بررسی تأثیر تمرینهای فعال ثبات دهنده ستون فقرات بر عملکرد عضلات کمر در صفحه ساجیتال در افراد سالم

Musculoskeletal disorders which are introduced with back pain are now the most common cause of chronic incapacity in industrialized countries. One of the important causes of low back pain is, spinal instability. A recent focus in the physiotherapy management of patients with back pain has been the active spinal stabilization exercises of muscles surrounding the spine considered to provide dynamic stability and fine control to the lumbar spine with increasing endurance and coordination of spinal stabilizer muscles. On the other hand many studies have found that inadequate strength and endurance of the back muscles are significant risk factors and symptoms for low back pain. The aim of the current study was to evaluate the effectiveness of specific stabilizing exercises on the lumbar muscle performance in saggital plane in normal subjects with Isostation B200 and clinical endurance tests. In a randomized clinical trial(RCT) 30 young healthy females were assigned randomly to case and control groups. The case group underwent a 4 week specific exercise program. After intervention the case group showed a statistically significant increase in strength and endurance variables in all tests, but after 4 weeks follow up, strength decreased significantly. Improvement in trunk muscle strength and endurance after spinal stabilization training suggests that these exercises can be the best choice for low back pain. Key Words: 1) Active spinal stabilization exercise 2) Trunk muscle performance 3) Isostation B200
