Walking with wider steps increases stance phase gluteus medius activity
Kinematic characteristics of human walking are commonly used to identify atypical gait patterns, and may provide insight into the underlying deficits. For example, an increased step width has been reported with increased age [1,2] and in patients post-stroke [3,4]. Walking with wide steps increases the metabolic rate [5,6], raising the question of why individuals would walk with this less economical gait pattern.

Physiologically corrected coupled motion during gait analysis using a model-based approach
Gait analysis is a common tool used in daily clinics to evaluate patient's functions, to help diagnosis and to assure follow-up after medical interventions related to various disorders (e.g. stroke, Parkinson disease, cerebral palsy, …). Stereophotogrammetric devices, using reflective markers set on the subject's skin, are the most popular tools used to perform such analyses [1]. The accuracy of these devices is excellent with respect to the position of the markers in 3D space [2]. However results must be carefully interpreted because accuracy of such systems is still controversial due to the error induced by marker placement [3,4].

Modelling the recovery of acute stroke survivors during adaptive robot-assisted training
In this study, the analysis of the trial-by-trial performance highlighted three main aspects of the recovery process: learning, retention, and slacking.

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].

Reaching tasks in an altered dynamic environment: Motor adaptation in FRDA patients
Introduction: In the last few years, robotic devices are extensively employed to exploit how the Central Nervous System (CNS) learns to control movements in different dynamical conditions. It was demonstrate that normally developed subjects can adapt to novel dynamic environments, tuning an internal model of the arm environment to compensate systematically applied forces, and showing an after-effect that appears when the force field is unexpectedly removed [1]. It was also found that this capability is at least partially still present in subjects affected by Huntington's disease, or in stroke survivor, but not in subjects ...

Effects of dual task on turning ability in stroke survivors and older adults
The ability to turn while walking, whether to avoid an obstacle or navigate corners, is an integral component of independent mobility. Turning accounts for as many as 45% of steps taken daily [1] and is a risky manoeuvre in which stroke survivors frequently fall [2]. Although falls while turning are more likely to be injurious than during other events [3] and stroke survivors’ are at high risk of injury from falling [4], few studies have examined the mechanisms underlying falls during turning following stroke.

Assessment of arm movements during gait in stroke – The Arm Posture Score
Approximately 80% of stroke survivors in Sweden experience walking problems three months post stroke [1]. Arm movements are often affected and recent research emphasizes that arm movements should be addressed during gait rehabilitation [2–4]. However, assessments used in stroke rehabilitation rarely evaluate arm movements during walking.
