Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

LBP individuals

People who suffer from pain in the lower back area.

MSK ultrasonograpy

Intervention Type OTHER

MSK ultrasonography was used to measure the thickness of diaphragm muscle in supine and sitting position and in a relaxed and in a contracted state.

sitting Functional and Lateral Reach Test

Intervention Type OTHER

Sitting reach tests were used to measure the stability limits of the trunk in different directions. Functional reach test is for testing the forward direction and lateral reach tests are for testing the right and the left directions.

asymptomatic individuals

People who has no low back pain in the patient history.

MSK ultrasonograpy

Intervention Type OTHER

MSK ultrasonography was used to measure the thickness of diaphragm muscle in supine and sitting position and in a relaxed and in a contracted state.

sitting Functional and Lateral Reach Test

Intervention Type OTHER

Sitting reach tests were used to measure the stability limits of the trunk in different directions. Functional reach test is for testing the forward direction and lateral reach tests are for testing the right and the left directions.
