Biomechanical properties of muscles, joints, and soft tissue affected or altered due to weakness or spasticity are part of which muscle-tone component?

• A. Soft tissue/Structural Component
• B. Neural Component
• C. Muscle Component
• D. Skeletal Component

Answer: (A)

The key idea is that this question is about the passive, non-neural properties of the body—the actual physical tissues that determine how stiff or stretchy muscles, joints, and surrounding soft tissues are. When weakness or spasticity occurs, connective tissue, muscle-tendon units, joint capsules, ligaments, and other soft tissues can become stiffer, less extensible, or shortened. These structural changes change how the limb resists movement and stretch, independent of neural signals. That’s why they’re categorized as the soft tissue/structural component. The neural component would involve control signals and reflexes, while the muscle component refers to the active contractile properties of the muscle itself, and the skeletal component to bones.
