An objective of NDT therapy is to increase reciprocal muscle function for what?

• A. Isolated distal movement
• B. Righting and equilibrium reactions
• C. Purely reflexive responses
• D. Maximum voluntary contraction of non-salient muscles

Answer: (B)

The idea being tested is how NDT therapy aims to restore coordinated, reciprocal muscle function to support posture and balance. Reciprocal muscle function means muscles work together in coordinated pairs or groups so movement and postural adjustments are smooth and integrated, not isolated or reflex-driven.

Righting and equilibrium reactions are automatic postural responses that keep the body's orientation and balance when the body is moved or perturbed. Improving how muscle groups coordinate helps these reactions be more effective, enabling better head, trunk, and limb alignment during movement and in varied positions. This is why strengthening reciprocal muscle function best supports righting and equilibrium responses.

Isolated distal movement focuses on a small, specific part without addressing overall coordination needed for posture. Purely reflexive responses rely on automatic reflexes rather than purposeful, coordinated action. Maximum voluntary contraction of non-salient muscles ignores the need for balanced, cross-muscle coordination that underpins posture and stability.

So the option targeting righting and equilibrium reactions best reflects the goal of enhancing reciprocal muscle function.
