Dynamic stability co contractions with elastic band
Dynamic stability with co-contractions is a shoulder exercise where you perform small controlled movements against resistance from an elastic band while multiple muscles around the shoulder joint tighten simultaneously. This simultaneous tightening of muscles is called co-contraction and helps to keep the shoulder joint stable during movement.
The exercise mainly focuses on the cooperation between the rotator cuff and the muscles around the shoulder blade. Due to the unstable resistance of the elastic band, the body must continuously make small corrections to keep the arm stable.

When this exercise?
Dynamic stability with co-contractions is used to improve stability and control of the shoulder joint. The exercise is often used within shoulder rehabilitation when controlled activation of the rotator cuff and scapular muscles is important.
In addition, this exercise can be used preventively in athletes who perform a lot of overhead movements, to improve the stability of the shoulder joint. The light and easily controllable resistance of the elastic band makes the exercise suitable in different phases of training and recovery. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure that the exercise is safe and tailored to individual load capacity, symptoms and recovery status.
