PURPOSE: Hamstring muscle shortening is related to low back pain, and it is important to check the hamstring muscle flexibility and pelvic mobility to analyze the effects of the intervention. This study examined the effects of hamstring muscle shortening on flexibility and pelvic mobility according to the method of stretching the hamstring muscle in patients with low back pain. METHODS: Forty Low Back Pain Patients participated. The subjects performed the Visual Analogue Scale (VAS), Fear Avoidance Belief Questionnaire (FABQ), Korean version of Oswestry Disability Index (KODI), Myovision, and sensbalance therapy cushion (pelvic mobility, proprioception). The subjects were divided into two groups to perform the passive and active stretching protocol. The intervention was conducted three times a week for four weeks. RESULTS: Hamstring muscle flexibility was increased significantly in both groups (p < .05), and there was no difference between the groups. VAS, FABQ was decreased significantly in both groups (p < .01), and there was no difference between the groups. The left lower back muscle impedance was decreased significantly in both groups (p < .05). The passive stretching group showed a significant increase in the pelvic anterior, posterior, and left tilt ROM (p < .05). The active stretching group showed a significant increase in the pelvic anterior, posterior tilt ROM (p < .05). CONCLUSION: Both stretching methods may be useful intervention methods for pelvic mobility and pain recovery and can assess back pain recovery.

Objective : The purpose of this study is to report the results of treating patients with acute low back pain syndrome who are difficult to walk with Whidam's Vibrator Pelvic Sugi Therapy. Methods : We used combinations of korean medicine such as herbal medicine, acupuncture, cupping therapy, and thermal therapy. At the same time, the patient was treated with Whidam's Vibrator Pelvic Sugi Therapy. The first period of hospitalization was 14 days and the second period was 54 days. At the second hospitalization, back pain recurred and was unable to walk. At the first hospitalization, L5-S1 HIVD and L4-5 Mild HIVD were diagnosed on lumbar MRI, and there was no abnormality in blood tests. Results : By relieving muscle tension and restoring the weakened muscle elasticity with herbal treatment and Whidam's Vibrator Pelvic Sugi Therapy, back pain decreased and the inability to walk gradually improved, making it possible to walk on its own. Conclusions : The results of standing and walking on one's own were obtained by relieving muscle tension and restoring weakened muscle elasticity in acute back pain syndrome with gait disturbance diagnosed with lumbar herniated intervertebral disc through korean medicine treatment and Whidam's Vibrator Pelvic Sugi Therapy. Whidam's Vibrator Pelvic Sugi Therapy is thought to help acute back pain by restoring muscle elasticity and strengthening muscle strength. In the future, it is expected that additional clinical studies will be conducted on various pain diseases with Whidam's Vibrator Pelvic Sugi Therapy.

Purpose: To investigate the various imaging factors associated with aggravation of lumbar disc herniation (LDH) and develop a scoring system for prediction of LDH aggravation. Materials and Methods: From 2015 to 2017, we retrospectively reviewed the magnetic resonance imaging (MRI) findings of 60 patients (30 patients with aggravated LDH and 30 patients without any altered LDH). Imaging factors for MRI evaluation included the level of LDH, disc degeneration, back muscle atrophy, facet joint degeneration, ligamentum flavum thickness and interspinous ligament degeneration. Flexion-extension difference was measured with simple radiography. The scoring system was analyzed using receiver operating characteristic (ROC) analysis. Results: The aggravated group manifested a higher grade of disc degeneration, back muscle atrophy and facet degeneration than the control group. The ligamentum flavum thickness in the aggravated group was thicker than in the group with unaltered LDH. The summation score was defined as the sum of the grade of disc degeneration, back muscle atrophy and facet joint degeneration. The area under the ROC curve showing the threshold value of the summation score for prediction of aggravation of LDH was 0.832 and the threshold value corresponded to 6.5. Conclusion: Disc degeneration, facet degeneration, back muscle atrophy and ligamentum flavum thickness are important factors in predicting aggravation of LDH and may facilitate the determination of treatment strategy in patients with LDH. The summation score is available as supplemental data.

