“…There have been efforts to develop portable rehabilitation devices (Handzic et al, 2011;Afzal et al, 2015;Lahiff et al, 2016;Calabrò et al, 2018) and assistive devices (Rao et al, 2008;Awad et al, 2017;Bae et al, 2018) to improve walking patterns in individuals with gait asymmetries, such as individuals poststroke. While these apparatus could reduce the metabolic cost associated to gait in this clinical population (Awad et al, 2017) and improve walking speed (Rao et al, 2008;Buesing et al, 2015;Calabrò et al, 2018), these devices were unsuccessful in modifying the step length asymmetry (Handzic et al, 2011), which is an important parameter in rehabilitation of post-stroke patients (Patterson et al, 2008(Patterson et al, , 2014. For example, Lahiff et al (2016) were able to modify push-off and breaking forces, but their device was unable to change step length of the participants.…”

The motor system has the flexibility to update motor plans according to systematic changes in the environment or the body. This capacity is studied in the laboratory through sensorimotor adaptation paradigms imposing sustained and predictable motor demands specific to the task at hand. However, these studies are tied to the laboratory setting. Thus, we asked if a portable device could be used to elicit locomotor adaptation outside the laboratory. To this end, we tested the extent to which a pair of motorized shoes could induce similar locomotor adaptation to split-belt walking, which is a well-established sensorimotor adaptation paradigm in locomotion. We specifically compared the adaptation effects (i.e. after-effects) between two groups of young, healthy participants walking with the legs moving at different speeds by either a split-belt treadmill or a pair of motorized shoes. The speeds at which the legs moved in the splitbelt group was set by the belt speed under each foot, whereas in the motorized shoes group were set by the combined effect of the actuated shoes and the belts' moving at the same speed. We found that the adaptation of joint motions and measures of spatial and temporal asymmetry, which are commonly used to quantify sensorimotor adaptation in locomotion, were indistinguishable between groups. We only found small differences in the joint angle kinematics during baseline walking between the groupspotentially due to the weight and height of the motorized shoes. Our results indicate that robust sensorimotor adaptation in walking can be induced with a paired of motorized shoes, opening the exciting possibility to study sensorimotor adaptation during more realistic situations outside the laboratory.

“…AFO use results in increased medial-lateral ankle stability, which promotes a more normal walking pattern. 16 The different types of orthoses on the market may be dynamic or rigid, anterior or posterior, standard or made to measure, and constructed from different materials. All of these braces exert an effect on static and dynamic balance, walking speed, cadence, step length, and dynamic base.…”

Introduction: Stroke is currently the main cause of permanent disability in adults. The impairments are a combination of sensory, motor, cognitive and emotional changes that result in restrictions on the ability to perform basic activities of daily living (BADL). Postural control is affected and causes problems with static and dynamic balance, thus increasing the risk of falls and secondary injuries. The purpose of this review was to compile the literature to date, and assess the impact of ankle-foot orthosis (AFO) on postural control and gait in individuals who have suffered a stroke. Development:The review included randomised and controlled trials that examined the effects of AFO in stroke patients between 18 and 80 years old, with acute or chronic evolution. No search limits on the date of the studies were included, and the search lasted until April 2011. The following databases were used: Pubmed, Trip Database, Cochrane library, Embase, ISI Web Knowledge, CINHAL and PEDro. Intervention succeeded in improving some gait parameters, such as speed and cadence. However it is not clear if there was improvement in the symmetry, postural sway or balance.Conclusions: Because of the limitations of this systematic review, due to the clinical diversity of the studies and the methodological limitations, these results should be considered with caution.

El control postural se afecta y da lugar a problemas en el equilibrio estático y dinámico que incrementan el riesgo de caídas. El objetivo de la revisión consiste en realizar una revisión sistemática que permita valorar los efectos de las ortesis de tobillo (OTP) en el control postural y en la marcha, en sujetos que han presentado un ictus.Desarrollo: Se incluyeron ensayos controlados y aleatorizados que analizasen los efectos de las ortesis de tobillo en pacientes con ictus de entre 18 y 80 años, con evolución aguda o crónica. La búsqueda de ensayos no tuvo limitación en fecha de inicio y se extendió hasta marzo de 2011. Se emplearon las bases de datos Pubmed, Trip Database, Cochrane Library Plus, Embase, ISI Web knowledge, CINHAL y PEDro.Conclusiones: La intervención logró mejorar algunos parámetros de la marcha como velocidad y cadencia. Sin embargo, no está clara la mejora en la simetría del peso, el balanceo postural o el equilibrio. Las limitaciones de esta revisión sistemática, debidas a la gran diversidad clínica de los estudios que incluye y las limitaciones metodológicas de estos, justifican una lectura precavida de...
