简要总结
Pathomechanism of nonspecific low back pain is not clear for the researchers yet. Our aim is to evaluate the function of one of the stabilizer muscles of the low back area. Diaphragm's postural function is evident. However, we do not understand its changes of function in low back pain. Postural function of diaphragm was screened in supine position and in sitting too in a relaxed and in a contracted state. The thickness of diaphragm was measured and contraction ratio was calculated. Additionally, the stability limits of the trunk were measured. We were curios about the differencies in contraction ratio between asymptomatic and low back pain individuals.

Pathomechanism of nonspecific low back pain is not clear for the researchers yet. Our aim is to evaluate the function of one of the stabilizer muscles of the low back area. Diaphragm's postural function is evident. However, we do not understand its changes of function in low back pain. The postural function of diaphragm was screened with Zonare Zone Ultrasound System in supine position and in sitting too in a relaxed and in a contracted state. The thickness of diaphragm was measured by using an elecric caliper of the ultrasound device and the contraction ratio was calculated. Additionally, the stability limits of the trunk were measured with sitting functional reach and sitting lateral reach tests. We were curios about the differencies in contraction ratio between asymptomatic and low back pain individuals.

结局指标
主要结局
sitting Functional and Lateral Reach Test
时间窗: 5 min
Special functional tests for testing the stability limits of the trunk. These are measured in sitting position, with the feet on the ground and without any support. The induvidual has to lean forward/right/left directions with forward stretched arms. We calculated the distance between the start and end positions of the fingers.
MSK ultrasonography
时间窗: 20 min
An imaging procedure that allows doctors, physiotherapist to see muscles, joints, and more. For diagnosing muscle tears/strains, nerves, and arthritis. Physical therapy or injection of medicine may be next step. Involves radiology and center for musculoskeletal care. In our study, the thickness of diaphragm muscle was measured in supine and sitting positions. Its contraction ratio was calculated, based on the relaxed and the contracted states of the muscle.
