A few studies investigating lumbar ROM, lumbar extension strength, and pain degrees of patients after lumbar microdiscectomy due to herniated intervertebral disc (HIVD) have been reported in the literature. The purpose of this study was to investigate rehabilitation exercise (RE) programs on lumbar ROM (sit-&-reach, trunk extension, lateral bending), lumbar extension strength, and pain degrees after 12 weeks. Subjects were 30 patients who underwent lumbar microdiscectomy with a minimum one year of follow-up were randomly selected. They were randomly classified with RE (n=14; male 7, female 7) and non-RE (n=16; male 8, female 8) groups. We measured lumbar ROM from sit-&-reach, trunk extension, and lateral bending tests, lumbar extension strength from MedX machine, and pain degrees from pain scale invented by Taylor, Hallett, and Flaherty (1981). Statistical analysis was performed using independent t-test and paired t-test. Results are as follows; First, there were significantly increased in ROMs of sit-&-reach, trunk extension, and left or right lateral bending in RE groups after 12 weeks. Also the ROMs of RE were significantly different to those of non-RE after an experiment. Secondly, there were significantly increased in lumbar strength of isometric back extension tests which had 7 angles, 0-72°, in RE groups after 12 weeks. Also the lumbar strength of RE were significantly different to those of non-RE after an experiment. At last, there were significantly decreased in pain degrees in all groups. However, the pain degrees of RE were more declined than those of non-RE. The results suggested that rehabilitation exercise for patients operated by HIVD can furnish positive effect on ROM, back strength, and pain after 12 weeks.
