The purpose of this study was to compare the effects of treadmill walking in underwater and overground which affects gait and physical function of people who have had a stroke. Twenty people after a stroke who have become hemiplegic over 6 months were participated. Participants were divided into two groups: underwater treadmill group(UTG) and overground treadmill group(OTG). The intervention was done 4 times per weeks for 6 weeks and 1 session lasted for 30 minutes. Gait and physical function elements were measured at baseline, at the middle(3 weeks) and at the end of the intervention(6 weeks). For the elements of gait, walking velocity, affected stance phase, affected weight bearing were assessed. For the elements of physical function, Short Form 8(SF-8) health survey was used. The result of this study showed that both groups improved similarly in walking velocity. However participants in UTG improved more than those in OTG in affected stance phase(p<.05), affected weight bearing(p<.05) and emotional aspect(p<.001). Based on the results of this study, it can be suggested that treadmill walking both in underwater and on the ground can be effective in improving hemiplegic gait and physical function of people who have had a stroke. The result also suggest that the underwater treadmill exercise can be more effective than overground treadmill in restoration of gait in people after stroke.

Background: This study aimed to investigate the effects of noninvasive electrical stimulation combined with trunk stabilization exercise on balance and fall risk in patients with stroke. Methods: Twenty-two patients with stroke were enrolled in the study and randomly divided into experimental and control groups, each with 11 patients. noninvasive electrical stimulation combined with trunk stabilization training was applied to the experimental group, and sham noninvasive electrical stimulation combined with trunk stabilization training, to the control group. Both groups were treated for 6 weeks, five times a week for 30 min each time; the balance and fall risk of patients with stroke were measured before and after treatment, and the changes in the two groups were compared and analyzed. Results: The experimental group's left and right weight-bearing indices (affect and non-affect sides) and the front and rear weight-bearing indices, were significantly improved (p<.05, p<.001). when the changes in balance ability between groups were compared before and after treatment. The total fall efficacy score in the experimental group was substantially lower than that in the control group when the changes in fall efficacy score were compared between groups following treatment (p<.001). Conclusion: The improvement in balance and fall risk in patients with stroke can be attributed to using noninvasive electrical stimulation in combination with trunk stabilization training. This clinically helpful treatment method for patients with stroke warrants further promotion and implementation in the clinic.

Purpose: This study was conducted in order to investigate the exercise limit that may occur depending on changes in postural alignment by examining the significance of postural alignment changes, foot pressure, and balance of patients with stroke. Methods: In this study, 50 patients diagnosed with a stroke were selected as subjects. Imbalance of postural alignment of the trunk, pelvic tilt of trunk rotation of the body, angle of kyphotic curving of the thoracic, and angle of lordotic curving of the lumbar vertebra were measured. Foot pressure was examined by measuring average pressure and weight bearing. Balance was examined by measuring the center of pressure and limit of stability. Results: The significance of postural alignment, foot pressure, and weight bearing of the non-paretic side was examined. In addition, the significance between postural alignment and balance was examined. Conclusion: It is thought that limits of foot pressure and balance in the standing position can be caused by postural alignment. Thus, both a therapeutic intervention program and postural alignment training should be provided together in order to improve the function of patients with stroke.

Background: Pes planus, or flat foot, causes lower limb malalignment and foot pain during walking or exercise. Therefore, a highly reliable evaluation method to accurately diagnose flat feet is necessary. This study investigated the intra-and inter-rater reliability of the navicular drop test in different postures. Design: Cross sectional study. Methods: Forty healthy volunteers performed the navicular drop test in three different combinations of non-weight-bearing and weight-bearing postures (standing/standing, sitting/sitting, and sitting/standing). Two examiners alternately performed the measurements five times in each subject, and in each posture. Significant differences in measurements were obtained among the three postures, with the highest navicular drop being observed in the sitting/standing posture. Results: Inter-rater reliability was high in the sitting/standing and sitting/sitting postures. Intra-rater reliability was high in all three postures. In the sitting/sitting and sitting/standing postures, large navicular drop values and high inter- and intra-rater reliability were observed. Conclusion: Therefore, the sitting/standing and sitting/sitting postures are recommended for use in navicular drop tests to diagnose flat feet.

