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.

Both flexion-based and extension-based exercises could reduce postoperative back pain and disability. However, the impact of the extension-based program was more dominant. Moreover, these exercises could increase back and abdominal muscle endurance. Therefore, prescribing such low-cost home-based exercises could be very helpful for patients with lumbar discectomy.
