In this study, we found functional relations between the eye and body movements in a search task because healthy young individuals exhibited only negative Pearson correlations between the eye and body (i.e., head and neck

Unfortunately, most validated biopsychosocial questionnaires have been developed for patients with LBP and not in

The resulting CoP

sample with the Brief Resilience Scale, a short-measure scale validated (α = .80–.91) among several samples. The 6-item scale measured resiliency using a 6-point Likert scale ( 1 = strongly disagree; 6 = strongly agree ) and questions 1, 3, and 5 were positively worded. Questions were centered on the

Finally, no experimental muscle activations (electromyography) were available to further validate the static optimization results, which is a limitation of this study. Modeling assumptions affect the

Modeling System has been used for injury prevention studies, measuring joint reactions in, for example, lifting, 14 , 15 wheelchair propulsion, 16 and volleyball. 17 Validation studies of simulated compression forces between vertebrae L4 and L5 show good agreement with measured reactions. 15 , 18
