The purpose of this study is to identify how postural mechanics affects postural control on balance and stability by using frequency analysis technique from the kinematic data acquired during the one leg standing posture. For this purpose, the experimental group consisted of two groups, the normal group (n=6) and the national Gymnastics group (n=6). Displacement data of CoP were analyzed by frequency analysis of rambling (RM) and trembling (TR) by FFT signal processing. As a results, there was a significant difference in evaluating the stabilization index between the two groups with the eyes open and closed one leg stnading (p <.05). The cause of the difference was found to be the output of the maximum amplitude of RM (f1) and TR (f2) (p <.05). In particular, in the low frequency RM of 8-9 Hz, which is a natural frequency of signal wave involved in postural feedback feedback, the main frequency appeared to be performs the exercise mechanism of stable brain posture control. And in the high frequency TM of 120-135 Hz, it is considered that the adaptation of the reflective muscle response is minimized to minimize posture shaking. In conclusion, this study provides evidence for the intrinsic main frequencies according to the postural control ability which affects the CNS in one leg standing.

Purpose: The primary purpose of this study was to investigate the effects of cervical stabilization exercise (CSE) on hamstring flexibility in patients with neck pain. A secondary purpose of this study was to investigate the effects of cervical range of motion (CROM) and craniovertebral angle (CVA). Methods: This study was a single-blind, randomized, comparative trial. Twenty patients were allocated into either the cranio-cervical flexion exercise (CCFE) group or the CSE group. Before and after the intervention, we measured straight leg raise (SLR), popliteal angle (PA), CROM, and CVA in the sitting and standing positions. Fisher's exact test, the Mann-Whitney test, and Wilcoxon's signed-rank test were used to analyze our data. Results: Both groups showed significant improvements in the value of SLR, PA, cervical extension, cervical rotation, and CVA in the standing position (both, p<.05) after intervention. However, only the CSE group showed significant improvements in cervical right lateral flexion (z=-2.209; p<.01) and cervical left lateral flexion (z=-2.537; p<.05) after intervention. The CSF group showed more significant improvements in SLR, PA, both cervical lateral flexions, and both cervical rotations than the CCFE group. Conclusions: The results of this study will guide future research in identifying the effectiveness of CSE. In conclusion, it can be inferred that CSE has a positive effect on SLR, PA, CROM, and CVA in the standing position in patients with chronic neck pain.

In a TV component manufacturing factory, 102 male workers aged $20{\sim}39$ years old were participated in testing for physical fitness. At the same time, worker's periodic health examination was done. Test battery for physical fitness include grip strength, trunk flexion, standing long jump, side step, single leg balance with eye close, push ups and Harvard step test. As a result of testing for physical fitness, synthetically, there is no difference between manufacturing workers and officers. By bioelectrical impedance test, it means a declining tendency to all 7 factors in the obese workers, and so, it is important for obese workers not only to promote physical fitness but also to promote health. Excluding grip strength and single leg balance with eye close, 5 fitness factors are negatively associated with degree of diastolic Blood pressure, but it is statistically not significant. And levels of sGOT & sGPT have no association with physical fitness factors.

The purpose of this study is to investigate the effects of improvement in the balance control ability of the elderly affected by Hansen's disease. We tried to compare the effects for the elderly affected by Hansen's disease with and without foot deformity. The subjects consisted of 19 patients 65 years old and older. They participated in a balance training program twice per week for 8 weeks. The following results were obtained from the training program: 1. There were significant improvements in static balance ability in one leg standing (OLS), dynamic balance ability in tandem walk (TW) and four square step (FSS) (p<.05). 2. There was a significant difference between patients with and without single-foot deformity in TW before the program (p<.05). After training, however, the difference became less significant. Also, there was not much difference between recipients with and without single-foot deformity in terms of OLS and FSS. The results of this study suggest that we need to provide training programs and rehabilitation services for the elderly affected by Hansen's disease suffering from nerve injury and disability. Furthermore, further research efforts should be made concerning rehabilitation to overcome various forms of disability.

Background : The purpose of this study is to understand the effects of ankle joint taping on balancing abilities of the elderly and to provide preliminary data on preventing falls among the elderly. Methods : In this study, 20 students(8 male, 12 female) in their 20s from D University as well as 14 elderly(4 male, 10 female) in their 70s from S community center have participated. The participants were well informed about the experiment and voluntarily participated. We measured the difference in balancing ability before and after taping between the two groups using methods such as standing on single-leg stance, TUG, and plantar pressure. Kinesio taping, a stop-watch, and the EMED-system were used as equipment along with the SPSS 12.0 program, with a significance level of 0.05, to test the difference before and after taping between the two groups. Result : First, the 70s group showed a significant increase in the dorsal flexion angle after taping. Second, the 70s group showed a significant increase in duration time of standing on one foot after taping. Third, the 70s group's TUG time was significantly shorter. Fourth, the maximum peak value for static and dynamic plantar pressure showed a significant decrease after taping; and dynamic plantar pressure area value decreased as well within significant range. Conclusion : The study has shown that taping is effective on static dynamic balancing ability of the elderly.

