Exoskeletal-assisted walking combined with transcutaneous spinal cord stimulation to improve bone health in persons with spinal cord injury: study protocol for a prospective randomised controlled trial.

Introduction: Persons with non-ambulatory spinal cord injury (SCI) undergo immediate unloading of the skeleton and, as a result, have marked loss of bone mineral density below the level of lesion that is directly associated with increased risk of long-bone fractures. There is a paucity of research that has successfully implemented rehabilitation and/or exercise training interventions to mitigate bone loss after acute SCI or reverse bone loss that has already occurred in chronic SCI. This paper describes a research protocol to compare the effect of exoskeletal-assisted walking (EAW) alone versus EAW plus transcutaneous spinal cord stimulation (EAW+tSCS) on bone density, geometry and strength in a cohort of chronic SCI participants.

Insights into COVID-19 pathophysiology from a longitudinal multisystem report during acute infection.

The Coronavirus disease 2019 (COVID-19), an illness caused by a SARS-CoV-2 viral infection, has been associated with neurological and neuropsychiatric disorders, revealing its impact beyond the respiratory system. Most related research involved individuals with post-acute or persistent symptoms of COVID-19, also referred to as long COVID or Post-Acute Sequelae of COVID-19 (PASC). In this longitudinal unique report, we aimed to describe the acute supraspinal and corticospinal changes and functional alterations induced by a COVID-19 infection using neuroimaging, neurophysiological and clinical assessment of a participant during acute infection, as compared to three other visits where the participant had no COVID-19.

Effects of Robotic Postural Stand Training with Epidural Stimulation on Sitting Postural Control in Individuals with Spinal Cord Injury: A Pilot Study.

(1) . High-level spinal cord injury (SCI) disrupts trunk control, leading to an impaired performance of upright postural tasks in sitting and standing. We previously showed that a novel robotic postural stand training with spinal cord epidural stimulation targeted at facilitating standing (Stand-scES) largely improved standing trunk control in individuals with high-level motor complete SCI.
