Though walking impairments are prevalent in society, clinical treatments often ineffective at restoring lost function. For this reason, researchers have begun to explore the use of patient-specific computational models develop more effective treatments. However, accuracy with which can predict internal body forces muscles and across joints depends on how well relevant model parameter values be calibrated for patient. This study investigated knowledge knee contact affects calibration...
Abstract Duchenne muscular dystrophy (DMD) and spinal atrophy (SMA) are neuromuscular diseases that lead to progressive muscle degeneration weakness. Recent therapeutic advances for DMD SMA highlight the need accurate clinical evaluation. Traditionally, motor function of upper limbs is assessed using scales. However, these scales influenced by clinician’s interpretation may lack accuracy. For this reason, clinicians becoming interested in finding alternative solutions. In context, Inertial...
Studies on robotic interventions for gait rehabilitation after stroke require: (i) rigorous performance evidence; (ii) systematic procedures to tune the control parameters; and (iii) combination of modes. In this study, we investigated how individuals responded training two weeks with a knee exoskeleton (ABLE-KS) using both Assistance Resistance modes together auditory feedback train peak flexion angle. During training, torque provided by ABLE-KS biofeedback were systematically adapted based...
Abstract Recovering the ability to stand and walk independently can have numerous health benefits for people with spinal cord injury (SCI). Wearable exoskeletons are being considered as a promising alternative conventional knee-ankle-foot orthoses (KAFOs) gait training assisting functional mobility. However, comparisons between these two types of devices in terms biomechanics energetics been limited. Through randomized, crossover clinical trial, this study compared use knee-powered lower...
The dynamic simulation of incomplete spinal cord injured individuals equipped with active orthoses is a challenging problem due to the redundancy simultaneous human-orthosis actuation. objective this work two-fold. Firstly, physiological static optimization approach solve muscle-orthosis actuation sharing presented. For purpose, biomechanical model based on multibody dynamics techniques used. muscles are modeled as Hill-type actuators and atrophy denervated considered by adding stiff...
Abstract Walking rehabilitation using exoskeletons is of high importance to maximize independence and improve the general well-being spinal cord injured subjects. We present design control a lightweight modular robotic exoskeleton assist walking in subjects who can hip flexion, but lack knee ankle muscles. The developed prototype consists two orthoses, which are powered by motor-harmonic drive actuation system that controls flexion–extension. This module assembled on standard passive...
Recent studies on ankle exoskeletons have shown the feasibility of this technology for post-stroke gait rehabilitation. The main contribution present work is a comprehensive experimental analysis and protocol that focused evaluating wide range biomechanical, usability users' perception metrics under three different walking conditions: without exoskeleton, with an exoskeleton unpowered, powered. To carry out study, we developed ABLE-S can provide time-adapted plantarflexion dorsiflexion...
Abstract This paper contains a joint study of two sentential logics that combine many-valued character, namely tetravalence, with modal character; one them is normal and the other quasinormal. The method to their algebraic counterparts abstract models tools Algebraic Logic, particularly those Brown Suszko's theory as recently developed by Font Jansana in “A General Semantics for Sentential Logics”. studied here arise from lattice-theoretical properties we review Tetravalent Modal Algebras,...
