The purpose of this study is to examine the effect of exercise for strengthening hip abductor on patients with chronic low back pain, who having lumbar instability. Among 78 patients having chronic low back pain, 38 patients showing positive in 3 items or more for 5 tests regarding lumbar instability are classified as patients having lumbar instability. 38 subjects are randomly allocated into two groups. One is an experimental group (EG), where exercise for strengthening hip abductor strength as well as exercise for lumbar stability are instructed and the other group, a control group (CG), where only lumbar stability exercise is instructed. All exercises are taken place 3 times a week during 4 weeks.
Before intervention, A 100㎜ visual analog scale(VAS), the Korean version of the Oswestry disability index(KODI), fear-avoidance beliefs questionnaire(FABQ), and muscle strength in hip abductor are tested for two groups. After 4 weeks of intervention, all 4 indexes are reevaluated
Independence sample t-test is conducted to evaluate the effect of intervention on VAS, KODI, FABQ, and hip abductor strength and repeated ANOVA is measured to compare the difference in lumbar instability between two groups according to the intervention.
Whether two groups are different in regards to lumbar instability level according to the intervention, are tested using statistics, wilcoxon signed-ranks, with significance level .05.
The conclusions are as following.
For all of the two groups, VAS and KODI are significantly decreased after intervention (p<.05) and levels of the EG are more decreased than the levels of CG, showing interactive effects between EG and CG.
For all of the two groups, FABQ is significantly decreased after intervention but there is no significant difference between two groups.
For all of the two groups, lumbar instability is significantly decreased after intervention.
For all of the two groups, hip abductor strength are significantly increased after intervention (p<.05) and muscle strength in hip abductor of the EG is more increased than level of CG, showing interactive effects between EG.
According to this study, combining hip abductor strengthening exercise with lumbar stability has better effects on lumbar stability for patients with chronic low back pain, than only lumbar stability exercise does.
Therefore it is recommended that patients showing high lumbar instability among patients with chronic low pack pain should be instructed to exercise hip abductor strengthening exercise concurrently.
