This paper presents general results concerning the quantum dynamics in a tilted, time-modulated, one-dimensional, optical lattice. A dynamic equation describing the atomic motion is analytically solved, and the solution used to characterize the corresponding dynamics through the spatial mean position and dispersion of the wavepacket. The analysis of such quantities gives a quite complete picture of the quantum dynamics, and provides evidence for the central role of the quantum coherence.
