purpose of this study was to investigate the effect of brain education-based exercise and KPEM manual therapy integrated program on the sleep and quality of life of cancer patients. Design: Seventy subjects who were diagnosed with cancer and were undergoing treatment volunteered to participate in this study. All subjects used a nonequivalent control group pretest-posttest design for either the experimental group or the control group. In the final analysis, there were 25 subjects in the experimental group and 18 subjects in the control group. Methods: For 12 weeks, the experimental group performed brain education-based exercise (20 minutes) and KPEM manual therapy (50 minutes), and the control group performed basic physical therapy and autonomous exercise. For evaluation, the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K) and the quality of life index were measured after intervention using the European Organization for Research and Treatment of Cancer (EORTC-3.0Ver). Effect between groups, time effect over time, and group^*time interaction were analyzed through a pre-test before and after the 12-week intervention period, and repeated measure ANOVA after 12 weeks of the integrated program intervention. All statistical significance levels were set at α=.05. Results: The PSQI in the time effect (p=.001) and the group^*time interaction (p<.001) were statistically significant. In terms of EORTC, QL2 and PF2 were significant in time effect (p=.024; p=.021) and group^*time interaction (p=.007; p=.021), whereas in RF2, significance was only found in group^*time interaction (p=.028). In symptom indicators, time effect was the only significant factor in FA, SL, AP, and CO, respectively (p=.002; p=.028; p=.041; p =.005) and in DY, there were significant differences in the time effect (p=.016) and group^*time interaction (p=.002). Conclusion: The brain education-based exercise and KPEM manual therapy integrated program effectively improves the sleep and quality of life of cancer patients. It is considered that this exercise and therapy can be actively used as a psychological, emotional, and physically complementary physical therapy intervention to improve the quality of life of cancer patients.

Background: While agility is a critical factor in the performance of sport in the court field, due to the diversity of agility occurrences, it is generally difficult to develop by strength and conditioning training. Previous study reported the correlation with the static balance and agility. However, the correlation between dynamic balance and agility is insufficient. It is necessary to study how static and dynamic balance affect agility respectively, for agility development. Design: Cross sectional correlational study design Methods: Twenty young women participated in the study. Three tests were used : one leg stance(static balance),Y-balance(dynamic balance), side-step(agility). One leg stance measured time, Y-balance measured distance, and side-step measured number of times. Correlation between balance and agility was used by Pearson Correlation. Results: One leg stance and side steps were shown to be not correlated. The Y balance and the side step showed with a moderate positive correlation. Conclusion: Agility is a decisive factor in fast-moving sports performance, which is generally difficult to improve with muscle strength and conditioning training. Since the correlation between dynamic balance and agility was found in this study, the importance of dynamic balance was found to improve agility to promote coordination.

Hamstring flexibility is an important factor that affects muscle performance of the lower extremities and is closely associated with sports injuries. Therefore, evaluation of flexibility is important in clinical practice. Results of evaluation are determined by types of tests and cut-off values used; therefore, accurate and detailed understanding of these is necessary before examination. Although the straight leg raise and sit and reach tests are used to evaluate hamstring extensibility, structures including the nerves, fascia, and other muscles can significantly confound the results of these tests. The knee extension test is performed at 90° of hip flexion to minimize the posterior pelvic tilt that occurs during the straight leg test. The knee extension test is most recommended for selective evaluation of hamstring flexibility. The knee extension test is classified into active and passive tests. The cut-off value is usually set at 20° for the active and at 10° for the passive knee extension test. Although a strong association is observed between the two tests, the active knee extension test is preferred in clinical practice because it can be performed by a single examiner, which serves as an advantage. Age, sex, and warm-up exercise tend to affect flexibility; therefore, results should be interpreted with caution. Detailed understanding of each flexibility test is important for reliable evaluation.

