This is the first blog post in a continuing series on how to use BFR-rehab to attenuate muscle loss for a client with a recent combined ACL and meniscus tear which occurred doing a soccer match.
In the present post and the following, the focal point is how to add blood flow restriction (BFR) for ACL Reconstruction (ACL-R), so please consider that BFR is used in combination to the client-specific and standard care rehab exercises.
Currently, 4 weeks post op. the goal is reaching terminal knee extension asap and secondly, to attenuate muscle loss in the affected limb e.g. quadriceps, as joint effusion and swelling has almost abolished.
As the meniscus was repaired by sutures, limiting weight bearing activities and graduated exposure are imperative for the first weeks. Which is particularly important for his long-term knee mechanics, i.e., to evade knee OA.
In the video we got unloaded knee extension amplified by BFR, as the client is taxing to reach terminal knee extension.
For this client, the new direct connection Fit Manometer is a convenient alternative to the standard attach and detach solution and please notice this updated model is currently included in the Complete V3 versions. With this basic add-on, the pressure (mmHg) is swiftly monitored and adjusted accordingly by the rapid-deflate button or the screw-cock.
The sub-goal for this client is to succeed with the 30x15x15x15 rep protocol, then progressing the pressure to about 80% of Limb Occlusion Pressure (LOP), before using external load. Making sure no additional swelling or pain occurs compared to his conventional rehab exercises.
As a site note, knee flexion just progressed today and just barely enough to pedal on an exercise bike, so this will be implemented properly to his continued rehab.
More BFR applications will soon be implemented and likely also in conjunction with his recent and successful experience on an exercise bike.
Stay tuned to follow this rehab journey and hopefully a successful return-to-play within 2021.
