AdjuSST: An Adjustable Surface Stiffness Treadmill.

Humans have the remarkable ability to manage foot-ground interaction seamlessly across terrain changes despite the high dynamic complexity of the task. Understanding how adaptation in the neuromotor system enables this level of robustness in the face of changing interaction dynamics is critical for developing more effective gait retraining interventions. We developed an adjustable surface stiffness treadmill (AdjuSST) to trigger these adaptation mechanisms and enable studies to better understand human adaptation to changing foot-ground dynamics.

Gait Adaptation to Asymmetric Hip Stiffness Applied by a Robotic Exoskeleton.

Wearable exoskeletons show significant potential for improving gait impairments, such as interlimb asymmetry. However, a more profound understanding of whether exoskeletons are capable of eliciting neural adaptation is needed. This study aimed to characterize how individuals adapt to bilateral asymmetric joint stiffness applied by a hip exoskeleton, similar to split-belt treadmill training.

Bilateral asymmetric hip stiffness applied by a robotic hip exoskeleton elicits kinematic and kinetic adaptation.

Wearable robotic exoskeletons hold great promise for gait rehabilitation as portable, accessible tools. However, a better understanding of the potential for exoskeletons to elicit neural adaptation-a critical component of neurological gait rehabilitation-is needed. In this study, we investigated whether humans adapt to bilateral asymmetric stiffness perturbations applied by a hip exoskeleton, taking inspiration from asymmetry augmentation strategies used in split-belt treadmill training.

Correction to: Audiotactile integration in the Pacinian corpuscle's maximum sensitivity frequency range.

The article was published with a typo in the article title. The word "corpusclel's" should read "corpuscle".

Audiotactile integration in the Pacinian corpusclel's maximum sensitivity frequency range.

It has been shown that vibrotactile stimuli elicit sound perception either on their own or by enhancing otherwise inaudible sounds. For taking advantage of this phenomenon in the design of vibrotactile interfaces, it is important to identify its properties with respect to the level of the excitation frequency. The aim of this work is to further substantiate previous research results that indicate a prevalence of this phenomenon at a specific range of frequencies (200-390 Hz), which roughly pertains to the Pacinian corpuscle's maximum sensitivity range.
