OBJECTIVE The purpose of this study was to determine the inter-rater reliability of ultrasound imaging for assessing trunk muscle morphologic characteristics at rest and while contracted among different pairs of novice raters. The secondary purpose was to compare 3 different measurement techniques for assessing lateral abdominal muscle thickness. METHODS A single-group repeated measures relia...

To establish more accurate equations for estimating the moment arm length and cross-sectional area of the erector spinae and rectus abdominis muscles, the effects of height, weight and age on those muscles were analyzed by using a high-order polynomial equation. Data on the moment arm length and cross-sectional area at L3/4 were obtained from MRI images of 152 males and 98 females. The statisti...

[Purpose] The purpose of this study was to investigate the relationship between muscle activity and gait function following aquatic trunk exercise in hemiplegic stroke patients. [Subjects and Methods] This study's participants included thirteen hemiplegic patients (ten males and three females). The aquatic therapy consisted of administering concentrative aquatic therapy for four weeks in a ther...

Diltiazem, a calcium channel blocker was studied to observe its effects on the acetylcholine contractile responses of isolated frog rectus abdominis muscle. This response was modified in a dual manner i.e., initial potentiation, followed by inhibition. Diltiazem may not have anticholinesterase like mechanism, as it potentiated the responses to both acetylcholine and succinylcholine. Rectus musc...

This study evaluated changes in deep trunk muscle thickness and lower extremity activities during bridge exercises with the abdominal drawing-in maneuver. Bridge were conducted on an unstable surface at different knee flexion angles (60º, 90º 120º), aim of identifying more effective for exercises. included 21 healthy adults, aged 20–27 years. Biceps femoris (BF), rectus abdominis, activity was ...

Repairing large incisional hernia with abdominal wall reconstruction is a technically challenging problem for surgeons. We report our experience of large midline incisional hernia which was repaired successfully with components separation technique. A patient with incisional hernia, 35 × 20 cm in size, underwent operation following standard components separation technique. The aponeurosis of th...

In recent years, with the continuous development and validation of new visualization, ultrasound-guided peripheral trunk block becomes more mature has a extensive broader implementation scope in clinical anesthesia. Based on this, we reviewed summarized literature nerve include: paraspinal block, retrolaminar plane erect spinal muscle, transverse convex to pleural midpoint trapezius muscle ante...

[Purpose] This study investigated and compared the discomfort experienced during car egress with the car door opened at different angles and muscle activation in drivers with hemiplegia following stroke and non-disabled drivers. [Subjects and Methods] The participants were five drivers with hemiplegia and five non-disabled drivers. The discomfort experienced during car egress was measured using...

Rectus sheath hematoma (RSH) in patients who have undergone video-assisted thoracoscopic surgery (VATS) has not been reported to date. This report describes a case of RSH patient with right abdominal muscle atrophy due an intercostal nerve injury following VATS. A 61-year-old male complained bulge the upper quadrant after undergoing Computed tomography (CT) revealed atrophied muscles, including...

The goal of this study was to quantify the relative contributions of each muscle group surrounding the spine to vertebral joint rotational stiffness (VJRS) during the push-up exercise. Upper-body kinematics, three-dimensional hand forces and lumbar spine postures, and 14 channels (bilaterally from rectus abdominis, external oblique, internal oblique, latissimus dorsi, thoracic erector spinae, l...
