Brief summary

Neurodevelopmental disorders often lead to abnormal development of the Central Nervous System (CNS), frequently causing motor dysfunctions such as an inability to stand and walk. EXPLORER is a robotic gait exoskeleton designed to rehabilitate children with motor disabilities in home and outdoor environments. The aim of this study is to evaluate the efficacy and usability of EXPLORER in children with motor disability within their natural settings, including home and community environments.

Detailed description

Neurodevelopmental disorders often lead to abnormal development of the Central Nervous System (CNS), frequently causing motor dysfunctions such as an inability to stand and walk. Robotic devices are a useful tool in the rehabilitation of these children, but most of them are designed to be used in the clinical setting. EXPLORER is a robotic device designed to assist gait in children with motor disability in their homes and the community. The aim of this study is to evaluate the efficacy and usability of EXPLORER in children with motor disability within their natural settings, including home and community environments. An initial session will be conducted in the participant's natural environment, during which the researchers will instruct the primary caregivers on the use of the device. Subsequently, the device will be left for a two-month period for use in the natural settings deemed appropriate by the family.

Inclusion criteria

* Diagnosis of any pathology or condition causing neurodevelopmental disorders. * Ability to continuously use the device for two weeks, at least 3 times per week, without causing excessive fatigue that would prevent the participant from carrying out their usual activities. * Availability and commitment from the family to use the device at least 3 times per week during the planned period, in different environments and with various objectives. * Medical authorization for standing, gait training and weight bearing. * Informed consent signed by legal guardians. * Maximum user weight of 60 kg. * Hip width (between greater trochanters) ≤37 cm. * Length of the thigh (distance from the greater trochanter to the lateral condyle of the tibia) from 21cm to 36cm. * Tibia leg length (distance from the lateral condyle of the tibia to the lateral malleolus) from 20cm to 35cm. * Shoe size ≤40 (EU)

Exclusion criteria

* Medical contraindications for standing or walking. * Non-reducible contractures or heterotropic ossifications above the degrees allowed by the device or out of the trajectory imposed by the device * 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 non-reducible contractures at the time of using the exoskeleton. * Necessity to walk with more than 5º of hip abduction. * Impossibility to reach 5º of ankle dorsiflexion with ir without orthoses. * Lower length dysmetria that cannot be mitigated with a wedge under the foot. * Skin lesion on parts of the lower extremities that are in contact with the device. * History of fracture without trauma. * Presence of other conditions causing exercise intolerance (such as uncontrolled hypertension, coronary artery disease, arrhythmia, congestive heart failure, severe pulmonary disease). * Conductual disorders that may interfere with the use of the device or their participation in the study, like impulsiveness. * Allergy to any of the EXPLORER materials: cotton, nylon, polyester, PPS, PEEK or ABS.

MeasureTime frameDescription
ParticipationBefore starting the intervention (S1) and after completing the two weeks of useMeasured with the Child and Adolescent Scale of Participation. 20 ordinal scaled items across 4 subsections. Maximum total score is 80 (20 items x 4) and the minimum total score is 20 (20 items x 1)
Serious Adverse Eventsthrough study completion, along 2 weeksoccurrence of any serious adverse event to the participant or the caregiver
Falls prevalencethrough study completion, along 2 weeksNumber of falling events occurred from the participant or caregiver
Skin integritythrough study completion, along 2 weeksOccurrence of any injury of the skin in the areas of contact and produced by the use of the device
Pain (Visual Analogic Scale)through study completion, along 2 weekspain measured by the Visual Analogic Scale (VAS) by the participant and the caregiver, scored from 0 to 10, being 0 no pain and 10 unbearable pain
Donning and doffing timethrough study completion, along 2 weeksTime to don and doff the device to each participant
Device usage timethrough study completion, along 2 weeksTime using the device
Number of stepsthrough study completion, along 2 weeksnumber of steps with the device
Usage modesthrough study completion, along 2 weekstwo different usage modes (active and automatic).
Speedthrough study completion, along 2 weeksspeed achieved with the device (steps per minute)
Device accessibilitythrough study completion, along 2 weeksEnvironments where the device has been used and level of accessibility in each environment measured with a 5 points Likert scale (0 not accessible - 5 very accessible)
Range of motionBefore starting the intervention (S1) and after completing the two weeks of usePassive Degree to which a joint can move (hip, knee, and ankle joints in both legs). From 0º to 180º.

Secondary

MeasureTime frameDescription
QUESTat the end of the interventionUsing the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) questionnaire administered to the participants' caregivers at the end of the intervention. The QUEST 2.0 scale has 12 items. Each item is rated on a 5-point Likert scale
