Purpose: This study aims to examine the pain, muscle characteristic, Flexion-Relaxation Phenomenon to the hamstring flexibility. Methods: This study has as its subjects 105 Chronic Low Back Pain patients and divides them into the group (HHF n=52) with the normal length of hamstrings according to AKE test and the group (HLF, n=53) tending to have shortened hamstrings. AKE (active knee extension) Test was conducted to evaluate the degree of hamstring flexibility. And to examine the pain, muscle characteristic, Flexion-Relaxation Phenomenon it was compared and analyzed by using the VAS, myotonePRO, SEMG Results: HHF showed more significant difference than HLF in the analysis on the muscle characteristic (p<.05). Conclusion: According to the analysis, the shortening of hamstrings is the factor that affects the muscle characteristic but Chronic pain, Flexion-Relaxation Phenomenon not affects
