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.

7.  Bunions
 I am a fitness instructor, and teach mostly barefoot classes…Pilates, yoga, willPower & grace. One of my students came to me originally because she has had bunion surgery, and wanted to regain alignment and strength in her feet. She is doing well with her big toe, but due to compensations made for the bunion, she has this pronounced  protrusion of the lateral edge of the foot by her 5th toe and metatarsal.  It looks larger in person than it does in the photo and is painful for her.  What is the cause and are there specific exercises for her?
Thanks for any insight,
Suzy

Effect of customized foot orthotics in addition to usual care for the management of chronic low back pain following work-related low back injury.

The findings showed that patients in this study with chronic, nonspecific low back pain following work-related low back injury had greater improvement in short-term outcomes with orthotics and UC than with UC alone.
