Which tissue's neuromuscular integrity is addressed by strength testing?

• A. Contractile tissue
• B. Non-contractile tissue
• C. Bones
• D. Ligaments

Answer: (A)

Strength testing targets the muscle’s ability to generate force through contraction, which comes from the contractile tissue—the muscle fibers that actively shorten when activated. When you perform resisted movements, the patient must recruit motor units and activate the muscle fibers; a normal response reflects intact neural drive and healthy contractile tissue. Non-contractile tissues like tendons, ligaments, bones, or fascia don’t generate force themselves, though they contribute to force transmission or stability. So the neuromuscular integrity being assessed by strength testing is the contractile tissue.
