What is it about?
This study investigated anticipatory postural adjustments (APAs)and compensatory postural adjustments (CPAs) and their relation ship in older adults during lateral postural perturbations.

Why is it important?
Anticipatory and compensato ry adjustments represent the Central Nervous System’s (CNSs)ability to respond to postural disturbances, preventing loss of equilibrium and falls. Lateral instability is astrong predictor of falls in older individuals; however, data on the modulation of these adjustments, and their relation ship, in muscles that provide lateral postural stabil ity is scarce. Older adults used higher compensatory activity and similar anticipatory adjustm ents during lateral perturbations when compared to young individuals. Neverth eless, they showed greater postural instability after the postural disturbances.
Perspectives
These findingsprovide new data on the role of APAs and CPAs in their relationship in older adults during external lateral perturbations and may advance current rehabilitative management strate- gies to improve balan ce control in older individuals.
