[en] Introduction: children with cerebral palsy (CP), among them, children with spastic diplegia, can present functional alterations such as the reduction of joint ranges and muscle weakness, this closely related to the early appearance of fatigue during physical activity. These and other factors lead to alterations in gross motor function and restrictions on participation at home, at school and in the community. Currently, the benefits of strength programs in lower limbs have begun to be studied, as well as standing programs in children with CP, framed in interventions based on motor learning through play, as close as possible to the child's environment. Objective: to verify the effectiveness of a physiotherapy program of functional strength training combined with a standing program in children with CP. Material and methodology: a simple blind randomized controlled study was proposed with a sample of 36 children between 6 and 10 years old, diagnosed with CP of the spastic diplegia type, who are in levels I, II or III of the Gross Motor Function Classification System, GMFCS. The children will be divided in two groups, one of them will perform a functional strength program combined with a standing program (research group) and another will carry out the standing program (control group). Both groups will continue with their usual physiotherapy treatment. This intervention will last six months, during school period, and will contain 3 individual one-hour sessions per week, in which functional strength training will be addressed. In parallel, they will perform one hour of standing program per day, five times per week. All children will participate in a weekly group sport activity. Before (pre-intervention), during (post-intervention-1) and after (post-intervention-2 and follow-up) will be evaluated the following variables: joint range (goniometer), strength, muscular fatigue (dynamometer), gross motor (Gross Motor Function Measure, GMFM) and participation (PEM-CY and WeeFIM). Applicability: If the alternative hypothesis is confirmed, the strength program in combination with the standing program will show significant results after the intervention period, the improvement will be maintained during the follow-up and this will be greater than in the control group. Its impact on participation would represent an important advance in the approach of children with CP that could be extrapolated to other populations and other contexts.

[gl] Introdución: os/as nenos/as con parálise cerebral (PC), entre eles os/as nenos/as con diplejía espástica, poden presentar alteracións funcionais como son a diminución dos rangos articulares e a debilidade muscular, esta última estreitamente relacionada coa pronta aparición de fatiga durante a actividade física. Estes e outros factores, dan lugar a alteracións da motricidad grosa e restricións na participación no fogar, na escola e na comunidade. Na actualidade, están a comezarse a estudar os beneficios dos programas de forza en membros inferiores, así como do posicionamento en bipedestación en nenos/as con PC, enmarcados en intervencións baseadas na aprendizaxe motora a través do xogo, o máis próximos á contorna do neno/a. Obxectivo: comprobar a efectividade dun programa fisioterápico de adestramento funcional de forza compaxinado cun programa de bipedestación, en nenos con PC. Material e metodoloxía: exponse un estudo controlado aleatorizado simple cego cunha mostra de 36 nenos/as de entre 6 e 10 anos, diagnosticados/as de PC de tipo diplejía espástica, que se atopen nos niveis I, II ou III do sistema de clasificación da función motora grosa (Gross Motor Function Classification System, GMFCS). Estes serán divididos en dous grupos, un deles realizará un programa de forza funcional combinado cun programa de bipedestación (grupo de investigación) e outro realizará o programa de bipedestación (grupo control). Ambos os grupos continuarán co seu tratamento de fisioterapia habitual. Esta intervención levará a cabo durante seis meses, en período escolar, e conterá 3 sesións individuais por semana dunha hora de duración, nas que se abordará o traballo de forza funcional. Paralelamente, realizarase unha hora de bipedestación ao día, cinco veces por semana. Todos os/as nenos/as participarán nunha actividade deportiva grupal semanal. Antes (pre-intervención), durante (post-intervención-1) e despois (post-intervención-2 e seguimento) avaliaranse as variables de rango articular (goniómetro), forza, fatiga muscular (dinamómetro), motricidad grosa (Gross Motor Function Measure, GMFM) e participación (PEM-CY e WeeFIM). Aplicabilidade: Se se confirma a hipótese alternativa, o programa de forza en combinación co programa de bipedestación mostrará resultados significativos tras o período de intervención, manténdose o efecto durante o seguimento e sendo estes maiores que no grupo control. A súa repercusión na participación, suporía un avance importante na abordaxe dos/as nenos/as con PC que podería extrapolarse a outras poboacións e outros contextos.
