The MWM technique involved the manual application of a sustained joint glide in which the talus was mobilized posteriorly in the ankle mortise and resulted in immediate improvements in posterior talar glide and dorsiflexion. It is feasible to postulate that the increase in posterior talar glide and dorsiflexion seen in this study following the MWM may be related to a reduction in positional fault at the talocrural joint. Alternatively,it is equally plausible that no positional fault exists in the presence of a reduced posterior talar glide test but, rather, there is purely a limitation of joint motion: the MWM may have produced its effects through improving (accessory) joint mation, not a change in talar position.
