Standing Pelvic Tilt Is Associated With Dynamic Pelvic Tilt During Running When Measured by 3-Dimensional Motion...

Area of Science:

• Biomechanics
• Kinesiology
• Sports Medicine

Background:

• Standing pelvic tilt (PT) is biomechanically linked to injury risks like dynamic knee valgus.
• Limited research exists on the relationship between standing PT and dynamic PT.
• The criterion validity of the palpation meter (PALM) for measuring standing PT against 3D motion analysis is not well-established.

Purpose of the Study:

• To determine the criterion validity of the PALM for measuring standing PT.
• To identify the relationship between standing PT and dynamic PT during running.

Main Methods:

• Twenty-five participants (10 males, 15 females) had their standing PT measured using the PALM and 3D motion analysis.
• Dynamic PT variables were assessed at initial contact and toe-off during running.
• Statistical analysis examined the relationship between the two measurement tools and between standing and dynamic PT.

Main Results:

• No significant relationship was found between standing PT measurements from the PALM and 3D motion analysis, indicating the PALM is not a valid alternative.
• Significant, large positive correlations were observed between standing PT and dynamic PT at both initial contact (r = .751) and toe-off (r = .761).

Conclusions:

• The PALM is not a valid tool for assessing standing pelvic tilt when compared to 3D motion analysis.
• Clinicians can utilize standing PT measurements to gain insights into dynamic PT, potentially guiding decisions for further biomechanical assessments during running analysis.
