Which pelvic tilt is commonly associated with hypotonia?

• A. Anterior Pelvic Tilt
• B. Lateral Pelvic Tilt
• C. Neutral Pelvis
• D. Posterior Pelvic Tilt

Answer: (D)

Hypotonia often shows up as a pelvis that sits in a posterior tilt because the core and hip-stabilizing muscles are underactive. When the abdominal muscles and hip flexors aren’t providing enough tone, gravity and the remaining posterior structures pull the pelvis backward. This backwards tilt also reduces the normal curve in the lower back, contributing to a more slumped posture that’s commonly seen with low muscle tone.

In contrast, anterior pelvic tilt comes from tight or overactive hip flexors and lumbar extensors, a pattern more typical of higher tone or spastic tendencies. A neutral pelvis indicates balanced tone and control, while a lateral tilt signals unilateral weakness or asymmetry rather than a generalized low tone. So the posterior tilt is the tilt most commonly linked with hypotonia.
