Influence of trunk muscle co-contraction on spinal curvature during sitting cross-legged.
In Asia, many activities of daily living (ADL) are performed while sitting cross-legged on the floor. This sitting posture rotates the pelvis in a more dorsal direction and lumbar lordosis is more flattened than while sitting on a chair. Sitting cross-legged induces a greater load on the intervertebral discs and spine, especially when in a slumped position that is known to increase disc pressur...
متن کاملInfluence of trunk muscle co-contraction on spinal curvature during sitting.
BACKGROUND AND PURPOSE Slumped sitting is known to increase disc pressure and aggravate chronic low back pain. In addition, it has been recognized that co-contraction of the deep spine-stabilizing muscles enhances lumbar segmental stability and the sacro-iliac joint. The purpose of this study was to compare the electromyographic (EMG) activity of the trunk muscles and the muscle thickness of th...
متن کاملAssessment of Trunk Muscle Co-contraction during Multi-axial Movements
INTRODUCTION It has been well documented that individuals with chronic low back pain (CLBP) tend to exhibit different muscle activation patterns in the trunk musculature when compared with healthy individuals. Studies investigating the flexion relaxation phenomenon have observed the persistence of muscle activation during full trunk flexion in CLBP [1], while Silfies et al. [2] found that CLBP ...
متن کاملThe influence of trunk inclination on muscle activity during sitting on forward inclined seats.
The aim of the study was to estimate the influence of trunk inclination on muscle activity during sitting on forward inclined seats without backrest. The group consisting of thirteen healthy women was examined. Based on anthropometrical data two types of sitting position were adopted with two different angles between thighs and trunk: 120 and 135 degrees. Bioelectrical activity of five muscles ...
متن کاملEffects of handicraft sitting postures on lower trunk muscle fatigue.
The purpose of this study was to assess trunk muscle fatigue in seated handicraft tasks using surface electromyography (sEMG) and visual analogue scale (VAS) ratings for trunk discomfort, and to assess the relationship of these responses. Twenty-three participants were randomly assigned to assumed crossed-leg and heel sitting postures for 30 min. Normalised median frequency (NMF) slopes for lum...
