Stabilizers

Stabilizers: The role of a stabilizer is to improve arthrokinematics by maintaining optimal alignment of joint surfaces. Most often these muscles are the most intrinsic muscles of a joint, have a larger percentage of Type I muscle fibers, and are rich in proprioceptors. For example, the muscles of the rotator cuff act as stabilizers osteokinatic motions (e.g. flexion, abduction, etc.) of the shoulder.
