Objective: The purpose of this study was to investigate the effects of sling exercise on the cervical lordotic angle, craniovertebral angle, and head rotation angle among adolescents in the forward head posture. Methods: The subjects include 22 adolescents that recorded a mild level or higher on the posture evaluation index by New York State. They were randomly divided to the hand exercise group (n=11) and the control group (n=11). The former group participated in the sling exercise program three times a week over four weeks in total with each session lasting 60 minutes, whereas the latter group was not included in the program. The cervical lordotic angle, craniovertebral angle, and head rotation angle were measured before and after the intervention. Results: The study compared the cervical lordotic angle between the two groups before and after sling exercise and found that the sling exercise group made an increase of $7.36^{\circ}$ from $21.91^{\circ}$ to $29.27^{\circ}$ after the intervention(p<.05). As for the comparison results of the craniovertebral angle, the sling exercise group made an increase of $5.64^{\circ}$ from $48.91^{\circ}$ to $54.55^{\circ}$ after the intervention (p<.05). As for the comparison results of the cranial-rotation angle, the sling exercise group made an decrease of $-7.73^{\circ}$ from $148.82^{\circ}$ to $141.09^{\circ}$ after the intervention (p<.05). The control group showed no differences before and after the intervention (p>.05). Conclusion: Those findings indicate that the application of sling exercise in the forward head posture can be a good program to maintain the right posture and improve or prevent an abnormal posture and raise a need for more clinical applications and ongoing researches.

Purpose : This study was done to examine the actual effect of the scapular position in these flexibility tests. The purpose of this study was to examine the differences between the measurement of SRT(Sit-and-Reach Test) without intentional abduction of the scapular (pre-test) and with intentional abduction of the scapular (post-test). The hypothesis is: 1. There is no differences in the SRT result of the pre-test and the post-test. 2. There is no differences in the HJA(Hip Joint Angle) result of the pre-test and the post-test. 3. There is no differences in the Spine Motion Test(SMT) result of the pre-test and the post-test. Method : The total 60 people (30 men, 30 women) were participated in this study. In the pre-test, the subjects were asked to sit on the examination table and try the SRT motion; and then the HJA, SRT and the SMT numerical values were taken. In the post-test. the subjects were instructed to intentionally bring the scapula outward from the midline; and the HJA, SRT and the SMT numerical values were taken. Result : In the pre-test. the SRT result averaged 34.17cm. and in the post-test. the SRT result averaged 36.68cm. The difference was about 2.81cm which showed a significant mean statistically (p<0.01). The measurement increased by 8.22%. The HJA was $85.9^{\circ}$ in pre-test, and it was $85.5^{\circ}$ in post-test. giving the $0.4^{\circ}$ differences. Therefore, it didn't have a statistical mean (p>0.05). The SMT value was 69.56cm in the pre-test. and it was 69.28cm in the post-test, about 0.28cm decreased. Therefore, it didn't have a statistical mean (p>0.05). SRT values and HJA values were correlated (p<0.01). SMT values and SRT values (p<0.01), and SMT values and HJA values(p<0.05) were each in counter correlation. Conclusion : The result of the SRT without intentional scapular abduction (34.17cm) and with intentional scapular abduction (36.68cm) showed a significant increase about 8.22% (p<0.01). In SRT, the effect of the intentional scapular abduction on SMT showed no significant means, the pretest value being 69.56cm and the post-test value being 69.28cm (p>0.05).

Purpose : The purpose of this study was to investigate the effect of tensor fasciae latae length on the rotation of pelvis during one leg stance. Methods : 41 healthy adults participated in this study. The movement of the pelvis and trunk was measured using 3-dimensional motion analyzer, during one leg stance. The movement of the pelvis and trunk was collected lateral shift, rotation, side bending, and flexion-extension. Tensor fasciae latae length of subjects was measured in sidelying positon with neutral position of hip joint and flexion $90^{\circ}$ of knee. Also, the range of motion of hip exteral and interal rotaion were measured in prone position wih lexion $90^{\circ}$ of knee. The subjects were separated 2 groups that more pelvic rotation group(n=15) and less pelvic rotation group(n=15) according to the degree of pelvic rotation. Results : The more pelvic rotation group was showed significantly higher in the ROM of hip external rotation than less pelvic rotation group(p<0.05). The difference of tensor fasciae latae length not showed significant difference between groups. During one leg stance, The movement of the shifting and flexion-extension of trunk and pelvis were not showed significant difference. But the side bending and the rotation of pelvis and trunk showed significant difference between groups. Conclusion : The difference of tensor fasciae latae length not showed significantly in more pelvic rotation group and less pelvic rotation group. But, this study suggests that the pelvis instability brings the instability of the trunk during one leg stance.

