Randomized Controlled Trial Comparative Study Clinical Trial
The effects of spinal flexion and extension exercises and their associated postures in patients with acute low back pain.
A prospective randomized clinical trial compared the effects of flexion and extension back exercises and postures among soldiers with acute low back pain. ⋯ There was no difference for any outcomes between the flexion or extension exercise groups. However, either exercise was slightly more effective than no exercise when patients with acute low back pain were treated.