A 6-year-old, 36.5 kg castrated male Golden Retriever presented for revision surgery for left total hip replacement. The patient underwent removal of the cup and head implants due to unmanageable prosthetic hip dislocation, despite revision surgery. On physical examination, the dog showed persistent weight-bearing lameness after exercise of the left hindlimb with mild muscle atrophy. Radiographic examination revealed dorsolateral displacement of the femur with a remnant stem and bony proliferation around the cranial and caudal acetabulum rims. The surgical plan was to apply the dual mobility cup to increase the range of motion and jump distance to correct soft tissue elongation and laxity caused by a prolonged period of craniodorsal dislocation of the femur. The preparation of the acetabulum for cup fixation was performed with a 29-mm reamer, and the 29.5-mm outer shell was fixed with five 2.4-mm cortical screws. The head and medium neck of the dual-mobility system were placed on the cup, and the hip joint was reduced between the neck and stem. The dog exhibited slight weight bearing on a controlled leash walk the day after surgery. The patient was discharged 2 weeks postoperatively without any complications. Six months postoperatively, osseointegration and a well-positioned cup implant were observed, and the dog showed excellent limb function without hip dislocation until 18 months of phone call follow-up.

Objectives : Osteoporosis is generally occurred in old age, especially postmenopausal women therefore, it is relatively overlook osteoporosis in children, but the authors have paid attention to bone density in children because maximizing peak bone mass of childhood is advocated as a way to prevent osteoporosis and environmental factor of childhood play role in the regulation of bone density. the present study was performed to measure bone density of children and to assess the influence of age, sex, body size, exercise, weak symptoms on bone density during the period of bone growth. Methods : We have measured bone density of calcaneus bone in 283 children (male 144 female 139, ranged from3 to 18) who visited in growth clinic of Pediatrics, Dongguk University Bundang Oriental Hospital, using quantitative ultra sound densitometry and they were divided into 3 groups by age(3-10, 11-15, 15-18 years). Pearson's correlation was used to assessed the influence of age, body size and Student's t-test was used to detect differences in sex, exercise, weak symptoms between the groups on bone density Results : The bone density correlated with age, height, weight, body mass index in this study. Bone density were significantly higher in males than in female. Digestive weak children's bone density were lower than normal children. Conclusion : Weight-bearing exercise and food rich in nutrition are necessary to increase maximizing peak bone mass in children.

Objective: To investigate the physical appearance and therapeutic changes that occur with the performance of Schroth exercise in patients with scoliosis. Design: Randomized controlled trial. Methods: Fifteen subjects with maximum curvature of the lumbar who were diagnosed with idiopathic scoliosis had volunteered to participate in the study. Eight subjects were included in the experimental group where they performed the Schroth Therapeutic Exercise and the other seven were included in the control group. The experimental group underwent 2 hours of weekly treatment for 12 weeks, while the control group did not during the same period based on the decisions of patients or guardians. The Mann-Whitney rank test was carried out to compare the treatment results of the two groups, and the comparison within the group was done by Wilcoxon signed-rank test. The vertebral rotation angle (VRA) was by Scoliometer, and difference of rotated and curved portion volume (DV) between both sides on the major curvature portion measured by 3D human body scanning system. Results: In the experimental group, 12 weeks of Schroth exercise therapy has significant improved in correction rate (CR) in Cobb's angle (CA), VRA, and DV between both sides on the major curvature portion (p<0.05), while significant differences were not found between the groups regarding weight bearing difference in both feet (WD) and DV (p<0.05). Conclusions: Schroth exercise performance showed significant changes in the patient's therapeutic changes (CA, VRA), but the physical appearance (DV, WD) was not significant, indicating that external changes in the treatment goal setting are more difficult goals to achieve.

Purpose: To analyze the outcome of distal tibia fracture treated with the Distal Tibia LCP with combination of interfragmentary screw. Materials and Methods: Between January 2008 and March 2012, data of 34 patients with fracture of distal tibia treated with the Distal Tibia LCP with or without combination of interfragmentary screws were reviewed. There were 17 males and 17 females with an average age of 51.8 years (range, 18~77 years). Radiographic union time and time from surgery until ability to full weight bearing were measured and compared. Callus index was measured as quotient of callus thickness and diameter of corticalis both in AP and sagittal direction. Results: 12 fractures were treated with interfragmentary screws and 22 fractures were treated with bridging plate alone. In interfragmentary fixation group, time to full weight bearing was 14 weeks versus 15.75 weeks without screw. Callus index at bearing was not significantly lesser in patients with screw compated with those without, but callus index difference at posterative 4weeks was sigficant. Radiologic union time was 11.3 weeks in interfragmentary fixation group and 12.58 weeks without screw. Conclusion: The osteosynthesis with the Distal tibia LCP with combination of interfragmentary screw seems to be more stable in postoperative 4weeks than Distal tibia LCP alone, expecting to earlier ROM exercise and rehabilitation.

