A table showing the time × group interaction for the change in pain and disability over the three sessions of the experiment. The F value and level of significance are displayed for the algometry (PPT), VAS and RM scores; baseline scores were used as a covariant.
ANCOVA, analysis of covariance; PPT, pressure-pain threshold; RM, repeated measures; VAS, Visual Analogue Scale.
