Purpose: Activity-based locomotor training improves intrinsic trunk control in children with spinal cord injury (SCI). To reinforce these improvements, there is a need to develop community integration activities to allow a patient to apply the retrained nervous system at home. One activity that has been explored is rocking in a rocking chair. This paper describes the design, fabrication, and evaluation of a rocking chair for children with SCI. Materials and Methods: The Quality Function Deployment (QFD) design process was used. Fundamental needs and features for the rocking chair were defined in a focus group with experienced therapists, and needs were then rated for importance. A House of Quality (HOQ) matrix was developed to correlate needs with design features, and a prototype design was generated. Virtual motion studies and finite element analysis (FEA) were utilized to assess the design. The chair was fabricated and physical testing was performed, including tipping and static and dynamic load assessments. Results and Conclusions: The needs identified through the QFD process were categorized into (1) safety, (2) therapeutic, (3) practical and aesthetic, and (4) data to track chair use. Features selected to meet these needs include safety stops, padding, straps, a stable base, armrests, adjustable footrest, and sensors to capture rocking data. FEA showed a factor of safety (FOS) > 5. Physical testing confirmed physical integrity, load-bearing capacity, and stability of the prototype glider rocking chair. The prototype provides a safe tool for further investigation of rocking for promotion of trunk muscle activation in children with SCI. IMPLICATIONS FOR REHABILITATION: Rocking in a rocking chair promotes carryover of gained trunk control capacity, from clinic to home in a population that is non-ambulatory. Rocking provides opportunity for self-practice in population with severely compromised capacity. Rocking is a movement that may be performed when other types of movement cannot be readily performed, e.g., resistance exercise, movement against gravity. Rocking creates opportunity for repetitive, voluntary, self-directed movement that is inherently pleasurable and reinforcing. [ABSTRACT FROM AUTHOR]
