Electronics 2021, 10, 2602. https://doi.org/10.3390/ electronics10212602 Academic Editors: Syed Aziz Shah, Qammer Hussain Abbasi, Jawad Ahmad and Muhammad Ali Imran Received: four July 2021 Accepted: 22 October 2021 Published: 25 OctoberAbstract: Arm swing through gait has been positively related to gait stability and gait efficiency, particularly within the presence of neurological issues that impact locomotion. Even so, most gait research have focused on reduced extremities, when arm swing usually remains ignored. Furthermore, these research are largely primarily based on expensive, highly-specialized vision systems or on wearable devices which, regardless of their recognition among researchers and specialists, are nonetheless reasonably uncommon for the common population. This function proposes a way of estimating arm swing asymmetry from a single 2D gait video. First, two silhouette-based representations that separately capture motion data from both arms were built. Second, a measure to quantify arm swing energy from such a representation was introduced, making two side-dependent motion measurements. Third, an arm swing asymmetry index was obtained. The method was validated on two public datasets, a single with 68 healthier subjects walking ordinarily and one with 10 wholesome subjects simulating different designs of arm swing asymmetry. The validity of your asymmetry index at capturing unique arm swing patterns was assessed by two non-parametric tests: the Mann hitney U test as well as the Wilcoxon signed-rank test. The so-called physiological asymmetry was observed on the normal gait sequences of each datasets in a statistically similar way. The asymmetry index was in a position to pretty characterize the different levels of asymmetry simulated in the second set. Results show that it can be feasible to estimate the arm swing asymmetry from a single 2D gait video, with Compound 48/80 supplier adequate sensitivity to discriminate anomalous patterns from normality. This opens the door to low-cost easy-to-use mobile applications to help clinicians in monitoring gait condition in key care (e.g., in the elderly), when extra accurate and specialized technologies are typically not available.