PURPOSE: This study was to identify the effect of a coordinative locomotor training (CLT) programs on lower extremity strength, balance, and quality of life of a cancer patients. METHODS: Subjects were instructed in CLT programs. The CLT programs consisted of sprinter and skater pattern movements performed for 30 minute three day per week for two weeks. CLT programs performed the arms and legs alternately and step up the steps on the stairs. The timed sit to stand test (TSTS) and one leg standing test (OLST) were used to test lower extremity strength. The star excursion balance test (SEBT) was used to measure balance; and the functional assessment of cancer therapy - general (FACT-G) for measuring the quality of life throughout the sessions. RESULTS: Participants showed enhanced strength compared to first baseline, as measured by TSTS (14.58%). Balance was improved compared to the first baseline as measure by OLST with open eyes (30.3%), OLST with closed eyes (114.81%), SEBT (43.76%). The increase of strength and balance were maintained in a second baseline session. There was no change for quality of life between first baseline and intervention period. CONCLUSION: These findings indicate that the CLT program is a useful exercise program that can help improve the physical activity of cancer patients who have a reluctance to move by positively affecting cancer patients' balance and leg strength.

Objective : The aim of this study was to evaluate the morphometric changes in neuroforamen in grade I isthmic spondylolisthesis by anterior lumbar interbody fusion [ALIF]. Methods : Fourteen patients with grade I isthmic spondylolisthesis who underwent single level ALIF with percutaneous pedicle screw fixation were enrolled. All patients underwent standing lateral radiography and magnetic resonance imaging [MRI] before surgery and at 1 week after surgery. For quantitative analysis, the foraminal height, width, epidural foraminal height, epidural foraminal width, and epidural foraminal area were evaluated at the mid-portion of 28 foramens using T2-weighted sagittal MRI. For qualitative analysis, degree of neural compression in mid-portion of 28 foramens was classified into 4 grades using T2-weighted sagittal MRI. Clinical outcomes were assessed using Visual Analogue Sale [VAS] scores for leg pain and Oswestry disability index before surgery and at 1 year after surgery. Results : The affected levels were L4-5 in 10 cases and L5-S1 in 4. The mean foraminal height was increased [p<0.001], and the mean foraminal width was decreased [p=0.014] significantly after surgery. The mean epidural foraminal height [p<0.001], epidural foraminal width [p<0.001], and epidural foraminal area [p<0.001] showed a significant increase after surgery. The mean grade for neural compression was decreased significantly after surgery [p<0.001]. VAS scores for leg pain [p=0.001] and Oswestry disability index [p=0.001] was decreased significantly at one year after surgery. Conclusion : Foraminal stenosis in grade I isthmic spondylolisthesis may effectively decompressed by ALIF with percutaneous pedicle screw fixation.

PURPOSE: This study examined the effects of four weeks of gaze stabilization exercises and balance training on the static and dynamic balance functions. METHODS: The study was an assessor-blinded randomized controlled trial conducted at Daegu University in South Korea. Thirty subjects who fulfilled the inclusion criteria were selected and divided randomly into three groups containing ten each. The first group received balance exercises with gaze stabilizing exercises (BGG). The second group received a balance exercise (BEG), and the third group received gaze-stabilizing exercise (GEG). Each group exercised for 40 minutes, three times a week for four weeks. The subjects were asked to complete the following static balance test: 1) one-leg standing test, 2) sharpened Romberg test, dynamic balance test, 3) Y-balance test, and 4) single-leg stand-squat-stand test. The static and dynamic balance were measured before and after four weeks to determine the effect of exercise on balance. RESULTS: The static (OLS and SRT) and dynamic (YBT and SST) balance tests showed significant differences in the surface and length of the three groups (p < .05), and the y-balance score effect size, 11.477 (p < .05), was improved significantly. On the other hand, the change in BGG value was larger than those of BEG and GEG, and the improvements in balance control were the most significant. CONCLUSION: After four weeks of exercise, BGG showed the best improvement in static and dynamic balance, suggesting that this specific type of gaze stabilization exercise with balance exercise may benefit healthy young adults.