Inpatients are mostly occupied in bed with restricted activity, nearly all patient populations are at risk for the occurrence of skeletal muscle atrophy due to decreased level of activity. Restriction of mobility is far greater in pediatric patients compared with adult patients since almost all the activities of daily living is performed by parents or caregivers. It could be assumed that pediatric patients are more vulnerable to skeletal muscle atrophy than adult patients, however, there have been no attempts to reduce the atrophy of developing muscle. Therefore it is important to determine the effect of exercise in developing muscle during decreased activity. The purpose of this study was to determine the effect of periodic weight support during hindlimb suspension on the mass and cross-sectional area of Type I and II fibers in developing soleus(Type I ) muscle. To examine the effectiveness of periodic weight support activity in maintaining mass and fiber size. the hindlimb of young female Wistar rats was suspended(HS) and half of these rats walked on a treadmill for 45min / day(15min every 4h) at 5m / min at a 15 grade(HS-WS). After 7days of hindlimb suspension, soleus wet weight was 28. 57% smaller and relative soleus weight was 28. 21% smaller in comparison with con-trol rats (p〈0.05) Soleus wet weight and relative soleus weight increased by 67.72% and 71.43% each with periodic weight support activity during hindlimb suspension (p〈0.01, p〈0.005), moreover soleus wet weight and relative soleus weight of the HS -WS rats were greater than those of the control group. No change was observed in fiber type percentage of the developing soleus muscle after 1 week of hindlimb suspension plus weight support activity. Type I and II fiber cross-sectional areas of the developing soleus muscle were 50.45% and 43.39% lower in the HS group than in the control group (p〈0.0001), type I and II fiber cross-sectional areas of the developing soleus were 24.49% and 29.93% greater in the HS - WS group than in the HS rats (p〈0.0001), whereas Type I and II fiber cross-sectional areas of HS - WS group were less than those of the control group, The results suggest that periodic weight support activity can ameliorate developing soleus muscle atrophy induced by hindlimb suspension, even in type II fibers that would not have been expected to be recruited by this type of neuromuscular demand. Clinical experimental study is needed to deter-mine the effect of periodic weight bearing exercise on developing atrophied leg muscle based on these results.

Purpose: The aim of this study was to ascertain the effects of the lower extremity muscle strengthening exercise on balance and ambulation of children with cerebral palsy. Methods: 10 subjects who participated in this research undertook the 12-week the lower extremity muscle strengthening exercise program, which consisted of a series of mat exercises and sling exercises. The statistical significances were examined by using Wilcoxon signed-rank test, a non-parametric test, for evaluating the improvement of balance and ambulation of the subjects. In order to evaluate the correlation among the variables, Pearson's correlation coefficients were also calculated. In all statistical analyses the significance level was selected as ${\alpha}$=0.05. Results: Berg balance scale(BBS) was significantly increased after the intervention(p<.05). Percentage weight bearing(PWB) was decreased after the intervention, but there was no significant difference. Time up and go test(TUG) value was significantly decreased(p<.05). Gait velocities was increased after the intervention, but there was no significance. Stride length, step lengths of the affected side and the sound side were significantly increased after the intervention(p<.05). In the correlation analyses of the measures before the intervention, TUG had significant negative correlation to BBS and gait velocity(p<.05). Stride length, step lengths of the sound side and the affected side had significant positive correlation between themselves(p<.01). In the correlation analyses of the measures after the intervention, TUG had significant negative correlation to BBS and gait velocity(p<.05). BBS revealed significant positive correlations to stride length, step lengths of the sound side and the affected side(p<.05). Stride length, step lengths of the sound side and the affected side had significant positive correlation between themselves(p<.01). Conclusion: Based upon the outcomes as above, it is likely that the muscle strength exercises have substantial effects on balance and ambulation of children with cerebral palsy. Thus various lower extremity muscle strengthening exercise programs are required to be studied and developed in order to contribute to functional improvements of children with cerebral palsy.
