Purpose: This study was conducted to investigate the effect of cigarette smoking on physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) and depression in patients with chronic low back pain. Methods: This study was a cross sectional study and subjects consisted of 60 young males with chronic low back pain. The subjects were allocated to two groups following a self-report survey: cigarette smoking group (n=25) or non-smoking group (n=35). Physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) were measured using objective methods and depression in patients with chronic low back pain was measured using the Korean version of center for epidemiologic studies depression (CES-D) scale. Results: The results of this study were as follows: In physical fitness, the cigarette smoking group showed a significant decrease in abdominal muscle endurance, flexibility, and cardiopulmonary endurance compared with the non-smoking group. Depression index (CES-D scale score) was significantly higher in the cigarette smoking group than in the non-smoking group. Conclusion: These results suggest that cigarette smoking had a negative effect on abdominal muscle endurance, flexibility, and cardiopulmonary endurance in patients with chronic low back pain. In addition, depression of patients with chronic low back pain was affected by cigarette smoking. Thus, we suggested that cigarette smoking may play a significant role in the deterioration of physical fitness and depression of chronic low back pain patients.

Purpose: This study examined the characteristics of gait in patients with chronic low back pain. Methods: The subjects were out-patients suffering from chronic low back pain at the department of physical therapy, B hospital in Seoul. Gait analysis was performed by dividing the subjects into two groups. The study and control group comprised 15 chronic low back pain patients and 14 healthy people, respectively. Gait analysis was performed using a VICON 512 Motion Analysis System to obtain the spatio-temporal and kinematic parameters. Results: First, there was a significant difference in the spatio-temporal parameters between the two groups (p<0.05). Second, the study group showed significant differences in the kinematic parameters during the stance phase (p<0.05). Third, there were significant differences in kinematic parameters in the study group during the swing phase (p<0.05). Conclusion: The gait pattern of patients with chronic low back pain is characterized by more rigid patterns. Compared to the control group, there was a decrease in the spatio-temporal parameters and kinematic parameters in patients with chronic low back pain. These findings are expected to play a role as basic data and to form a rehabilitation program for low back pain patients.

Purpose: The purpose of this study was to examine levels of pain, depression, and adjustment to military life in soldier who experienced low back pain, in order to produce fundamental data for the development of health improvement programs to prevent and manage low back pain in soldiers with low back pain. Methods: Subjects of this study consisted of 317 soldiers who had low back pain. Study instruments were Visual analog scale (VAS), the Center for Epidemiological Studies-Depression Scale (CES-D), and adjustment to military life scale. Collected data were analyzed by the SPSS Win 14.0 program. Results: Mean score of pain was 4.16 points, depression was 8.58 points, and adjustment to military life was 69.15 points. The level of pain was negatively related to adjustment to military life (r=-.241, p<.001) and positively related to depression (r=.262, p<.001). There was a negative relationship between depression and adjustment to military life (r=-.442, p<.001). Conclusion: Soldiers who had low back pain experienced higher levels of pain and depression and lower level of adjustment to military life. Therefore, further study is needed to develop and examine a nursing intervention to manage low back pain for them.

Purpose : The purpose of this study was to examine the effects of waist mobilization technique intervention for patients with chronic back pain on balance and the low back pain disability index. Methods : The subjects were 30 patients with chronic back pain. They were sampled and divided into a manual therapy group and a spinal decompression group. 15 subjects were randomly assigned to each group. Each training in this study participated for 6 weeks, 5 times a week, once a day, 15 minutes a day. Balance ability was measured with a balance analyzer, and the low back pain disability index was measured using the Oswestry Disability Index (ODI). Results : In the balance abilities, there was a significant difference in the manual therapy group compared to the spinal decompression group. In the low back pain disability index, there was a significant difference in the manual therapy group compared to the spinal decompression group. Conclusion : The analysis results of the effect of 6 weeks of waist mobilization technique intervention on the balance and low back pain disability index for patients with chronic back pain revealed that the manual therapy is more effective for static and dynamic balance ability and the low back pain disability index. In the future, we can promote independent life skills and expect a rapid recovery of patients with chronic back pain. Based on this study, further studies are needed on the effects of balance, the mechanical properties of muscle, and the low back pain disability index depending on various manual therapy techniques.

