Purpose: Low back pain is a common disorder experienced by approximately 90% of the population at least once in their lifetime. This study is to examine changes in the thicknesses and ratios of the deep and surficial fibers of the multifidus according to the lumbar stabilization exercise used for spinal stabilization.
Methods: Ten different lumbar stabilization exercise were implemented by 20 healthy men in random order while measuring the thickness of multifidus through ultrasound images during each exercise.
Results: The surface muscle fibers of the multifidus muscles significantly increased in the exercise method in which the arms and legs were lifted (p＜.05). But the deep muscle fibers of the multifidus muscles significantly increased in which the arms and legs were not lifted (p＜.05). The ratio of the thickness of surface muscle fibers to the total thickness of muscle fibers was higher in the exercise method in which the arms and legs were lifted (p＜.05), while the ratio of the thickness of deep muscle fibers to the total thickness of muscle fibers was higher in the hollowing and bracing exercise method in which the arms and legs were not lifted (p＜.05).
Conclusion: When lumbar stabilization exercise should be performed at clinics to strengthen the deep muscle fibers of the multifidus muscles that have larger effects on the stability of spinal segments, considering the stability of the spine, hollowing exercise methods and bracing exercise methods that do not that cause isotonic extension the spine should be appropriate.
