Manipulation Under Anesthesia (MUA) is truly an accurate name of the procedure. Those undergoing this are put under twilight anesthesia, or a mild sedative. While you’re in the drowsy and relaxed state two MUA specialists manipulate your spine and extremities. They are putting you through movements that – considering the present state of your problem – would hurt too much to perform without the sedative. Additionally, the anesthesiologist remains in the room for the entire procedure as well. The goal of MUA is to restore motion, break up adhesions that have formed in the muscles around the joint capsule and the nerve root.
