Descripción detallada

This is a pre-post, single-center, quasi-experimental study with an estimated duration of 17 weeks. The study will be conducted at Som·hi where a minimum of 10 evaluable participants are expected to be recruited within a period of 11 weeks.

After obtaining informed consent, through the Patient Information Sheet and the Informed Consent Form, the selection of the participants will be carried out to determine their inclusion in the study. Subjects who do not meet all the inclusion and exclusion criteria during the screening visit will be excluded from the study. At the latest, one week after the screening visit, the participants will undergo a baseline assessment without the medical device.

Participants will undergo a 10-session training program with the ABLE Kids device for a maximum duration of 3 weeks. Sessions will be conducted 5 times per week. Each session will last approximately 60 minutes. During the training period, session data will be taken to assess the safety and clinical performance of the device. At the latest, one week after the last training session, a post-training assessment will be performed. Finally, two weeks after the last training session, a follow-up assessment will be made to the participants via a telephone call to review any adverse events (AE) reported between the end of the training and the follow-up.

Gross Motor Function Measure-88
Periodo de tiempo: At baseline (day 0) and post-training (up to 4 weeks)
The Gross Motor Function Measure-88 (GMFM-88) is a standardized observational instrument designed to assess changes in gross motor function in children with motor impairments. It consists of 88 items grouped into five dimensions: lying and rolling, sitting, crawling and kneeling, standing, and walking/running/jumping. Each item is scored on a 4-point ordinal scale, with higher scores indicating better gross motor performance.

Motor Function Measure-20
Periodo de tiempo: At baseline (day 0) and post-training (up to 4 weeks)
The Motor Function Measure-20 (MFM-20) is a validated scale used to assess motor function in children with neuromuscular disorders. It evaluates functional abilities across three domains: standing position and transfers, axial and proximal motor function, and distal motor function. The scale consists of 20 items scored on a 4-point ordinal scale, with higher scores reflecting better motor performance.
At baseline (day 0) and post-training (up to 4 weeks)
Modified Ashworth Scale (MAS)
Periodo de tiempo: At selection, baseline and post-training (up to 4 weeks)
The Modified Ashworth Scale (MAS) measures spasticity in patients with lesions to the central nervous system. The scale assigns a grade of spasticity from 0 (no increase in muscle tone) to 4 (affected part rigid in flexion or extension).
At selection, baseline and post-training (up to 4 weeks)
Lower extremity muscle strength
Periodo de tiempo: At baseline (day 0) and post-training (up to 4 weeks)
The Daniels Muscle Testing scale will be used to measure the strength of muscles in the lower extremities. Scores range from 0 (absence of muscle activity) to 5 (normal muscle activity)

10-Meter Walk Test (10MWT)
Periodo de tiempo: At baseline (day 0) and post-training (up to 4 weeks)
The 10-Meter Walk Test (10MWT) measures the time a person needs to walk 10 meters. This test will be performed in the pre-post evaluations without the device to assess the change in the walking function after the training.
At baseline (day 0) and post-training (up to 4 weeks)
2-Minute Walk Test (2MWT)
Periodo de tiempo: At baseline (day 0) and post-training (up to 4 weeks)
The 2-Minute Walk Test (2MWT) measures the distance a person can walk in 2 minutes. This test will be assessed at baseline and at the end of the gait training program without the device to assess the change in the walking function after the training
At baseline (day 0) and post-training (up to 4 weeks)
Pediatric Balance Scale (PBS)
Periodo de tiempo: At baseline and post-training (up to 4 weeks)
The Pediatric Balance Scale (PBS) is a standardized clinical assessment used to evaluate functional balance in children. Adapted from the Berg Balance Scale, it consists of 14 tasks commonly performed in everyday activities, such as sitting, standing, reaching, turning, and transferring. Each item is scored on a 5-point scale from 0 to 4, with higher scores indicating better balance performance.
At baseline and post-training (up to 4 weeks)
Location and level of pain - Faces Pain Scale-Revised
Periodo de tiempo: From baseline to post-training (up to 4 weeks)
The Faces Pain Scale-Revised (FPS-R) is a self-report instrument used to assess pain intensity in children. The scale presents a series of faces representing increasing levels of pain intensity, allowing participants to select the face that best matches their pain experience. Pain location is additionally recorded based on the participant's report. Higher scores indicate greater pain intensity.
From baseline to post-training (up to 4 weeks)
OMNI Rating of Perceived Exertion
Periodo de tiempo: From baseline to post-training (up to 4 weeks)
The OMNI Rating of Perceived Exertion Scale is a validated self-report measure used to assess perceived physical effort during exercise in pediatric populations. The scale combines numerical ratings with verbal descriptors and pictorial representations to help children quantify their level of exertion during physical activity. Higher scores indicate greater perceived exertion.
From baseline to post-training (up to 4 weeks)
Functional Independence Measure for Children (WeeFIM)
Periodo de tiempo: At baseline and post-training (up to 4 weeks)
The Functional Independence Measure for Children (WeeFIM) is a standardized instrument used to assess functional independence in children. It evaluates performance in self-care, mobility, and cognition through 18 items scored on a 7-level scale, where 1 indicates total assistance and 7 indicates complete independence. Higher scores reflect greater functional independence in activities of daily living.
At baseline and post-training (up to 4 weeks)
Self-perceived impact on general health status
Periodo de tiempo: At post-training (up to 4 weeks)
Participants' perceptions of the impact on their general health will be evaluated by the completion of a self-report questionnaire on the perceived impact on general health. This questionnaire has been designed by the researchers and intends to identify to what extent participants feel that the ABLE Kids contributed to a change in their health. The questionnaire covers 7 categories (cardiovascular system, musculoskeletal pain, neuropathic pain, bladder and bowel, skin, spasticity, and sleep quality) using a 7-point Likert scale to assess the change.
At post-training (up to 4 weeks)
Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) score
Periodo de tiempo: At post-training (up to 4 weeks)
The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) is a 12-item outcome measure that assesses user satisfaction with two components (Device and Services) using a 5-point scale ranging from 1 (not satisfied) to 5 (very satisfied). Only the 8 items referred to the device will be evaluated from participants and the whole 12 items from the therapists to measure user satisfaction with the ABLE Kids after the training program experience
At post-training (up to 4 weeks)
EuroQol 5 Dimensions Youth - 5 Levels (EQ-5D-Y-5L)
Periodo de tiempo: At baseline and post-training (up to 4 weeks)
The EQ-5D-Y-5L is a standardized self-reported instrument used to assess health-related quality of life in children and adolescents. It evaluates five dimensions: mobility, looking after myself, doing usual activities, having pain or discomfort, and feeling worried, sad, or unhappy. Each dimension is rated on a 5-level scale ranging from "no problems" to "extreme problems." The instrument also includes a EuroQol Visual Analogue Scale (EQ VAS) for the participant's overall perception of their health status.
At baseline and post-training (up to 4 weeks)
