Joint Mobilization Techniques Are Thought to Be Safer Than Passive

question 14

Multiple Choice

Joint mobilization techniques are thought to be safer than passive angular stretching using physiological ROM to increase mobility of capsular and ligamentous structures because:

• A)A therapist has a better mechanical advantage (leverage) over the tight structures when using mobilization techniques.
• B)Mobilization techniques replicate the less traumatic rolling motion of the bone surfaces.
• C)Mobilization techniques direct forces specific to the involved capsular and ligamentous tissues without causing compressive damage to the articular cartilage.
• D)Mobilization techniques are applied only in the resting positions of joints, not end-range positions.

Lewis Structure

A Lewis structure is a diagrammatic representation of the arrangement of valence electrons around atoms in molecules, indicating the bonding between atoms as well as the lone pairs of electrons.

Ethyne

A colorless gas with a sharp, distinct odor; the simplest alkyne, it is a hydrocarbon with the formula C2H2.

Acetylene

A hydrocarbon and the simplest alkyne, used as a fuel and a chemical building block, recognized by its formula C2H2.

Covalently Bonded Molecule

A molecule whose atoms are held together by covalent bonds, which involve the sharing of electron pairs between atoms.
