This is a quick video that looks at how you can use some unique training tools that focus on providing strength to weakened muscles like the serratus anterior via the use of vibration and oscillation! These tools are very useful in treating elbow injuries but can also be great in the rehabilitation of shoulder injuries.
In Vladimir Janda's book Assessment and Treatment of Muscle Imbalance he goes into great detail about the use of the flex bar and in his research he found that the activation of phasic muscles like serratus anterior was much higher than the tonic muscles like pec minor when oscillation training was used.
He noted that this technique may be very useful and have great potential for correcting muscle imbalance with people who had shoulder and scapula instability.
I myself have used these tools for a long time and many people used to think I was sucked into some crazy fitness craze, when in reality I had read a lot of research indicating the use of vibration tools can be a great way to improve strength in people with injury with minimal risk to joints.
The best part of these tools if you have never used them before is just how tiring they can be to your stabilizers and your core.
The exercises do not look difficult when you watch someone doing them but when you try it yourself you realize they are very hard.
While they are a great tool to use, on their own they will do little. You still need to learn how to move correctly and improve function of multiple areas as well. This just can be a nice tool to complement your other methods and exercises.
