Purpose : The purpose of this study was to use oral instruction and taping to induce abdominal draw-in in the previous study, but there is a lack of research on the comparison of effects. Therefore, in this study, we would like to study how the effect of oral instruction, taping, and no feedback can affect muscle activity when performing abdominal draw-in pier exercises. Methods : Before the experiment, group A trained piers and applied only draw-in piers, group B applied taping feedback, and group C were divided into three groups per week for six weeks, and three sets of contractions for five seconds per group were performed five times, and a minute break was provided between each exercise. As a measurement tool, a wireless surface electromyography (EMG) was used to measure surface electromyography (Telemyo-DTS, NORAXON, USA) that derives a synthetic unit of muscle using a surface electrode. For statistical processing of data, the analysis is performed using the SPSS/PC Version 25.0 statistical program for Windows, and the statistical significance level is a=.05 Results : First, the duration was somewhat shorter in order to more accurately compare the muscle activity of the core muscles. Therefore, future research needs to be research that can be exercises with precise biofeedback and taping applied over a longer period of time. Secondly, it is believed that there is no significant difference, since the subjects were studied in healthy young adult men and women, not patients. Thirdly, they could not control the daily life of the subjects. Through future research, it is necessary to analyze the correlation between muscle activity and abdominal muscle thickness by adding ultrasound in addition to muscle activity in various age groups. Conclusion : During draw-in bridge exercise according to feedback, the muscle activity of the back muscle increased, and there was no significant difference in the muscle activity of the back muscle according to each feedback. Therefore, both the feedback applied during the draw-in pier exercise and the control group are effective in changing the thickness of the abdominal muscles.

Objective : To broaden understanding about relationship between Meridian Tendino-musculature and muscles in a lumbar area and to evaluate the effect of Meridian Tendino-musculature acupuncture and release therapy on acute lumbar sprain. Materials and Methods : From Oct. 1st, 2000 to Mar. 31th, 2001, 692 outpatient's chart of Kyung Won University Hospital were reviewed. Out of them, 39 outpatients were selected. they had low back pain, were diagnosed with acute lumbar sprain, showed only straightened curvature on lateral view of lumbar spine X-ray and get the Tendino-musculature acupuncture and release therapy. Results : 1. On patients' first visit, 72% had GrIII and Gr.IV predominantly. 2. Major muscles related with low back pain were divided into two groups. One was Quadratus lumborum group and the other was Rectus abdominis group. In the correlation with Meridian Tendino-musculature, the former was mainly related with Chok-taeyang(B) and slightly related with Chok-soyang(G), Chok-taeum(SP), the latter was mainly related with Chok-taeyum(SP), Chok-yangmyong(S) and slightly related with Chok-taeyang(B), Chok-soyang(G). 3. In the evaluation of treatment effect, Exellent was 27(69%), Good was 10(6%), Fair was 2(5%) and Bad was 0(0%). Fair rate reached 100% eventually. 4. Most of Gr.Ⅲ, Gr.Ⅳ patients who had severe conditions that almost every R.O.M. was limited and Milgram test positive was shown on the physical examination, were fully recovered and lived normal daily life without admission by Meridian Tendino-musculature acupuncture and release therapy within 3 to 5, 4 to 7 days, respectively, since they had started to get their outpatient treatment. 5. Two patients was troubled with pain induced, by twitching response and acupuncure stimuli, which lasted around acupunctured muscle for about a day after treatment, so they coudn't endure the pain and quitted treatment in spite of Fair condition. conclusion : Meridian Tendino-musculature acupuncture and release therapy was found to be helpful to patients who wish to recover from their back pain induced by acute lumbar sprain as soon as possible, but the treatment actually had some problems to be overcome such as pain during or after the treatment. therefor, in order to make this treatment method more available, we should pay more attention to improving treatment appliance and acupuncture technique.
