“…The absolute measure of reliability standard error of measurement (SEM) was calculated using the following equation: SEM = SD diff / √ 2. The indicated levels of error for kinematic data were considered acceptable if SEM ≤ 2 • , reasonable between 2 • and 5 • , and concerning if SEM ≥ 5 • [20]. From each trial, 97 individual values of clinical interest were extracted.…”

“…The six-degree-of-freedom (6DoF) models are the most common alternative to the CGM that, despite needing more extensive validation [18], assumes that the segments are rigid and do not constrain the joints motions [19]. Several 6DoF modeling techniques were used in the assessment of repeatability in participants with motor and physical characteristics limiting the normal gait [14,20,21].…”

Background: Cerebral palsy (CP) is a complex pathology that describes a group of motor disorders with different presentations and functional levels. Three-dimensional gait analysis is widely used in the assessment of CP children to assist in clinical decision making. Thus, it is crucial to assess the repeatability of gait measurements to evaluate the progress of the rehabilitation process. The purpose of the study is to evaluate test-retest reliability of a six-degree-of-freedom (6DoF) marker set in key points of gait kinematics, kinetics, and time-distance parameters in children with CP. Methods: trials were performed on two different days within a period of 7.5 ± 1.4 day. Motion capture data was collected with 14 infrared, high-speed cameras at a frequency rate of 100 Hz, synchronized in time and space with two force plates. Intraclass correlation coefficients considering the two-way mixed model, and absolute agreement (ICC[A,k]) were calculated for anthropometric, time–distance, kinematic and kinetic parameters of both lower limbs. Results: the majority of gait parameters demonstrated a good ICC, and the lowest values were in the kinematic variables. Conclusions: this study indicates wide-ranging reliability values for lower limb joint angles and joint moments of force during gait, especially for frontal and transverse planes. Although the use of a 6DoF-CAST in CP children was shown to be a feasible method, the gait variation that can be observed between sessions in CP children seems to be related not only to the extrinsic factors but also to their different gait patterns and affected sides.

“…Gait analysis in about 18 children with CP (GMFCS I to III) has also been performed using 2D markerless protocol based on RGB-D sensor and validated with a marker-based photogrammetric system [20]. 3D gait analysis with a marker system was used to assess kinematic parameters by walking test of children with CP to determine the reliability of the results [21]. Gait analyses have also been used to support surgical recommendations and decision-king in patients with CP [13].…”

Children with cerebral palsy do not present normal posture and movement patterns, so it is required to improve them. This work aims to show the differences in the trunk and ankles kinematics during the gait cycle of children with dystonic cerebral palsy, GMFCS level IV, using an assistive device and without using it, and to demonstrate how certain systems of the assistive device contribute to the children's gait trajectory control. The assistive device is a walker-type prototype designed under physical therapists' requirements. Walking tests were performed using marker protocol on the assistive device to assess its anti-return and directional locking systems. Gait Analysis were carried out with the child under two conditions, the walk assisted by two individuals and the walk using the assistive device. Two marker protocols were established. Recorded information was analyzed using motion analysis software. The elevation of each ankle and the trend of trunk angle variation concerning the vertical in the sagittal plane are determined for gait cycles with and without the prototype's aid. The results showed that the subject could perform the walking with the assistive device by himself. The line of progression presented lesser lateral deviations and a homogeneous frontal stride when the assistive device was used than without it. The anterior trunk and pelvic tilt increased by 19° to 28° in comparison to the walk with the assistance of people.
