PURPOSE: While underwater, patients with hemiplegia experience unwanted limb flotation on their paretic side due to low muscle mass and high body fat. However, only a limited number of studies support the effectiveness of this practice. Therefore, the purpose of this study was to determine how the balance and walking abilities of patients with hemiplegia due to stroke were affected by wearing an aquatic cuff on their ankles during underwater treadmill walking. METHODS: Twenty stroke patients were divided into an experimental group comprised of 20 patients who would wear an aquatic cuff and a control group comprised of 10 patients without an aquatic cuff. Both groups underwent a six-week intervention for 30 minutes a day three times a week. To evaluate the groups' balance and walking abilities before and after the intervention, the 10 m walking test, timed up go test, Berg Balance Scale, functional reaching test, and the GAITRite system were used. RESULTS: The results of the 10 m walking test, timed up go test, differences between the left and right gait cycles, and functional reaching test showed statistically significant differences in the rates of change between the two groups (p<.05). CONCLUSION: The study results suggest that underwater treadmill training in stroke patients can be more effective when they wear an aquatic cuff on their ankles compared to wearing no aquatic cuff.

Purpose: This study was conducted to compare the effect of visual feedback training using mirror and the training without mirror on the balance in people with hemiplegic paralysis. Methods: A total of 26 stroke patients were enrolled in this study. The participants were allocated randomly to 2 groups : visual feedback training group(n=13) and control group(n=13). Both groups received PNF(proprioceptive neuromuscular facilitation) for 5 times(each 30 minutes) per week over 6 weeks period. The group, which is enrolled in visual feed back training, performed additional exercise in front of mirror for 30 minutes. The control group performed same exercise without mirror. The data was analyzed using a paired t-test and independent t-test to determine the statistical significance. Results: The visual feedback training group showed significantly increased foot pressure and total pressure compared to the control group(p<.05) and significantly decreased body sway compared to the control group (p<.05). Also, visual feedback training group showed significant increase on the Berg Balance Scale(BBS), Timed Up and Go test(TUG) compared to the control group(p<.05). Conclusion: These results support the perceived benefits of visual feedback training using mirror to augment the balance of stroke patients. Therefore, visual feedback training using mirror is feasible and suitable for stroke patients.

The purpose of this study was to determine the effect of HPAFO(Hinged Plastic Ankle Foot orthosis) and SPAFO(Solid Plastic Ankle Foot Orthosis) on standing balance and step moving in hemiplegia patients. Twenty hemiplegic patients were either inpatient or outpatient at the Rehabilitation medicine, MokPo J General Hospital and JeonJu J Medical Center from July 15, 2002 to September 15, 2002. Patients were able to ambulate independently for at least 10 meters and to stand independently for at least 10 minutes with balance measurement tool. The static balance and dynamic activity measurement was determined by SAKAI active balancer(Japan) with wearing HPAFO and wearing SPAFO. The static balance and dynamic activity analysis was analyzed by independent t-test. The results were as follows: 1. There were no significant difference in body weight bearing percent between wearing HPAFO and wearing SPAFO(p>0.05). 2. There were significant difference in whole path length between wearing HPAFO and wearing SPAFO(p<0.05). 3. There were significant difference in Effective Value Area between wearing HPAFO and wearing SPAFO(p>0.001). 4. There were significant difference in repeated functional time between wearing HPAFO and wearing SPAFO(p>0.001). 5. There were significant difference in cadence between wearing HPAFO and wearing SPAFO(p>0.001). The result of this study showed that wearing HPAFO and wearing SPAFO gave fair amount of improvement to static standing balance and dynamic movement ability of hemiplegic patients. The comparison result showed significant differences in between HPAFO and SPAHFO. The result of this study had a general limitation due to the restricted number of cases. The future study needs more detailed research and comparison with various variance between these two orthoses.