Objective : To compare the effect of Carthmi- Flos herbal acupuncture theraphy and acupucture treatment to Low back pain patient. Methods : 70 patients with Low back pain are evaluated by being divided Carthmi- Flos herbal acupuncture theraphy Group(HAG, 30 peples) and non- Carthmi- Flos herbal acupuncture theraphy Group(NHAG, 40 peoples) at Ik-San Oriental medical hospital in wonkwang university from the first November 2000yr to 31th December 2001yr. Results : 1. In the cause of Low back pain, the most of HAG is acute sprain(9cases, 30%) and NHAG is non-inducement(13 cases, 22.5%). 2. In the analysis of the radiation result, HIVD and Degenerative change respectively were 22 cases(50%) in HAG and 29 cases(52.8 %) in NHAG. 3. The effect of treatment by Duration as follows :Two groups were the most improved highly in acute stage and they were improved lowly in chronic stage(6 month). 4. The effect of treatment by condition of patients was follows: After treatment, Grade IV & III were decreased 69.5% in HAG and 60% in NHAG. 5. In the distribution of treatment progression : 28 cases(93.3%) were recoverd in HAG but 30 cases(90%) in NHAG. Conclusion : These results shows that the effect of treatment by Carthmi- Flos herbal acupuncture treatmen is exellent by relaxing contracted muscles, strengthening weakened ligaments and improving inflammatory parts.
This study aimed to investigate the effect of the abdominal drawing-in maneuver (ADIM) and abdominal expansion maneuver (AEM) on trunk stabilization, as well as trunk muscle activities and differences in quadruple visual analogue scale, Korean Oswestry Disability Index, and Fear Avoidance Beliefs Questionnaire scores, in patients with chronic low back pain and lumbar spine instability. To increase intra-abdominal pressure during the trunk stabilization exercise, the technique of pushing the abdomen out using diaphragmatic abdominal breathing suggested by Pavel Koral was used, which we termed the AEM. Fifty patients who tested positive on more than three of the five lumbar spine instability tests were separated from 138 patients with chronic low back pain of these patients, 16 were placed in the control group (trunk stabilization exercise), 17 were placed in the ADIM group (trunk stabilization exercise with ADIM), and 17 were placed in the AEM group (trunk stabilization exercise with AEM). Each group participated in the study for 30 minutes three times weekly for 4 weeks. Surface electromyography was used to measure the trunk muscle activities during the kneeling forward and supine bridging positions, and one-way repeated analysis of variance was used to determine the statistical significance of the trunk muscle activities in the rectus abdominis, internal oblique (IO), erector spinae, and multifidus (MF) muscles. The ADIM and AEM groups showed relatively larger improvements in psychosocial and functional disability level than control group. There were significant changes among the three groups, those from the measured values of the AEM group was significantly higher than the other two groups in changes in IO and MF trunk muscle activities (p<.05). This finding demonstrates that trunk stabilization exercises with AEM is more effective than ADIM for increasing trunk deep muscle activity of chronic low back pain patients with lumbar spine instability.
The purpose of this study was to investigate the effect of muscle imbalance on motion of back squat. The isokinetic muscle strength of the 8 subjects was recorded for the knee flexion/extension by the cybex 770 dynamometer. Each subject performed 3 back squats with the long barbell with an intensity of 25% body weight(BW), 50%BW, 100%BW, 125%BW. During the back squat through the recorded kinematic data the subjects' maximum flexion and extension knee angle, center of mass displacement and V-COP were calculated for evaluation of the stability of the movement. For the statistical analysis independent t-test was used. Knee flexion angle and COM displacement are dominated by the reciprocal muscle ratio. V-COP factor was dominated by bilateral extension deficit. Based on the results we can know that as the intensity of the squat increased to a level control was difficult because the muscles' imbalance influenced the movement.

This study aimed to investigate the difference of sensory changes by central and peripheral stimulation for improving life care in chronic low back pain patients. Twelve chronic low back pain patients were randomly assigned to central stimulation (CS, n=6) and peripheral stimulation (PS, n=6). Quantitative sensory test (QST), pressure pain threshold (PPT) and Korean oswestry back pain disability index (KODI) were used to quantitatively measure and analyze. As a result, QST, PPT and KODI showed significant differences by period (p<.01) but did not showed any difference between the two groups (p>.05). Therefore, both stimulations had significant effects on increased sensory threshold and function improvement of the muscles that became sensitive due to pain. It is thought to be significant in improving life care for patients with chronic low back pain.
