Visual analogue scale for the perceived influence of exertion and movements/positions on low back problems in surveys of adolescents.
The test-retest reproducibility of visual analogue scales for the perceived influence of exertion and movements/positions on low back problems in adolescents was investigated. The study was performed on 61 adolescents with low back problems. Item completion, median score, interquartile range and weighted kappa were calculated. Results showed that visual analogue scales produce repeatable information for all items tested (weighted kappa: 0.59-0.83), except for the influence of pulling materials on back problems (0.45).


CONCLUSIONS
The results of this study suggest that adolescents, aged 16-18 y, can reproduce their visual analogue scores.
