CASE STUDY: Part II – AC sprain during jiu jitsu
•••••••••••••••••••••••
In a previous post I discussed early management of a ligament sprain in the acromioclavicular joint (AC joint). The first phase was to protect the joint which entailed joint taping and using a sling to unload the joint. Next phase is optimal loading.
.
The primary impairment of an AC sprain is limited shoulder motion (and pain❗️) therefore the goal is to restore full range. Controlled articular rotations (CARs), a FRC concept (Functional range conditioning) is a method to explore the complete range of the isolated joint. Not only does this help maintain joint health but it can be used as a diagnostic tool to detect limitations and pain. Complete a full PAIN-FREE circle with 20% muscle contraction (video was 2x as fast as actual CAR).

The acromioclavicular joint’s job is to work in conjunction with the sternoclavicular joint to assist the scapula with upperward rotation. This is what allows the shoulder to reach overhead. This makes scapulothoracic CARs key for early rehab of the AC joint. Once the painful ranges are detected isometric holds can be used to properly load the joint to allow for adequate tissue healing.
