Whilst dark matter remains the consensus model for solving many issues in gravitational physics and cosmology, so long as there remains no direct experimental detection, it is prudent to consider alternatives. Theories of modified gravity, which seek to explain the galactic missing mass problem and Tully-Fisher relation without the 'dark sector', are one such alternative. Whilst ostensibly testing such theories should fall into the same category as those of dark matter searches, I will outline a direct test of departures from GR, for theories with a preferred acceleration scale, which could form part of a extension for the forthcoming LISA pathfinder mission, as well as explore the parameter space of such theories and how they may be constrained from experiment.
