Clinical parameters are current neck pain measured by NRS, neck disability index (NDI), duration of current neck pain episode, and kinesiophobia measured by TSK. Given values are Pearson’s r for NRS, NDI and TSK and Spearman’s rho for duration with corresponding p-values. Correlation coefficients with p < 0.05 are in bold.
1 Duration of pain, five categories from short to long duration of current neck pain.
2 Fly test with easy pattern and small neck range of motion.
* = p value < 0.05. ** = p value < 0.01.
NRS = numerical rating scale. NDI = Neck Disability Index. TSK = Tampa Scale of Kinesiophobia. INF = isometric neck flexion. PD = point deviation. FOE = figure-of-eight. EOB = eyes open balance pad.
