Object: postoperative treatment of herniated intervertebral disc with stability exercises. Problem: degeneration of the intervertebral disc from a combination of factors can result in herniation. Disk herniation is the protrusion of the gelatinous material of the disk (nucleus pulposus) through the annulus fibrosus (Fardon & Milette, 2001). The presence of pain, radiculopathy and other symptoms depends on the site and degree of herniation. Many treatment modalities have been suggested for lumbar disc herniation, but studies often provide conflicting results (Humphreys & Eck, 1999). Postoperative treatment is very important. Doctor B.Spakauskas with co-authors (2002) says that after operative treatment condition of patient is getting worse. Hypothesis: back stability exercises applied in postoperative herniated disc period using stabilizer should improve endurance of lumbar spine muscles more than applying traditional exercises. The aim of this study was to evaluate effectiveness of back stability exercises in postoperative herniated intervertebral disc period. The tasks: to evaluate static endurance of trunk muscles, strength of hip, calf and foot muscles and low back pain before and after applying back stability exercises; to evaluate static endurance of trunk muscles, strength of hip, calf and foot muscles and low back pain before and after applying traditional (stretching, strengthening) exercise program; to determine which exercise program had better effect on...