Background: The purpose of this study was to realize the relations between gluteus medius, tensor fascia lata of pelvic muscles and functional leg length in women's university students. This study is examined the change of electromyographic activation on gluteus medius and tensor fascia lata according to the leg length discrepancy. Methods: All of the female of freshman and sophomore in 'D'college were gathered and separated fourteen of healthy women in two groups by functional leg length discrepancy. and The subjects divided into two groups that the difference with less than 2cm or more would have structural defects by tapeline. The electromyographic activation on the gluteus medius and tensor fascia lata muscles were recorded by surface electrodes at maximal voluntary isometric contraction (MVIC) during lunge posture. The collected datas were analyzed using Independent t-test with SPSS win19.0. Results: In intergroup comparison of electromyographic activation levels for gluteus medius and tensor fascia lata in short or long leg, the influence of electromyographic activation on tensor fascia lata is shown to be more statically higher than gluteus medius according to functional leg length discrepancy in coeds. Even though both muscles are shown to be statistically higher in comparison of electoromyographic activation levels for tensor fascia lata and gluteus medius between short leg and long leg in Group I, Differences of electoromyographic activation levels for tensor fascia lata is shown to be statistically higher than gluteus medius. Conclusion: Through this study, we realized that tensor fascia lata than the long leg, and also, tensor fascia lata is significantly effective for functional leg length discrepancy than gluteus medius. It leads to pelvic lateral instability. This means that cause tensor fascia lata to have a leg length discrepancy.

Background: Bulgarian split squat (BSS) is beneficial to improve dynamic balance ability and muscle activity of lower extremities, however its effects have not been fully investigated. Therefore, this study aimed to compare changes in dynamic balance ability and muscle properties according to various modifications of BSS exercises. Methods: Thirty healthy male volunteers participated in this study, and they were randomly divided into three different groups. The subjects performed the BSS exercise either on a stable surface with the eyes opened (n=10) or eyes closed (n=10), and on an unstable support plane with eyes opened (n=10) conditions, respectively. Dynamic balance ability was measured via Biodex balance system under the eyes-opened and closed conditions. Additionally, muscle properties of the rectus femoris (RF), vastus medialis (VM) and vastus lateralis (VL) were evaluated. Results: Dynamic balance ability did not show the significant differences among the groups that performed the BSS exercises. However, in the Unstable group, there were significant differences in the overall stability index and anterior posterior stability index under the eyes-closed condition between pre-exercise and post-exercise. In comparison of muscle properties according to the groups, RF muscle showed a significant difference in amount of change of elasticity (p=.038). Additionally, there were significant changes in post measurements of VM muscle tone (p=.016), stiffness (p=.012) and elasticity (p=.002). VL muscle, however had no significant differences in muscle properties. Conclusion: These results indicate that BSS exercises could induce the alteration of RF and VM muscle properties, in particular VM muscle which is susceptible to weakness. Thus, BSS could be applied in various ways as an effective rehabilitation exercise.

Background: This study investigated the effects of face-to-face and non-face-to-face McKenzie exercises and elastic band strengthening exercises on falls and fitness in older adults. Methods: A total of 44 subjects were divided into a face-to-face group (FG; n=22) and a non-face-to-face group (NFG; n=22) who met older adults. Both groups used McKenzie exercises and strength training with elastic bands The fall efficacy scale (K-FES) and glycosylated hemoglobin (HbA1c) Pro were used to compare the senior fitness test (SFT). Results: No significant differences were detected between the two groups before the intervention; however, a significant difference was noted in the K-FES scores after the intervention. The change in HbA1c after the intervention was not statistically significant in the FG or the NFG, and no significant difference was detected between the two groups. The change in lower limb muscle strength in the elderly physical fitness test showed no significant difference between the two groups before or after the intervention. The change in upper limb flexibility after the intervention was not significantly different in the FG or NFG, indicating no significant difference between the two groups. The change in the 3-meter round-trip test after the intervention was significantly different in both the FG and NFG groups, but the difference between the groups was not statistically significant. The change in the grip strength test of the dominant hand showed no significant difference after the intervention in the FG or the NFG, and the difference between the FG and NFG groups was not statistically significant. The dominant foot external standing after the intervention was significantly improved in the FG, but no significant difference was detected in the NFG, and the difference between the two groups was not statistically significant. Conclusion: The study findings revealed that FG and NFG McKenzie exercises and elastic band strengthen exercises were equally effective at preventing falls and improving fitness in older adults.

