Cross friction is described as being done mainly on which structures?

• A. Musculotendinous structures; biomechanical changing of connective tissue; primary effect is on the non-vascular tissues
• B. Nerves
• C. Skin surfaces
• D. Bones

Answer: (D)

Cross friction massage targets dense connective tissues, especially musculotendinous structures like tendons and ligaments, where scar tissue and adhesions can limit movement after injury. The technique uses deep, transverse strokes across the tissue fibers to mechanically disrupt disorganized scar tissue and encourage realignment of collagen fibers along the normal lines of tension. This microtrauma stimulates local fibroblast activity, increases local blood flow, and promotes remodeling, helping the tissue glide more freely and reducing pain with movement. These tissues are the focus because they have a fibrous, collagen-rich matrix that benefits from this targeted mobilization. In contrast, applying friction to nerves, skin surfaces, or bones is not typical practice and can cause irritation or injury, so those structures are not the primary targets of cross friction.
