Kinematic variability and number of trials for studying sitting stability with spinal cord injury

Résumé

In Spinal Cord Injury (SCI), maintaining the body stability is challenging due to lack of muscular activity in their lumbar level compared with healthy individuals, which makes them vulnerable during daily activities. Sitting stability is crucial in functional activities, such as wheelchair-related skills, propulsion and transfers in daily life (Potten et al. 1999). It is associated with both level and completeness of the SCI which determines the intensity of sensory, motor impairments and also sitting balance strategy (Gagnon et al. 2008; Milosevic et al. 2015). There are several methods for assessing sitting stability in persons living with SCI. Multiple studies (Potten et al. 1999) used voluntary motor activities, albeit other studies (Blandeau et al. 2020) used resisting unexpected perturbation for understanding the underlying mechanism of sitting stability in SCI people. In both cases, these studies are based on the repetition of experimental acquisitions. Finding the Minimum Number of Trials (MNT) not only does shorten the time of testing, but also reduces the risk for any potential injury during acquisitions. Previous studies used different strategies for finding the MNT in clinical tests. Severing et al (Severin et al. 2021) calculated the MNT in 10 recreational golfers during swing. In their study they used various reliability methods like sequential analysis method (SAM) and intraclass correlations (ICC) on the kinetic kinematic data. Same as the aforementioned study, the purpose of this study is to determine the MNT to achieve stability of variables studied in clinical tests of SCI by SAM and ICC methods.
