Wearable airbags are a promising new technology that may help mitigate fall-related injuries. These devices use motion sensors, pre-impact fall detection algorithms, and CO<sub>2</sub>-powered airbags to cushion the impact of a fall. However, this technology is only needed for people with a high risk of falls, and it is only useful if the pre-impact fall detection algorithm successfully detects the fall. Our prior work showed that some individuals benefit more from one pre-impact fall detection algorithm than another due to their unique movement characteristics and biomechanics. This study aims to determine who may be suitable users for this technology by predicting future fall risk and categorizing users as 'responders' or 'non-responders' based on their predicted algorithm performance. We recruited 22 participants with neurological conditions in a six-month study design. Using baseline physical assessments, survey scores, and principal component analysis, we trained a logistic regression model that distinguished high-risk 'fallers' from 'non-fallers' with an average F1 score of 0.76. The model also identified 'responder' individuals, whose fall patterns were accurately detected, achieving an F1 score of 0.75. These findings suggest that identifying high fall risk users whose falls are best identified by a fall detection algorithm can enhance device effectiveness and maximize benefits for users.</p>","PeriodicalId":73276,"journal":{"name":"IEEE ...

This discrepancy prevents the direct translation of emerging biomimetic control methods for powered knee-ankle prostheses, which implicitly assume both joints exhibit normative biomechanics. To enable commercial prostheses to benefit from biomimetic control methods on inclines, this paper adapts a continuous knee kinematic model to minimize the difference in global foot angle compared to able-bodied reference data, under the assumption that the ankle joint is locked. In a pilot experiment with an above-knee amputee participant, our adapted controller produced substantial benefits compared to a baseline controller that only tracks ablebodied knee trajectories. Level-ground walking performance is similar to existing methods despite the change of objective, and on steep inclines, prosthesis load-bearing and center of pressure progression are restored to near-normative levels.

Additionally, robotic assistance must accommodate the complex, coordinated upper limb motions required for ADL tasks, including not only isolated hand movements but also integrated hand and wrist actions. This paper presents a multimodal human-machine interface (HMI) for integrated hand-wrist rehabilitation using both EEG and EMG signals. A three-degrees-of-freedom (3-DOF) soft wearable robot, combining a robotic hand glove and forearm skin brace, was designed to assist coordinated hand and wrist movements during reaching and grasping. EEG signals classified rest and grasp states using a Riemannian geometry approach, while EMG signals from three forearm muscles detected reaching onset to trigger the wrist adjustment. Preliminary tests with four healthy participants demonstrated 85% accuracy in EEG-based classification and sufficient EMG amplitude for motion onset detection.

High intra-class coefficient values (>0.9) further constitute the system's consistency and accuracy in UE movement over time. These results suggest that CLEVERArm can reliably replicate input trajectories, providing consistent and positive outcomes in rehabilitation settings.

We hypothesized that visual characterization of physics-based musculoskeletal predictive simulations of walking would be sensitive to the biomechanical objective employed by individuals, as well as the visual perspective. We developed 75 full-body muscle-driven predictive gait simulation videos, corresponding to five subject models, five biomechanical objectives, and three visual perspectives. Subject models were constructed for five individuals performing straight line walking, with optimal tracking simulations generated for each using computed muscle control. Direct collocation was used to apply five different objectives to each individual's nominal behavior including metabolic cost, summed and squared muscle activations, time-integrated whole-body angular momentum, time-integrated bilateral ground reaction forces, and an equally weighted multi-objective cost function summing the individual objectives. 100 crowd workers characterized each simulation on a 1-5 scale using stylistic labels corresponding to each objective. Multinomial logistic regression analysis revealed that loading and activation ratings were significant predictors of muscle activation-optimized movements, while activation ratings were significant predictors of movement perspective. Balance ratings were significant for the frontal view alone, suggesting that balance indicators are more easily distinguished in the frontal plane. Collectively, the wisdom of crowds could distinguish motion associated with some biomechanical objectives, but due to the redundancy of motor control strategies used by individuals, the resolution of this observational approach is limited.</p>","PeriodicalId":73276,"journal":{"name":"IEEE ...

Restricted mobility due to these deficits and the lack of adaptive rehabilitative solutions make traversing complex and challenging terrains unsafe. Exoskeletons offer a promising solution, but their effectiveness could be greatly enhanced by incorporating reinforcement learning algorithms for real-time adaptation to changing environments and the user's unique gait biomechanics. This study explored different temporal difference learning methods for predicting signals recorded from sensors on the lower-limbs, including muscle activation from electromyography, underfoot pressure, and joint angles from goniometers. Specifically, the performance of the temporal difference learning methods TD $(lambda)$, TOTD, and SwiftTD to quickly and accurately predict these signals was examined. From initial findings, SwiftTD generally converged faster, while TOTD typically achieved lower convergence errors. These outcomes varied depending on the specific signal that was being predicted, highlighting the need for careful consideration of algorithm choice depending on the signal, accuracy, and speed. The results, therefore, support the informed selection of specific algorithms for providing predictive knowledge to adaptive, machine learning-controlled assistive rehabilitative technologies.

Electroencephalography (EEG) is a standard approach for acquiring such brain signals due to its low cost and high temporal resolution. EEG signals can be thought of as a proxy for the user's intent. One established method for translating this intent into inferences and actions are neural networks. However, densely connected neural networks can be computationally expensive-a problem for real-time, deployed brain-body-machine interface systems. In this paper we investigate the use of sparsity in neural networks for EEG-based motor classification, with the goal of reducing the number of neuronal connections without sacrificing a system's performance. We compare two sparsity-inducing algorithms, weight pruning and sparse evolutionary training, with a dense neural network under three experimental conditions. Overall, our results show that sparse neural networks can achieve higher performance accuracy and generalization than their densely-connected counterparts for an EEG-based classification task. We found that sparse evolutionary training achieves the highest and most stable performance across all experiments. Introducing sparsity into the network is a viable option for efficient EEG-based control, with promising applications in a range of related rehabilitation and assistive technologies.
