- SFS scores and improvement of the SFS score from before measurement are presented as mean with 95% confidence intervals. Spearman’s r describes the correlation of SFS scores before and after performance of the FCE and is presented with 95% confidence intervals based on bootstrap analysis based on 10.000 replicas. Superscripts indicate hypothesis tests with α = 20% to support similar results. aKruskal-Wallis H tests, bpairwise tests for correlations, SFS Spinal Function Sort, FCE functional capacity evaluation
