in light of provided progresses in ultrasound measurements of lateral abdominal muscles, an important role for these muscles, particularly transverse abdominis (tra) muscle in stability of the spine has been suggested. some authors have found significant correlations between body mass index (bmi) and thickness of these muscles. the aim of this study was to examine possible association between d...
Background: Some studies show that frozen shoulder is due to the pathologic changes in the muscles around the shoulder. Measurement of the ultrasonic thickness of a muscle is a method for measuring the muscle changes. There is no study about the reliability of measurement of the muscle’s ultrasonic thickness around the shoulder in patients with frozen shoulder. The present study aims to invest...
conclusions our results indicate that changes in muscle thickness and echo intensity are induced by different inward pressures of the transducer during us. when using a technique that involves a handheld transducer, the examiner should attempt to maintain consistent inward pressure of the transducer during us, to quantify the minimal change of the rf mass and composition. results muscle thickne...
Background: Rotator cuff injuries are the most common causes of shoulder pain and supraspinatus muscle is usually involved. Clinical tests are available and inexpensive tools for assessment of shoulder dysfunctions. The empty can (EC) and full can (FC) tests are considered as shoulder gold standard tests. Recently, hug up (HU) test has been developed to assess the supraspinatus. So far, no ultr...
introduction: according to the importance of the back extensor muscle strength in postmenopausal women, this study aimed to determine the relationship between strength and changes in the thickness of back extensor muscles during isometric contraction in healthy and osteoporotic postmenopausal women. material and methods: 42 volunteer postmenopausal women according to their bone mineral density ...
Objective: In a non-experimental, case-control study the abdominal muscles activities during abdominal hollowing exercise in supine and four points kneeling position were investigated in males suffering from non-specific chronic low back pain compare with healthy volunteers. Materials & Methods : Twenty males suffering from non-specific chronic low back pain (mean age 39.9 years) and twenty ...
background: forward head posture (fhp) is recognized as a common postural disorder of modern societies. increase in anterior cervical convexity and anterior displacement of the line of gravity of head in individuals with fhp is assumed to result in altered moment arms and muscle activity on cervical spine. measurement of muscle thickness seems to be an appropriate index for muscle activity. thi...
Background and purpose: One of the most common postural disorders in today’s societies is the forward head posture (FHP) that is associated with numerous musculoskeletal complications. Considering sternocleidomastoid attachments to the neck, it seems that it would be negatively influenced by such postural deviations. The aim of this study was to compare the sternocleidomastoid muscle thic...
Background: The transverse abdominis (TrA) muscle is one of the most important muscles that contribute to the stability of the lumbar spine. Strengthening of trunk muscles that have a significant role in trunk stability is very important in the field of professional sport, sport medicine and rehabilitation of patient with low back pain (LBP). Identifying the exercises that can improve the stren...
Background and purpose: Middle Trapezius Muscle (MTM) is a key muscle in maintaining postural stability of the shoulder but it has received less attention in research. This study aimed to measure the ultrasonic thickness of the MTM in non-athlete healthy young men. Also, inter-rater repeatability in measuring ultrasonic thickness of this muscle was calculated. Materials and methods: A fundam...