Background: Lumbar joint dysfunction is reported to be the main cause of lower back pain (LBP). The purpose of this study was to evaluate the effect of joint dysfunction on the postural balance of the lower hack and pelvis in different normal activities such as walking or stair management. Also it was studied whether the status of LBP (intensity and duration of LBP, length of treatment) contributes to die pelvic height difference (PHD) in various postures. Subjects: 28 patients with LBP and 32 normal adult volunteers, 60 years of age or younger, who came to the Community Health Center and orthopedic clinics in Incheon, South Korea. Methods: In order to determine the accuracy of the manual angulometer method in measuring the PHD, it was compared to the pelvic x-ray method in selected subjects. In the manual angulometer method, the arm of the angulometer was placed on the top of both iliac crests. The PHD was measured in static upright stance, then one-legged stance, on the affected leg or unaffected leg each time. Information regarding the disease status was obtained through interviews. Visual assessment scale was used to grade the intensity of LBP. Data analysis was performed using SPSS 10.0/PC program. Homogeneity between the two groups was tested by 2-test and t-test. To compare the PHD of the subgroups, we used t-test, F-test and two-way ANOVA. Relationships among dependent variables were analyzed by Pearson correlation analysis. Conclusion: In patients with LBP, lumbar joint dysfunction causes lumbar and pelvic postural asymmetry during normal activities.

This research have been made to define how the IADL (Instrumental Activity of Daily Living) performance and the subjective health index of the Aged are affected by their residential circumstance, gender and age, and how deeply these two factors are related and interact. For the period of June 1 to July 31, 2000, we had conducted a questionnaire and direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent area, grouping into three different residential types The Aged living at home, The Aged living at welfare facilities and The Aged living alone, and studied on how the IADL performance and the subjective health index of the Aged are influenced and interact as per their characteristics, daily activity and mentality. We had analyzed all the data obtained through this research by the method of : - analysis of frequency as per specific factors by SPSS 1O.0/PC+, - $x^2$ test, - t-test, - ANOVA, - multiple regression analysis by factors. The research concludes followings : a. It appears that the three (3) factors such as gender, age and residential circumstance of the Aged deeply affect the IADL performance and subjective health index of the Aged. (p<0.01) b. With regard to IADL performance of the Aged by the gender, it was analyzed that the female-Aged gains 23.8 point on average, which shows the performance of the female-Aged is less independent. (p<0.01). In addition, it was also found that the IADL performance is becoming less and less independent following their age increasing. In analyzing IADL performance by the residential type, it appears that the Aged living at welfare facilities gains the lowest 21.5 points and is least independent. It was also found that the Aged living at welfare facilities need some assistances from others for their performing IADL. (20-24 point) (p<0.001) c. With regard to the subjective health index of the all-Aged participated in this research, the analysis indicates 8.8 point and this is considered as a point of general standard (7-10 point). In analyzing this index by the gender, the female-Aged gains only 8.6 point which explains a lot of female-Aged consider they are not really healthy. (p<0.001) In analyzing this index by the residential type, the Aged living at welfare facilities and the Aged living alone gain the comparatively lower point, - respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged living at these two residential types express they are obviously in a bad situation of health. (p<0.001) d. With regard to the factors affecting the IADL performance and the subjective health index of the Aged, it was analyzed that the IADL performance can largely be affected by the factors such as depression, frequency of going-out and age rising, and that the subject health index can also deeply be affected by depression, pain and by how much they are satisfied with their current living conditions. e. It was analyzed that the interacting between the IADL performance and the subjective health index is not that strong but even weak. As a result, we were able to conclude that the IADL performance is less independent in case of the female-Aged, the Aged living at welfare facilities, and following the age rising. As for the subjective health state the Aged themselves are aware of, we concluded that the female-Aged, the Aged living at welfare facilities and the Aged living alone, are more critical about their health. From this research, we were able to realize that, when the OMT (Orthopedic Manual Therapy) needed, the physical therapists are really required to have a correct and cautious understanding of the situation in which the aged persons are, and take care of them with more concerns and more improved treatment.
