This simply means to brush synthetic turf in the opposite direction to its turf lean. Defibrillation can be done manually with a rake and/or push broom or mechanically with a motorized sweeper.

Turf defibrillation will get your turf piles standing toward the vertical position. Also, it will untangle any piles that are intertwined or braided. Finally, defibrillation will separate any ‘conjoined’ turf piles. (picture with pointers forthcoming)
