How can gait analysis help diagnose Parkinson's disease?5 answersGait analysis can help diagnose Parkinson's disease by analyzing the spatiotemporal gait metrics and patterns of individuals. Machine learning models, such as Convolutional Neural Networks (CNN) and Random Forest classifiers, have been used to accurately distinguish pathological gait in Parkinson's disease from that of normative controls. These models utilize data obtained from sensors that measure the virtual ground reaction force (VGRF) and extract spatiotemporal features, including swing phase, stance phase, and gait phase. By analyzing gait data, these models can classify individuals as either control or Parkinson's disease subjects and predict the severity of Parkinson's gait based on rating scales such as the Hoehn and Yahr scale and the Unified Parkinson's Disease Rating Scale (UPDRS). Gait analysis using deep learning approaches has shown promising results in detecting Parkinson's disease and can assist in its severity diagnosis.
How can gait analysis be used to design new sports equipment?5 answersGait analysis can be used to design new sports equipment by providing insights into the kinetics and kinematics of human motion. This analysis helps engineers and medical professionals understand the force and motion characteristics of individuals during gait. Tools such as motion capture systems, force platforms, and EMG are commonly used in gait analysis to collect kinetic information. Force platforms, in particular, are useful for measuring the six force and moment components exerted by each subject. By accurately measuring these forces, designers can gather data on how the musculoskeletal system is solicited and how different structures of the foot are affected. This information can then be used to simulate modifications in sports equipment characteristics and assess their influences on the strain and stress experienced by the foot. Overall, gait analysis provides valuable information that can guide the design and development of sports equipment to enhance performance and prevent injuries.
