본 연구의 목적은 만성 뇌졸중 환자 8자 모양 경로 보행 검사(Figure-of-Eight Walk Test, F8WT)의 측정자간 절대적 신뢰도와 타당도를 알아보고자 하였다. 만성 뇌졸중 환자 36명을 대상으로 하였으며 F8WT 소요 시간의 측정자간 신뢰도는 급간내상관계수(Intra Class Coefficient, $ICC_{2,1}$)를 구하였고, 절대적 신뢰도는 측정의 표준 오차값(Standard Error Measurment, SEM)과 최저 실제 차이(Small Real Difference, SRD)를 구하였다. F8WT 소요시간의 타당도는 뇌졸중 자세 평가 척도(Postural Assessment Scale for Stroke, PASS)와 체간 장애 척도(Trunk Impairment Scale, TIS)간의 스피어만 상관 계수(Spearman Correlation Coefficient)를 구하였다. 연구 결과 F8WT 소요 시간의 측정자간 신뢰도 ICC=0.95(0.91~0.97)로 매우 높았고, SEM과 SRD는 각각 1.02점, 2.82점으로 수용할 만 하였다. F8WT 소요 시간은 PASS(r=-0.82), TIS(r=-0.85)와 유의한 상관관계가 있는 것으로 나타났으며, 뇌졸중 환자의 특이성 장애인 자세 및 체간 조절과 유의한 관련성이 있는 것으로 확인되었다. 따라서 F8WT는 만성 뇌졸중 환자의 보행 능력을 평가하는데 유용한 평가 도구로 사용될 수 있을 것이다.

For spinal flexibility measurements to be meaningful to clinicians or researchers, they must have a normative information and an understanding of how different variables affect spinal range of motion (ROM). Normal spinal ROM measurements are influenced to differing degrees by many factors. These factors include age, gender, time of day, leisure activities, previous history of low back pain, warming up, and the techniques with which normative data are collected. The additional variables of standing height, ratio of standing height to sitting height, and obesity had not been previously studied extensively and were shown to have a significant effect on flexibility in the sagittal plane. These relationship cannot be explained easily. Thus, the purpose of this study was to determine the relationship between spinal flexibility and individual factors (weight, standing height, and ratio of standing height to sitting height) that influence it. Fifteen healthy subjects between the ages of 20 and 27 years were studied. Two physical therapists measured independently the spinal forward bending ROM in the sagittal plane by Remodified Schober test and Finger-to-floor test. In order to determine the statistical significance of the result the Pearson's correlation was applied at the .05 level of significance. The results of this study were as follows: 1) Significant relationship was not identified between spinal flexibility and weight. 2) Significant relationship was not identified between spinal flexibility and standing height. 3) Significant relationship was not identified between spinal flexibility and ratio of standing height to sitting height.

PURPOSE: The purpose of this study is to investigate effects of trunk position sense through visual cue deprivation balance training in subacute stroke patients. METHODS: The subjects were randomly allocated to two groups: experimental(n=10) and control(n=10). Both groups performed balance training on sitting for 30minute after measurements. Trunk position sense test was assessed using the David back concept to determine trunk repositioning error for four movement(flexion, extension, affected side lateral flexion, non-affected side lateral flexion). Measurements on each test were assessed prior to the balance training and then immediately following the balance training. RESULTS: In comparison of the difference of the trunk position sense between groups, the experimental group decreased significantly in trunk repositioning error of flexion, extension and affected side lateral flexion than control group(p<.05). CONCLUSION: The trunk position sense of the experimental group showed more improvement after the balance training program compared to the control group, Therefore, these results suggest that visual cue deprivation training is considered an effective exercise method for individuals with subacute stroke.

Purpose: In this study, children with cerebral palsy were treated for 8 weeks using horse riding trunk proprioception, stability and posture to investigate the effect of hippotherapy in the field of physical therapy. Methods: A total of 18 subjects were divided into an experimental group treated by horseback riding and a control group. Both groups were evaluated pre- and post-treatment. Trunk proprioception was measured three times in the sitting position with their eyes and ears closed to reach the target position the angle error of the mean was calculated. Trunk stability was measured using a forceplate and the data were used to calculate the postural sway path & postural sway velocity. Posture was evaluated using the Posture Assessment Scale (PAS). Results: After hippotherapy, the experimental group showed a significant improvement in trunk proprioception, stability and posture (p<0.05), but the control group improved in posture only (p<0.05). Trunk proprioception, stability and posture was significantly different between the two groups (p<0.05). Conclusion: Eight weeks of hippotherapy is effective in improving trunk proprioception, stability, and posture. Research using this therapy should be studied further as a possible new therapeutic approach in the field of physical therapy.