Objectives : The purpose of this paper is to examine Zhang Zihe's reinforcement method based on the theory of keeping balance(以平爲期). Methods : Based on his arguments in the Rumenshiqin and formula compositions, Zhang Zihe's reinforcement method was examined. Results & Conclusions : 1. Despite preconceptions that Zhang Zihe must have been critical of reinforcement methods due to his alliance to the offensive purgative group, in reality his criticism was not aimed at reinforcement methods entirely, but rather at warming and tonifying. 2. Zhang Zihe's criticism of warming and tonifying was based on his research of the Neijing, in which he realized the pathogenic effects of fire-heat and the side effects of warming and tonifying in clinical practice. This is a common conception among the Four Great Doctors of the Jin-Yuan period. 3. Zhang Zihe focused on eliminating pathogenic qi so that the body's qi would circulate smoothly to slowly restore the source qi. The theory of keeping balance was emphasized to achieve this goal. 4. Based on the theory of keeping balance, Zhang Zihe used various medicinals with different properties and flavors to allow for the medicinals in each of the sovereign, minister, assistant and courier positions to co-operate with each other, while using food reinforcement to restore the source qi.

Objective To elucidate the effect of a 12-week horizontal vibration exercise (HVE) in chronic low back pain (CLBP) patients as compared to vertical vibration exercise (VVE). Methods Twenty-eight CLBP patients were randomly assigned to either the HVE or VVE group. All participants performed the exercise for 30 minutes each day, three times a week, for a total of 12 weeks. Altered pain and functional ability were evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI), respectively. Changes in lumbar muscle strength, transverse abdominis (TrA) and multifidus muscle thicknesses, and standing balance were measured using an isokinetic dynamometer, ultrasonography, and balance parameters, respectively. These assessments were evaluated prior to treatment, 6 weeks and 12 weeks after the first treatment, and 4 weeks after the end of treatment (that is, 16 weeks after the first treatment). Results According to the repeated-measures analysis of variance, there were significant improvements with time on VAS, ODI, standing balance score, lumbar flexor, and extensor muscle strength (all p<0.001 in both groups) without any significant changes in TrA (p=0.153 in HVE, p=0.561 in VVE group) or multifidus (p=0.737 in HVE, p=0.380 in VVE group) muscle thickness. Further, there were no significant differences between groups according to time in any of the assessments. No adverse events were noticed during treatment in either group. Conclusion HVE is as effective as VVE in reducing pain, strengthening the lumbar muscle, and improving the balance and functional abilities of CLBP patients. Vibrational exercise increases muscle strength without inducing muscle hypertrophy.

Purpose: The purpose of this study was to investigate the effects of a neck exercise using a proprioceptive neuromuscular facilitation (PNF) neck flexion and extension pattern on body balance in a progressive range of positions (supine, prone on elbow, and sitting), on numbness in the upper extremities, and on neck flexion motions in cervical myelopathy patients. Methods: One participant who was diagnosed with cervical myelopathy participated in this study. A reversal design (A-B-A') was used. The A and A' were the baseline period (no intervention), and B was the intervention period. The intervention used a neck extension pattern with a hold-relax technique and a neck flexion pattern with a combination of isotonic techniques in the supine position. Then, neck flexion and extension patterns were applied together with a reversal technique for stabilization, followed by a neck extension pattern with a combination of isotonic techniques in the prone position on the elbows. Finally, a neck flexion and extension pattern was used with a stabilizing reversal technique, and a neck extension pattern was applied with a combination of isotonic techniques in the sitting position for 60 minutes per day, 3 times per week for 8 weeks. To measure balance, numbness, and neck motion during neck flexion, the one-leg stand test and the visual analogue scale were used. Results: The right and left one-leg stand tests showed increased balance ability in the intervention phase. Upper extremity numbness was decreased in the intervention phase, and neck flexion motion was increased in the intervention phase. These increases were maintained after the intervention (Baseline II). Conclusion: These results suggest that a neck exercise using a PNF neck pattern with additional techniques in a progressive range of positions has a positive effect on cervical myelopathy patients for balance, numbness, and neck motion.

Objective: To compare the postural control between non-specific chronic low back pain (NSCLBP) subgroups and healthy people during dynamic balance performance using a modified Star Excursion Balance Test (mSEBT). Design: Cross-sectional study. Methods: Eighteen NSCLBP subjects (9 active extension pattern [AEP], 9 flexion pattern [FP]), and 10 healthy controls were enrolled in this study. All subjects performed mSEBT on their dominant leg on a force plate. Normalized reach distance and balance parameters, including the center of pressure (COP) displacement and velocity, were recorded. Results: There were significant differences in mean reach distances in both posterolateral and posteromedial (PM) reach directions between AEP and healthy subjects (p<0.001) and between FP and healthy subjects (p<0.001). However, there were no significant differences among the three groups in the anterior reach direction. Also, the results showed no significant differences in mean COP variables (velocity and displacement) between pooled NSCLBP and healthy subjects. However, the subjects were reclassified into AEP, FP and healthy groups and the results showed a significant difference in mean COP velocity in the PM direction between AEP and FP subjects (p=0.048), and between AEP and healthy subjects (p=0.024). Conclusions: The findings in this study highlight the heterogeneity of the individuals with NSCLBP and the importance of identifying the homogenous subgroups. Individuals with AEP and FP experience deficits in dynamic postural control compared to healthy controls. In addition, the findings of this study support the concept of the Multidimensional Classification System.

