Ataxic gait monitoring and assessment of neurological disorders belong to important areas that are supported by digital signal processing methods artificial intelligence (AI) techniques such as machine learning (ML) deep (DL) techniques. This paper uses spatio-temporal data from Kinect sensor optimize model distinguish between ataxic normal gait. Existing ML-based methodologies fails establish feature correlation different parameters; thus, exhibit very poor performance. Further, when is imbalanced in nature the existing induces higher false positive. In addressing research issues this introduces an extreme gradient boost (XGBoost)-based classifier enhanced optimization (EFO) modifying standard cross validation (SCV) mechanism. Experiment outcome shows proposed person identification achieves good result comparison with DL-based methodologies.

Gait impairment in Parkinson's Disease (PD) is quantitatively assessed using the Movement Disorder Society Unified Rating Scale (MDS-UPDRS), a well-established clinical tool. Objective and efficient PD gait assessment crucial for developing interventions to slow or halt its advancement. Skeleton-based MDS-UPDRS score estimation has attracted increasing interest improving diagnostic efficiency objectivity. However, previous works ignore important cross-spacetime dependencies between joints gait. Moreover, existing skeleton datasets are very small, which big issue deep learning-based studies. In this work, we collect sizable dataset by multi-view Azure Kinect sensors. The collected contains 102 patients 30 healthy older adults. addition, data from 16 young adults (aged 24-50 years) further examine effect of age on assessment. For skeleton-based automatic analysis, propose novel cross-spatiotemporal graph convolution network (CST-GCN) learn complex features patterns. Specifically, labeling strategy designed assemble group neighbors root node according spatiotemporal semantics skeleton. Based strategy, CST-GCN module explicitly models among joints. Finally, dual-path model presented realize modeling fusion spatial, temporal, features. Extensive experiments validate effectiveness our method dataset.

Parkinson's disease (PD) is characterized by a variety of motor and non-motor symptoms, some them pertaining to gait balance. The use sensors for the monitoring patients' mobility extraction parameters, has emerged as an objective method assessing efficacy their treatment progression disease. To that end, two popular solutions are pressure insoles body-worn IMU-based devices, which have been used precise, continuous, remote, passive assessment. In this work, insole were evaluated impairment, subsequently compared, producing evidence support instrumentation in everyday clinical practice. evaluation was conducted using datasets, generated during study, patients with PD wore, simultaneously, pair instrumented set wearable devices. data from study extract compare features, independently, aforementioned systems. Subsequently, subsets comprised extracted machine learning algorithms impairment results indicated kinematic features highly correlated those Moreover, both had capacity train accurate models detection impairment.

Although clinician-based assessment through standardized clinical rating scales is currently the gold standard for quantifying motor impairment in Parkinson's disease (PD), it not without limitations, including intra- and inter-rater variability a degree of approximation. There increasing evidence supporting use objective motion analyses to complement assessment. Objective measurement tools hold significant potential improving accuracy research-based evaluations patients.The authors provide several examples from literature demonstrating how different tools, optoelectronics, contactless wearable systems allow both quantification monitoring key symptoms (such as bradykinesia, rigidity, tremor, gait disturbances), identification fluctuations PD patients. Furthermore, they discuss how, clinician's perspective, measurements can help various stages management.In our opinion, sufficient supports assertion that enable accurate evaluation complications PD. A range devices be utilized only support diagnosis but also monitor symptom during progression become relevant therapeutic decision-making process.

Abstract Gait impairments are among the most common and disabling symptoms of Parkinson’s disease worsen as progresses. Early detection diagnosis subtype-specific gait deficits, well progression monitoring, can help to implement effective preventive personalized treatment for PD patients. Yet, features have not been fully studied in its motor subtypes. To characterize comprehensive objective alterations identify potential biomarkers early diagnosis, subtype differentiation, severity monitoring. We analyzed parameters related upper/lower limbs, trunk lumbar, postural transitions from 24 tremor-dominant (TD) 20 instability difficulty (PIGD) dominant patients who were stage 39 matched healthy controls (HC) during Timed Up Go test using wearable sensors. Results show: (1) Both TD PIGD groups showed restricted backswing range bilateral lower extremities more affected side (MAS) arm, reduced lumbar rotation coronal plane, low turning efficiency. The receiver operating characteristic (ROC) analysis revealed these had high discriminative value distinguishing both subtypes HC with area under curve (AUC) values 0.7~0.9 ( p < 0.01).
