Background: A limited hip rotational range of motion (ROM) has been considered to be one of characteristics of low back pain (LBP) in athletes. Although LBP frequently occurs in jiu-jitsu athletes, no previous has compared hip rotational ROM between jiu-jitsu athletes with and without LBP. Objects: The aim of the study was to compare ROM for hip internal rotation (IR) and external rotation (ER), and total hip rotation between jiu-jitsu athletes with and without LBP. Methods: Jiu-jitsu athletes were recruited for the LBP group ($n_1=15$) and control group without LBP ($n_2=15$). IR, ER, and total rotational range of hip joint were measured using a goniometer. Analysis of variance was used to compare the ROM between groups and sides. Results: The LBP group showed a significantly lower range of passive hip IR, passive total rotation, active IR, active ER, and active total rotation than the control group (p<.05). Dominant side of passive hip IR and active IR had a significantly lower ROM than non-dominant side (p<.05). In passive ER ROM, non-dominant side was significantly greater than dominant side (p<.05). Conclusion: Compared to jiu-jitsu athletes without LBP, athletes with LBP exhibit a loss of hip rotational ROM. Based on these results, clinicians and athletic trainers should measure hip rotational ROM when designing the management plan for jiu-jitsu athletes with LBP.

Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

Purpose : The purpose of this study is to investigate the instant effect of Kinesio taping on pain decrease and improvement of functional disorder of the subjects who have lumbar instability. Methods : A total of 20 patients (13 men and 7 women) who have lumbar instability were chosen as the subjects. The experiment was conducted by assigning the subjects into Kinesio taping group and placebo taping group. A visual analog scale (VAS) was used to measure back pain and Biering-Sorensen test was applied to measure the muscle endurance of back extensor muscles. A digital dynamometer was used to test the isomeric contraction strength of lumbar extensor muscle. The subject performed single-leg stance and double-leg stance task and their static balancing ability was measured by a testing device that captures the static balancing ability. Results : In a within-group comparison, Kinesio taping group showed a significant decrease of VAS (p<.05) and a significant increase of endurance and strength of lumbar extensor muscle (p<.05). In Kinesio taping group, the shift distance in anterior-posterior sway and medial-lateral sway during the double-leg stance significantly decrease (p<.05). The shift distance in anterior-posterior sway and medial-lateral sway also significantly decreased during the single-leg stance (p<.05). Placebo taping group showed a significant decrease of visual analog scale (p<.05). In a between-group comparison, Kinesio taping group showed a significantly larger decrease of VAS (p<.05), significant larger increase of muscle endurance and muscle strength (p<.05), and significant larger decrease of anterior-posterior sway in the double-leg stance (p<.05), compared to placebo taping group. Conclusion : Application of Kinesio taping to the subjects with lumbar instability produced positive effect of reducing pain, increasing muscle strength and endurance, and improving static balancing ability.

Purpose : The aim of this study was to investigate the change of the respiratory function of chronic low back pain patients after the thoracic manipulation and the trunk stability exercise on chronic low back pain patients. Methods : For this study, the group of the experiment was consisted of 44 patients suffering from the low back pain chronically. The participants were divided into two groups: the control group, which was assigned for core stabilization exercise (CSE), and the experimental group, which was randomly assigned for core stabilization exercise after thoracic manipulation (CSE+TM). Both groups carried out each assigned treatment on three times a week for 8 weeks. To study the change related to measurement variable from each test groups before and after intervention, paired t-test was performed. Further, the statistics for an intergroup comparison was analyzed by covariance analysis, ANCOVA. The measurement was conducted by the respiratory function, the respiratory function was measured by forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁). Results : As a result, forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) showed significant differences not only by each groups but also between those groups before and after the test. Conclusion : In conclusion, both experiments, the core stabilization exercise and the core stabilization exercise conducted after thoracic manipulation, on chronic low back pain patients resulted in the significant level of difference in the respiratory function. This result indicates that the thoracic manipulation is an efficient treatment for improving the respiratory function for chronic low back pain patients.

