Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to assess whether gait classification patterns can be reliably obtained from video recordings in comparison with three-dimensional kinematic data.

The main questions it aims to answer are:

Are gait classifications from video recordings reliable between raters? Are gait classifications from video recordings valid in comparison with three-dimensional kinematic data?

Gait analysis data from participants who visited the gait lab in the Karolinska Hospital will be used for this purpose.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Current retrospective observational study aims to assess the reliability and validity of gait pattern classification systems in ambulatory children with CP. Gait classification is often performed using kinematic gait data obtained via a three dimensional (3D) data captured in a specialized gait lab using infra-red cameras. However, not all hospitals and clinical centers have access to such a specialized gait lab, and therefore often use video recordings as an alternative for gait classification. It is currently not known whether such a classification based on solely video recordings is equally reliable in comparison with kinematic gait data. For this purpose, current study aims to assess the reliability and validity of video recordings to classify children with CP according to predefined gait classifications. Sagittal plane video recordings during barefoot walking in children with CP will be used to classify the study participants into seven different gait classification patterns. For reliability, inter-rater reliability between raters scoring the video recordings will be assessed. To evaluate whether video recordings could serve as a valid alternative for kinematic gait data, the agreement between the classifications from the video recordings and the kinematic data additionally will be assessed.
