  • Purpose: This study aimed to investigate the correlation between trunk stabilization muscle activation and the parameters of gait analysis in healthy individuals. Methods: Thirty healthy adults (15 male, 15 female) with no history of lower back pain (LBP) or current musculoskeletal and neurological injuries were studied. Trunk stabilization muscle activation (e.g., external oblique, internal oblique, transverse abdominis, erector spinae) were assessed using surface electromyography. To analyze gait, we measured temporal parameters (e.g., gait velocity, single support phase, double support phase, swing phase, and stance phase) and a spatial parameter (e.g., H-H base of support). Results: A statistically significant correlation was found between the internal oblique, transverse abdominis, and erector spinae muscle activity and gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique muscle activity and the gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique, internal oblique, transverse abdominis, and erector spinae muscle activity and the spatial parameter. Conclusion: This study demonstrated that a relationship exists between trunk stabilization muscle activation and temporal parameter (i.e., gait velocity, single support phase, double support phase, swing phase, and stance phase) during gait analysis. Therefore, the trunk's stabilizer muscles play an important role in the gait of healthy individuals.

  • Purpose: The purpose of this study will demonstrate that relationship between scoliosis and gait factor and foot weight bearing in ambulation. Methods: Subjects were 40 elementary students. A normal control group consisted of a total of 20 children without any known musculoskeletal disorders and an AIS group of 20 children with mild AIS (defined by a Cobb angle between 10 and $25^{\circ}$) were recruited. Measurements were scoliometer screening test, Cobb angle, gait parameter (rate of swing/stance phase, gait velosity), foot weight bearing (entire, fore, hind). Results: Scoliometer screening test (P = 0.000) and X-ray Cobb angle (P = 0.000) significant difference of group which was significantly higher in the AIS group. Gait parameter not showed significant difference. Forefoot weight bearing was significantly higher in the AIS group than more normal group. Conclusion: It seems that the results of weight bearing analysis in ambulation may be used in modifying rehabilitation programs for individual needs of patients with idiopathic scoliosis.

  • This paper describes the detection of spatio-temporal parameter using an accelerometer and footswitches to evaluate a symmetry and balance of hemiplegic patients. We detected gait data using a 3-axis accelerometer that mounted between L3 and IA intervertebral area and footswitches made by FSR-Sensor attached insole. To minimize the error of the gait parameters to be detected incorrectly in case of using only accelerometer, we enhancement the performance of detection by measuring an accelerometer and foots witches data at the same time. So, it was possible to detect more accurate gait parameters. As a result, we can confirm the symmetry and balance of hemiplegic patients. In the future. these results could be used to evaluate the walking ability in hemiplegic patients in clinical pratice.

  • 본 연구는 복부압박벨트가 만성 뇌졸중 환자의 안정성한계와 보행 변수에 즉각적인 효과를 알아보기 위해 실시하였다. 뇌졸중 환자 30명을 모집하여 복부압박벨트 착용 전과 복부압박벨트 착용 후 변화를 확인하였다. 측정은 균형변수인 안정성한계(limited of stability), 시공간적 보행 변수(spatiotemporal gait parameter)를 측정하였다. 복부압박벨트 착용 후 마비측, 비마비측, 전방, 후방 이동면적이 유의하게 증가하였고(p<.05), 시간적 보행 변수인 분속수(cadence), 보행속도(gait velocity), 공간적 보행변수인 보폭(stride length)이 유의하게 증가하였다(p<.05). 본 연구를 통해 복부압박벨트 착용은 뇌졸중 환자에게 균형과 보행 기능 개선에 즉각적인 효과가 있다는 것을 확인할 수 있었다. 향후 연구에서는 뇌졸중 환자의 균형과 보행 기능 개선에 효율적인 복부압박 수준과 중재기간에 대한 연구가 필요하다.

  • Purpose : The purpose of this study was to examine the gait parameter and plantar foot pressure of adults with Down syndrome(DS) during walking in order to provide data for developing evidence-based deficit or common rehabilitation strategies. Method : 15 participants with DS(12 men, 3 women; age $26.06{\pm}4.47$) and 15 healthy subjects(12 men, 3 women; age $25.33{\pm}3.43$) were matched age. They walked at self selected speeds on a GAITRite system and RS-scan system, and had the following measurements done: cadence, stride length, step width, foot angle, percent stance, percent double support, and plantar foot pressure in 10 areas of the foot. Results : In comparison of gait parameter(cadence, stride length, step width, foot angle, percent stance, and percent double support) between adults with DS and healthy subjects, there was significant differences(p<.05). Regarding plantar foot pressure during gait with or without DS, there were statisically significant differences in the area of Toes 1-5, Metatasal 1-4, Midfoot, and Heel(Medial and lateral)(p<.05). Conclusion : Our data show that DS walk with a less physiolosical gait pattern and plantar foot pressure than healthy subjects. Based on our results, DS patients need targeted rehabilitation and exercise strategies.

  • These were two main purposes of this study. The first was to research the relevance between gross motor function measurement (GMFM) and the spatiotemporal parameters of gait in children with cerebral palsy. The second was to research the relevance between gross motor performance measure (GMPM) and the spatiotemporal gait parameters. Twelve children ($6.0{\pm}1.8$ years) with cerebral palsy participated in this study. GMFM and GMPM were performed and the spatiotemporal parameters of gait were measured by using WalkWay MG-1000. There were no significant correlations between the GMFM score and the stride length, step length, step width, cadence, and velocity (p>.05). The GMPM score also had no significant correlation with the spatiotemporal gait parameter (p>.05).

  • This study was designed to understand gait pattern on the MBTI personality types by analyzing and figuring out specific charges, which includes analyzing gait parameter which was shown in walking movement. The personality types was measured by the standard MBTI(Myers- Briggs Type Indicator) test and gait analysis make used of GAITRite program. The objects of research were convenience sampled student of M College. Temporal and spatial parameters were calculated based on the MBTI personality types test using measured data, 68 items and SPSS pc/program was conducted to find out specific changes and obtainted the results as follows. There was not found significant in rate of swing phase and stance phase, step length, stride length, base of support, toe in/out between Extraversion group and Introversion group. But Extraversion group was significantly higher than Introversion group in velocity and cadence(p<.05). Sensing group was significantly more than iNtuiton group in cadence. There was not found significant in all parameter between Thinking group and Feeling group, Judging group and Perceiving group.

  • PURPOSE: The purpose of this study was to investigate the effects of observed action gait training on stroke patients. METHODS: 22 subjects were randomized into two groups. The observed action gait training performed that watched a video of normal gait before gait training and the general gait training without watching it. The experimental group(n=11) performed observed action gait training and the control group(n=11) performed general gait training. Both group received gait training for 3 times per week during 8 weeks. RESULTS: The experimental group showed significant differences in the cadence, gait velocity, stride, step, single limb support, double limb support, stride length and step length(p<.05). The control group showed significant differences only in the stride(p<.05). CONCLUSION: The observed action gait training affected coordination and weight shift, as well as symmetry of the body. Plasticity of the brain was facilitated by repetitive visual and sensory stimulation. The observed action gait training promoted the normal gait by watching the normal gait pattern. In conclusion, motor learning through the sensory stimulation promotes brain plasticity that could improve motor function, and observed action gait training indirectly identified stimulated brain activities.
