This study found that measuring pelvic tilt in the sagittal plane using a specific method demonstrates very high intertester reliability. This reliable method is effective for assessing pelvic tilt angles and ranges of motion.

Area of Science:

  • Biomechanics
  • Kinesiology
  • Physical Therapy

Background:

  • Pelvic tilt is a critical component of sagittal plane biomechanics.
  • Accurate measurement of pelvic tilt is essential for clinical assessment and research.
  • Intertester reliability of measurement techniques is crucial for consistent clinical practice.

Purpose of the Study:

  • To evaluate the intertester reliability of a specific method for measuring pelvic tilt angles and ranges of motion.
  • To assess the reliability of measuring relaxed standing pelvic-tilt angle, active anterior and posterior pelvic-tilt angles, and total pelvic-tilt range of motion (ROM).

Main Methods:

  • Six testers measured pelvic tilt parameters on 12 subjects after standardized instruction.
  • Pelvic-tilt angles were calculated using trigonometric functions.

  • Range of motion (ROM) in degrees was derived from measured pelvic-tilt angles.

    • Main Results:

    • High intraclass correlation coefficients (ICCs) were reported for all measured parameters.
    • ICCs ranged from 0.88 for anterior pelvic-tilt ROM to 0.95 for standing pelvic-tilt angle.
    • Specific ICCs: standing pelvic-tilt angle (.95), anterior pelvic-tilt angle (.93), posterior pelvic-tilt angle (.93), anterior pelvic-tilt ROM (.88), posterior pelvic-tilt ROM (.93), total pelvic-tilt ROM (.90).

    Conclusions:

    • The tested method for measuring pelvic tilt in the sagittal plane demonstrates very high intertester reliability.
    • This finding supports the use of this method for consistent and dependable clinical assessments of pelvic tilt.
    • The high reliability indicates the method's suitability for research investigating sagittal plane pelvic biomechanics.
