An adaptation to repeated trip perturbations in subjects with a history of whiplash-associated dysfunction.

Individuals with a history of whiplash-associated dysfunction (WAD) possess sensorimotor disturbances and a disruption in dynamic standing balance. However, trunk sway reactions have not been carefully investigated between a WAD group and control subjects. The results of this study indicated that the WAD group demonstrated delayed reaction times at first perturbation, and there was a significant interaction between trunk velocity and repeated trip perturbations.
