The effect of repeated flexion-based exercises versus extension-based exercises on the clinical outcomes of patients with lumbar disk herniation surgery: a randomized clinical trial.

Background: Valuable impact of postoperative exercises on the clinical outcomes of patients with lumbar discectomy has been demonstrated. However, there is a lack of consensus on the best kind of postoperative exercises. This study aimed to evaluate the impact of the early postoperative flexion-based and extension-based exercises on the clinical outcomes of patients with lumbar discectomy.
