The aim of this study was to investigate the effect of abdominal drawing-in maneuver (ADIM) on peak exploratory flow (PEF), forced exploratory volume in 1 second ($FEV_1$), and low back pain during forced expiration. Twenty-two subjects (14 subjects in experimental group, 8 subjects in control group) participated in this study. The stabilizer was used for ADIM training for five consecutive days. Vitalograph PEF/$FEV_1$ DIARY and visual analogue scale (VAS) were used to determine forced expiratory pulmonary function and low back pain, respectively. Independent t-test and analysis of covariance were used for statistical analysis with a significance level of .05. The findings of this study were as follows: 1) There were no significant differences of ADIM effect on PEF and $FEV_1$ between experimental group and control group. 2) There was a significant pain reduction in experimental group with ADIM. 3) PEF and $FEV_1$ increased significantly in the fifth day compared with the first day pre-exercise baseline. Therefore, it is concluded that ADIM was effective in improving PEF and $FEV_1$, and reducing VAS during forced expiration in patients with chronic low back pain.

Purpose: This study examined the muscle activities of the erector spinae (ES) and gluteus maximus (GM) during bridging exercises with and without abdominal-hollowing. Methods: Nineteen healthy subjects with no medical history of low back pain or hip flexion contracture were enrolled in this study. The subjects performed bridging exercises with and without abdominal hollowing or with and without a one-leg lift. The muscle activities of the ES and GM were measured by surface electromyography during bridging exercises under each condition. A 2 (abdominal hollowing)X2 (one-leg lift) repeated ANOVA was used to compare the normalized muscle activities of the ES and GM. Results: The muscle activity of the ES during bridging exercise with abdominal-hollowing was significantly smaller than that without abdominal-hollowing (p=0.00). The muscle activities of the GM during bridging exercise with abdominal-hollowing were significantly greater than those without abdominal-hollowing (p=0.00). In addition, the muscle activities of the GM during bridging exercise with one-leg lifting was significantly greater than that without one-leg lifting (p=0.00). Conclusion: Bridging exercise with abdominal-hollowing appears to be more effective on activating the GM muscle than that without abdominal-hollowing minimizing the activation of the ES muscle.

Purpose: The purpose of this study was to identify the effectiveness of back pain prevention intervention program on reducing back pain of patients undergoing percutaneous coronary intervention (PCI). Methods: The patients were divided into two groups as the experimental group and control group. In the experimental group, the participants took bedrest for 4 hours after PCI and then received back pain prevention intervention program (BPPIP). Total of 5 times BPPIP with 1 hour interval for 5-10 minutes per each intervention was administered to the patients taking bedrest for 4 hours after PCI. In the control group, total of 5 times routine nursing care with 1 hour interval was administered to the patients taking bedrest for 4 hours after PCI. The data were collected on admission in the ICU and after the 5 exercise sessions. The collected data were analyzed using SPSS/WIN program. Results: No significant differences in the occurrence of hemorrhage after the BPPIP were observed between the experimental group and the control group. After the BPPIP, back pain outcomes were significantly low in the experimental group. However, urination disorder and cortisol level did not show a statistically significant differences between two groups. Conclusion: It is clear that BPPIP is a useful nursing intervention for reducing back pain of patients undergoing PCI.

Purpose: The aim of this study was to determine the effectiveness of breathing exercises and lumbar segmental exercises on the segmental stability of patients with chronic back pain. Methods: Fifty-nine patients, who suffered from chronic low back pain, were enrolled in this examination. They were divided randomly into three groups: experiment group 1 underwent breathing and segmental stabilization exercises (n=20), experiment group 2 experienced segmental stabilization exercises (n=20), and the control group was given the modality treatment (n=19). The measurements were assessed through an Oswestry disability questionnaire (ODQ), as well as a lumbar segmental instability test (LSIT). Results: The ODQ results for experimental groups 1 and 2 were similar (p<0.05), both before and after six weeks of exercise, but different among the three groups (p>0.05). The differences in segmental instability of each of the three groups were similar (p<0.05), and also similar among the three groups (p<0.05). Conclusion: These findings suggest that lumbar segmental stabilization exercises are efficient in increasing the segmental stability and alleviating pain in patients with chronic back pain. Additional studies on this subject will be needed to improve the clinical applications in the future.