Background: The purpose of this study was to identify the effects of underwater and ground proprioceptive neuromuscular facilitation lower extremity pattern exercise on trunk control and lower extremity muscle activity of chronic stroke patients. Design: Pretest-posttest design: single blind. Methods: The subjects were 28 patients (experimental group, n=14 or control group, n=14) diagnosed with chronic stroke. The experimental group performed underwater proprioceptive neuromuscular facilitation lower extremity pattern exercise. The control group performed ground proprioceptive neuromuscular facilitation lower extremity pattern exercise. Training was conducted once a day for 30 minutes, five days per week for six. Trunk control was measured using the Trunk Impairment Scale. Lower extremity muscle activity was measured using surface electromyography. Results: As a result of comparison within groups, the experimental and control group showed significant difference for trunk control after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in trunk control than the control group (p<0.05). In comparison within groups, the experimental group showed significant difference for lower extremity muscle activity after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in lower extremity muscle activity than the control group (p<0.05). Conclusion: Based on these results, underwater proprioceptive neuromuscular facilitation lower extremity pattern exercise effectively improved the trunk control and lower extremity muscle activity of chronic stroke patients.

Background: The purpose of this study was to investigate the immediate effects of ankle elastic and non-elastic taping on postural balance and gait ability in subject with stroke. Design: Cross-sectional study Methods: Twenty-seven subjects with stroke participated in this study. The subjects performed to stand quietly for 30s on the balance platform and walking test with three different ankle taping conditions. The sway length, sway area and sway velocity of center of gravity (COG) displacement was measured to assess the postural balance and the timed up and go test, 10m walking test, 6 minutes walking test was measured to assess the gait ability. Repeated measured ANOVA was used to compare the postural balance parameters and gait ability according to three different ankle taping conditions. Results: Postural balance with non-elastic ankle taping was significantly improved compared to no ankle taping and elastic ankle taping condition(p<0.05). On the other hand, gait ability with elastic ankle taping was significantly increased compared to no ankle taping and non-elastic ankle taping condition(p<0.05). Conclusion: These findings suggest that an elastic ankle taping could effect to improve the gait ability, whereas a non-elastic ankle taping could effect to improve the postural balance in subject with stroke.

Background: This study was performed to evaluate the effects of Thermal stimulation combined virtual reality training (TV) on improvement of upper extremity AROM and function in patient with chronic stroke. Design: Two groups pre-post randomized controlled design. Methods: A single-blind, randomized controlled trial was conducted with 30 chronic stroke patients. They were randomly allocated two groups; the TV group (n=15) and Virtual Reality training group (VT) (n=15). The TV group received treatment for 30 min - 15 min of Thermal stimulation, and 15 min of VR training. The VT group received 15 min of VR training. Each group performed 30 minutes a day 3 times a week for 8 weeks. The primary outcome upper extremity AROM and function were measured by a active range of motion test, Manual Function Test (MFT) and Jebsen-Taylor hand function Test (JTT). The upper extremity active range of motion was evaluated using a digital dual inclinometer. MFT and JTT were used to evaluate the hand function. The measurement were performed before and after the 8 weeks intervention period. Results: Both groups demonstrated significant improvement of outcome in muscle strength and upper extremity function during intervention period. TV group revealed significant differences in AROM and upper extremity function as compared to the VT groups (p<.05). Our results showed that TV was more effective on upper extremity AROM and function in patients with chronic stroke. Conclusion: Both groups demonstrated significant improvement of outcome in muscle strength and upper extremity function during intervention period. TV group revealed significant differences in AROM and upper extremity function as compared to the VT groups (p<.05). Our results showed that TV was more effective on upper extremity AROM and function in patients with chronic stroke.

Background: The purpose of this study was to investigate the effect of whole-body vibration stimulation training on the thickness of the transversus abdominis muscle and the balance of sitting posture in children with spastic cerebral palsy. Design: Single-subject design(A-B-A-B). Methods: The subjects of this study were 9 children with spastic cerebral palsy. The study period was 12 weeks in total, and the baseline period and the intervention period were each assigned 3 weeks. Intervention was conducted twice a week for 30 minutes.
