Efficacy Comparison of the Exercises Based on the Lumbar Extension and Flexion in Chronic Low Back Pain
This study is to compare the efficacy of exercises based on the lumbar extension and flexion
 on the pain relief and the prevention of pain recurrence in chronic low back pain patients.
68 people that meet the inclusion criteria on screening test are assigned to one of two
 groups by randomization. Each of the group learns one of the exercises based on the lumbar
 extension or flexion for four weeks. The main outcome variables are measured and compared
 respectively in baseline, immediately after the education, 3, 6, 12, 24 months after the
 enrollment. Finally lumbar extension exercise is verified whether it is more effective than
 the lumbar flexion exercise on the pain relief and the prevention of pain recurrence in
 chronic low back pain patients.
