The Relationship between Transversus Abdominis and Postural Alignment of Lumbopelvic - Hip Complex in Relaxed Standing Position of Female Students of Christian University of Thailand
Abstract
The objectives of this study were to explore the relationship between the pelvic inclination, lumbar lordosis and hip angle during relaxed standing through to contribute to the power of Transversus Abdominis in 94 female students aged 18 - 25 years old who have normal muscle power of Rectus Abdominis, External Abdominal Oblique and Internal Abdominal Oblique and normal muscle length of Psoas muscle. All subjects were examined a muscle power of Transversus Abdominis by Zonnotti's method, depth of lumbar curve by Lovell's method, pelvic inclination by Sander's method, and hip angle in relaxed standing position.
The findings of this study found that there were a high negative correlation between muscle power of Transversus Abdominis and pelvic inclination (p < 0.0001) (r = -0.834), a high negative correlation between muscle power of Transversus Abdominis and lumbar lordosis. (p < 0.001) (r = -0.899), a little positive correlation between hip angle and pelvic inclination (p < 0.05) (r = 0.206), a very high positive correlation between pelvic inclination and lumbar lordosis (p < 0.001) (r = 0.936). In conclusions, the weakness of Transversus Abdominis increases the depth of lumbar curve and pelvic anterior inclination. Therefore, the use of strengthening exercise for Transversus Abdominis should be considered to correct Lumbo-pelvic-hip faulty standing alignment.
