Szczegółowy opis

Background Cerebral palsy (CP) is the most common motor disability in childhood, affecting movement, muscle tone, and posture as a result of a non-progressive lesion in the developing brain. Children with CP frequently present with alterations in gait and postural control that significantly impact their daily functioning and quality of life. Although conventional physical therapy remains the cornerstone of rehabilitation, adherence and motivation are persistent challenges, particularly in pediatric populations. Non-immersive virtual reality (VR) systems, such as Rehametrics, which use standard screens and motion-capture sensors rather than head-mounted displays, offer an interactive, game-based rehabilitation environment that may enhance motivation, promote repetitive motor practice, and provide objective performance metrics to clinicians.

Objective The primary aim of this study is to evaluate the feasibility and user satisfaction of a non-immersive VR rehabilitation system, i.e. Rehametrics, for gait and balance training in children with CP. Secondary objectives include assessing the system's impact on functional mobility, gross motor function, balance, active participation, and user experience.

Methods This is a pre-post single group pilot exploratory study. Ten children aged 4 to 10 years with a diagnosis of CP, confirmed by a pediatric neurologist, will be recruited from Centro Médico Pedro P. Diaz, Arequipa, Peru. Each participant will serve as their own control. The intervention consists of 9 sessions with Rehametrics, a non-immersive VR rehabilitation system designed to train gait and balance through interactive virtual scenarios. Outcome measures include: number of sessions completed, the User Satisfaction Evaluation Questionnaire (USEQ), the Timed Up and Go test (TUG), the Gross Motor Function Measure (GMFM-88), the Pediatric Balance Scale (PBS), the Pittsburgh Rehabilitation Participation Scale (PRPS), and the User Experience Questionnaire (UEQ). Pre- and post-intervention assessments will be conducted by a trained physical therapist blinded to session performance data. Statistical analysis will use paired Student's t-test for normally distributed continuous variables and non-parametric tests (Wilcoxon signed-rank) for ordinal data.

Results Recruitment has not yet commenced. Results from this pilot study are expected to provide preliminary estimates of effect size and feasibility parameters to inform the design of a larger controlled trial.

Conclusions This protocol describes a novel application of Rehametrics, as a rehabilitation tool for children with CP. Findings will contribute evidence on the feasibility, satisfaction and preliminary clinical outcomes of game-based VR training targeting gait and balance in a pediatric rehabilitation setting in a middle income country context.

Eksperymentalny: Feseability and User Satisfaction
Participant will use Rehametrics plataform for training balance and gait
Urządzenie: non inmersive VR System

The Rehametrics® platform is a CE-certified non-immersive virtual rehabilitation software that operates via a Microsoft Kinect sensor to capture full-body movement without contact-based sensors. . It provides over 80 motor, cognitive, and occupational therapy exercises structured as gamified tasks, with automatic difficulty adaptation based on real-time patient performance and multimodal feedback (visual, auditory, and performance). The system generates quantitative session reports, enabling clinicians to objectively monitor patient evolution over time.

To date, however, no published study has evaluated the Rehametrics system specifically in children with CP. Given the platform's CE medical device certification, its non-immersive, contact-free interaction mode, its capacity for progressive difficulty adaptation, particularly relevant for pediatric patients, and its ability to quantify motor performance objectively during sessions, it represents a clinically appropriate and technically

Gross Motor Function - GMFM-88
Ramy czasowe: Baseline, pre-intervention and immediately after the intervention
The Gross Motor Function Measure (GMFM-88) is a standardized, validated clinical observational instrument developed to evaluate gross motor function in children with CP (Russell et al., 2000, 2002). It comprises 88 items scored on a 4-point ordinal scale (0 = does not initiate, 1 = initiates task <10%, 2 = partially completes task 10-99%, 3 = completes task 100%; NT = not tested). Items are grouped into five dimensions: (A) Lying and Rolling, (B) Sitting, (C) Crawling and Kneeling, (D) Standing, (E) Walking, Running and Jumping. Dimension scores are expressed as percentages of the maximum possible score, and the total score is the mean of the five dimension percentages.

Balance - Pediatric Balance Scale (PBS)
Ramy czasowe: Baseline, pre-intervention, and immediately after the intervention
The Pediatric Balance Scale (PBS) is an adaptation of the Berg Balance Scale specifically designed to evaluate static and dynamic balance in children with neurological, musculoskeletal, or developmental conditions (Chia-ling et al., 2013). It comprises 14 functional tasks, each scored 0 to 4 (0 = unable to perform; 4 = performs independently and correctly). Tasks include: sit-to-stand, stand-to-sit, transfers, standing steady, feet-together standing, forward reach with extended arm, floor object retrieval from standing, turning to look behind, 360-degree turn, tandem standing, single-leg stance, single-leg balance, single-leg hopping, and standing on a soft surface.
Baseline, pre-intervention, and immediately after the intervention
Participation - Pittsburgh Rehabilitation Participation Scale (PRPS)
Ramy czasowe: immediately after the procedure (end-of-session rating by the physiotherapist).
The PRPS is a 6-point clinician-rated scale measuring active patient participation during rehabilitation sessions (Lenze et al., 2004). Ratings: 1 = no participation in any session; 2 = no participation in at least half of sessions; 3 = participation in most exercises without maximum effort or incomplete; 4 = good participation in all exercises with good effort, most completed; 5 = very good participation with maximum effort, all completed; 6 = excellent participation with maximum effort, all completed, and active interest shown. The physical therapist will complete the PRPS at the end of each session.

Ramy czasowe: Immediately after the Intervention
The User Experience Questionnaire description (UEQ) is a standardized instrument that evaluates six dimensions: (1) attractiveness, (2) efficiency, (3) perspicuity, (4) dependability, (5) stimulation, and (6) novelty. The UEQ comprises 26 items, rated on a 7-point Likert scale. The UEQ analyzes user experience results on a scale from -3 to +3, interpreted by ranges: 1.5 to 3.0 as very positive or excellent, 0.5 to 1.5 as positive or good, -0.5 to 0.5 as neutral, -1.5 to -0.5 as negative or low, and below -1.5 as very negative or poor. These ranges allow a quick assessment of the user's perception of the system

Rehametrics performance scores
Ramy czasowe: Immediately after the procedure (session 1-9).
At each session, the Rehametrics software automatically records and exports session-level kinematic performance data for each participant. These parameters include joint range of motion, base of support, displacement of the center of gravity, and step height and characteristics. Additionally, the system records exercise completion scores (proportion of tasks successfully completed per session), total active movement time, and difficulty level reached per exercise. These data will be extracted from the system's automatic clinical reports at the end of each session and compiled longitudinally to track intra-subject performance evolution across the 9 sessions.