Purpose: This study was conducted in order to determine the effect of visual and tactile feedback on muscle activity of the gluteus maximus (Gmax) and abdominal muscles and the motion of pelvic rotation during performance of clam exercise (CE). Methods: Thirteen subjects without low back pain were recruited for this study. Each subject was instructed to perform the CE without and with feedback. The subjects were instructed to keep pelvic from rotating backwards by palpating the ASIS and monitoring the pelvic movement by themselves during performance of CE with feedback. The electromyographic (EMG) activities of Gmax and abdominal muscles were collected using surface EMG. Angles of pelvic rotation were measured using a 3-dimensional motion-analysis system. Paired t-tests were used for comparison of EMG activities in each muscle and the angle of pelvic rotation. Results: The EMG activities of all abdominal muscles were not significant between CM without and CM with feedback (p>0.05). The EMG activity of Gmax was significantly greater in CM with feedback compared with CM without feedback (without vs. with feedback; 14.2% vs. 20.7%MVIC) (p<0.05). The angle of pelvic rotation was significantly less in CM with feedback compared with CM without feedback (without vs. with feedback; $15.3^{\circ}$ vs. $10.8^{\circ}$ ) (p<0.05). Conclusion: Therefore, these findings suggest that CM with the visual and tactile feedback is effective in activation of the Gmax and correcting of the uncontrolled lumbopelvic rotation during CE.

To investigate the effects of self-management programs for chronic low back pain (LBP), 63 subjects were assigned to three groups; self-exercise group (SEG), hot pack and low-frequency electrical stimulation group (HEG), and thermo-massage group (TMG). Parameters were the pain numeric rating scale (PNRS), Oswestry Disability Index (ODI), Roland Morris Disability Questionnaire (RMDQ) and Relapse frequency (RF). PNRS, ODI and RMDQ of SEG and TMG sustained effectiveness, however, PNRS, which improved after treatment in HEG, worsened in 6 month. Between the groups, all parameters were better in SEG and TMG compare to HEG. Exercise and thermo-massage can be considered as useful self-management performed at home to prevent the relapse of chronic LBP.

Although many current low back pain exercise incorporate proprioceptive training, very little research has been performed on proprioception of the low back. To determine wether reposition error is different in male than female. Eighteen young individuals took part in the research, seven male and eleven female. The 3-dimensional position of the lumbar was measured with a CMS70P. Reposition error was calculated as the absolute difference between the neutral position and return position. No significant differences in reposition error were found between male and female. No significant correlations were identified between reposition error and movement direction.

The purpose of this experimental study is to investigate the relationship between English pronunciation and listening comprehension of English diphthongs and low vowels of Korean college students from the Chungnam and Gyungnam provinces. Of 22 test sentences for listening comprehension, 15 sentences were recorded by native speakers and seven sentences were edited from Springboard by Oxford University Press. For the listening comprehension test, 90 subjects from two groups, Chungnam dialect speakers and Gyungnam dialect speakers, were selected. They listened to 22 sentences produced by audio cassette tape and completed a cloze exercise. By the results of this experiment, we observed that Korean collegians of Gyungnam province showed a better listening comprehension of words including front low vowels when they preceded voiced sounds than those of Chungnam province. When the back low vowel came in an open syllable, we also recognized the same result; Gyungnam province collegians showed better listening comprehension of words including back low vowels than those of Chungnam province. As the results of Hee-Suk Park & Jung-Soak Kim(2003) showed that Gyungnam province collegians pronounced the English low vowels longer than Chungnam province collegians, we discovered that there was a positive relation between English pronunciation and listening comprehension, especially in Gyungnam province collegians. However regarding words including English diphthongs we discovered almost no relation between English pronunciation and listening comprehension.