Purpose: This study investigated the effect of the augmented reality (AR)-based knee joint short period exercise program and used a motion analyzer with a 3D camera to determine the range of motion and dynamic balance and further investigate the effects of therapeutic exercise on patients. Methods: This study used AR-based motion analysis and a Y-balance test to measure the range of motion (ROM) of each joint: the hip joint and the knee joint. After the measurements, an exercise program was applied to the subjects, using the knee motion program function, and the muscles of the quadriceps femoris and the hamstring were stretched or strengthened. Results: Our results showed knee joint extension at the dominant hip joint flexion position. While there was no significant difference (p>.05) at this position, there were significant differences in the non-dominant hips, unbalanced knee joint flexion, and superior knee joint flexion (p<.05). The Y-balance test using the non-dominant leg supported by the dominant legs showed that the absolute reach was $69.70{\pm}7.06cm$ before the exercise, and the absolute reach after the exercise was $77.56{\pm}6.09cm$ (p<.05). Conclusions: There was a significant difference when the movement of the lower limbs supported the superior limbs, and a significant difference was found in the ROM when the non-dominant side supported the dominant side. Therefore, the AR-based exercise program improves the balance of the human body and the range of motion of the joints, and research that aims to improve patients abilities should continue.

종류가 다른 채소 3종을 임의로 선정하여 마우스의 Na, K, Ca, Fe, Cu, Zn, Mg 밸런스에 어떠한 영향을 미치며, 또한 채소의 종류나 양, 사육기간이 영향을 미칠 수 있는 요인인지 조사하였다. 실험동물은 8주된 SPF계 마우스 130마리를 사용했으며 평균 체중은 $29{\sim}38g$이었다. 마우스 10마리를 대조군으로, 나머지 120마리를 3군으로 나누어 이를 다시 두군으로 나누어 한마리씩 분리 사육시켰다. 대조군은 물(2차 증류수)과 식이를 제한없이 주고 다른군은 물 대신 임의로 선정한 채소 3종(당근, 껍질콩, 호박)으로 대체하고 각군 20마리 중 10마리는 1주(단기간) 10마리는 2주(장기간) 사육시켜 실험 완료일 까지의 실험식이 섭취량이 대조군과 유의적인 차가 없는 마우스만을 실험대상으로 하였다. 또한 이들 채소의 양에 따라서 당근대량군(12마리), 당근소량군(10마리), 껍질콩대량군(11마리), 껍질콩소량군(9마리), 호박대량군(10마리), 호박소량군(14마리)으로 분류하였다. 체중증가는 대조군에 비하여 껍질콩대량군이 높게 나타났으며, 식이 효율은 대조군에 대한 차이가 없었다. 분변과 요량은 채소 급여에 의하여 증가하였다. 체중증가와 식이효율, 분변과 요량에는 채소의 종류나 양, 사육기간등이 작용인자로는 확인되지 않았다. 무기질 섭취량은 대조군에 비하여 Na, Ca, Fe, Cu가 호박대량군에서 가장 낮게 나타났고, K는 당근대량군이 가장 높게 나타났으며 Zn, Mg는 껍질콩대량군에서 가장 높게 나타났다. Na, K, Ca, Fe, Cu, Zn, Mg의 흡수율과 밸런스는 대조군이 플러스의 균형을 나타내는데 반하여 채소 급여군은 모두 마이너스의 균형을 나타내었다. 채소의 종류, 양, 사육기간이 Na, K, Ca, Cu, Zn의 섭취량에, Cu, Zn의 흡수율에, K, Cu, Zn 평형에 각각 영향을 미치는 요인인 것으로 확인되었다. K, Zn, Mg는 대조군에 비하여 실험군의 섭취량이 증대 했음에도 불구하고 흡수율은 마이너스이였다.
