BACKGROUND AND PURPOSE Normative age-related decline in paravertebral muscle quality is important for reference to disease and risk identification in patients. We aimed to establish age- and vertebral level-dependence of paravertebral (multifidus and erector spinae) muscle volume and fat content in healthy adult volunteers. MATERIALS AND METHODS In this prospective study multifidus and erecto...

BACKGROUND The prone leg extension (PLE) is a clinical test used to evaluate the function of the lumbopelvis. It has been theorized that a normal and consistent pattern of muscle activation exists. Previous research has found two contradictory patterns of muscle activation during PLE in normal individuals. One study shows an almost simultaneous activation of the lower erector spinae and hamstri...

The effects of pelvic asymmetry and idiopathic scoliosis on postural balance during sitting were studied by measuring inclination angles, pressure distribution, and electromyography. Participants were classified into a control group, pelvic asymmetry group, scoliosis group, and scoliosis with pelvic asymmetry and then performed anterior, posterior, left, and right pelvic tilting while sitting o...

Professional cyclists often adopt a competition-start standing posture, which has been shown to improve performance. The biomechanical basis of this is unclear, and might be due to a greater mechanical advantage or increased key muscle activity. Previous observations in steady state cycling showed greater activation of the tibialis anterior, erector spinae, and biceps brachii when adopting a st...

The aim of the present study was to investigate the relation between self-reported pain, muscular activity and postural load during cleaning tasks. Eighteen cleaners performed usual cleaning tasks in both a laboratory and a lecture room. The level of perceived pain in the neck-shoulder region during the last 7 days was recorded. Bipolar surface electromyography (SEMG) was recorded bilaterally f...

Background: Erector Spinae Plane Block (ESPB) belongs to the family of fascial plane blocks in which local anesthetic is injected into a between two layers fascia and subsequently spreads nerves located within that or adjacent tissue compartments. ESPB has been used pain management, cervical, thoracic cardiovascular surgeries. Objective: The goal this narrative review article go through pertin...

[Purpose] The purpose of this study was to investigate the effect of anterior pelvic tilt taping (APTT) on the anterior inclination of the pelvis when Kinesio tape (KT) was applied to the erector spinae and the internal oblique, which are involved in anterior pelvic tilt. [Subjects] Forty asymptomatic adults (twenty-three males and seventeen females) agreed to participate in this experiment. [M...

Objective To assess the cross-sectional area (CSA) of the muscles for investigating the occurrence of asymmetry of the paraspinal (multifidus and erector spinae) and psoas muscles and its relation to the chronicity of unilateral lumbar radiculopathy using magnetic resonance imaging (MRI). Methods This retrospective study was conducted between January 2012 to December 2014. Sixty one patients ...

[Purpose] This study examined the correlation between the muscle activities and joint angle of the hip and knee according to the changes in stance width during a lifting task. [Subjects and Methods] The subjects of this study were 15 healthy students. A three-dimensional motion analyzer (SMART-E, BTS, Italy) was used to measure the joint angles of hip and knee during lifting. An 8-channel elect...
