Kongen- I try this technique a lot with pts presenting with passive restriction internal rotation, at 90 hip flx... I find it to work really well, but if (like all mulligan techniques) if there is no carry-over the next few sessions usually abandon the technique. I do it passive, far hand inside the belt and sustaining lateral glide, usually reps up to 3x10 mobs. opens up PROM well, as far as AROM you could have them moving with you on an extra set post mobs while still doing the glide... you can also help AROM by maintaining the same lateral glide while they are standing doing a step up/squat/whatever they have pain with (not specific to the int. rot you mentioned, but if they have pain with something functional, then no pain with the glide, have them do 3 sets 10 maintaing the glide and retest without... the guidelines are must be relatively painfree, and have carry over). Theres a new text called Mobilisation with Movement; the Art and Science, that has mostly case studies and theory/background on positional faults... dont have it with me but Ill check on specifics
While performing manual therapy techniques, there are contraindications to treatment and should be respected at all times. This treatment is always guided by the rule of never causing pain. But while using this therapy in the extremities we should strictly abide by the basic rules of application of manual therapy techniques. Before performing this treatment procedure, it is important to identify the signs of loss of joint movement, pain associated with movement, or pain associated with specific functional activities.
