简要总结
Brief Summary: Low back pain is very common problem in all the developed countries and affects children to elderly. Based on the etiology the low back pain is divided into two type: nonspecific and specific low back pain. If the pathological reason is known it is defined as specific and if the reason for the pain is unknown it is defined as nonspecific low back pain. The postulated reason for nonspecific low back pain is the segmental instability of the lumbar spine. Diaphragm muscle has a role in maintaining the segmental stability. The aim of this study to reduce the severity of the low back pain with improving the stability of the lumbar spine by using diaphragm training.
详细描述
The study is a randomized controlled trial. The participants are divided randomly into two groups. One of the groups take part in a complex training which contains stretching, strengthening, mobilizing exercises and proprioceptive training and this training is completed by diaphragm strengthening exercises. This group is defined as diaphragm training group. The members of the diaphragm training group use the POWERbreathe Medic Plus device. Opposed to the diaphragm training group the members of the control group take part only in the complex training without strengthening the diaphragm muscle. The pain intensity is assessed by Visual Analogue Scale and the diameter of the stabilizer muscles' belly is measured by B-mode ultrasound examination, using Zonare Z.One Ultrasound System (Mountain View, CA, USA). The thickness of the transversus abdominis muscle, the lumbar multifidus muscle and the diaphragm muscle is assessed in two different positions: during lying and during sitting position with weightlifting. The muscles are measured in two different states: a relaxed and a contracted state. Functional tests and a balance platform (NeuroCom) are used to measure the stability, and the function of the diaphragm is assessed by using a POWERbreathe KH2 device.

结局指标
主要结局
Pain assessed by Visual Analogue Scale (followed by its scale information in the Description)
时间窗: 8 weeks
The severity of the pain is measured with Visual Analogue Scale (VAS) before and after the intervention. This is a semi-objective, self-report device that is used extensively to measure such complaints as pain. The sclale is a 10 cm line. The scale is anchored by 'no pain' (0 score) and 'worst imaginable pain' (score of 10). Therefore the higher values represent a worse outcome. When using the Visual Analogue Scale, the participants had to mark on a 10 cm long line the average severity of lumbar pain and we measured the distance of their mark from the zero point in cm-s.
Thickness of the stabilizer muscles' belly
时间窗: 8 weeks
The thickness of the stabilizer muscles's belly is measured with an ultrasound examination (Zonare Z.One Ultrasound System). The assessed muscles are transversus abdominis muscle, diaphragm muscle and lumbar multifidus muscle before and after the intervention.
