Exploration of arm weight effects on hemiparetic stroke participants' gait performance
This study's exploratory results demonstrate arm weight's potential for improving higher-functioning stroke survivors' gait performance. Arm weight addition merits further investigation as a possible rehabilitation intervention in the stroke population.

Effect of power training on rate of torque development and spatiotemporal gait parameters post stroke
This study aimed to determine effect of power training on paretic and non-paretic limb torque parameters, spatiotemporal gait parameters, and walking speed in chronic stroke survivors.

A systematic review of perturbation-based balance training on reducing fall risk among individuals with stroke
The existing evidence does not conclusively support the reduction in falls and improvements in fall risk factors resulting from perturbation-based balance training among people with stroke. Such an inconsistent finding could be due to the small sample sizes and variations in perturbation-based balance training protocols across studies. More high-quality studies are needed to further determine the effects of perturbation-based balance training on reducing fall risk in people with stroke.

Quantitative assessment of thenar to evaluate hand function after stroke by Bayes discriminant
The incidence rate of stroke or cerebrovascular accidents ranks first in China. More than 85% of stroke patients have residual upper limb motor dysfunction, especially hand dysfunction. Normalizing the rehabil...

A robotic system for quantitative assessment and post-stroke training of forelimb retraction in mice
Introduction: Neurorehabilitation protocols based on the use of robotic devices have recently shown to provide promising clinical results. However, their efficacy is still limited due to the poor comprehension of the mechanisms at the basis of functional enhancements. Here, we aimed to increase basic understanding of robot-mediated neurorehabilitation by performing experiments on a rodent model of stroke.

Training and assessment of upper limb motor function with a robotic exoskeleton in chronic stroke patients
This study presents a clinical controlled evaluation study conducted in a small group of chronic stroke patients to compare robotic therapy delivered with a robotic exoskeleton to physical therapy. The goal of the study was twofold, on one side comparing the efficacy of robotic treatment vs manual physical therapy, on the other side investigating through some kinesiologic and functional measurements associated to upper limb movement the effects of robotic training in motor recovery.

Neurophysiological evaluation in a group of post-stroke hemiparetic patients subjected to a six week robot-assisted gait training
Introduction: Robotics and related technologies have begun to realize their promise to improve the delivery of rehabilitation therapy, but the mechanism by which they enhance recovery remains unclear and the details of the recovery process is still largely unknown [1,2]. The electromechanical-driven gait orthosis Lokomat has demonstrated its feasibility and utility for gait rehabilitation after stroke, but the neurophysiological mechanisms underlying the improvement of motor function has not been deeply investigated yet [3].

Kinematic analysis of reaching and bringing a glass to the mouth in post-stroke patients
Introduction: Manual and upper limb tasks are difficult to analyse: generally such tasks are not cyclic, they are characterized by a large number of degrees of freedom and, consequently, can be performed adopting different strategies or motor patterns. These points account for a relatively small number of published studies on upper limb tasks [1], compared to the larger amount of studies on locomotor functions. In particular, the task of bringing a glass to the mouth in order to drink as performed by post-stroke patients has been considered only in one previous paper [2].

The effect of ankle–foot orthosis plantarflexion stiffness on ankle and knee joint kinematics and kinetics during first and second rockers of gait in individuals with stroke
It was suggested that those with the decreased ability to actively plantarflex their ankle could not overcome excessive plantarflexion stiffness at initial contact of gait, and as a result exhibited compensation strategies at the knee joint. Providing excessively stiff ankle–foot orthoses might put added stress on the extensor muscles of the knee joint, potentially creating fatigue and future pathologies in some patients with stroke.

The effect of progressive task-oriented training on a supplementary tilt table on lower extremity muscle strength and gait recovery in patients with hemiplegic stroke
Several studies have confirmed that lack of movement leads quickly to profound negative biomechanical and physiological changes in all systems and organs of the body [1,2]. As these patients suffering from diseases such as post-stroke and traumatic brain injury are bedridden, the instability of circulatory system occurs at an early stage of rehabilitation and leads to the appearance of atrophy and weakness in the affected leg [3]. So these musculoskeletal instabilities also lead to delayed functional training of these patients [1], it is important for these patients to be progressively mobilized and to undergo weight-suppo...

Energy flow analysis of the lower extremity during gait in persons with chronic stroke
The limited ability of those with stroke to exploit intersegmental energy transfer to optimize efficiency may limit endurance and functional independence.

Relationship between hip flexion and ankle dorsiflexion during swing phase in chronic stroke patients
These results suggest that the biomechanical behaviour of hip and ankle joints during the swing phase of the gait cycle is linked in patients with stroke. They also suggest that two strategies exist: if sufficient ankle dorsiflexion is present, less hip flexion is required (distal-strategy) whereas if dorsiflexion is reduced, it is compensated for by an increase in peak hip flexion (proximal-strategy).
