Hand and center of pressure (CoP) kinematics were compared between a control group and a frail group of the same age.Results: In frail individuals, the entire movement was impaired and slowed down. In addition, postural adjustments that classically precede and accompany the focal arm movement were delayed and reduced, especially in the CRT condition in which the motor prediction is more limited. Finally, a correlation between the time to CoP maximal velocity and the timed up-and-go score was observed.Conclusion: In these patients, it was concluded that the control of the CoP displacement evolved from a proactive mode in which the perturbation associated with the arm movement is anticipated toward a more reactive mode in which the perturbation is compensated by late and delayed adjustments.Keywords: frailty, anticipatory postural adjustments, backward disequilibriumKubicki ABonnetblanc FPetrement GBallay YMourey FDove Medical PressarticleFrailtyOlder adultsAnticipatory Postural AdjustmentsPostural controlBackward Disequilibrium.GeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 7, Pp 65-75 (2012)