The purpose of this study was to identify the superior exercise on the reduction of low back pain, between the Mckenzie exercise and the williams exercise. 24 chronic low back pain patients were randomly divided into 3 groups (Mckenzie exercise group = 8, williams exercise group = 8, control group = 8). Each group examined using the Borg scale in a reduction of low back pain, the EMG amplitude in a stationary sit-up position and in a stationary 1000 back extension position. The Results are as follow. 1. After the training period, the Mckenzie exercise group and the williams exercise group revealed reduction of low back pain, but the control group does not revealed it. 2. After the training period, there were no significant differences on the reduction of low back pain between the Mckenzie exercise group and the williams exercise group. 3. After the training period, no groups decreased on the abdominal muscle EMG amplitude. 4. After the training period, all groups revealed no significant differences on the abdominal muscle EMG amplitude. 5. After the training period, all groups decreased on the low back muscle EMG amplitude. 6. After the training period, all groups revealed no significant differences on the low back muscle EMG amplitude. Overall, the study suggested that the Mckenzie exercise and the williams exercise achieve the same effect on the reduction of low back pain, and the fact seems to be influenced by other factors without muscular adaptation.

Objectives: This study examines the occurrence of disease resulting from low back pain and factors of working environment meaningfully influencing the occurrence of lumbago as well as analyzes '2nd Korean Working Condition Survey (KWCS)' conducted in 2010 so as to establish the prevention and improvement measures. Methods: The analysis method is that it is to compare the prevalence rate of low back pain according to working environment via odds ratio and to implement the test about the factors having the difference in working environment between low back pain group and normal group through weighted t-test. Results: As a result, it indicates that there is a meaningful difference for prevalence rate of low back pain according to age, status in employment and education level which are socio-demographical factors. The analysis in working hours shows that the period of work is a factor raising the prevalence rate of low back pain rather than weekly working hours. The analysis in the work risk factor indicates that the increase in prevalence rate of low back pain takes place to either workers with repetitive movement and continuously standing posture or those with heavy stress and emotional labour. Conclusions: Workers with low back pain have suffered from accident, depression, anxiety disorder and sleep. The factors in which the prevalence rate of low back pain decrease are to provide information on health and safety and working speed, and enough rest.

Objective: The purpose of the study was to compare the acceleration and shock attenuation (SA) of the runners with/without low back pain (LBG vs. NLBG) while running at 2.5 m/s, 3.0 m/s, 3.5 m/s and 4.0 m/s. Method: 15 adults without low back pain (age: 23.13±3.46 years, body weight: 70.13±8.94 kg, height: 176.79±3.68 cm, NLBG) and 7 adults with low back pain (age: 27.14±5.81 years, body weight: 73.10±10.74 kg, height: 176.41±3.13 cm, LBG) participated in this study. LBG was recruited through the VAS pain rating scale. All participants ran on an instrumented treadmill (Bertec, USA). Results: The LBG shows statistically greater vertical acceleration at the distal tibia during running at 3.5 m/s and 4.0 m/s and greater shock attenuation from the distal tibia to the head during running at 3.5 m/s compared with the NLBG during running (p<.05). As the speed increased, there was a statistically significant increase in vertical/resultant acceleration and shock attenuation for both groups. Conclusion: The findings indicated that the runners with low back pain (LBG) experience greater impact and shock attenuation compared with non-low back pain group (NLBG) during fast running. However, it is still inconclusive whether high impact on the lower extremity during running is the main cause of low back pain in the population. Thus, it is suggested that the study on low back pain should observe the characteristics of impact during running with individuals' low back pain experience and clinical symptoms.

Purpose: The purpose of this study was to identify effects of a strengthening program for the lower back in older women with chronic low back pain. Methods: The research design was a nonequivalent control group pretest-posttest experiment. The experimental group consisted of 16 older women and the control group, 14, all of whom had experienced low back pain for at least 3 months. The strengthening program for the lower back included lumbar stabilization exercises and education on pain management in daily living. For an 8 week period, exercises were done 3 days a week and on one day education was also given. Results: Pain and disability scores decreased significantly in the experimental group compared to the control group. Flexibility, life satisfaction and lumbar muscle strength scores increased significantly in the experimental group compared to the control group. Conclusion: Low back pain and disability can be relieved, and flexibility, muscle strength, and life satisfaction increased through a program to strengthen the lower back. It is suggested that a program to strengthen the lower back would be an effective nursing intervention for older women with low back pain.
