Robots offer an alternative, potentially advantageous method of providing repetitive, high-dosage, and high-intensity training to address the gait impairments caused by stroke. In this study, we compared effects Stride Management Assist (SMA®) System, a new wearable robotic device developed Honda R&D Corporation, Japan, with functional task specific (FTST) on spatiotemporal parameters in stroke survivors.A single blinded randomized control trial was performed assess effect FTST task-specific...
Implicit and explicit memory systems for motor skills compete with each other during after practice. Primary cortex (M1) is known to be engaged implicit learning, while dorsal premotor (PMd) critical learning. To elucidate the neural substrates underlying interaction between systems, adults underwent a randomized crossover experiment of anodal transcranial direct current stimulation (AtDCS) applied over M1, PMd or sham sequence (serial reaction time task, SRTT) We hypothesized that M1-AtDCS...
Soft, skin-integrated electronic sensors can provide continuous measurements of diverse physiological parameters, with broad relevance to the future human health care. Motion artifacts can, however, corrupt recorded signals, particularly those associated mechanical signatures cardiopulmonary processes. Design strategies introduced here address this limitation through differential operation a matched, time-synchronized pair high-bandwidth accelerometers located on parts anatomy that exhibit...

Smartphones contain sensors that measure movement-related data, making them promising tools for monitoring physical activity after a stroke. Activity recognition (AR) systems are typically trained on movement data from healthy individuals collected in laboratory setting. However, patterns change stroke (eg, gait impairment), and activities may be performed differently at home than lab. Thus, it is important to validate AR gait-impaired patients setting accurate clinical predictions.In this...
Objective: Controlling the spread of COVID-19 pandemic largely depends on scaling up testing infrastructure for identifying infected individuals. Consumer-grade wearables may present a solution to detect presence infections in population, but current paradigm requires collecting physiological data continuously and long periods time each individual, which poses limitations context rapid screening. Technology: Here, we propose novel based recording responses elicited by short (~2 minutes)...
Spinal inhibition is significantly reduced after spinal cord injury (SCI) in humans. In this work, we examined if locomotor training can improve exerted at a presynaptic level. Sixteen people with chronic SCI received an average of 45 sessions, 5 days/wk, 1 h/day. The soleus H-reflex depression response to low-frequency stimulation, Ia afferent terminals following stimulation the common peroneal nerve, and bilateral EMG recovery patterns were assessed before training. H reflexes evoked 1.0,...

We describe clinicians' experiences, evaluations, training strategies using in spinal cord injury rehabilitation wellness settings perceptions exoskeleton benefits risks developments that would enhance utility. Methods: convened focus groups at 4 model system centers. A court reporter took verbatim notes provided a transcript. Research staff used thematic coding approach to summarize...
Regular use of prostheses is critical for individuals with lower limb amputations to achieve everyday mobility, maintain physical and psychological health, a better quality life. Use influenced by numerous factors, prosthetic design playing role in facilitating the extent mobility capabilities an amputee could achieve. Thus, can either lead safe efficient gait or biomechanically inefficient behavior. In addition increased energy expenditure, such behavior expose user risk secondary...

In humans, a chronic spinal cord injury (SCI) impairs the excitability of pathways mediating early flexor reflexes and increases late, long-lasting reflexes. We hypothesized that in individuals with SCI, locomotor training will alter behavior these spinally mediated Nine who had either clinically motor complete or incomplete SCI received an average 44 sessions. Flexor reflexes, elicited via sural nerve stimulation right left leg, were recorded from ipsilateral tibialis anterior (TA) muscle...
