Efficacy of a Rehabilitation Program With the Pediatric Exoskeleton ATLAS 2030 in Pediatric Patients With Cerebral Palsy

Study Overview
=================
Brief Summary
-----------------
Cerebral Palsy (CP) is the first cause of motor disability in children worldwide. ATLAS 2030 is a robotic gait exoskeleton designed to rehabilitate children with motor disability. The objective of this study is to analyse the efficacy of a training program with ATLAS 2023 in chilren with CP.

Detailed Description
-----------------
A sample of children with CP will be divided into 2 groups, the experimental group will receive 32 sesions withe the ATLAS 2030 exoskeleton, whereas the control group will continue to receive their regular conventional therapy. Assessments will be performed at the beginning and the end of the intervention, as well as after 6, 9 and 12 months of the end of the intervention for follow-up.

Eligibility Criteria
-----------------
Inclusion Criteria: Medical authorization for standing, gait training and weight bearing. Informed consent signed by legal guardians. Confirmed diagnosis of cerebral palsy GMFCS levels III or IV.

Tibia leg length (distance from the lateral condyle of the tibia to the lateral malleolus) from 23cm to 32cm. Shoe size 27-33 (EU) Exclusion Criteria: More than 8 sessions of robotic therapy during a month in the previous year to the beginning of the study. Intensive rehabilitation during the study. Imposibility of the family to fulfill treatment calendar. Spasticity equal to 4 on the Modified Ashworth Scale at the time of use of the device. More than 20º of hip and/or knee flessum at the time of using the exoskeleton. Necessity to walk with 10º of hip abduction. Necessity to walk with more than 9º of ankle dorsiflexion or plantar flexion or impossibility to use an orthosis to reach 90º in the ankle joint. Severe skin lesion on parts of the lower extremities that are in contact with the device. Scheduled surgery (rachis, limbs) for the duration of the study or surgery performed (rachis, extremities) in the last 6 months. History of fracture without trauma. History of bone fracture traumatic in lower extremities or pelvic girdle in the last 3 months. Severe rigid orthopedic deformities of the spine and/or lower limbs. Cognitive or conductual disorders that may lead to a lack of adherence to the attachment to the device. Conditions that provoke exercise intolerance. Conductual disorders that may interfere with the use of the device or their participation in the study, like impulsiveness or the inability to understand simple comands. Allergy to any of the ATLAS materials: cotton, nylon, polyester, polyamide, polyethylene or propylene.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gross Motor Function Measure-88 (GMFM-88) | To measure changes in gross motor function in children with cerebral palsy using the Gross Motor Functional Measure-88. The minimum value is 0 and the maximum value is 100 .When the GMFM score is lower, the skill level is lower. | At the beginning and the end of the intervention (4 months), as well as after 6, 9 and 12 months (follow-up) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Modified Ashworth Scale (MAS) | changes in spasticity measured by the Modified Ashworth Scale (MAS). The spasticity of each muscle group is measured with a scale scored from 0 to 4, where 0 means no spasticity and 4 means the joint is fixed and therefore, the highest level of spasticity | Through study completion, along 1 year | 
| Pediatric Quality of Life Inventory (PedsQLTM) | Changes in self perceived quality of life measured by the Pediatric Quality of Life Inventory (PedsQLTM). Every item is measured on a scale from 0 (higher quality of life) to 4 (lower quality of life) | At the beginning and the end of the intervention (4 months), as well as after 6, 9 and 12 months (follow-up) | 
| Changes in Gait Deviation Index (GDI) | Changes in Gait Deviation Index (GDI) measured with a tridimensional motion analysis system | At the beginning and the end of the intervention (4 months), as well as after 6, 9 and 12 months (follow-up) |
