The tendons in your fingers are anchored down by pulleys that keep the tendons gliding flush to the bones. Excessive strain on the finger can exerts an outward force on the pulley which may strain or tear it.
The shoulder is made up of four rotator cuff muscles. These muscles act together as a unit to control shoulder motion. Often times there is an imbalance in the strength of the rotator cuff muscles. The external rotator muscles are commonly weaker than the internal rotator muscles. This imbalance over time can lead to a strain of the rotator cuff.
The shoulder is made up of four rotator cuff muscles. These muscles connect the shoulder blade to the arm bone. The rotator cuff muscles act together as a unit to control shoulder motion. You need to strengthen the rotator cuff to prevent muscle strain.
