The effect of stabilization exercises on lumbar lordosis in patients with low back pain

Background and Purpose: There is a hypothesis that restoring the lumbar lordosis will increase a patient's voluntary muscular strength and decrease back pain symptoms. This study aimed to evaluate the effects of stabilization exercises on lumbar lordosis and functional improvement. Methods: Thirty-two patients with chronic low back pain (LBP) were recruited through simple nonprobability sampling for this double-blind, randomized clinical trial, performed at the Razmejo-Moghadam Physiotherapy Clinic, Zahedan University of Medical Sciences. Participants were randomly assigned to either stabilization exercise group ( n  = 16) or control group ( n  = 16). Before and after intervention, we assessed pain (ordinal) through the McGill Pain Questionnaire, disability (ordinal) with the Oswestry Disability Index (ODI), and lumbar curve (degree) with flexible ruler. Twelve sessions daily exercise program was performed for both groups.  t -tests were used for data analysis ( P Results: Amount of lumbar curve was significantly changed after training in both groups ( P P P  > 0.05). However, pain score and Oswestry score showed significant differences between two groups after intervention ( P Conclusion: The results showed that both lumbar stabilization and routine physiotherapy cause decreasing in pain, disability, and change lumbar lordosis in patients with chronic LBP. Therefore, lumbar curve evaluation and therapeutic exercise for restoration lumbar curve were recommended.
