Individuals with spinal cord injuries (SCI) report low physical activity participation levels. A lack of physical activity can lead to increased secondary health concerns, such as cardiovascular, psychological, genitourinary, and musculoskeletal complications. Adaptive sports, such as quad rugby, allow individuals with SCI to maintain appropriate physical activity levels. This grounded theory study aimed to explore the experiences of individuals learning about and participating in quad rugby after SCI in the United States. Twelve participants from seven states across the United States completed semistructured interviews. Four themes emerged: benefits of quad rugby participation, enabling quad rugby participation, barriers to quad rugby participation, and motivation for continued participation in quad rugby. This study highlights the importance of an early introduction to quad rugby after SCI and the biopsychosocial benefits of participation. Occupational therapy practitioners can address barriers identified in this study through innovative approaches and advocacy efforts.
