Key result
A 4-week home-based blood flow restriction exercise program increased knee extensor strength by 20±14% (P<0.01) and restored strength symmetry to levels of uninjured controls.
Why the study?
Quadriceps atrophy and weakness can persist for years after anterior cruciate ligament reconstruction (ACLR).
Does a home-based blood flow restriction exercise program improve quadriceps size and strength in adults long after anterior cruciate ligament reconstruction?
Population

Home-based BFR may aid late quadriceps recovery after ACLR; case-control data leave open efficacy in randomized trials.
Does a home-based blood flow restriction exercise program improve quadriceps size and strength in adults long after anterior cruciate ligament reconstruction?
p-value: p=<0.01
A home-based blood flow restriction exercise program is safe, feasible, and effective at improving quadriceps size and strength several years after ACL reconstruction.
Kilgas et al. (2019) studied Anterior cruciate ligament reconstruction (ACLR) (n=18). Home-based blood flow restriction (BFR) exercise program vs. Uninjured controls / Baseline was evaluated on Rectus femoris and vastus lateralis thickness and knee extensor strength (p=<0.01). A 4-week home-based blood flow restriction exercise program increased knee extensor strength by 20±14% (P<0.01) and restored strength symmetry to levels of uninjured controls.
