Background: In patients with lumbar spinal stenosis (LSS), lumbar flexion exercise (LFE) is considered a standard therapeutic exercise that widens the space between the spinal canal and intervertebral foramen. However, some researchers have reported that lumbar extension exercise (LEE) may improve lumbar pain and functional ability in patients with LSS. Although exercise intervention methods for patients with LSS have been widely applied in clinical settings, few studies have conducted comparative analysis of these exercise methods. Objects: This study aimed to compare the effects of LFE, LEE, and lumbar flexion combined with lumbar flexion-extension exercise (LFEE) on pain, range of motion (ROM), pelvic tilt angle, and functional gait ability in patients with LSS. Methods: A total of 30 patients with LSS, LFE (n1=10), LEE (n2=10), and LFEE (n3=10) were assigned to each of the three exercise groups. The numerical pain rating scale (NPRS), modified-modified schober test (MMST)-flexion, MMST-extension, pelvic tilt inclinometer, and 6-minute walking test (6MWT) were measured. Results: After the intervention, statistically significant differences were observed in the NPRS (p=.043), MMST-flexion (p<.001), MMST-extension (p<.001), and 6MWT (p=.005) between groups. According to the post hoc test, the NPRS was statistically significant difference between the LFEE and LEE groups (p=.034). The MMST-flexion was statistically significantly different between the LFE and LEE (p=.000), LFE and LFEE (p=.001), and LEE and LFEE (p=.001) groups. The MMST-extension was statistically significantly different between the LFE and LEE (p<.001), LFE and LFEE (p=.002), and LEE and LFEE (p=.008) groups. The 6MWT was statistically significantly different between the LFE and LFEE (p=.042) and the LEE and LFEE (p=.004) groups. Conclusion: This study suggested that LFEE was the most effective exercise for pain and functional gait ability in patients with LSS, LFE was the most effective exercise for lumbar flexion ROM, and LEE was the most effective exercise for lumbar extension ROM.

Objectives: The Purpose of this study was to investigate the effects of chiropractic treatment and low back exercise on lumbar lordosis angle, gravity line, range of motion, and pain degree of university students who are taking a commuter bus at least 4 hours of round trip. Methods: A group of 15 participants received chiropractic treatment around the lumbar spine region twice per week for 8 weeks. Another group of 15 participants were treated with low back exercise three times per week for 8 weeks. Results: In the present results, both chiropractic treatment and low back exercise did not affect the change of lumbar lordosis. However, chiropractic treatment also significantly improved the range of the lumbar motion, including Flexion, Extension, Right Lateral Flexion and Left Lateral Flexion(p<0.05), and consequently decreased the pain degree. Low back exercise significantly moved the lumbar gravity line to almost normal scale, and improved the range of the lumbar motion, including Flexion, and Right Lateral Flexion (p<0.05), resulting in the reduction of pain degree, although both chiropractic treatment and exercise treatment did not change the lumbar lordosis angle at the statistically significant. Conclusions: From these results, it can be inferred that chiropractic treatment might be beneficial to alleviating the low back pain of the university students using a commuter bus by improving the range of lumbar motion or stabilizing the lumbar gravity line.

Purpose: Muscle fatigue affects proprioception, and it causes problems in spinal stability. The purpose of this study was to examine the effect on the accuracy of reproducing the lumbar angles before lumbar exercise and after fatiguing isokinetic lumbar exercise. Methods: Thirty healthy adults participated in this study. Before induction of fatigue by exercise, the proprioception was measured by Biodex. Lumbar positions were passively maintained on stimulation position ($25^{\circ}$ flexion and $25^{\circ}$ extension), and back to the starting position. Subjects actively repositioned the remembered stimulation position, and error degrees between the stimulation position and reposition were measured. Using an isokinetic device at $120^{\circ}$/sec of velocity of angle lumbar flexion/extension exercise resulted in muscle fatigue. The post-fatigue proprioceptive position sense was used in the same way as in pre-fatigue measurement. Results: Means of position sense of pre-fatigue were $2.19{\pm}1.97$ on flexion angle, and $5.04{\pm}2.84$ on extension angle. After exercise induced fatigue, means of position sense were $2.37{\pm}1.83$ on flexion angle, and $4.93{\pm}2.57$ on extension angle. Results of this study showed significant differences of lumbar proprioceptive position sense between pre- and post-fatigue. Conclusion: Lumbar proprioception sense in active repositioning in flexion and extension was affected in the presence of muscle fatigue. Therefore, it should be noted that therapeutic exercise for patients with abnormal proprioceptive sense or elderly people must be performed with care because muscle fatigue can cause secondary damage.

The "WuQinXi" exercise, one of the medical Qi-gongs, is an exercise maximizing human's self healing power and has been confirmed to be effective significantly at several modern researches. There are many exercise therapies in western medcine, such as Willams's flexion exercise, Mckenzie's extension exercise, vertebral stabilization exercise and so on. However, there isn't a special exercise therapy which can be applied for medical practice in oriental medicine. So we selected 24 motions which are related with lumbar movements from 3 type "WuQinXi" exercises ; 20 mode, 30 mode, and 40 mode. And then, we classified them according to lumbar movements as flexion, extention, lateral bending and rotation, and also functions as stabilization and rubbing. Next, with these classifications, we assorted them by kinds of lumbar spinal disease as HIVD(herniation of intervertebral disc), spinal stenosis, spondylolysis and spondylolisthesis, facet joint syndrome, compression fracture and spondylosis. We expect that "WuQinXi" exercise be a exercise therapy for lumbar spinal disease at an oriental medical clinic in this way. Oriental medical doctors will be able to teach easily patients "WuQinXi" exercise's motions at clinic, depending on kinds of lumbar spinal disease each patient suffers from. We plan to study the effect of "WuQinXi" exercise by comparing patients who do the "WuQinXi" exercise with the patients who do the western medical exercise therapy.

The purpose of this study was designed to find out the effectiveness of vertebral segment instability, muscle fatigue response on lumbar spine after apply lumbosacral stabilization exercise program to 4 patients with chronic low back pain and for 12 weeks. In this study, the lumbar spine motion with blind by MedX test machine and the difference of instability to lumbar vertebra segments in flexion, extension test of standing position and spinal load test(Matthiass Test) by Spinal Mouse. The stabilization exercise program was applied 2 times a week for 12 weeks in hospital and 2 times a day for 20 minutes at home. The results of the present study were as follows: 1. Instability test of lumbar vertebra segment is 2 type differential angle test between vertebrae segment and loading test of spine(matthiass) by Spinal Mouse. It appeared to improve stability of segments in sagittal plane after applying program. So lumbar spine curve increased lordosis toward anterior and was improved of the lumbar spine flexibility in flexion and extension. Specially, in matthiass test, (-) value was increased between lumbar vertebra segment when was the load on spine. And so applying stability improved after program. 2. Fatigue response test(FRT) results, in male, was raised muscle fatigue rate during increase weight, on the other hand female appeared lower than male. As a results, lumbosacral stabilization exercise was aided to improvement of lumbar spine vertebra segments stabilization. Spine instability patients will have a risk when in lifting a load or working with slight flexion posture during the daily of living life and it is probably to increase recurrence rate. Thus, not only lumbar extension muscle strength but also stability of vertebra segments in lumbar spine may be very important.
