The aim of this randomized crossover clinical trial is to determine the effect of robot assisted gait training combined with physiotherapy on body composition and functional variables in a pediatric population with neurodevelopmental disorders.The main questions to answer are:
Participants will perform 2 weekly physiotherapy sessions for 8 weeks, then there will be 4 weeks of washout, afer which each patient will cross over to the other group for 8 more weeks.
Pediatric population with neurodevelopmental disorders, such as cerebral palsy (CP), levels IV-V of the Gross Motor Function Classification System (GMFCS), do not walk independently due to their significant physical limitations, so their body composition may be altered, which in turn affects their functional level and may lead to the appearance of musculoskeletal complications. Robot assisted gait training (RAGT) offers a new opportunity to improve mobility of pediatric population with CP levels IV-V of GMFCS, although scientific literature is still scarce in this population.
The main aim of this study is to determine the effect of RAGT on body composition and functional variables in a pediatric population with neurodevelopmental disorders. Also to analyze changes in functional, musculoeskeletal, and stress biomarkers variables after the intervention, and to evaluate the cardiorespiratory adaptation to the RAGT.
A convenience sample of 10-12 participants will be selected, who will serve as their own control. It has been taken into account that previous studies conducted on pediatric population with CP this sample size is adequate.
At the beginning of the study, 50% of the participants will be part of the RAGT group, which will perform 2 weekly sessions of RAGT plus conventional therapy; and the other 50% will belong to the conventional physical therapy group. The study consists of phases 1 and 2 of treatment with a washout period between phases: after "phase 1" (8 weeks of therapy in one of the two groups), there will be 4 weeks of washout, after which each patient will cross over to the other group in "phase 2" (for 8 weeks).
Participants will be assessed before phase 1 (T1), after phase 1 (T2), before phase 2 (T3) and after phase 2 (T4).

| Conventional pjysical therapy | Other | Participants will complete 8 weeks of conventional therapy, with 2 sessions per week (16 sessions total). During the conventional treatment period, participants will continue with the conventional physical therapy they have received thus far. The content of the usual care treatment does not specifically address gait training, but consists of elements addressing range of motion, tone reduction, balance, activities of daily living, etc. The conventional intervention may be different for each individual based on their needs (to represent usual care), however, participants will be advised not to change the intervention, type, and frequency during the study. |