PURPOSE: The purpose of this study was to investigate the effect of distance between trunk and desk on forward head posture and muscle activity of neck and shoulder muscles during computer work. METHODS: Twenty subjects who have healthy conditions were asked to perform computer work in two conditions (distance between trunk and desk was 0 and 15 cm). Forward head angle was analyzed with a SIMI motion analysis system. Surface electromyography recorded the upper trapezius and splenius capitis muscles. The significance of differences in distance between trunk and desk (0cm and 15cm) was tested by paired t-test. The alpha level was set at .05. RESULTS: The results showed that the change of forward head angle was significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. The muscle activity of upper trapezius and splenius capitis was also significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. CONCLUSION: Our study suggest that the distance between trunk and desk was should minimized for prevention of forward head posture during computer work.

Background: The purpose of this study was to find out the effect of trunk stabilization training on the self posture control efficacy, physical self-description and perception stress in high school students. Methods: 92 voluntary students (73 females, 19 males) participated in this study. They received trunk stabilization training for 40 minutes per day and a time per week during 6 weeks period. Trunk stabilization training was an approach of education in proper posture and coordination of movement. In the evaluation, the self posture control efficacy scale (SPCES) was used to measure the posture control efficacy, the physical self-description questionnaire (PSDQ) was used to measure the physical self description and the perception stress scale (PSS) was used to measure the stress. All measurement of each subject were measured before and after stabilization training. Results: The SPCES were significantly different before and after (p<.05). The PSDQ and PSS were no significantly different before and after (p>.05) but the means were increased slightly. Conclusion: Conclusionally these results suggest that the trunk stabilization training increased the self posture control efficacy and would give help to control Students themselves.

Purpose : The aim of this study is to compare the trunk muscle activities in trunk stabilization on the stable and unstable supporting surfaces using by sEMG. Methods : The subjects of this study include seventeen male. We measured sEMG activities of rectus abdominis and erector spine in subjects during trunk stabilization such as plank exercise, quadruped position, quadruped position with rising hand and foot on the stable and unstable surface. Results : sEMG activities in plank exercise was significantly higher in left rectus abdominis and left erector spine on unstable surface then stable surface (p<.05). sEMG activities of left rectus abdominis and left erector spine in quadruped position was significantly higher in unstable surface than stable surface (p<.05). In comparison with posture, Plank exercise showed a significant difference increase other postures (p<.05). Conclusion : sEMG activities of muscle in trunk stabilization was significantly higher in unstable surface than stable surface and plank exercise. So, we suggest that trunk stabilization on the unstable supporting surface and plank exercise were more effective method than stable surface to improve trunk muscles activities.

This study is performed to investigate the difference of the spinal stability system with and without low back pain. There were 9 participants with low back pain and 9 asymptomatic subjects to be recruited, they were measured thoracic and lumbar curvature, trunk muscle activation in upright sitting postures and slump sitting, back muscle endurance, and lumbar proprioception. Spinal curvature and surface electromyography of 4 trunk muscles were measured in an upright sitting postures and slump sitting in 18 subjects. The result of the study was that there were significant differences between the groups in spinal curvature (p<.05), significantly higher external oblique activity and less internal oblique in the low back pain group than the healthy subjects (p<.05), and significantly less proprioception in the low back pain group (p<.05). But there was not a significant difference between the trunk muscle endurance groups. According to the result, the low back pain group had greater thoracic extension and higher global muscle activity in the upright sitting posture and less proprioception. This study was useful to suggest postural training for normal muscle activation, selective muscle strengthening to prevent chronic deterioration, and helpful in making a treatment plan to indicate a synthetic care method that includes increasing proprioception.

Purpose : The purpose of this study was to find the effects of the transverse abdominis/internal abdominal oblique (TrA/IO), multifidus (MF) muscles while stabilization exercise was performed in a four-point kneeling position on the unstable surface. Methods : Twenty healthy adults volunteered to participate in this study. Each subject was instructed regarding maximum voluntary isometric contractions (MVIC) and stabilization exercise in four-point kneeling on the unstable surface. While MVIC and stabilization exercise of individual muscles were being performed, activation of the muscles was measured using surface electromyography (EMG). Activation of the muscles while performing stabilization exercise in four-point kneeling on the unstable surface was normalized to a percentages of the MVIC. Results : TrA/IO, MF muscles showed no significant differences among the surfaces. Conclusion : Activation of the trunk muscles while performing stabilization exercise in four-point kneeling does not effect on the surface.
