Brief Research Note
When researchers are designing massage protocols, most often what is used is general techniques applied to non-specific areas delivered in a resting, or neutral position.
From what I have come across, is that research that uses a dynamic approaching to soft tissue treatments (passively or actively moving the limb through a wide range of motion), often show more positive effects.
