Orthogonal Partial Least Squares model for Peak Speed for the neck pain group (n = 118) using self-rated characteristics as predictors. The Variable Influence on Projection (VIP), the lower limit of the confidence interval (CI) for the VIP and Pearson's correlation coefficients (r) are shown for the significant predictors, i.e., with VIP > 1 and a lower limit of VIP CI > 0.5. SF-36: short form-36; DASH: Disability of the Arm, Shoulder and Hand; NDI: Neck Disability Index. *p < 0.05, **p < 0.01.
