Purpose: This study examined the effectiveness of iliopsoas self-stretching on the hip extension angle, gluteus maximus (GM) activity, and pelvic compensated angle during prone hip extension (PHE) in subjects with iliopsoas shortness. Methods: Twenty-healthy subjects with iliopsoas shortness were recruited. Electromyography (EMG) was used to examine erector spinae (ES), multifidus (MF), GM, and biceps femoris (BF) while performing PHE. An electromagnetic tracking motion analysis device was used to measure the pelvic compensations. The pelvic compensations while performing PHE were considered to be anterior tilting and rotation. A modified Thomas test was used to monitor the hip extension angle before and after iliopsoas self-stretching. A paired t-test was used to investigate the significant difference after iliopsoas self-stretching during PHE. The level of statistical significance was set to ${\alpha}=0.05$. Results: Muscle activity of GM and hip extension angle were significantly greater after iliopsoas self-stretching compared to that before iliopsoas self-stretching during PHE (p<0.05). BF and pelvic rotation angle were significantly lower after iliopsoas self-stretching compared to that before iliopsoas self-stretching during PHE (p<0.05). The muscle activity of ES was not significantly different between PHE before and after iliopsoas self-stretching (p>0.05). Conclusion: Iliopsoas self-stretching can be effective in selectively strengthening the GM muscles with minimized pelvic compensation in subjects with iliopsoas shortness.

Background: The purpose of this study was to investigate the effect of stretching and strengthening exercise on the static flexibility and pain intensity for the iliopsoas muscle, which is one of the main reasons for the chronic low back pain. Methods: The subjects of this study were 15 male adult patients with showed 6 score or higher in the visual analogue scale(VAS) and complained of low back pain over three months who visited department of the physical therapy, KIA motors Industrial Health Center, from October, 2008 through December, 2008. Fifteen subjects were trained stretching, mat exercises and sling exercises for iliopsoas muscle at 4-5 times a week for 4 weeks. I measured the changes on the extensibility of iliopsoas muscle, static flexibility of low back and VAS between pre- and post exercise treatment. Date were analyzed using the Wilcoxon's signed rank test considering the size of the samples. Results: 1. The angle of the hip joint that showed the extensibility of iliopsoas muscle was relieved, which was significant statistically (p<.05). 2. The static flexibility was statistically significantly improved in the trunk flexion test, trunk extension test and Schober-Test (p<.05). 3. The VAS showed decrease, which is significant statistically (p<.05). Conclusion: It is believed that the exercise treatment of iliopsoas muscle has the significant effects on the improvement of static flexibility and decrease of pain intensity for the chronic low back pain patients.

PURPOSE: This study examined the relationship between lumbar instability and shortening of the iliopsoas muscles in patients with chronic low back pain. METHODS: Forty-nine patients with chronic low back pain participated in this study. The modified Thomas test was used to examine the shortening state of the iliopsoas muscle. The length of the iliopsoas muscle was measured using the hip flexion angle, and those with a flexion angle of 10° or more were classified as positive. Five subtests were used for the lumbar instability test: testing for prone lumbar instability, passive lumbar extension, anterior-posterior mobility, passive straight leg raise, and age. Those who tested positive for at least three of these tests were classified as positive for the lumbar segment instability test. RESULTS: There was a significant association between the results of the lumbar instability test and the shortening of the iliopsoas test (p < .05). After analyzing the association between the iliopsoas length test and the five lumbar instability subtests, the results of the prone lumbar instability test (p < .001) and the anterior-posterior mobility test (p < .05) showed a significant association with the iliopsoas length test. CONCLUSION: The association between lumbar instability and shortening of the iliopsoas muscles was examined in 49 patients with chronic low back pain. Patients with shortened iliopsoas muscles tested positive in the lumbar instability tests more often. Hence, the length test of the iliopsoas muscle can be used to determine lumbar instability in patients with chronic low back pain.

Restless legs syndrome(RLS) is a neurological disorder characterized by an irresistible urge to move legs to stop uncomfortable or odd sensations. We report a new approach to improve RLS using acupuncture and massage on iliopsoas Muscle. The patients who have RLS were treated by acupuncture and massage on iliopsoas Muscle. We measured 3~6 times IRLS(Korean Versoin of International Restless Legs Scale), VAS(visual analogue scale), and angle(between the legs and the table) during the treatment period. After treatment, RLS symptoms decreased, In case 1, IRLS changed 34 to 10, VAS changed 8 to 2, angle changed 20 to 5. In case 2, IRLS changed 22 to 12, VAS changed 10 to 5, angle changed 15 to 10. In case 3, IRLS changed 30 to 9, VAS changed 8 to 1, angle changed 25 to 5. Acupuncture and massage on iliopsoas muscle for RLS was effective. To effective acupuncture treatment for RLS, more research is needed.

What we want to report is the oriental medical treatment of eleven patients with lumbago. The patients had several features in common. First, the source of the lumbago was related to overdrinking or overeating, which is something like food damage(食傷) in oriental medicine. Second, they had symptoms of digestive trouble as well as lower back pain. Third, the R.O.M of lumbar spine was limited but there was no another special abnormality in physical examination. Fourth, singly they had muscular tenderness of Iliopsoas muscle and symptoms by Myofascial pain of Iliopsoas muscle was appeared. We assumed this sort of lumbago to be one due to retention of undigested food(食積) or damp-heat(濕熱) in oriental medicine, similar to Myofascial pain syndrome of Iliopsoas muscle in western counterpart. Acupuncture treatment was done to improve the digestive trobles according to oriental medical theory, and we saw the improvement in VAS score of lower back pain, degree of lumbar flexion, Iliopsoas muscle's tenderness and also digestive trobles. But an objective researches on the relation of lumbago due to retention of undigested food(食積) or damp-heat(濕熱) and myofascial pain syndrome of Iliopsoas muscle are quite lacking. However we think such a clinical approach could be useful in practices of oriental medicine increase in curative effect.

PURPOSE: By virtue of its location, the iliopsoas muscle has the potential to affect the function of the diaphragm. Therefore, the purpose of this study was to investigate the effects of passive stretching of the iliopsoas muscles on pulmonary function. METHODS: Twenty male university students participated in this study. Subjects with low back pain, negative results on the modified Thomas test, and chest breathing patterns not directly related to the function of the iliopsoas muscles were excluded from this study. A digital pulmonary function measuring device (Pony FX, COSMED Inc, Italy) was used to test pulmonary function. The test was performed three times: the first test before passive stretching, the second test 10 minutes after the first test, and the third after passive stretching. Passive stretching was performed 5 times for each of the left and right iliopsoas muscles. Passive stretching was carried out for 20 seconds followed by a 10-second break. The SPSSWIN (ver. 27.0) statistics program was used for data analysis, and the significance level was α =.05. RESULTS: Among slow vital capacity (SVC) parameters, tidal volume (VT), inspiratory reserve volume (IRV), inspiratory capacity (IC) and vital capacity (VC) improved significantly after passive stretching. Also, among the maximal effort vital capacity (MEVC) parameters, forced vital capacity(FVC) and forced expiratory volume in one second(FEV1) improved significantly after passive stretching. CONCLUSION: The results showed that among the various pulmonary function parameters measured, passive stretching of the iliopsoas muscles can improve the SVC and MEVC. Therefore, passive stretching of the iliopsoas muscles may be considered for use as a treatment method to improve pulmonary function.
