[en] Introduction: children and adolescents with disabilities usually have gait disturbances. Despite this, gait can be functional, favoring their autonomy and participation in the community. To achieve this goal from the field of physiotherapy, different techniques and instruments have been included, such as the recent incorporation of robotic systems (SR) and virtual reality (VR). This combination is having evidence in the therapy with adults, however, although there have been certain positive effects, in children it is necessary to continue researching to establish an optimal dosage and conclude in terms of the benefits. Also it is important to study other pathologies different from cerebral palsy, the population selected in most studies. One of the disadvantage SR presents is the high cost of the systems, which makes difficult to include them in daily practice, such as in the school environment. So, the following project has been considered, which includes the use of a SR prototype in combination with RV, both low cost systems. The objective is to verify the effectiveness of the prototype and see its effects on the progress of children and adolescents with DF. Methodology: in order to check the feasibility of the use of SR, we propose this research project for conducting a pilot study. A total of 36 participants between 7 and 16 years old with a pathology of neurological origin will be recruited, who will be randomly distributed in two groups of equal size. The first one will receive the intervention with the SR + RV, which will be complemented with the physiotherapy sessions that it receives on a regular basis. The second one will only receive this last type of intervention. It will take place during two months, in which the intervention group will have 30 minutes sessions, three times a week. Previously, a blind evaluation of the following aspects will be carried out gait functionality (main variable), energy expenditure, muscle activation, balance, spatiotemporal parameters of gait, gross motor function, daily life activities and dependence and, finally, participation. After the intervention period, it will be repeated, as then two months after to really see the effects in the medium term. Applicability: the objective of this study is to see the effectiveness of the SR and the methodology proposed to carry out a randomized clinical trial, as well as contribute with new data on this type of intervention. If good results are obtained, they would be disseminated to the community in order to divulge its use.

[gl] Introdución: os nenos/as e adolescentes que presentan diversidade funcional (DF) soen ter alteracións da marcha. A pesar disto, esta pode ser funcional, favorencendo a súa autonomía e participación na comunidad. Para lograr dito obxectivo dende o ámbito da fisioterapia fóronse incluíndo distintas técnicas e instrumentos, como pode ser a recente incorporación de novas tecnoloxías a través de sistemas robotizados (SR) e realidade virtual (RV). Esta vai tendo evidencia na terapia con adultos, pola contra, aínda que se viron certos efectos positivos, en nenos é necesario seguir investigando para establecer una dosificación óptima e concluír en canto aos beneficios que aporta, ademais de estudar outras patoloxías diferentes á parálise cerebral (PC), poboación seleccionada na maioría de estudos. Un dos inconvenientes que presenta, é o elevado custo dos sistemas, o que dificulta a súa inclusión na práctica diaria, como poder ser no ámbito escolar. Así, considerouse a realización do seguinte proxecto, que inclúe o emprego dun prototipo de SR en combinación con RV, ambos de baixo custo. O obxectivo é comprobar a eficacia do prototipo e ver os efectos que ten sobre a marcha de nenos/as e adolescentes con DF. Metodoloxía: para isto plantéxase este proxecto de investigación no que se proxecta a realización dun estudo piloto. Reclutarase un total de 36 participantes de entre 7 e 16 anos con patoloxía de orixe neurolóxica, que serán distribuídos de forma aleatoria en dous grupos de igual tamaño. O primerio, recibirá a intervención co SR+RV, complementada coas sesións de fisioterapia que reciba de forma habitual. O segundo, só recibirá esta última. Levarase a cabo durante dous meses, nos cales o grupo de SR+RV terá sesións de 30 minutos tres veces por semana. Previamente, realizarase una evaluación cega dos seguintes aspectos: a funcionalidade da marcha (variable principal), o gasto enerxético, a activación muscular, o equilibrio, parámetros espacio-temporais da marcha, a función motora grosa, as actividades da vida diaria e dependencia e, finalmente, a participación. Tras o periodo de intervención, volverase a repetir, ao igual que ao cabo de dous meses para ver os efectos a medio prazo. Aplicabilidade: preténdese ver a eficacia do SR e da metodoloxía plantexada para logo realizar un ensaio clínico aleatorizado, así como aportar novos datos sobre este tipo de intervención. De ser bos os resultados, difundiranse para fomentar o seu emprego.
