Objectives: Mental practice, as a neuropsychological factor effective in motor recovery, is a cognitive rehearsal of a physical skill without muscular activity. Considering the high level of fatigue in patients with Multiple Sclerosis (MS), we hypothesized that using mental practice as a low-level energy-consuming method added to physical practice could be a useful therapeutic strategy. Therefo...

For the impulsive ankle push-off (APO) observed in human walking two muscle-tendon-units (MTUs) spanning joint play an important role: Gastrocnemius (GAS) and Soleus (SOL). GAS SOL load Achilles tendon to store elastic energy during stance followed by a rapid release APO. We use neuromuscular simulation (NMS) bipedal robot investigate role of on optimize for robust gait then sequentially replac...

In many simple walking models, foot placement dictates the center of pressure location and ground reaction force components, whereas humans can modulate these aspects after foot contact. Because of the differences, it is unclear to what extent predictions made by models are valid for human walking. Yet, both model simulations and human experimental data have previously indicated that the center...

BACKGROUND A previous comprehensive prehabilitation program, providing nutrition counseling with whey protein supplementation, exercise, and psychological care, initiated 4 weeks before colorectal surgery for cancer, improved functional capacity before surgery and accelerated functional recovery. Those receiving standard of care deteriorated. The specific role of nutritional prehabilitation alo...

The ostrich is highly specialized in terrestrial locomotion and is the only extant bird that is both didactyl and exhibits a permanently elevated metatarsophalangeal joint. This extreme degree of digitigrady provides an excellent opportunity for the study of phalangeal adaptation towards fast, sustained bipedal locomotion. Data were gathered in a semi-natural setting with hand-raised, cooperati...

When humans walk, the time duration of each stride varies from one stride to the next. These temporal fluctuations exhibit long-range correlations. It has been suggested that these correlations stem from higher nervous system centers in the brain that control gait cycle timing. Existing proposed models of this phenomenon have focused on neurophysiological mechanisms that might give rise to thes...

Wearable robotic devices provide safe and intensive rehabilitation, enabling repeated motions for motor function recovery in stroke patients. The aim of this small case series was to demonstrate the training effects of a three-week robotic leg orthosis, and to investigate possible mechanisms of the sensory-motor alterations and improvements by using gait analysis and EMG. Three survivors of chr...
