What are we listening to this week

Therapy Insiders interview with Stu McGill entitled “the mechanics of a treatment approach with Dr. Stuart McGill"This was an interesting interview with some nice clinical pearls. Anyone who has had the opportunity to see Dr. McGill speak will certainly appreciate his humor and candor.

After a lengthy discussion on mustaches, they began to talk about competency of therapists. Dr. McGill then explains some salient points in his three hour evaluation of patients. His goals are to "precisely define The pain triggers to that patient” and then to “remove them”. Pretty simple but effective. We think the keyword here is “precisely”.He then talks about utilizing your clinical knowledge based in the powers of observation. 

His assessment begins with a patient interview to determine The character of the patients pain. He’s very careful to listen to “exactly” what the triggers and really are for a patient’s pain. He then goes on to offer some nice clinical diagnostics pearls that we will leave for you to listen to the podcast to glean.

He then again emphasizes observing the patients movement and movement habits to establish their stability/mobility continuum. His examination consists of three parts: provocative motions, neural tests, and tissue specific tests. He looks for provocative motions postures and loads.  Once the pain should use identified, he then seeks to find positions postures or movements which will alleviate it. He then does neural tests, looking for things like neural or root tension. Finally he discusses some tissue specific diagnoses.

There’s an interesting discussion on pain and pain science. Dr. McGill emphasizes that people need to avoid the movement which causes pain not moving in general. He then goes on to talk about Central sensitization and how, if you can teach people to not invoke their “pain trigger” motion, that they will actually improve and central sensitization will decrease. in other words, don’t move “through” pain but find ways to work around the trigger.

There’s been a series of “Twitter” questions that are answered with an interesting discussion on Core stability and superimposed axial movement. All in all a informative interview with some clinical pearls.

modified Delphi study, 42 experts from 11 countries

http://www.jfootankleres.com/content/supplementary/s13047-015-0094-5-s1.pdf

-Results

The following definition of minimalist shoes was agreed upon by 95 % of participants: “Footwear providing minimal interference with the natural movement of the foot due to its high flexibility, low heel to toe drop, weight and stack height, and the absence of motion control and stability devices”. Characteristics to be included in MI were weight, flexibility, heel to toe drop, stack height and motion control/stability devices, each subscale carrying equal weighing (20 %) on final score.

From a Reader:

Dear Gait Guys, Dr. Shawn and Dr. Ivo,  I was referred to this post of yours on hip IR…http://thegaitguys.tumblr.com/post/14262793786/gait-problem-the-solitary-externally-rotated   I am impressed by the level of details of your understanding of the gait and biomechanics. Although I am still trying to understand all of your points in this post, I would like to ask you:  What if my IR is limited due to a structural issue? The acetabular retroversion of the right hip in my case. 

I.e. if I am structurally unable to rotate the hip internally.
What will happen? 
What would be a solution to the problem in that case?

Hey Gait Guys,

I understand that 1st MP Joint dorsiflexion, ankle rocker, and hip extension are 3 key factors for moving in the sagittal plane from your blog and podcasts so far. I really love how you guys drill in our heads to increase anterior strength to increase posterior length to further ankle rocker. I’ve seen the shuffle gait and was curious if you had a good hip extension exercise to really activate the posterior hip extensors and increase anterior length.

 am posting this to see if I can get a little bit of help from the best professionals in the area (you). 

I have read some of the information on your site and I think I have quite a problem on my right foot. It happens that the medial part of the foot tripod does not touches the floor at all and I have lack of support in that zone. So it seems like my forefoot is varus. I have also noticed that when I am standing it looks like my rear foot is valgus. So, I can’t really compensate this problem because if the forefoot is varus and I try to put it neutral, the rear foot gets even more valgus, and if it I try to put the rear foot neutral, the forefoot gets even more varus and my big toe does not touch any part of the floor. Can you please help me? I do not know what to do and I am a little bit desperate because nobody I went to could help me. You are probably my last hope. I know I can correct this and I have the will and dedication to pull it off. I bet there are some exercises I can do but I do not really know which at all. 
Thanks in advance. -Jorge

4- FB reader sent us a message:
Hi Gait Guys,

I have anterior pelvic tilt and overpronation of the right foot.

at gait, LEFT foot does toe off properly and straight.
However, RIGHT foot moves towards my center at toe off. It just sort of caves in & moves in as well.

I managed to really reduce that(i think) from massages and strengthening glutes etc but I would just like to know what causes that so I know what to target.

Once again, congratulations on your work. Not only has it not been done before over the whole internet it is excellent.

6- Questions from a field doc:
Hey guys,

I have a couple questions for you that you could possibly use or you could simply answer them via email. 
1)  Ivo, in one of your videos on muscle function you talk about muscle inhibition.  I always thought the CNS simply chooses not to recruit all of the motor units in a muscle or chain of muscles to protect from injury, compensate, etc.  You mentioned in your video the CNS somehow recognizes the spindles in these motor units are already “turned on” so they will not activate.  I’m not sure I have this correct but I was hoping you could elaborate on this confusing but interesting neurological phenomenon.
7- Patient case yesterday:
Runner comes in and says “i keep landing on the outside of my left foot when i run, it is there a little when i walk, but more prominent when i run. Everywhere i read the armchair experts are saying to just let foot strike happen naturally.  Do i leave this alone ? Oh, and my left hip is always tight.”

5- EMAIL Question:
Hi! 

I saw your blog and one of your youtube videos and thought I would mail in a gait question! I appreciate any input or information you have about this. I was wondering about people that walk with their foot in the abducted position – why is this and what are the implications for such a gait? I know some people with flat feet have that tendency but I don’t have that and walk at baseline with my foot abducted. I took note of this since I’ve developed some hip pain recently and noticed that when I make a conscious effort to walk with my feet straight it actually feels abnormal (more comfortable and natural with the feet abducted). Why is this? Any input into this puzzle would be appreciated. 
Thanks much!  -Sheeva
