Mean differences among conditions in the (A) maximum vertical force under the feet, (B) movement time, (C) maximum angle of hip extension, and (D) the time of maximum hip extension as a percentage of the total movement time. The thin gray lines represent average values for each participant, and the thick black line represents the group mean. All of the illustrated variables exhibited significant (P < 0.05) changes in the Pain condition relative to one or both of the NoPain conditions. Notice the variability in the participants’ absolute values and in the extent of the condition-related changes in behavior.