In order to observe the effect of mandibular orthopedic repositioning appliance (MORA) on body strength, the author measured back muscle strength with Digital Back Muscle DYNAMOMETER (TAKEI KIKI KOGYO Co., Tokyo, Japan) before MORA, 15 days after and 30 days after MORA in 12 men and then analysed them statistically. The subjects were weight-lifting athletes of Seoul Athletic High School without dysfunction of masticatory system. MORA was fabricated at 1.0-1.5rnm isotonically closed position (Myocentric Occlusion Position) from mandibular rest position (Myocentric Rest Position) using Myo-monitor (MyoTronics Research Inc., Seattle, Washington, USA) and-SVT C-II (Tokyo Shizaisha Inc., Tokyo, Japan). The results were as follows : 1. The mean of back muscle strength before MORA was 150 kg, that of 15 days after MORA was 165 kg (4.43% increase than before), and that of 30 days was 175 kg (10.76% increase than before). 2. There was a significant difference among back muscle strength before MORA, 15 days after and 30 days after MORA (P<0.01: repeated measures one-way ANOVA). 3. According to the result of determining mandibular position for MORA fabrication, mandibular rest position after relaxation with Myo-monitor was 3.2mm lower, 1.0mm posterior, and 0.5 mm left from centric occlusion. And the mean of the amount of lateral deviation was 0.7 mm.

Objective: The purpose of this study is to investigate the effect of stabilization exercise on whole-body vibration on pain, dysfunction, psychosocial factors, balance ability, and abdominal contraction with patients with low back pain. Design: A randomized controlled trial Methods: A total of 34 patients with low back pain were assigned randomly to experimental group (n=17) and control group (n=17). Both groups underwent a neuromuscular stabilization exercise program. In addition, the experimental group implemented the neuromuscular stabilization exercise program using whole-body vibration. All interventions were applied 60 min per session, 3 times per week for total 4 weeks. Numeric Rating Scale (NRS), Korean version of Oswestry Disability Index (K-ODI), Fear-Avoidance Beliefs Questionnaire (FABQ), balance ability, muscle thickness and contraction ratio were compared to evaluate the effect on intervention. Results: Both groups showed significant differences in NRS, balance ability, and muscle thickness in contraction, contraction ratio before and after intervention (p<0.05). In addition, the experimental group showed significant difference in the amount of change in NRS, balance ability and muscle thickness in contraction, contraction ratio values than the control group (p<0.05). Conclusions: Neuromuscular stabilization exercise program combined with whole-body vibration stimulation has been proven to be an effective and clinically useful method to decrease pain, dysfunction, increase balance ablilty, and transverse abdominis muscle thickness in contraction and contraction ratio for patients with low back pain.

PURPOSE: This study examined the effects of the resistance levels on the muscle activities around the hip and spine during bridge exercise with hip abduction resistance in patients with chronic back pain. METHODS: A cross-over study design was used. Twenty subjects with low back pain were enrolled in this study. The subjects performed bridge exercises with hip abduction resistances (20 mmHg, 40 mmHg, and 60 mmHg). A Narrow Sling was used to provide resistance. Surface electromyography was used to measure the activity of the erector spinae, biceps femoris, gluteus maximus, and gluteus medius. RESULTS: The muscle activity of the gluteus maximus and gluteus medius increased significantly with increasing resistance levels. There was a significant difference in the muscle activity of the biceps femoris with a resistance level between 20 mmHg and 40 mmHg, but there was no significant difference in the other resistance levels. There was no significant difference according to resistance level in the erector spinae. The muscle activity ratios of the gluteus medius/erector spinae and gluteus maximus/erector spinae increased significantly with increasing resistance strength. CONCLUSION: The different levels of abduction resistance for hip abduction during bridge exercise will help activate the gluteus maximus selectively in patients with chronic back pain.

The purpose of this study was to compare the onset times of muscle activities and the order of muscle firing in hamstring gluteus maximus, and lumbar erector spinae muscle during active hip extension between subjects with low back pain (LBP) and healthy subjects. Thirty subjects, 15 with LBP and 15 healthy subjects, participated in this study. Electromyographic activity was recorded during active hip extension in prone and standing position. Relative onset times of these muscle activities were determined. Similar muscle firing order in hamstring, gluteus maximus, and lumbar erector spinae muscle showed in both groups and positions. However, the onset time of gluteus maximus was significantly later in prone and standing active hip extension in subjects with LBP than in healthy subjects. The onset time of lumber erector spinae muscle activity was significantly delayed in subjects with LBP in standing active hip extension, The delayed onset times of gluteus maximus and lumbar erector spinae muscles' activities were probably related to LBP. Further studies are needed to identify whether the delayed onset times of gluteus maximus and lumbar erector spinae muscle activities are the contributing factors to LBP.
