    Purpose:The purpose of this study was to investigate the effect of core stabilization exercise on foot pressure in the hemiplegic patients. Methods:A total of 28 subjects(n=28) who were diagnosed with hemiplegic caused by a stroke were randomly divided into bridge exercise(BX, n=14) and crunch exercise(CX, n=13) groups and each group executed the exercises 20 minutes a day, 4 times per week over an 8 week period. Foot pressure was measured on the fore,mid, and hind foot for peak pressure, and distance of center of pressure(COP). Results:The peak pressure on the mid foot for BX and CX were significantly different according to the exercise period(p<.05). Peak pressure on the hind foot of BX was significantly different according to exercise period(p<.05), however there was not in CX. The effects of each exercises period were significantly different according to pre-after 8weeks(p<.05). According to exercise period(p<.05), COP distances of BX and CX were significantly different. Conclusion:The results show that both BX and CX verified an improvement in gait ability. Especially, since we confirmed BX was attributed more to gait ability than CX. This is considered to be effective on those hemiplegic patients who need core-stabilization and gait stability.

    김현희 | Changho Song | 2011, 6(2) | pp.135~143 | number of Cited : 5
    Purpose:The purpose of this study was to investigate onset timing of vastus medialis oblique(VMO) relative to vastus lateralis(VL) the VMO/VL electromyographic(EMG) ratio according to heel height Methods:A repeated measures design was used. Fifteen healthy female college students with no known knee musculoskeletal dysfunction were recruited this study. They carried out a standardised stair acent activity under 4 conditions; barefoot, and with heel height of 1, 3, 7 cm. Muscle activity was measured by surface EMG (Myosystem 1400A, Noraxon Inc., U.S.A). Data were analysed using 1 × 4 repeated measures ANOVA. Results:Onset timing differed with heel height(p<.05). However, the VMO/VL EMG ratio was not significantly difference between conditions. Conclusion:We found that 7 cm heel height delayed in VMO onset compared with 3 cm heel height during stair ascent, but no change in the relative EMG intensity of VMO and VL as measured by th VMO/VL ratio. The findings indicate that high-heeled shoes may have disadvantages in knee stability because of delayed onset of VMO. Due to a lack of knee joint stability, wearing of high heeled shoes should be avoided

    The Effects of 3-Dimensional Lumbar Stabilization Exercise have an effect on the improvement of pain and static or dynamic balance ability in 20's age group with Low Back Pain

    김규용 | 안창식 | 김성수 | 2011, 6(2) | pp.235~246 | number of Cited : 18
    Purpose:The aim of this study is to compare and assess the effects of lumbar stabilization exercise on the balance ability of young college studets with low back pain after having performed spinal stabilization exercise by using 3-dimensional air-balance system and gym ball. Methods:The subjects of this study were 34 low back patients in their early twenties. They were divided into two groups: 3-dimensional lumbar stabilization exercise group(N=17) and gym ball lumbar stabilization exercise group(N=17). The period of the intervention was for five weeks. VAS(Visual Analogue Scale) for pain test,ODI(Oswestry Disability Index) for ADL limitation test, Tetrax system for static balance test, and Air-balance system 3D for dynamic balance test were used as evaluation tools for this study. Results:Pain showed significant decrease in both groups after having performed the experiment, but ADL limitation of the groups did not show any remarkable difference between before and after the experiment. Dynamic balance ability in the 8-directional angle comparison test significantly increased in all directions except for the backward, left-backward, and right-backward directions. As for dynamic balance ability in the 8-directional postural test, 3D exercise group showed statistically significant reduction in every direction while gym ball exercise group did not(p<.05). However, when it comes to static balance ability in the weight distribution and stability test, there was not significantly change between pre and post test in both groups. Conclusion:This study shows 3-dimensional lumbar stabilization exercise is more effective in the lumbar stabilization of coordinated movement than gym ball exercise, which may imply that 3D air-balance system can be used for the therapeutic treatment of body imbalance for patients with low back pain.
