Which is an indication of an anterior tilt in the pelvis?

An anterior tilt in the pelvis is characterized by a forward rotation of the pelvis, which typically results in an arched lower back. This arching occurs because the lumbar spine curves excessively as the pelvis tilts forward. When the pelvis is in an anterior tilt position, the hip flexors, particularly the quadriceps, may also become tight due to the increased demand they experience in that alignment.

This relationship is crucial as it links the position of the pelvis with muscular tension. Tight quadriceps can contribute to this tilt, and the combined effect can lead to postural issues and discomfort. Therefore, identifying an arched lower back along with tight quadriceps provides a clear indication of anterior pelvic tilt.

In contrast, options that suggest a flat lower back, loosely aligned spine, or a neutral pelvis position do not align with the characteristics observed in anterior pelvic tilt. A flat lower back would typically indicate a different pelvic alignment, while a loosely aligned spine and neutral pelvis suggest a balanced and stable positioning rather than an exaggerated arch from anterior tilt.
