Is the reliability of 3D kinematics of young obese participants dependent on the hip joint center localization method used? | LitMetric

AI Article Synopsis

  • - The study looked at test-retest reliability of 3D gait kinematics in young obese individuals using two different methods to locate the hip joint center (Davis and SCoRE) and involved ten participants with a high BMI.
  • - Participants underwent two gait analysis sessions to compare the reliability of HJC position estimations using measures like standard error of measurement (SEM) and root mean square error (RMSE).
  • - Both methods showed moderate to good reliability, but there were inconsistencies in HJC estimation (up to 5.4 cm), indicating that while they are reliable, accuracy remains a concern for future studies.

Article Abstract

The aim of this study was to investigate if the test-retest reliability for three-dimensional (3D) gait kinematics in a young obese population is affected by using either a predictive (Davis) or a functional (SCoRE) hip joint center (HJC) localization approach. A secondary goal was to analyze how consistent both methods perform in estimating the HJC position. A convenience sample of ten participants, two females and eight males with an age-based body mass index (BMI) above the 97th percentile (mean±SD: 34.2±3.9kg/m) was recruited. Participants underwent two 3D gait analysis sessions separated by a minimum of one day and a maximum of seven days. The standard error of measurement (SEM) and the root mean square error (RMSE) of key kinematic parameters along with the root mean square deviation (RMSD) of the entire waveforms were used to analyze the test-retest reliability. To get an estimate of the consistency of both HJC localization methods, the HJC positions determined by both methods were compared to each other. SEM, RMSE, and RMSD results indicate that the HJC position estimations between both methods are not different and demonstrate moderate to good reliability to estimate joint kinematics. With respect to the localization of the HJC, notable inconsistencies ranging from 0 to 5.4cm were observed. In conclusion, both approaches appear equally reliable. However, the inconsistent HJC estimation points out, that accuracy seems to be a big issue in these methods. Future research should attend to this matter.
