Tactile Interaction with Socially Assistive Robots for Children with Physical Disabilities

Area of Science:

• Robotics in Rehabilitation
• Pediatric Physical Therapy
• Human-Robot Interaction

Background:

• Socially assistive robots (SARs) are increasingly used in pediatric rehabilitation to boost motivation and engagement.
• Current research on SARs predominantly explores verbal and visual interactions, with limited understanding of tactile (physical touch) engagement.
• Children with physical disabilities, including cerebral palsy (CP), could benefit from enhanced tactile interaction in robotic therapies.

Purpose of the Study:

• To conduct a scoping review of empirical studies on tactile interaction between SARs and children with physical disabilities.
• To identify and analyze research published between 2010 and 2024 focusing on touch-based SAR interventions in pediatric rehabilitation.

Main Methods:

• A systematic search and selection process was employed to identify relevant empirical studies.
• Nine studies met the eligibility criteria for inclusion in the review.
• The review focused on the application and measurement of tactile interaction in SAR-based pediatric physical therapy.

Main Results:

• Touch-based SAR interventions are utilized in pediatric rehabilitation, but lack standardized methodologies for assessing tactile engagement.
• Few studies have rigorously evaluated the therapeutic outcomes of touch-sensitive SARs.
• There is a significant need for validated frameworks to measure the efficacy of tactile interaction in SARs for children.

Conclusions:

• While tactile interaction shows promise in SAR-assisted pediatric rehabilitation, current research lacks structured approaches and measurement tools.
• Further research is required to develop and validate frameworks for assessing the therapeutic effects of touch-sensitive SARs.
• This review provides insights for researchers, specialists, and designers on optimizing tactile interaction in SARs for physical therapy.
