“…Latorre et al compared five gait event detection methods and found that the validity level varied among the selected methods for both healthy participants and stroke survivors when measuring spatiotemporal gait parameters [ 36 ]. Since MOS at midstance and mid-swing are significant indices for walking stability assessment [ 9 , 28 ], there is sufficient room for further progress in determining which gait event definition is the most appropriate one for a specific clinical group, such as children with CP, before the Kinect could be extrapolated to clinical applications.…”

“…Children with CP tend to walk inefficiently with a larger gait velocity and stride length and demonstrate an inappropriate coronal foot placement [ 8 ]. Besides, they generate more cadences, trunk compensations, and conservative lateral postural control strategies to reestablish stability when encountering perturbances during gait [ 9 , 10 , 11 ]. Improved walking ability, such as less proneness to falls, positively affects the accomplishment of life habits and social integration [ 12 , 13 ].…”

“…From the biomechanical perspective, MOS represents the “initial condition” when the subject encounters a perturbation. Compared with other stability assessment approaches that only quantify average measures, MOS is able to evaluate dynamic stability at a specific time step during locomotion [ 9 , 23 ].…”

“…With this advantage, MOS has already been widely applied to evaluate gait abnormality and fall risks in a wide range of clinical populations, including patients with stroke [ 24 ], Parkinson’s Disease [ 25 ], hereditary spastic paraparesis [ 26 ], as well as CP [ 9 , 27 ]. In a recent prospective observational study, Mehdizadeh et al found that minimum mediolateral MOS was the most important hallmark when assessing the short-term fall risk for patients with dementia [ 16 ].…”

Children with cerebral palsy (CP) have high risks of falling. It is necessary to evaluate gait stability for children with CP. In comparison to traditional motion capture techniques, the Kinect has the potential to be utilised as a cost-effective gait stability assessment tool, ensuring frequent and uninterrupted gait monitoring. To evaluate the validity and reliability of this measurement, in this study, ten children with CP performed two testing sessions, of which gait data were recorded by a Kinect V2 sensor and a referential Motion Analysis system. The margin of stability (MOS) and gait spatiotemporal metrics were examined. For the spatiotemporal parameters, intraclass correlation coefficient (ICC2,k) values were from 0.83 to 0.99 between two devices and from 0.78 to 0.88 between two testing sessions. For the MOS outcomes, ICC2,k values ranged from 0.42 to 0.99 between two devices and 0.28 to 0.69 between two test sessions. The Kinect V2 was able to provide valid and reliable spatiotemporal gait parameters, and it could also offer accurate outcome measures for the minimum MOS. The reliability of the Kinect V2 when assessing time-specific MOS variables was limited. The Kinect V2 shows the potential to be used as a cost-effective tool for CP gait stability assessment.

“…This report focuses on results from balance-reaction tests, which represent part of a larger, single-session protocol more broadly assessing balance, gait, and physical activity. Previous reports that include data from some or all of these participants focused on the relationships of age, standing sway, and balance reactions in typical development (15), gait stability in children with and without CP (16), magnetic resonance elastography (MRE) to evaluate brain stiffness of the two groups (17), and the relationships between balance reaction performance and brain stiffness in children with CP ( In Review ).…”

Aim: To compare anterior and posterior standing balance reactions, as measured by single-stepping thresholds, of children with and without cerebral palsy (CP). Method: Seventeen ambulatory children with CP and 28 typically developing children, all 5-12 years of age, were recruited for this cross-sectional, observational study. Balance reaction skill was quantified as anterior and posterior single-stepping thresholds, or the treadmill-induced perturbations that consistently elicited a step in that direction. In order to understand underlying mechanisms of between-group differences in stepping thresholds, dynamic stability was quantified using the minimum margin of stability. Ankle muscle activation latency, magnitude, and co-contraction were assessed with surface electromyography. Results: We observed large between-group differences in anterior, but not posterior, thresholds. Between-group differences were most evident in older children, with typically developing children having larger anterior thresholds than those with CP. In response to near-threshold anterior perturbations, older typically developing children recovered from more instability than their CP peers. Older children had no between-group differences in ankle muscle activity. Interpretation: The effects of CP on balance reactions are age- and direction-specific. In response to an anterior perturbation, older typically developing children recovered from more instability than their peers with CP.