The purpose of this study was to investigated the muscle activity difference of lower extremity by abdominal co-contractive activation. 30 healthy women without pain in the low back and lower extremity were conducted. Muscle activities of lower extremity were measured with the active straight leg raise (ASLR) in 20cm raised from the floor without bending the knee at rest, abdominal drawing-in maneuver (ADIM) and abdominal bracing maneuver (ABM), respectively. Hip adductor longus (HadL), rectus femoris (RF), and biceps femoris (BF) muscle activity in the Abdominal bracing maneuver were statistically significantly higher, also gluteus medius (Gmed) and tibialis anterior (TA) muscle activity in the ADIM were higher. We provide the evidence to the positive effects of individual abdominal co-contractive activation training which can enhance postural stability and lower extremity strengthening with volitional preemptive abdominal contraction.

PURPOSE: Chronic low back pain is one of the main factors that affect the quality of life and cause problems of gait and balance in elderly people. This study investigated the correlation between the Oswestry disability index (ODI), Berg balance scale (BBS), and kinematic data measured while analyzing the gait of elderly people with chronic back pain. METHODS: A total of 29 subjects participated in this study. The ODI, BBS, and kinematic data of lower extremities were measured while walking. All data were analyzed using Pearson's correlation coefficients and the significance was measured at .05. RESULTS: ODI had a significant correlation with 1, 13, and 14 items of BBS (p < .05), and left hip external rotation and right ankle abduction respectively in the stance and swing phase of gait (p < .01). 13 items of BBS had a significant correlation with the right ankle abduction in the stance phase of gait (p < .01). In addition, 14 items of BBS had a significant correlation with right and left ankle abduction in the stance and swing phase of gait (p < .01). CONCLUSION: While attempting to predict chronic low back pain and balance issues, it may be useful to check the right ankle abduction in the stance and swing phase of gait. In the future, it would be helpful if some simple tests could be designed to assess balance in elderly people with chronic low back pain.

PURPOSE: This study examined the effects of an active tailored exercise program on pain and the Oswestry disability index (ODI) among workers with musculoskeletal symptoms of the lower back in an automobile parts manufacturing company. METHODS: Twenty-two workers with musculoskeletal symptoms of the lower back were included in the study. The experimental group was composed of 15 workers and a control group of seven workers. The experimental group was provided an active tailored exercise program and education on the risk factors of musculoskeletal disorders. The control group was only provided ergonomic education. The exercise program, which consisted of movement pattern correction, muscle stretching and strengthening, and postural correction exercises, was applied twice a week for two months for one hour a day. Pain, which was determined using a visual analogue scale (VAS), and the ODI were measured before and after exercise. RESULTS: After applying the exercise program for two months, the VAS and ODI of the experimental group were significantly lower than those of the control group (p<.05). In the experimental group, the VAS decreased significantly after one month (p<0.05), and the ODI decreased significantly after two months (p<.05). CONCLUSION: Because active tailored exercise programs are effective in improving the pain and disability indices, it is necessary to actively implement such programs among manufacturing workers with musculoskeletal symptoms of the lower back.

Purpose: This study compares and examines the effects of proprioceptive neuromuscular facilitation (PNF) on patients with chronic low back pain through systematic literature review and meta-analysis. Methods: Domestic literature was searched with combinations of keywords including "proprioceptive neuromuscular facilitation," "PNF," "back pain," and "low back pain" using the Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS), and Korean Medical Database (KMbase). Six studies (n=148) were finally included in the analysis through a selection and exclusion process. The quality of the studies was evaluated using the PEDro scale. Results: According to the meta-analysis results, the low back pains of the PNF group and the contrast group showed a standardized mean difference (SMD) of 2.21 (95% CI: -3.35, -1.07, p=0.01, $I^2=83%$) after intervention. Thus, the PNF group showed a statistically significant decrease in low back pain compared with the control group. In addition, the SMDs of the Oswestry Disability Index (ODI), lung function, and the Roland and Morris Disability Questionnaire (RMDQ) were -1.34 (95% CI: -1.88, -0.79, p<0.01, $I^2=35%$), 1.14 (95% CI: 0.49, 1.79, p=0.01, $I^2=0%$), and -1.59 (95% CI: -2.56, -0.62, p=0.01, $I^2=46%$), respectively. Thus, the PNF group showed statistically significant differences from the control group. Conclusion: At present, there is some limit to obtaining definite results about effect sizes because there are relatively few randomized controlled experiments that analyze the effects of PNF exercise in patients with chronic low back pain. Therefore, continuous efforts should be made to conduct randomized clinical trials and long-term efficacy studies in the future.
