Kinematic analysis of symmetric axial trunk rotation on dominant hip.
Axial rotation of the trunk has been reported as a significant risk of low back dysfunction. However, a lack of biomechanical investigation exists that explains how twisting is accomplished with simultaneous asymmetric handling between the hip joints and lumbar spine. We used a three-dimensional motion analysis to measure movements of the bilateral hips and lumbar spine. Forty-four persons part...
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 کاملAngular Velocity Affects Trunk Muscle Strength and EMG Activation during Isokinetic Axial Rotation
OBJECTIVE To evaluate trunk muscle strength and EMG activation during isokinetic axial rotation at different angular velocities. METHOD Twenty-four healthy young men performed isokinetic axial rotation in right and left directions at 30, 60, and 120 degrees per second angular velocity. Simultaneously, surface EMG was recorded on external oblique (EO), internal oblique (IO), and latissimus dor...
متن کاملInter- and intraobserver reliability assessment of the axial trunk rotation: manual versus smartphone-aided measurement tools
BACKGROUND Scoliogauge, has been developed for the measurement of ATR on iPhone smartphones. This study was to evaluate the reliability for the smartphone-aided ATR measurement method and to compare its reliability with that of the manual method. METHODS Sixty-four AIS patients with single thoracic or lumbar curve participated in this study. Of these patients, thirty-two patients had main tho...
متن کاملImproving trunk rotation.
Figure 1 Kneeling trunk rotation (a) start position (b) final position. Sports such as tennis, golf, baseball, and hockey each involve a tremendous amount of trunk rotation. It is not just striking sports, but also throwing, kicking, running, swimming, skiing, etcwhichall require yourbody to rotate throughyour core. In order to transmit forces from your bigger, stronger leg muscles to your arms...
