“…The low-cost, infrared camera Kinect v2 enables the motion tracking of the main joints of the human body, without requiring wearable markers. The potential for the Kinect v2 to determine the spatiotemporal and kinematic variables associated with gait has been also investigated in patients with neurological diseases, with promising results [ 21 – 25 ]. Research has also shown good agreement between the Kinect and a laboratory-grade three-dimensional motion analysis system during measurements of movements of individuals with PD [ 26 ].…”

“…Research has also shown good agreement between the Kinect and a laboratory-grade three-dimensional motion analysis system during measurements of movements of individuals with PD [ 26 ]. However, existing studies examining individuals with PD have included limited numbers of participants [ 21 , 22 , 25 ], which limits the ability to extrapolate results, or have only investigated specific parameters, without performing comprehensive postural or gait assessments [ 21 , 22 , 25 ].…”

Background Accurate assessment of balance and gait is necessary to monitor the clinical progress of Parkinson’s disease (PD). Conventional clinical scales can be biased and have limited accuracy. Novel interactive devices are potentially useful to detect subtle posture or gait-related impairments. Methods Posturographic and single and dual-task gait assessments were performed to 54 individuals with PD and 43 healthy controls with the Wii Balance Board and the Kinect v2 and the, respectively. Individuals with PD were also assessed with the Tinetti Performance Oriented Mobility Assessment, the Functional Gait Assessment and the 10-m Walking Test. The influence of demographic and clinical variables on the performance in the instrumented posturographic and gait tests, the sensitivity of these tests to the clinical condition and phenotypes, and their convergent validity with clinical scales were investigated. Results Individuals with PD in H&Y I and I.5 stages showed similar performance to controls. The greatest differences in posture and gait were found between subjects in H&Y II.5 and H&Y I–I.5 stage, as well as controls. Dual-tasking enhanced the differences among all groups in gait parameters. Akinetic/rigid phenotype showed worse postural control and gait than other phenotypes. High significant correlations were found between the limits of stability and most of gait parameters with the clinical scales. Conclusions Low-cost devices showed potential to objectively quantify posture and gait in established PD (H&Y ≥ II). Dual-tasking gait evaluation was more sensitive to detect differences among PD stages and compared to controls than free gait. Gait and posture were more impaired in akinetic/rigid PD.

“…Besides, Kinect v2 has shown better global performance regarding accuracy and stable data (Gonzalez-Jorge et al 2015). An increasing number of studies have focused on spatiotemporal gait analysis with these devices in post-stroke individuals (Vernon et al 2015;Clark et al 2012;Cao et al 2017). However, variability in populations, measures, and methodologies prevents adequate comparison of the results.…”

Different studies have analyzed the potential of the off-the-shelf Microsoft Kinect, in its different versions, to estimate spatiotemporal gait parameters as a portable markerless low-cost alternative to laboratory grade systems. However, variability in populations, measures, and methodologies prevents accurate comparison of the results. The objective of this study was to determine and compare the reliability of the existing Kinect-based methods to estimate spatiotemporal gait parameters in healthy and post-stroke adults. Forty-five healthy individuals and thirty-eight stroke survivors participated in this study. Participants walked five meters at a comfortable speed and their spatiotemporal gait parameters were estimated from the data retrieved by a Kinect v2, using the most common methods in the literature, and by visual inspection of the videotaped performance. Errors between both estimations were computed. For both healthy and post-stroke participants, highest accuracy was obtained when using the speed of the ankles to estimate gait speed (3.6-5.5 cm/s), stride length (2.5-5.5 cm), and stride time (about 45 ms), and when using the distance between the sacrum and the ankles and toes to estimate double support time (about 65 ms) and swing time (60-90 ms). Although the accuracy of these methods is limited, these measures could occasionally complement traditional tools.

“…This tool enables the noninvasive, quantitative, objective, and accurate evaluation of motor impairments. Previously, gait analyses using Kinect V2 were reported in stroke or Parkinson's disease subjects, although subjects with cerebellar ataxia have not been similarly assessed with the exception of one study that analyzed juvenile and infantile-onset cerebellar ataxia [16][17][18][19][20][21].…”

Background: Cerebellar ataxia including spinocerebellar ataxia and Parkinson's disease are neurodegenerative disorders clinically characterized by motor disabilities including gait disturbance. This study aimed to investigate the usefulness of an infrared depth sensor device to quantitatively evaluate gait disturbances and assess its cost effectiveness in patients with movement disorders. Methods: Twenty five ataxic, twenty five Parkinson's disease, and twenty five control subjects were enrolled and evaluated their walk over a short distance. Stride length, feet interval, gait rhythm, and a ratio of the actual walking route length to the linear distance between the start and goal points (A/L ratio) were assessed and compared between ataxic or Parkinson's disease subjects and control subjects. Outcome correlations with clinical scales were also analyzed in the disease groups. Results: The average stride length was shorter in ataxic subjects or Parkinson's disease subjects than in control subjects. The average feet interval was larger in ataxic subjects than in control subjects. The stride length coefficient of variation (CV), gait rhythm CV, and average and standard deviations of the A/L ratio were larger in ataxic or Parkinson's disease subjects than in control subjects. Ataxic subjects exhibited significant positive correlations between the CV of stride length or average feet interval and scale for the assessment and rating of ataxia scores or international cooperative ataxia rating scale scores. Parkinson's disease subjects exhibited a significant correlation between the average stride length, CV of stride length, or standard deviation of A/L ratio and unified Parkinson's disease rating scale score. Conclusion: The device used in this study differentiated the characteristics of gait disturbance in each movement disorder and quantitatively evaluated ataxia or Parkinson's disease severity, indicating its potential clinical utility across applications. Background Cerebellar ataxia is clinically characterized by progressive limb and truncal ataxia, dysarthria, and gait disturbance due to neurodegeneration in the cerebellum and cerebellar systems [1,2]. Parkinson's disease is another neurodegenerative disorder, clinically characterized by rigidity, bradykinesia, tremor, impairment of righting reflexes, and gait disturbances [3]. Both cerebellar
