Scientific reports·2026

Comparing gait analysis protocols reveals variations in kinematic and kinetic measurements. While joint flexion/extension and moments show good agreement, out-of-sagittal plane rotations, especially knee abduction/adduction, exhibit discrepancies across methods.

Area of Science:

  • Biomechanics
  • Gait Analysis
  • Clinical Measurement

Background:

  • Standardized protocols are crucial for comprehensible gait analysis.
  • Existing protocols for marker-sets and biomechanical models vary significantly.
  • Comparisons of gait variables often overlook these protocol differences.

Purpose of the Study:

  • To compare five representative gait analysis protocols.
  • To analyze kinematics and kinetics of the trunk, pelvis, and lower limbs.
  • To assess the impact of different protocols on gait measurements.

Main Methods:

  • A unified marker-set (60 markers) and landmark calibration (16 landmarks) were used.
  • Kinematics and kinetics were analyzed over identical gait cycles for two healthy subjects and one patient with a knee prosthesis.

  • Five experts independently analyzed data using their respective protocols.

    • Main Results:

    • All protocols demonstrated good intra-protocol repeatability.
    • Joint flexion/extension and joint moments showed good correlations and small biases.
    • Out-of-sagittal plane rotations, particularly knee abduction/adduction, had poorer correlations and inconsistent trends.
    • One protocol showed a significant erroneous rotation at the prosthetic knee.

    Conclusions:

    • Gait analysis protocols influence kinematic and kinetic measurements, especially rotations.
    • Similar biomechanical models lead to higher inter-protocol correlations.
    • Marker-set variations appear to have less impact than biomechanical model differences.
