Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The central objective of this study is to validate new algorithms that coordinate between functional electrical stimulation (FES) and the exoskeleton during sitting-to-standing, walking, and standing-to-sitting movements. The secondary objective is to optimize the algorithms as well as assess their ability to reduce FES-induced muscle fatigue by using ultrasound imaging as a sensing modality. This study will include persons with no disabilities and persons with Spinal Cord Injury (SCI). A research set-up comprising of a lower-limb exoskeleton and FES system will be used to achieve sitting-to-standing, walking, and standing-to-sitting movements. Ultrasound Imaging probes may be used to record muscle activity of the stimulated muscles. The signals derived from ultrasound will be used to optimize FES in order to reduce muscle fatigue as well as assess muscle fatigue.
