Data are reported as mean (SD)

CST, chair stand test, number of stand ups; SHR, standing reach height, numbers represent centimetres; ODI, Oswestry disability index, scoring from 0 to 100, 0 = no pain; VAS, visual analogue scale, scoring from 0 to 10, 0 = “no problems” and 10 = “maximum problems”; Time before prime mover, negative numbers represent time (s) before prime mover, positive represent time (s) after prime mover; P₁-value, difference between the baseline’s and 3 months’ mean; P₂ value, difference between the 3 months’ and 18 months’ mean; P₃ value, difference between the baseline’s and 18 months’ mean; ANOVA, one-way repeated-measure ANOVA; ANOVA _1,2 difference between the baseline’s and 3 months’ mean; ANOVA _2,3 difference between the 3 months’ and 18 months’ mean; ANOVA _1,3 difference between the baseline’s and 18 months’ mean
