To promote early rehabilitation of walking, gait training can start even when patients are on bed rest. Supine stepping in the early phase after injury is proposed to maximise the beneficial effects of gait restoration. In this training paradigm, mechanical loading on the sole of the foot is required to ...

Error-based learning (EBL) involves gradually reducing movement errors caused by a perturbation. When the perturbation has been unexpectedly removed, exaggerated movements occur in the opposite direction of a perturbation effect, known as after effects. Our goal was to determine whether the perturbation type impacts error-reduction or after effects in swallowing ...

Neuromuscular electrical stimulation (NMES) has been shown to impart a number of health benefits and can be used to produce functional outcomes. However, one limitation of NMES is the onset of NMESinduced fatigue. Multi-channel asynchronous stimulation has been shown to reduce NMES-induced fatigue compared to conventional single-channel stimulation. However, in ...

When hedonic contrast causes stimuli to become less good, it also reduces subjects' preferences between them (hedonic condensation). Here we investigated whether the reduction in preference is a by-product of hedonic contrast or can occur as a result of other manipulations that increase the negativity of the stimuli. Subjects smelled ...
