요부안정화운동에 따른 산업체 만성요통환자의 운동능력 및 통증의 변화

Abstract

This study was conducted on 18 people from K-company rehabilitation center who were suffering from chronic low back pain, and randomly divided into 9 people of the lumbar stabilization exercise group of the stable ground and the rest of 9 people of the lumbar stabilization exercise group of the unstable ground and the lumbar stabilization exercise was done 5 times a week, for 6weeks to find out how the lumbar stabilization exercise on the ground-conditional difference can interact with the industrial workers' pains and their exercise capacity. And the muscle strength, the endurance, the flexibility, and balancing ability were measured for the time; before the exercise, after 3 weeks and after 6 weeks by using NURYTEC company measuring apparatus and the pain levels were revaluated in the same measurement method with visual analogue scale(VAS). In the muscle strength measuring test according to the lumbar stabilization exercise, the muscle strength of the two groups increased steadily for the time; before the exercise to after 3 weeks and after 6 weeks, however as a result of the repeated measured ANOVA they showed no significant difference (p>.05). In the endurance measuring test according to the lumbar stabilization exercise, both groups showed the increased endurance for the time; before the exercise, after 3weeks and after 6weeks however there was no significant difference as a result of the repeated measured ANOVA(p>.05). In the flexibility measuring test according to the lumbar stabilization exercise, the two groups flexibility gradually increased for the time; before the exercise, after 3 weeks and after 6 weeks but there was statistically no significant difference as a result of the repeated measured ANOVA(p>.05) and in the balance ability measuring test according to the lumbar stabilization exercise, the balance ability of the two groups improved gradually and as a result of the repeated measured ANOVA, there were significant differences statistically between the periods and between the groups (p<.05), in the pain level measuring test according to the lumbar stabilization exercise, the pain of the both groups were relieved gradually for the periods; before the exercise, after 3 weeks and after 6 weeks, as a result of the repeated measured ANOVA, there were significant differences in the statistics between the change of the pains for the two groups in the state of the revised time consequences(p<.05). As a result, chronic low back pain of the industrial workers are not only the pain related to muscular functions such as muscle strength, endurance or flexibility but the industrial low back pain is also affected by the leaned muscular balance followed by the body balance decrease and in conclusion, the lumbar stabilization exercise on the unstable ground increases more balance capacity than on the stable ground so that it reduces the load of the muscles around the spine. Based on this conclusion, besides the industrial workers suffering from chronic low back pain, the constant researches on various people from various environments are necessary later on.
