Aims and Background: Non-specific low back pain has direct impact on quality of life, active days at work and healthcare cost. The purpose of this investigation was to study the relationship between lumbar lordosis and lumbar range of motion with non-specific low back pain. Methods and Materials: 50 students of kharazmi University (mean age :24 years, mean weight: 75.72 kg, mean height :180.5 c...

 Aims and background: Muscle trigger points are one of the main sites of chronic pain in the musculoskeletal system. The activity of the trigger points of the quadrates lamborum muscles are a very common cause of low back pain. Therefore, the purpose of this study was to investigate the effect of Physical therapy with and without Positional Release Techniques on the pain, disability and range o...

Introduction: Lumbar segmental instability is one of the subgroups of non specific chronic low back pain and it seems that 30-40% of patients with LBP suffer from lumbar segmental instability. Pain intensity, functional disability and reduced muscle endurance are common in such patients. The aim of this study was to evaluate the effects of stabilization exercise on pain, functional disability...

Objective: Accurate assessment of lumbar range of motion is of great value for both evaluating lumbar functions and monitoring treatment progress. Recent research indicates that there is no general consensus on the most valid and reliable method of measuring spinal range of motion. The purpose of this study was to determine the intra-rater reliability of lumbar flexion and extension measurement...

Purpose: Regarding the high prevalence of low back pain in various communities and the need to determine an appropriate treatment plan for these patients, examining their functional limitation and disability level is of utmost importance. In this regard, one of the important indicators is Lumbar range of motion. Measurement of the range of motion is a common and appropriate method for determini...

Background: The changes in motor control after the use of a supportive belt can contribute to the understanding of its effects on performance. The aim of this study is to quantify motion pattern values relative to the spinal column during the use of a lumbosacral belt.Methods: For fifty healthy female volunteers, the range of motion, maximum isometric torque and changes of phase angle of maximu...

Background: Low back pain (LBP) is a one of the most common symptoms of vertebral column diseases. Spinal muscles have a outstanding role in maintaining vertebral column function in daily life. But proper function and motion of hip and knee joints also has an important role in performing smooth, fine and nonstressed movements of lumbar spin. Where as accurate and fine motions of hip and knee jo...
