“…However, the COM position with respect to the segmental coordinate system is generally predicted via regression equations with a full-body marker set in traditional optoelectronic motion capture systems [68]. It was found that COM positions decided by 7-9 multisegmental models allow a compromise between feasibility and accuracy when assessing the dynamic stability [69]. Similar anthropometric models and statistically equivalent serial chain methods have been developed to improve the COM estimation of the Kinect [70].…”

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.

“…16 It must be noted that a recent review of poststroke gait stability highlighted how the widening of the steps does not improve stability in persons with stroke and pointed out the need to study the stability of both limbs. 28 However, the adoption of a cautious gait strategy to improve stability through slower walking, with shorter step length, and wider step widths, seems not sufficient since falls still occur. Therefore, there is a need to further investigate gait stability and identify appropriate measures to design new rehabilitative interventions aimed at reducing fall risk.…”

Maintaining a stable gait requires a dynamic balance control, that can be altered in persons with Multiple Sclerosis (MS), Stroke (ST), and Parkinson’s disease (PD). The understanding of the strategy for Center of Mass (CoM) positioning adopted by patients during walking is important to be able to program treatments aimed at improving gait control and preventing falls. Forty-four persons with a mild-to-moderate neurological disorder (20 with MS, 14 with ST, 10 with PD) underwent clinical examination and gait analysis. Ten Healthy Subjects (HS) walking at matched speed provided the normative data. Dynamic balance was assessed using the margin of stability (MoS). It was calculated as the distance between the extrapolated Center of Pressure and the extrapolated CoM at mid-stance. The MoS values for lower limbs were calculated in patients and compared with speed-matched values of HS. Persons with neurological disorder showed increased MoS in the medio-lateral direction with respect to HS. Within-group comparison analysis showed a symmetry between lower limbs in HS (Mean (95%CI) [mm], dominant vs non-dominant limb, 43.3 (31.9–54.6) vs 42.9 (28.8–56.9)) and PD (less affected vs more affected limb, 71.1 (59.8–82.5) vs 72.5 (58.5–86.6)), while a significant asymmetry was found in MS (54.4 (46.4–62.4) vs 81.1 (71.2–91.1)) and ST (52.1 (42.6–61.7) vs 74.7 (62.8–86.6)) participants. The history of falls was comparable among PD, MS, and ST groups, and the MoS in the frontal plane showed a strong correlation with these records. Objective assessment of MoS revealed pathology-specific strategies showing different impacts in MS, ST, and PD on the ability to control CoM information to manage the balance between limbs during gait. MoS evaluation will provide useful information to address a tailored rehabilitation program and to monitor disease progression.

“…As we see in Table 1.1, there are a number of balance control metrics in literature (Bruijn et al, 2013;Devetak et al, 2019). Bruijn and colleagues did not address the final group G3, as these metrics were subject to the type and intensity of perturbations applied (Bruijn et al, 2013).…”

“…Each of these systems measure an aspect of movement such as muscle activation (T1), generation of force or measuring reactive force (T2), and movement of body segments (T3). Optical measurement systems and force plates are usually considered to be gold standards for measuring movement General Introduction kinematics and ground reaction forces respectively (Baker, 2006;Devetak et al, 2019).…”
