About this study

Official title: Effect of Physiotherapy Based on Robot Assited Gait Training on Body Composition and Functional Variables in Pediatric Patient With Neurodevelopmental Alterations: Randomized and Crossover Clinical Trial

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:

  • Does this treatment improve body composition parameters?
  • Does the treatment help maintaining functionality and without causing discomfort or pain?

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.

Read the detailed description

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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Robot assisted gait training plus conventional physical therapyCombination product

    Participants will complete 8 weeks of intervention of robot assisted gait training with the ATLAS 2030 exoskeleton (Marsi Bionics) owned by the school which they attend to. They will have 2 weekly sessions (16 sessions in total) for 4 weeks. Each session will last up to 1 hour (depending on the child's tolerance) although a minimum of 30 minutes per session and a minimum of 12 sessions will be set in this time. The training mode will be automatic. In addition, they will continue to carry out the rest of their usual treatments.

  • Conventional pjysical therapyOther

    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.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body composition, fat % (time frame: Before phase 1 (T1, pre intervention), after phase 1 (T2, after 8 weeks intervention), before phase 2 (T3, pre intervention) and after phase 2 (T4, after 8 weeks intervention).). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06645795, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026; AzTrials last refreshed its copy on 26 Oct 2026.
