Immediate Effect of Cryo-Ischemic Compression on Pain and Range of Motion in Frozen Shoulder with Active Middle Deltoid Trigger Points: A Single-Arm Pilot Study

Background: Active myofascial trigger points (MTrPs) in the shoulder girdle may add to pain and movement restriction in frozen shoulder. Cryo-ischemic compression (CIC) combines sustained manual pressure on an MTrP with simultaneous cold application. This pilot study examined the immediate effect of a single CIC session on pain and shoulder range of motion (ROM) in patients with frozen shoulder and an active middle deltoid MTrP.