Objectives Objective of this study is to investigate the role of paraspinal muscles by examining the correlation between slip percentage (SP) of spondylolisthesis and fatty infiltration of lumbar paraspinal muscle. Methods Retrospective analysis was performed on 45 patients diagnosed with spondylolisthesis based on medical records. Using T2-weighted axial magnetic resonance imaging, cross-sectional areas (CSAs) of psoas major (PM), multifidus (MU) and erector spinae (ES) were calculated and divided by CSA of lower level vertebral body (VB). SP was measured using sagittal T2-weighted images. Correlation of SP with muscle relative cross-sectional area (RCSA) and muscle fatty infiltration by Goutallier classification was respectively analyzed using Spearman correlation. Statistic assessment conducted by Wilcoxon signed rank test and paired t-test using program GraphPad prism 5 (GraphPad Software, Inc., San Diego, CA, USA). Results Spondylolisthesis forward slip percentage by Taillard's method was negatively associated with both side MU RCSAs. No significant correlation was found between PM RCSA, ES RCSA and SP. Forward slippage was significantly correlated with fatty infiltration of lumbar paraspinal muscle measured by Goutallier classification. Conclusions This study is to understand the role of paraspinal muscle affecting spinal instability by investigating correlation between statistical deviation of lumbar muscle characters (RCSA, fatty infiltration of lumbar muscle) and SP. We found that spondylolisthesis SP is positively related to fatty infiltration of lumbar paraspinal muscle. and is negatively associated with both side MU RCSAs.

The aim of this study ultimately is verifying that PGO gait is more efficient than RGO fur paraplegics because the air muscle assists hip flexion power in heel off movement. The gait characteristics of the paraplegic wearing the PGO or RGO are compared with that of a normal person. PGO with air muscles was used to analyze the walking of patients with lower-limb paralysis, and the results showed that the hip joint flexion and pelvic tilt angle decreased in PGO. In comparison to RGO gait, which is propelled by the movements of the back, PGO uses air muscles, which decreases the movement in the upper limb from a stance phase rate of 79$\pm$4%(RGO) to 68$\pm$8%. The energy consumption rate was 8.65$\pm$3.3 (ml/min/Kg) for RGO, while it decreased to 7.21t2.5(ml/min/Kg) for PGO. The results from this study show that PGO decreases energy consumption while providing support for patients with lower-limb paralysis, and it is helpful in walking for extended times.

In this paper a cervical rehabilitation robot for Mckenzie exercises to be effective to neck pain relief is proposed. The robot has two degrees of freedom (DOF) for Lateral flexion and extension, Dorsal and Vental flexion which enable user to perform cervical stretching and isometric exercises for neck muscles. The mechanical parts of the cervical rehabilitation robot can be mounted on a back- or head-rest of chair, and user can perform the Mckenzie exercise with seated. In experiments we measured the range of motion of cervical part, EMG signals from neck muscles and the contact forces of a head bracket fixing the head part of user, and then evaluated their performances. From the experimental results, we showed a feasibility of the cervical rehabilitation robot proposed in this study.
The purpose of this study was to define the effects of noise and background music on the trunk muscle fatigue during dynamic lifting and lowering tasks. Six healthy male subjects with no prior history of low back disorders participated in this study. The participants were exposed to two levels of background noise such as 40dB noise and 90dB noise and three levels of background music such as no music, slow music, and fast music. Six different combinations of background noise and background music were played while the participants were performing the lifting task at 15% level of Maximum Voluntary Contraction. Electromyography signals from six muscles were collected and fatigue levels were analyzed quantitatively. In results, the 90dB noise increased trunk muscle fatigue and slowed down the recovery. The trunk muscle fatigue was the lowest when the fast music was played for as background. After recovery, the 90dB noise increased trunk muscle fatigue. The trunk muscle fatigue was the lowest when the slow music was played for as background. The results can be useful to manage the cumulative fatigue of trunk muscles due to background noise and music during repetitive lifting and lowering tasks in industry.
