The purpose of this study was to investigate effect of type of physical therapy (spinal stabilization exercise and manual therapy) on pain index and disability index in acute and subacute patients with low back pain (LBP). 23 patients with LBP participated and were randomly assigned. Manual therapy and spinal stabilization exercise was applied for 15-minute sessions occurred 3 sessions a week, for 4 weeks. All subjects received conservative therapy for 30-minute. Visual analogue scale (VAS) and Korean version of Oswestry disability index (ODI-K) were measured before and after treatment. There was significant difference in VAS and ODI-K between before and after both treatment (p<.05). There was significant difference in change rate of VAS between manual therapy and spinal sabilization exercise (p<.05), but not in change rate of ODI-K (p>.05). Thus, it is suggested that spinal stabilization exercise is helpful to reduce pain safely in acute and subacute patients with LBP.

Objective To elucidate the effect of a 12-week horizontal vibration exercise (HVE) in chronic low back pain (CLBP) patients as compared to vertical vibration exercise (VVE). Methods Twenty-eight CLBP patients were randomly assigned to either the HVE or VVE group. All participants performed the exercise for 30 minutes each day, three times a week, for a total of 12 weeks. Altered pain and functional ability were evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI), respectively. Changes in lumbar muscle strength, transverse abdominis (TrA) and multifidus muscle thicknesses, and standing balance were measured using an isokinetic dynamometer, ultrasonography, and balance parameters, respectively. These assessments were evaluated prior to treatment, 6 weeks and 12 weeks after the first treatment, and 4 weeks after the end of treatment (that is, 16 weeks after the first treatment). Results According to the repeated-measures analysis of variance, there were significant improvements with time on VAS, ODI, standing balance score, lumbar flexor, and extensor muscle strength (all p<0.001 in both groups) without any significant changes in TrA (p=0.153 in HVE, p=0.561 in VVE group) or multifidus (p=0.737 in HVE, p=0.380 in VVE group) muscle thickness. Further, there were no significant differences between groups according to time in any of the assessments. No adverse events were noticed during treatment in either group. Conclusion HVE is as effective as VVE in reducing pain, strengthening the lumbar muscle, and improving the balance and functional abilities of CLBP patients. Vibrational exercise increases muscle strength without inducing muscle hypertrophy.

The objective of this research was to examine the effects of lumber stabilization exercise and a general physiotherapy program for caregivers with chronic low back pain. Sixteen people participated in this study and were randomly assigned to two groups for either lumbar stabilization exercise or for general physiotherapy, respectively. The experiment was performed for eight weeks. To examine the general as well as the medical characteristics of the participants, the following measurements were used: Visual Analogue Scale (VAS); Oswestry Disability Index (ODI); Back Performance Scale (BPS); Roland - Morris Disability Questionnaire (RMDQ); and Beck Depression Index (BDI). To compare the general and medical characteristics of the participants in the two groups, an independent t test were used. During the experiment, a paired t test was conducted to determine whether there was a significant difference in the values of VAS, ODI, BPS, RMDQ, and BDI before and after the experiment. To examine the difference in the VAS, ODI, BPS, RMDQ, and BDI values in the two groups, ANCOVA was used with pre test values as a covariate. According to the test results, in the lumbar stabilization exercise group, the VAS, ODI, BPS, RMDQ, and BDI values showed a statistically significant difference before and after the test (p<.05). In comparison, in the general physiotherapy program group, only the ODI and BPS values showed a statistically significant level of improvement. Regarding the degree of improvement, participants in the lumbar stabilization exercise group showed statistically significant progress compared to those in the general physiotherapy group. In summary, lumbar stabilization exercise is regarded as more effective than general physiotherapy for treating caregivers with chronic low back pain. In future studies, it will be useful to expand the research and to examine the long term effects of lumbar stabilization exercise on workers.

Purpose: This study was to examine lateral abdominal muscle activation during maximum expiration exercise between healthy and chronic low back pain(CLBP) patients. Methods: The subjects were 16 CLBP patients and 16 healthy people between the ages of 22 and 53. The thickness of the abdominal muscles was measured using ultrasonography(LOGIQ Book XP, GE, USA). We instructed the subjects how to perform the exercises and measured changes in thickness of the transversus abdominis(TrA) and internal oblique(IO) muscles during the maximum expiration. The main outcome variables were the ratios of the TrA and IO thickness during the exercise versus in the relaxed position(TrA and IO activation ratios). Results: There were significant differences between CLBP patients and healthy subjects for TrA in the relaxed position. However there was no difference in the ratio of change in the muscle activity(TrA, IO). Conclusion: These findings, CLBP patients exhibited atrophy of the TrA muscle, but voluntary TrA muscle activation was similar to that of the normal subjects. Therefore, this exercise could be used during core strengthening in CLBP patients.

This study was conducted to measure and analyze the changes in paraspinal muscles of acute and chronic low back pain patients using MRI, and to provide clinical basic data for diagnosis and treatment for low back pain. For this purpose, 20 patients with acute low back pain frome August 2012 to January 2013 which occurred within 12 weeks, and 20 patients with chronic low back pain that progressed over 12 weeks, were chosen as subjects, and their MRI measurements were compared with one another. As a result, in relation to in the fatty degeneration ratio of the left spine and right spine, there were significant differences in erector spinae and multifidus(p<.001), and in relation to the Fat Infiltration ratio between all the groups, there were significant differences in psoas major, erector spinae and multifidus between the acute low back pain patient group and the chronic low back pain patient group(p<.001). In the post-hoc test, multifidus and erector spinae in the acute low back pain group and chronic low back pain group showed the highest Fat Infiltration ratio. The serious Fat Infiltration of multifidus and erector spinae in the chronic low back pain group led to weakened strength of muscles that stabilize the spine. In conclusion, it is considered that this study would present important data and basis in making acute and chronic low back pain patients pay more attention to multifidus and psoas major during rehabilitation exercise, and selecting a rehabilitation exercise program.

This study performed a virtual reality exercise program for self-back pain control of industrial workers with chronic back pain and analysed their physical function and health-related quality of life relating to industrial chronic back pain. The subjects of the study were thirty chronic back pain patients working for K company and were divided into Nintendo Wii Sports Group made of 15 subjects and Physical Therapy Group made of 15. As variables for physical functions, back strength, flexibility, balance and pain were measured and for the health-related quality of life, SF-36 of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that balance and pain of the both groups were improved statistically significantly. Physical functions of the Nintendo Wii Sports Group were improved statistically significantly in comparison with those of the Physical Therapy Group. The health-related quality of life was improved statistically significantly only for the Nintendo Wii Sports Group. In conclusion, it is suggested that as the virtual reality exercise program had a positive influence on chronic back pain of industrial workers, it should be considered as a home exercise program for back pain control.
