Leg Length Discrepancies, Voodoo Bands, and FAI – Movement Debrief Episode 48

Movement Debrief Episode 48 is in the books. Below is a copy of the video for your viewing pleasure, and audio if you can’t stand looking at me.

Here is the set list:

  • What is the long-sit test?
  • Can we accurately measure leg length discrepancies?
  • How relevant are leg length discrepancies?
  • What’s the deal with voodoo floss/compression bands?
  • Are they effective?
  • How is femoral-acetabular impingement treated?
  • What considerations need to be made with a cam vs. pincer impingement?

If you want to watch these live, add me on Facebook or Instagram.They air every Wednesday at 7pm CST.


ERROR: I misspoke on the different impingement types. A Cam impingement is a change in the femur, whereas a pincer impingement is a change on the acetabulum
