Journal ArticleDOI
Postural sway in low back pain: Effects of dual tasks.
Masood Mazaheri,Mahyar Salavati,Hossein Negahban,Mohammad Ali Sanjari,Mohammad Ali Sanjari,Mohamad Parnianpour,Mohamad Parnianpour +6 more
TL;DR: It is suggested that LBP may be one factor that modulates the posture-cognition interaction and is associated with higher determinism, higher entropy and lower trend in anteroposterior (AP) and mediolateral (ML) directions in people with LBP and healthy participants.
Journal ArticleDOI
Trunk coordination in healthy and chronic nonspecific low back pain subjects during repetitive flexion–extension tasks: Effects of movement asymmetry, velocity and load
Hamid Reza Mokhtarinia,Mohammad Ali Sanjari,Mahshid Chehrehrazi,Sedigheh Kahrizi,Mohamad Parnianpour +4 more
TL;DR: Coordination pattern and variability could be influenced by trunk flexion-extension conditions and was higher during asymmetric and low velocity conditions (p<0.001); however, there was less adaptation in the DP for the CNSLBP group, as shown by interactions of Group by Load.
Journal Article
Quantification and classification of low back disorders based on trunk motion
William S. Marras,Mohamad Parnianpour,Sue A. Ferguson,J.-Y.Y. Kim,Robert R. Crowell,Sheldon R. Simon +5 more
Journal ArticleDOI
Role of posture in mechanics of the lumbar spine in compression.
TL;DR: Biomechanics of the entire lumbar spine L1-S1 in erect postures was investigated under physiological axial compression loads of up to 800 N with and without right axial torques using a nonlinear finite-element model to generate stabilizing sagittal/lateral moments.
Journal ArticleDOI
Impairment magnification during dynamic trunk motions
TL;DR: Results indicate that motion measures can be used to help assess impairment magnification during functional trunk motion testing and can provide a means by which to scrutinize the quality of quantitative measures indicating the extent of a low back disorder.
