Sorry to be so absent. I have been extremely busy in the office, and working on a neck treatment book. It should come out in 2011.
I will throw in a few cents on this topic.
Being a DC, I learned to measure limb length with the patient…"
"Hey guys . . interesting post on a critically important topic. Walt, as usual, is in my view right on the money. A few more things to consider; how is it all put back together i.e. misalignments, fascial migration around the pelvis, issues with…"
"Thanks Walt, this is great information! I am trying to differentiate forefoot external rotation (abduction) from tibial external rotation because I just took an orthotic seminar that makes a distinction betwwen the two in their algorithm. If the…"
"I would back up to the hips first. Get them prone and measure internal vs external rotation. Int Rot should be 35 degrees, external 45 degrees. Limitations in one direction or another will give you an indication as to whether the hips has tightness…"
"Thanks, Walt. Here's another question: How do you measure tibial rotation versus forefoot abduction/adduction. That is, if you see externally rotated feet how do you know if it is coming from the forefoot versus coming from tibial external…"
"Legs in midline" just refers to assuring that the leg, when measured in supine, are in a neutral alignment and not shift off to one side.
Rotation is checks by palpating and comparing each ASIS and PSIS. Low ASIS indicates…"
"I don't mean to butt in before Joe, but I use a supine measurement. With legs in midline, I traction then rest the legs on the table. Thumbs nestled under each medial malleoli and compare sides. Chiros often do this in prone, but I find it…"
"Also remember kinetic chain biomechanics when treating the psoas. This means we have to treat the posterior calf complex of both legs and the opposite side psoas. Consider gait. What (from a chain reaction biomechanics point of view) will cause the…"
"The direction of Roll is always in the same direction that the bone is moving and the contact point between the bones moves in the same dirction as the Roll. The direction of glide however depends on whether that bone is convex or concave.
What direction is the Roll of the articular surface in relationship to the direction that the bone is moving (taking the case of one bone moving on a stationary bone)?
Does the direction of the Glide depend upon whether the bone end is…"
