The Immediate Effect of Mulligan's Mobilization With Movement on Shoulder Girdle' Pain, Range of Motion and Muscle Activity, in Subjects With Shoulder Impingement Syndrome

A randomized, single-blind, placebo-controlled clinical trial was conducted with a sample composed by twenty-four volunteers with SIS, divided in Mulligan's MWM and Placebo groups. Pain intensity in Neer impingement signal and Hawkins-Kennedy impingement test, pressure pain threshold (PPT) on the lateral aspect of shoulder, ROM of shoulder scaption until onset of pain, as well as the activity of trapezius (upper, middle and lower fibers) and serratus anterior muscles during this movement, were evaluated before and immediate (post-) intervention. The Mulligan's MWM group received a mobilization with movement technique in the glenohumeral joint (sustained posterolateral glide during shoulder scaption), while no effective intervention was performed in the Placebo group.
