简要总结
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.

Introduction
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. Objective: 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. Methods: A quasi-experimental study was conducted with 30 healthy participants, divided into three groups (n = 10 each). Each received a single 5-minute session of the crossed-hands technique on the thoracolumbar fascia using forces of 2 kg (G3), 5 kg (G2), or 11 kg (G1). Fascial stiffness was measured with a Shore 00 durometer, thickness via ultrasound (Mindray TE7), pain pressure threshold (PPT) by algometry, and lumbopelvic mobility using Kinovea® motion analysis.

结局指标
主要结局
Pelvic mobility
时间窗: This variable will be measured before the intervention and inmediatly after the intervention, all in the same day.
Subjects will be placed in a standing position and instructed to touch the floor with their hands while keeping their knees extended. The variables analyzed are anterior pelvic tilt and the translation angle of the lower limbs
Fascial stiffness
时间窗: This variable will be measured before the intervention and inmediatly after the intervention, all in the same day.
Fascial stiffness is the mechanical property of fascial tissue that reflects its resistance to changes in shape or length when subjected to an external force. It is influenced by the composition and organization of the extracellular matrix, collagen fiber arrangement, tissue hydration, and neuromuscular factors.
pressure pain threshold (PPT)
时间窗: This variable will be measured before the intervention and inmediatly after the intervention, all in the same day.
Pressure Pain Threshold (PPT) is defined as the minimum amount of pressure applied to a tissue that is perceived as painful by an individual.
