I would nearly call the Maneuver a costum move by Little One right now.
Disabling Strike is a 5th Level Maneuver of the Diamond Mind school of martial maneuvers. Additional to dealing normal damage, the target is also forced to make a Will save, if the target fails the will save it's entire body become disabled and is not allowed any actions (though attacks of opportunity are still okay) for one round.
Little One likes to use that maneuver against Constructs because they are actually vulnerable against that maneuver, because it's not a daze or a stun (which most construcs are immune too) but just a straight you lose your actions ability.
Little One may have renamed Disrupting blow (because that's the effects of the maneuver in my book) to Disabling Strike.
