Effect of Three Force Magnitudes During the Cross-Hand Technique in the Thoracolumbar Region on the Myofascial System in Healthy Adults

Orthopedic Manual Therapy (OMT) employs specific manual techniques to assess and treat musculoskeletal dysfunctions. Among these, the Myofascial Induction Method (MIM) and its "crossed hands" technique are designed to restore fascial mobility and hydration through sustained mechanical forces. However, the lack of standardization (particularly regarding applied force) limits reproducibility and clinical consistency. The objective of this research is to compare the effects of three force magnitudes (2 kg, 5 kg, and 11 kg) applied during the crossed-hands technique on fascial stiffness, thickness, pain pressure threshold, and lumbopelvic mobility in healthy adults.
