Feasibility of a Robot-Guided Active Play Intervention for Children With Cerebral Palsy (REACT)

4. november 2026 opdateret af: Julie Robillard, University of British Columbia

Robotic Engagement for Active Children's Therapy (REACT): NAO Cerebral Palsy Intervention

Cerebral palsy can make it difficult for children and adolescents to participate consistently in enjoyable physical activity. This study will examine whether a small humanoid robot called NAO can deliver a short, story-based active-play session that encourages movement and participation. Children and adolescents with cerebral palsy will complete one session at BC Children's Hospital. The study will assess whether the intervention is practical to deliver, acceptable to children and caregivers, and safe to use. Participants and caregivers will also provide feedback about their experience. The findings will be used to refine the intervention and plan a future larger trial.

Detaljeret beskrivelse

This is a single-session, single-arm, mixed-methods feasibility and acceptability study of a humanoid social robot-delivered, movement-based narrative active-play intervention for children and adolescents with cerebral palsy. The intervention is delivered by the NAO humanoid robot and is structured as a guided story in which the participant and robot move together through a sequence of physical actions. The intervention is designed around engagement and active participation rather than conventional prescriptive exercise delivery.

Participants across Gross Motor Function Classification System (GMFCS) Levels I-IV will complete an in-person session at BC Children's Hospital. The protocol includes parallel ambulatory and non-ambulatory versions that share a common narrative structure and movement library. During the session, behavioural, physiological, and movement-related information will be collected to characterize participant engagement and physical activity. Following the intervention, children or adolescents and their caregivers will complete measures related to engagement, exertion, comfort, acceptability, willingness to participate in the future, and their experience of the intervention. Semi-structured exit interviews will also be conducted.

The primary purpose of the study is to determine the feasibility and acceptability of delivering the intervention. Feasibility will be characterized using indicators including recruitment and consent, session completion, intervention fidelity, protocol deviations, adverse events, and measurement-protocol completeness. Qualitative feedback will be used to identify barriers, facilitators, and potential modifications to the intervention and study procedures.

The study is not designed or powered to evaluate intervention efficacy. Findings will instead be used to refine the intervention, study procedures, and outcome measures and to inform the design of a future definitive randomized controlled trial.

Eksperimentel: NAO-Guided Active Play Intervention

Participants will complete one in-person, NAO-delivered, movement-based narrative active-play session. The intervention includes parallel ambulatory (GMFCS I-III) and non-ambulatory (GMFCS IV) versions, with both versions sharing a common narrative structure and movement library.

A humanoid social robot (NAO, SoftBank Robotics) guides the participant through a single, story-based active-play session in which physical movements are embedded within a narrative. The intervention is designed to promote engagement and active participation rather than conventional prescriptive exercise delivery. Parallel ambulatory (GMFCS I-III) and non-ambulatory (GMFCS IV) versions are used, with both sharing a common narrative structure and movement library.

Child/adolescent engagement and intention to repeat the activity will be assessed using the age-appropriate REACT Post-Narrative Intervention Likert Scale (child version, ages 6-13; adolescent version, ages 14-18). Each version contains five items assessing enjoyment, desire to continue the activity, ease of performing the movements, experience interacting with NAO, and willingness to participate in a similar session again. Each item is rated from 1 to 5, with higher scores indicating a more positive response on that item. Responses will be summarized descriptively at the item level; no composite or total score will be calculated.

The survey contains 10 Likert items assessing perceived child enjoyment, engagement, comfort and safety, overall experience, willingness to participate again, willingness to participate in a longer program, comfort with use in therapy or at home, and willingness to recommend the session to other families. Each item is rated from 1 (strongly disagree) to 5 (strongly agree), with higher scores indicating greater agreement and a more positive response on that item. Responses will be summarized descriptively at the item level; no composite or total score will be calculated.

Child/adolescent perceptions of intervention length and comfort while wearing the arm-strap heart-rate monitor and wrist-worn accelerometer will be assessed using purpose-built questions and prompts in the REACT Facilitator Interview Guide. Participants will be asked whether the activity felt too long, too short, or appropriate in length and whether the study sensors caused discomfort or were noticeable during participation. Responses will be analyzed qualitatively; no numerical scale or composite score will be calculated.

OMNI Rating of Perceived Exertion Scale: Perceived Exertion
Tidsramme: Immediately following the approximately 12-minute intervention

Child/adolescent perceived exertion will be assessed using the cerebral palsy-specific OMNI Rating of Perceived Exertion scale, with ambulatory and non-ambulatory pictorial versions used as appropriate. The scale ranges from 0 ("not tired at all") to 10 ("very, very tired"), with higher scores indicating greater perceived exertion. Higher scores do not inherently represent a better or worse outcome.
