[Purpose] The purpose of this study was to determine the effects of the flexion-distraction technique and drop technique on the straight leg raising angle and intervertebral disc height of patients with an intervertebral disc herniation. [Participants and Methods] Thirty patients with herniated intervertebral discs were divided into either an experimental group (n=15), who underwent flexion-distraction and drop techniques, or a control group (n=15), who obtained spinal decompression therapy. Both groups were treated three times per week for eight weeks. [Results] An intragroup comparison showed that the straight leg raising angle and the intervertebral disc height significantly increased in both groups. But it was not significantly difference in the intergroup comparison. [Conclusion] The flexion-distraction technique and the drop technique may serve as effective interventions for the straight leg raising angle and intervertebral disc height in patients with intervertebral disc herniations.
