In this episode the guys discuss two recent papers that build off of previous podcasts. The first article discussed is the use of BFR in Adolescents after ACLR. We previously chatted with the authors of this paper on our episode from June 23, 2020 titled "BFR in Kids!?!" The second paper discussed is a recent survey that was published looking into the use of BFR in persons with neurological conditions. We previously chatted with the primary author of this paper Mark Mañago, PT, DPT, PhD, NCS on November 18, 2020 Intro sound bite from: Trick or Treat (instrumental) by RYYZN https://soundcloud.com/ryyzn Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://bit.ly/l_trick-or-treat Music promoted by Audio Library https://youtu.be/uNPXJ9CDzbc
