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.

| Myofascial release therapy | Other | Crossed hands technique. This approach is based on stimulating the myofascial system through the application of slow and gradual pressures. Its objective is to restore hydration and release deep restrictions within the soft tissue that cannot be reached with direct pressure or are difficult to identify during the initial evaluation process |
| Measure | Description | Time Frame |
|---|---|---|
| Pelvic mobility | 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 | This variable will be measured before the intervention and inmediatly after the intervention, all in the same day. |
| Fascial stiffness | 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. | This variable will be measured before the intervention and inmediatly after the intervention, all in the same day. |
| pressure pain threshold (PPT) | Pressure Pain Threshold (PPT) is defined as the minimum amount of pressure applied to a tissue that is perceived as painful by an individual. | This variable will be measured before the intervention and inmediatly after the intervention, all in the same day. |
