The initial effects of a Mulligan's mobilization with movement technique on range of movement and pressure pain threshold in pain-limited shoulders

There is little known about the specific manual therapy techniques used to treat painfully limited shoulders and their effects on range of movement (ROM) and pressure pain threshold (PPT). The objective of this study was to investigate the initial effects of a Mulligan's mobilization with movement (MWM) technique on shoulder ROM in the plane of the scapula and PPT in participants with anterior shoulder pain. A repeated measures, double-blind randomized-controlled trial with a crossover design was conducted with 24 subjects (11 males and 13 females). ROM and PPT were measured before and after the application of MWM, sham and control conditions. Significant and clinically meaningful improvements in both ROM (15.3%, F (2,46)=16.31 P=0.00) and PPT (20.2%, F(2,46)=3.44, P=0.04) occurred immediately after post treatment. The results indicate that this specific manual therapy treatment has an immediate positive effect on both ROM and pain in subjects with painful limitation of shoulder movement. Further study is needed to evaluate the duration of such effects and the mechanism by which this occurs.
