ROBO-PAWS: Robot-Dog-Assisted Walking (ROBO-PAWS)
ROBO-PAWS: A Pilot Randomized Controlled Trial of Robot-Dog-Assisted Walking to Improve Sleep Quality, Fatigue, and Quality of Life in Pediatric Oncology Patients
Childhood cancers affect approximately 400,000 children and adolescents worldwide each year. Although advances in treatment have significantly improved survival rates, children undergoing cancer treatment continue to experience a wide range of treatment-related symptoms and complications. Among these, fatigue and sleep disturbances are particularly common and may persist throughout treatment and survivorship, negatively affecting psychological well-being, cognitive functioning, and overall quality of life. Reduced physical activity during treatment is strongly associated with worsening fatigue, impaired sleep, and decreased quality of life in pediatric oncology patients. However, treatment side effects, prolonged hospitalization, infection risk, and lack of motivating play-based activities often limit children's participation in physical activity during treatment. Recent evidence suggests that physical activity interventions may help reduce fatigue and improve well-being in children with cancer, yet engaging and age-appropriate non-pharmacological interventions remain limited, especially for younger children.
This pilot randomized controlled trial aims to evaluate the feasibility and potential effects of a robot-dog-assisted walking intervention on sleep quality, fatigue, and quality of life among children aged 2-7 years undergoing cancer treatment.

Descripción detallada
This pilot randomized controlled trial will evaluate the feasibility and preliminary effects of a robot-dog-assisted walking intervention for children aged 2-7 years receiving active cancer treatment. The intervention is designed to promote physical activity through interactive and play-based walking sessions supported by a robotic dog companion.
Children undergoing cancer treatment frequently experience fatigue, sleep disturbances, reduced physical activity, and decreased quality of life during treatment. Hospitalization, treatment-related side effects, infection precautions, and limited access to motivating activities may contribute to sedentary behaviors in this population. Previous studies have suggested that physical activity interventions may improve symptom management and well-being in pediatric oncology patients; however, engaging and developmentally appropriate interventions for young children remain limited.
Participants will be randomly assigned to either the robot-dog-assisted walking intervention group or the control group receiving standard care. The intervention will consist of structured walking activities integrated into the child's routine during hospitalization or outpatient treatment visits. Feasibility outcomes will include recruitment, retention, adherence, acceptability, and safety of the intervention. Preliminary clinical outcomes will include sleep quality, fatigue, and quality of life.
The findings of this study will provide preliminary evidence regarding the feasibility and potential benefits of integrating robot-assisted play and movement interventions into supportive pediatric oncology care.

Inclusion Criteria:
- Aged between 2 and 7 years,
- Diagnosed with cancer and currently receiving active treatment,
- Pain level not severe enough to interfere with mobilization (FLACC or Wong-Baker FACES score ≤ 4),
- Diagnosed within the previous 1 month,
- Medically stable and approved by the physician to participate in light-intensity walking activities,
- Expected to remain hospitalized for at least 1 month to allow completion of the study protocol,
- Not scheduled for hematopoietic stem cell transplantation (HSCT) and not currently undergoing HSCT,
- Hemoglobin level adequate for participation in walking activities (>10 g/dL),
- No significant impairment in consciousness, balance, or motor functions due to heavy analgesic or sedative medication use.
Exclusion Criteria:
- Resting SpO₂ <94%, requirement for ≥2 L/min oxygen support, or recurrent desaturation episodes within the last 24 hours,
- Heart rate or respiratory rate significantly elevated or irregular for age,
- Hemodynamic instability,
- Visual, hearing, or severe cognitive impairment that would prevent interaction with the robotic dog,
- Increased mobilization risk due to high-dose corticosteroid treatment or medications associated with neurotoxicity,
- Motor function limitations that would interfere with safe walking,
- Concurrent severe infection or serious treatment-related complications (e.g., grade 3-4 mucositis or severe neutropenia requiring isolation),
- Children receiving end-of-life care.

Experimental: ROBO-PAWS Group
Children in the intervention group will receive standard care in addition to participating in robot-dog-assisted walking sessions twice daily (morning and evening) for one month. Each walking session will last 15 minutes and will be conducted within the clinical setting under the supervision of a nurse/researcher to ensure participant safety. The total daily walking duration will be 30 minutes. Before the intervention and after completion of the intervention period, parents will complete questionnaires assessing sleep quality, quality of life, and fatigue. If the child experiences fatigue, dizziness, discomfort, or any other adverse symptoms during the walking sessions, the intervention will be immediately discontinued. The robotic dog will be disinfected before each use to maintain hygiene and infection control standards. |
The intervention will use AIBO (Sony Interactive Entertainment, ERS-1000), an artificial intelligence-based robotic dog designed to support social interaction and engagement with children. AIBO is equipped with advanced sensors, interactive movement capabilities, microphones, speakers, and touch-responsive features that allow it to respond to voice commands, physical contact, and environmental stimuli. Its natural dog-like movements, facial expressions displayed through OLED eyes, and playful behaviors are intended to attract children's attention and encourage participation in walking activities. In addition, the device includes motion and distance sensors that enable safe navigation within the clinical environment. Participants in the intervention group will receive standard medical and nursing care in addition to a robot-dog-assisted walking intervention using AIBO (Sony Interactive Entertainment, ERS-1000). Children will participate in supervised walking sessions twice daily (mornin |

Sin intervención: Control Group
Children in the control group will receive standard medical treatment and routine nursing care only.
Within routine clinical practice, children are allowed to leave their rooms and walk freely when they wish, although they are generally on bed rest for most of the day.
They may also participate in unstructured playroom activities such as reading books, drawing, or playing games.
However, no structured or supervised physical activity program aimed at increasing physical activity levels is routinely provided.
Therefore, children in the control group will continue their usual daily activities within the standard clinical care environment.

The scale evaluates physical, emotional, social, and school functioning.
Items are scored on a 0-100 scale, with higher scores indicating better perceived quality of life.
Total Scale Score, Physical Health Summary Score, and Psychosocial Health Summary Score will be calculated.
Parent proxy-reports will be used in this study.

Fatigue
Periodo de tiempo: Baseline (Day 1, prior to intervention initiation) and Week 4 (post-intervention assessment after completion of the 4-week intervention period).

Fatigue will be assessed using the Visual Fatigue Scale, a single-item self-report measure developed to evaluate fatigue severity.
The scale ranges from 0 ("No fatigue") to 10 ("Severe and overwhelming fatigue").
Higher scores indicate greater fatigue severity.
The instrument has demonstrated acceptable validity and reliability in clinical populations and will be used to monitor changes in fatigue levels throughout the intervention period.
